The impact of integrating Acceleration Technology into your practice Dr. Lou Shuman discusses the benefits of Ortho Acceleration

O

rthodontic Acceleration is on the threshold of forever changing how orthodontics is provided. The benefits of acceleration far outweigh any perceived barriers, and soon the consumer population will demand it as part of standard orthodontic care, as was the case with Invisalign®. The clinical literature demonstrating the efficacy of micro-osteoperforation abounds (for Propel clinical articles and case studies go to www.propelorthodontics.com), as well as studies that show patients are interested in accelerated treatment and willing to pay extra for reduced treatment time.1 This month’s column moves in a different direction — first, a personal opinion on Propel technology and then practice management tools that can accelerate practice growth in addition to clinical acceleration.

To start, what sets Propel apart as the most viable Accelerated Orthodontic option?

• It is doctor controlled and NOT patient controlled.

• That means you have a significantly better chance of more predictable results and promised time outcomes.

• It has the ability to target difficult movements and treat just one arch, which is critical for those with adult patients.

• As an orthodontist specializing in adults for many years, lower adult onset crowding was the single most common case I treated. After reviewing other orthodontic acceleration systems, I have difficulty accepting

technologies that impact the entire dentition when the treatment plan calls for treating only one arch.

Many times, it only takes one visit or application to provide 3-6 months of acceleration. This is far more efficient than relying on patients to be compliant on a daily basis and, in many cases, while also attempting to be compliant with aligner wear simultaneously.

•

•

It is by far the most cost-effective treatment available today2 with pricing as low as $100 per patient.

Similar to all Acceleration Technologies, your gross production per hour can easily double.

Your annual production is significantly increased as you have more open chair time for new patients by finishing cases so much faster.

INTRODUCTION

Seeking the high-fidelity occlusion

T

he armamentarium of the orthodontist has changed dramatically in the past several decades — from pre-formed stainless steel arches to nickel titanium and its many variations and from banded to direct-bonded to self-ligating appliances. I’m sure you can think of many other transitions.

Today, our society is in the midst of what can be called nothing less than the digital revolution. From newspapers to cooking utensils, everything is available digitally. Digital orthodontics is very much a part of this change in the way we do things.

Dr. J. Peter Kierl This has been observed often in the pages of this journal and put into practice every day in virtually (the next generation of orthodontics?) every office, whether acknowledged or not. Almost certainly, your scheduling is maintained on your office’s computer. And, in most practices, X-rays are digital, as is patient photography.

This comes as no great revelation. Still, the day-to-day practice of orthodontics is generally a hand-eye proposition. It is also true that, with every passing day, digital orthodontics is very much here and producing superior results in practices globally, in spite of the fact that many of us have been hesitant to adopt it across our entire practice.

Why? Because, in a word, it is change at a level never before experienced since the possibility of improving an individual’s occlusion was first considered. Straightening teeth is now as much a matter of pixels and the cloud as it is of mechanics and force.

Digital treatment of patients — from case planning to wire staging to communications — is here today and even more so tomorrow, as technologies become, at once, more sophisticated and affordable.

Perhaps the greatest shift in the practice of orthodontics brought on by the digital revolution is proactive rather than reactive treatment. In the pre-digital practice modality, we bonded (or banded) the patient; placed a low-force, leveling archwire; waited, watched, and reacted; and kept reacting until we reached a satisfactory result. In the digital practice, the role of treatment planning takes preeminence, providing us with the opportunity to plan the final occlusion using specific tooth-by-tooth movement.

In the old model, we basically knew where we wanted to go with each patient and worked to get there. In the digital model, we can analyze the patient’s malocclusion, specifically design its treatment, and achieve it. As an orthodontist, this not only gives us a new level of diagnostic sophistication, but also empowers us to see the future and contour it to our ideal goal.

When high fidelity (hi-fi) came to record players, it just sounded better. Listening expectations only grew as we learned to hear recorded (now mostly digital) music differently. The same shift in how we approach the occlusion is happening for us today. There is nothing more gratifying than being able to show patients my plan for their occlusion, knowing that I possess the clinical skills and tools to achieve that specific occlusion, not to mention with greater efficiency than ever before.

The high-fidelity occlusion means happier smiles all around. That’s what the digital revolution makes possible, achieving the optimal result for each and every patient.

OrthoAccel® Technologies, Inc. Eyeing significant market growth opportunities

F

aster orthodontic treatment has always been patients’ number one request.

According to a recent American Journal of Orthodontics and Dentofacial Orthopedics survey, orthodontists acknowledge that if they can reduce treatment time by 20% to 40%, then alternative techniques to accelerate tooth movement are attractive to them as well.1 The results are an evergrowing population of patients who want faster treatment and forward-thinking orthodontists who enthusiastically want to offer an accelerated option. It’s no coincidence that in the orthodontic industry, OrthoAccel® Technologies, Inc., is gaining rapid market share with AcceleDent®, an FDA-cleared, prescription-only Class II medical device that has proven to shorten orthodontic treatment by as much as 50%. With this safe and gentle treatment option, orthodontic patients simply use AcceleDent for 20 minutes a day while SoftPulse Technology® accelerates their tooth movement.

AcceleDent, the Leader in Accelerated Orthodontics™, is the first and only noninvasive technique that speeds orthodontic treatment. Since the company’s introduction to the U.S. market in 2012, AcceleDent is now offered in more than 2,300 provider locations throughout North America — and that number is growing daily. A recent Journal of Clinical Orthodontics’ survey underscores the company’s dynamic growth, stating that AcceleDent is the most common accelerated treatment technique used by orthodontists. In the survey, 62% of practices that use accelerated treatment reported that they occasionally or routinely use AcceleDent.2 Parallel to these reports and trends is OrthoAccel Technologies’ own story as a young startup company with an innovative new product — one many consider to be the first major orthodontic innovation in more than 15 years. OrthoAccel has experienced extreme growth each of the past 3 years, reporting an 80% increase in sales in 2014. The company’s progress has continued to impress investors, and in January 2015, OrthoAccel continued its recent transition to a blended debt and 10 Orthodontic practice

“Our stockholders and equity partners remain enthusiastic about our rapid market growth and what we’ve been able to accomplish in the U.S. and Canada in 3 short years,” said Mike Lowe, OrthoAccel’s president and CEO. “AcceleDent is the first to market in the category of non-invasive accelerated

orthodontic treatment techniques, so it’s up to us to continue educating orthodontists and consumers about the value of accelerated treatment while also continuing to push the envelope in the area of innovation.”

Growth milestones — industry and consumer

OrthoAccel Technologies’ President and CEO Mike Lowe is honored as one of Houston’s best and brightest young professionals at Houston Business Journal’s 40 Under 40 Awards.

Volume 6 Number 3

Lowe, who was named a Houston Business Journal “40 Under 40” honoree for his impressive contributions to the orthodontic industry and to Houston’s medical technology sector, attributes OrthoAccel’s business success to two factors: industry acceptance and consumer awareness.

“Our goal as a company is to improve patients’ journeys to healthy, beautiful smiles, and we believe that is a goal we share with every orthodontist,” said Lowe. “That’s why AcceleDent was integrated into more than 500 additional practices in 2014 alone.”

Lowe adds that industry acceptance is steadily increasing in part because leading orthodontists continue to share compelling AcceleDent patient case studies with their peers. Many of these orthodontists have adopted AcceleDent as standard of care in their practices. For example, Dr. Sonia Palleck of Woodstock, Ontario, was an early adopter and has already accelerated the treatment of more than 250 patients using AcceleDent. Salt Lake City, Utah-based Dr. John Graham, one of the first AcceleDent providers in the U.S., has successfully enhanced practice economics and efficiency through the adoption of non-invasive, accelerated orthodontic treatment.

“In more than a decade of practicing orthodontics, I’ve used several types of accelerated treatment options, but none compare to AcceleDent’s ability to provide faster treatment without compromising results,” said Graham. “By offering AcceleDent, I’m able to make my patients’ orthodontic experience faster and more pleasant, with many of my patients reporting less discomfort when using AcceleDent.”

In a recent independent study, 100% of patients surveyed reported that AcceleDent is easy to use and that they were satisfied with their experience using the technology.

The overwhelming majority of patients also said they would recommend AcceleDent to a family member or friend.

“More patients are asking their orthodontists about accelerated treatment with Orthodontic practice 11

recently recognized by the American Business Awards, Good Design Awards, and Best in Biz Awards.

CORPORATE PROFILE

“In more than a decade of practicing orthodontics, I’ve used several types of accelerated treatment options, but none compare to AcceleDent’s ability to provide faster treatment without compromising results.”

– Dr. John Graham, Salt Lake City, Utah AcceleDent, and more orthodontists are eager to offer AcceleDent because of widespread, positive patient results,” said Lowe.

“The momentum continues to build.”

AcceleDent use has been common among adolescents and adults and is particularly appealing to adults who once avoided orthodontic treatment because of length of treatment time. Research from the American Association of Orthodontists (AAO) revealed that adults report improved lifestyles after orthodontic treatment, with 83% stating they experienced an increase in interpersonal relationships and 58% stating an improved career success.3 OrthoAccel’s marketing and sales team has found that accelerated treatment with AcceleDent is particularly appealing to 12 Orthodontic practice

patients striving toward specific milestones such as weddings, graduations, proms, vacations, and career promotions.

More growth opportunities OrthoAccel’s dynamic growth in 2014 has attracted some of the orthodontic industry’s most experienced and recognizable names, helping Lowe double his sales team and round out his senior leadership team. Lowe’s executive management team includes Kathleen Malaspina, chief innovation officer and vice president of marketing; Kelly Enos, chief financial officer and vice president of finance and administration; Doug Bukaty, vice president of sales; and Jeff Layton, chief operations officer. Additionally, Lowe anticipates that the company’s continued growth

in 2015 will spur job creation in the areas of engineering, marketing, accounting, and administration.

With American Association of Orthodontists reporting an increasing number of orthodontic patients across all demographic segments, Lowe predicts steady growth in sales targets as well. In 2012, the U.S. had a 22% increase in adolescent orthodontic patients as compared to 2010, representing the largest number of non-adult orthodontic patients since the beginning of data collection recording. There was a 29% increase in adult patients during that same timeframe, another record high. And reflecting the trend of men becoming more esthetically conscious, there was a 44% increase in male orthodontic patients.4 “The market research clearly shows that AcceleDent is the premier choice for accelerating orthodontic treatment, and as this market continues to expand, integration of AcceleDent into orthodontic practices is primed to grow rapidly,” says Lowe. In addition, “brand awareness becomes more widespread daily as pleased patients share their AcceleDent testimonials with friends and family virally via social media.”

OrthoAccel is enthusiastic about the significant growth in provider numbers and the future for AcceleDent. “OrthoAccel’s mission is to deliver innovative and clinically impactful solutions to orthodontic specialists, and we are pleased to build on the success of the AcceleDent brand,” said Malaspina.

“Our entire team is eagerly anticipating the upcoming 2015 AAO in San Francisco, and we’re excited to again present a premier educational lecture schedule at Booth No. 615 with some of the industry’s top national and international practitioners. In addition, we have planned several creative and unique activities for conference guests to share their positive experiences with AcceleDent.”

CASE STUDY

The Baxmann Mini Telescope™ (BMT) in practical testing Dr. Martin Baxmann discusses an apparatus for Class II treatment

T

he lack of dependence on patient cooperation is one of the key issues for the long-term development of fixed Class II type equipment. This type of equipment is distinguished by a high level of efficiency, ease of use, high comfort in wear, and patient acceptance, all the while maintaining the lowest possible manufacturing costs.

Despite extensive development and the introduction of new concepts, this is yet to be fully achieved, and only limited progress has been achieved. Nevertheless, we can observe a continuous process of improvement in the existing equipment and constant development of new technologies. One of these promising new developments is the Baxmann Mini Telescope™ (BMT, Figure 1), produced and distributed by Adenta.

The specific purpose behind the development of the BMT was to create an apparatus that consists of a minimal number of individual parts, with an identical installation sequence for both sides of the jaw, in addition to the upper and lower parts of the jaw.

It is extremely intuitive and does not require elaborate laboratory work. This has been successfully achieved by taking an existing concept and rearranging it, thus creating a very compact, concise apparatus that is barely visible to the patient. It is also characterized by its small size and high comfort in wear, as well as freedom of movement.

A treatment kit consists of a complete apparatus including all accessories. Two kits are needed for symmetrical Class II therapy (kits for the right left side are identical). The apparatus consists of a telescopic tube and a telescopic pole, each with a mounting lug.

These include two pins for attachment. These are attached to the first molars with a band on the buccal tubes (headgear tubes). It is advisable to use double-welded loops in order to obtain the best possible shape and achieve a high level of stability of the bands even when very strong chewing forces are applied.

Correction of a bilateral Class II with a prominent lip In the case of a Class II in adolescents, there is the possibility to apply functional orthodontic treatment with removable

appliances, such as the Twin Block or similar equipment. In this situation, a complete permanent dentition was already present at the age of 11 years. It seemed effective to skip the pretreatment and combine the needed therapy with a multi-bracket appliance and the BMT (Figures 2A-2F: MB apparatus and BMT were used at the same time). During the leveling, only the molars are stabilized by the transpalatal and lingual arches. As a result, this treatment could be completed in just 16 months and proceed to the retention phase.

The BMT was removed after 10 months, so that finishing and initial settling could be achieved without the use of a fixed Class II device (Figures 3A-3C). The ability to loosen the apparatus during each appointment is especially useful in the application of the BMT. For this purpose, the telescoping rod is pulled out of the tube during a maximum passive opening of the mouth. This takes about a minute per side, including the reactivation phase. It is then possible to check the actual bite of the patient while avoiding phenomena such as a dual bite. This case also shows very clearly the extent of possible movement while

Figures 5A and 5B: A comparison of the profile before and after the treatment: The good proportion of the visual profile becomes apparent

Figures 7A-7C: The cause of the increased overjet here is primarily the pronounced Curves of Spee in the upper and lower jaw. During the leveling process, a loss of anchorage can be triggered, which can be intercepted by the BMT™

Figure 6: Despite great sagittal overjet and the need for an appropriate treatment, some Class II cases are less likely to be caused by a skeletal component

This enabled a stable occlusion

wearing the device. A lateral cephalogram can reveal that a bite gap may be almost completely avoided with the use of an intermaxillary elastic band (Figures 4A and 4B). At the same time, it is also possible to achieve an excellent profile improvement through the use of the BMT as illustrated in the reference profile photos (Figures 5A and 5B).

Greatly enlarged, heavily protrusive sagittal incisors (overjet) An enlarged overjet does not have to be caused by a pronounced skeletal Class II feature (Figure 6). In the case of this 13-year-old boy, an overjet of 7 mm is present at the start of treatment. However, this was mainly caused by the pronounced Curves of Spee in the upper and lower jaw, and less so by a heavy skeletal component (Figure 7). The goal of the treatment here was to reduce the overjet significantly in 14 Orthodontic practice

order to stabilize both sides of the Class I molar and canine region, and to regulate the overbite. To this end, a non-extraction treatment. was carried out with a multi-bracket appliance using the Straight Wire system.

Additionally, a transpalatal arch was used to control the upper molars. For a precise leveling, .014 NiTi, .018 NiTi, and .018 steel archwires were used on both jaws.

Then the BMT was used on both sides and treated further with the 19 x 25 NiTi, 17 x 25 steel arches (Figure 8). Following that, remaining gaps were closed using the 19 x 25 steel archwire, and final corrections applied. The BMT was then removed after a period of 6 months along with the rest of the MB device, which means that the apparatus was worn for a total of 13 months (Figures 9 and 10A-10C). If during that time, the equipment caused a minimal posterior open bite, this can easily be optimized by

natural settling during the retention phase.

Those who prefer to actively achieve this may choose a positioner, if necessary.

Correction of a unilateral Class II This case of a 12 year-old girl illustrates the correction of a unilateral Class II, which was primarily caused by a rotation of the mandible. While the center line in the upper jaw proceeded along the facial axis, the mandibular midline was, however, shifted to the left (Figure 11). Accordingly, an Angle Class I was present in the right molars region, as well as a ½ Class II to the left.

The lower facial height was low, and there was a deep bite tendency. The treatment was carried out without extractions with a fixed appliance using the Straight Wire technique. After the leveling phase (from .018 steel arch in the 22nd slot system), the BMT was used on the left side to achieve a center Volume 6 Number 3

CASE STUDY correction by a unilateral post-development of the mandible (Figures 12A-12C). At the same time, it is important to pay attention to the proper arch coordination of the upper and lower jaw, as well as to take into account vertical components in the unilateral Class II therapy. The treatment time was 18 months using the multi-bracket appliance. The BMT was used after 6 months and removed again after 15 months, which meant a total wearing period of 9 months.

The therapy targets — the middle and neutroclusion correction — could therefore be successfully implemented in an acceptable time frame (Figures 13A-13C).

Figures 12A-12C: To correct the asymmetry, the BMT™ was used only on the left side and activated with a slight correction

Figures 13A-13C:The center and a bilateral Class I occlusion were successfully set and achieved the therapeutic goal

Class II therapy in adults If, in the absence of growth, the development of a Class II occurs, in the past, there was only the possibility to perform orthognathic surgery or to camouflage extraction therapy.

Nowadays, however, it is also known that a fixed Class II device can be used successfully in these cases. Surgery was not an option for the 28-year-old female patient presented here. Due to her profile, an extraction treatment did not result in a satisfactory outcome either (Figure 14). Hence, the treatment of choice was a multi-bracket treatment with less esthetically pleasing ceramic brackets and a barely visible apparatus for correcting the skeletally caused defect of the mandible (Figures 15A and 15B). The Baxmann Mini Telescope was used directly together with the MB appliance. The upper molars were supported by means of transpalatal arches.

It has now worked without complications with the standard arch sequence: .014 NiTi, .018 NiTi, .018 steel, 19 x 25 NiTi, 17 x 25, and 19 x 25 steel (Figures 16A-16C). The BMT (17 x 25 steel) was left in place for up to 12 months, and during each follow-up visit (every 6 weeks), the stability of the jaw position was checked. It was a simple and practical way to make sure that the new jaw position was set not only temporarily, but could actually be stabilized in the long term.

The active treatment was completed after a total period of 15 months (Figures 17A-17C).

Following that, the retention was performed with Hawley retainers and nightly Class II rubber bands. After another 3 months, the elastics were eliminated entirely, and the wearing time reduced from 14 hours a day to just nighttime. Further retention protocol proceeds individually after that.

Summary The BMT is a new apparatus that fits into the line of rigid, fixed Class II equipment. In this article, it was tested in practical cases 16 Orthodontic practice

Figure 14: Surgery, extraction therapy, or BMT™. In moderately severe Class II cases, fixed Class II appliances are certainly a very good alternative

and successfully used in various orthodontic situations. The BMT was used on just one side or used on both sides depending on the starting position. It is therefore particularly pleasing to the practitioner that the corresponding components are identical on the right and left, and that the attachment of the apparatus is performed identically to conventional molar bands in all four quadrants. Consequently, the use of the BMT does not require special skills or expensive laboratory steps. The range of its application is very broad thanks to the exclusive attachment in the molar region. As a result, the Baxmann Mini Telescope can be used early on, from treating children, all the way to adult therapy. Especially in the case of esthetically demanding patients, the small dimension

of the apparatus can be considered as “invisible,” which is very appropriate. Not only is it barely visible with the mouth open with the BMT, the pronounced protrusion of the lower lip, which is often observed when using larger equipment, does not occur.

Those who have tried using the BMT have come to love the ease and reliability of the apparatus. Finally, it should be noted that the BMT has proven itself to be simple to use, in addition to achieving a high level of comfort in wear and very pleasing esthetics.

It also has clinically proven effectiveness as an interesting and practical alternative within the family of Class II equipment.

ORTHODONTIST’S VIEWPOINT

Take only CBCTs on these types of orthodontic cases Dr. Jack Fisher discusses 10 reasons to use 3D imaging

T

he specialty of orthodontics has of recent years had an influx of technology within the industry. Intraoral scanners are now being used in many practices and residency programs. We are told that this technology will eliminate alginate impressions. We are told that 3D printers will replace plaster models and perhaps print out our brackets.

We are told that aligners are now returned to the practice faster with this technology. l am still not sure how this new technology really benefits the care of our patients within the specialty of orthodontics.

The advent of 3D imaging technology has also recently come to the forefront within the orthodontic specialty. Many have stated that this type of imaging does not significantly benefit patients or aid in the diagnoses and treatment planning of their patients. The amount of radiation from older machines certainly was a concern. The recent introduction to the market of a 3D machine by Planmeca is advertised to deliver a dose of 14 ms with an Ultra Low Dose™ setting.This is a full scan taken at a .06 voxel size. If this proves to be the true dose of radiation received by this machine, then the argument for too much radiation is now not an issue any longer.

Many have argued that as orthodontists we are not trained to read this type of data of DICOM images. We are, or should be, trained within our residency training to read cephs, PAs, and submental vertex radiographs. The 3D scan of a typical patient is comprised of approximately between 450 and 600 DICOM images that are represented in the three planes of space: sagittal, coronal, and the axial planes. These are the same three planes of space we are trained to read — just many of them on the same patient.

Jack Fisher, DMD, brings 28 years of experience to his practice.

He attended the University of Louisville School of Dentistry and then continued to his residency at the Medical College of Georgia where he received a certificate in orthodontics. He is honored to serve and teach residents at New York University, University of Louisville, and Vanderbilt orthodontic Post-Graduate Residency Programs. He enjoys teaching orthodontists worldwide about various orthodontic topics and has lectured as far away as Australia. Dr. Fisher is an inventor of various orthodontic products and holds several U.S. Patents. His practice, Artistic Smiles Orthodontics, is based in Memphis, Tennessee.

So let’s look at the only reasons to scan a patient seeking orthodontic treatment.

1. Many have advocated that the use of 3D imaging is certainly useful in treating patients with impacted maxillary canines.

This is certainly true. However, only 1% to 2% of the population has impacted canines.

Research shows that within the population of most orthodontic practices, 5% of the practice’s patients seeking treatment have impacted canines. If this is the main reason for taking DICOM images on patients, then these images should be outsourced. The cost of purchasing a 3D machine for 5% of the office’s patients does not make financial sense. A two-dimensional pan or ceph does not adequately image the impacted teeth for not only surgical planning but also the mechanics needed to move these teeth into alignment. It has been reported that 62% of palatally impacted canines are touching the roots of laterals and centrals. This is information that 3D imaging illustrates. This could often change the mechanics needed to properly position the canines without damaging the roots of adjacent teeth. However, the 3D imaging of impacted teeth certainly is advantageous to the orthodontist or oral surgeon who will surgically expose the nonerupted teeth. This is illustrated in Figures 1A, 1B, and 1C. The clinician can readily

Figures 1B-1C

see the benefits to the patient for using the 3D imaging technology for the treatment of impacted teeth.

2. Any patient needing orthognathic surgery should receive a scan.

The scan is certainly more diagnostic in all three planes of space than a two-dimensional cephalometric image. Many oral surgeons can now use this scan to send to medical modeling companies for the construction of the splints used during the surgery. Not to mention the three planes of spaces gives the orthodontist a better perspective of the problem list prior to treatment planning and pre-surgery orthodontics. The models that are either acquired by a scan or with plaster models are incorporated in the patient’s 3D scan. The medical modeling companies can then do the surgery digitally and use the 3D models to make the surgical splints. These DICOM images give the orthodontist a more accurate visual treatment objective prior to treatment as also the digital surgery gives the oral surgeon a thorough perspective of pre-surgical planning. The patient illustrated in Figure 2 shows different types of images that can be generated from a set of DICOM images. With an exposure of only 14 microsieverts, the orthodontist can attain a pan, a ceph, and many different types of 3D images from the three simple planes of space to 3D images. Final records were acquired Volume 6 Number 3

ORTHODONTIST’S VIEWPOINT

Figure 2

Figures 3A1-3A3

with an additional scan totally another 14 microsieverts.

3. Any patients needing their anterior teeth moved in the sagittal plane.

A traditional cephalometric image is a composite of the cephalic. The true amount of bone either anterior or posterior to the roots of these teeth is not visualized in the traditional cephalometric or panoramic images. When there is not adequate bone to move the roots of teeth into a space, the clinician has only two options: Either have bone placed by a periodontist or maintain the patient’s inclination of these incisors. The use of Class II correctors has grown tremendously in the past few years. These devices often flare the lower incisors as much as 10 degrees. Fenestrations and the lack of bone support results. Is this a stable environment for incisors? We also often recline the upper incisors. Is the alveolus wide enough in the sagittal plane to accommodate the roots of the teeth? Now with the use of skeletal anchorage devices, we are more likely to exceed the patient’s biological limit. Again, a traditional ceph or pan does not show the true anatomy in this plane. The axial plane is also available with a 3D scan. This plan also gives the clinician a more thorough understanding of the availability of bone to move the incisors. Figure 3A illustrates a patient seeking treatment for a severe overjet and overbite. The pan and ceph do not reveal the enough information to properly diagnose this case. After imaging in the sagital view with a CBCT, the clinician can readily see Volume 6 Number 3

Figures 3B1-3B3

Figures 4A1-4A2

there is a lack of bone to move the upper incisor. The patient in Figure 3B illustrates a patient with a lack of bone around the lower incisors. Again, the traditional pan and ceph do not give enough information to properly diagnose and treat this patient.

4. Any patient who will have a temporary skeletal anchorage device (TSAD) placed.

Most clinicians that have become proficient and confident with the placement and use of TSADs place them on approximately 23% of the case treatments planned in their practices. When evaluating the placement

site in all three planes of space, the clinician can become very exact with locating structures that should be avoided. More TSADs are being placed in the infrazygomatic area.

A 3D image is the best way to locate the best area of placement for stability in this area.

See Figure 4A1 and note the thickness of the bone in the infrazygomatic crest. Compare the thickness of the bone in Figure 4A2.

The bone in this figure demonstrates bone that is too thin for placement of the TSADs. More TSADs are being placed in to palatal approach. TSADs placed in the premaxilla are an area of placement that is vitally important to visualize the anatomy in this area.

Orthodontic practice 21

ORTHODONTIST’S VIEWPOINT

Figures 4B1-4B3

Figures 5A1-5A4

Figures 5B1-5B4

The clinician should consider the thickness of bone in this area to avoid the tips of the TSADs from penetrating the nasal cavity and to avoid the roots of the teeth in this area. See Figures 4B1, 4B2, and 4B3. When skillfully placed in adequate bone, the use of TSADs certainly allows orthodontists to treat their patients more consistently and predictably. The use of 3D imaging aids the clinician in the placement and use of the TSADs.

Figures 6A-6B

5. Any case that needs expansion of the maxilla.

Three-dimensional imaging in these cases allows the orthodontist to determine if a crossbite is skeletal or dental. The clinician can readily determine if the molars are inclined in a crossbite, or if the entire maxilla is constricted. This, in turn, then can determine what forces are desirable to correct the crossbite. The 3D images also allow 22 Orthodontic practice

the clinician to evaluate the amount of bone around the roots of the teeth that are to be expanded. This also can aid the orthodontist in the type of forces to be utilized. Maybe bone augmentation is indicated in certain areas, so the roots are not once again fenestrated through the cortical bone creating a less stable environment (see Figure 5). Figure 5A1 illustrates a maxilla that is constricted due to a narrow maxilla. Figure 5A2 illustrates the maxilla after expansion. Figure 5B1 illustrates a molar being tipped lingually. Thus a unilateral crossbite appliance was utilized.

6. Any case that possibly will be receiving a permanent implant.

The clinician placing the implants will need to evaluate the bone to determine how much area is needed between the teeth and to evaluate the thickness of the bone receiving the implant. Permanent implants are also employed to be used as anchorage during orthodontic treatment. The evaluation of the bone in all three planes of space is important for the placement and stability of permanent implants. Figures 6A and 6B illustrate an example of implant placement.

ORTHODONTIST’S VIEWPOINT

Figures 7A-7C

7. Any patient suspected of having a compromised airway.

Granted, this is not known until the patient is scanned. However, if there is an inadequate airway, the location of the constriction could determine the type of treatment the patient receives. For example, it could change the treatment plan from a camouflaged treatment to a mandibular advancement. A traditional ceph is not adequate in determining the size of an airway. The subject of imaging and treating compromised airway patients is experiencing more advancements in dentistry than any other subject. It is this clinician’s opinion that the orthodontic specialist should be the most qualified clinician to aid in the treatment of these types of patients.

These patients deserve a multidisciplinary approach, perhaps more than any other type patient we see in our practices. DICOM images are vitally important for the proper diagnosis and treatment of these individuals.

Figures 7A and 7B illustrate this.

This patient had a chief complaint of overjet. She could be treated with the retraction of the upper anteriors. After further imaging, it was decided that a mandibular advancement would best serve her. Also, note the osteophyte on C1 that is constricting the airway. This is not a common occurrence.

This osteophyte needs to be removed. So

the DICOM images changed our treatment plan. Figure 7C illustrates another patient seeking treatment after surgical relapse.

This patient will need to be treated with surgery again. Note the restricted airway at the hypopharynx. This must be treated prior to the retreatment of this case. Also, note the upper centrals have been torqued through the lingual cortical bone. These two problems are not viewed with conventional 2D images.

8. Any patient with a temporomandibular joint (TMJ) disorder.

Once again, this is not always known prior to the scan. Internal joint disorders are

often found during the manipulation of the DICOM images. For example, the etiology of an open bite in a female teenager may be due to idiopathic condylar resorption.

Is it not best to know this on the front end of orthodontic treatment? Many joint conditions are asymptomatic for patients seeking routine orthodontic treatment.

Most joint problems are not visualized on the routine pan and cephs. Being able to image the TMJ in all three planes of space is imperative in patients receiving comprehensive orthodontic treatment. Figure 8A illustrates a 14-year-old female with obvious challenges of her condyles. She

happened to be asymptomatic. However, it is better to have the information before orthodontic treatment so the patient and the parent are fully informed of this condition. Figure 8B illustrates a bifid condyle that is also asymptomatic. Neither of these two conditions was visualized on the traditional pan and ceph.

9. Any patient having supernumerary teeth that are not imaged in a routine pan.

Once again, this is not known until the scan is taken and read by the clinician. I personally have found supernumerary teeth that were not in the trough of the routine pan. We have found mesiodens that were not visualized on the pan. Figures 9A and 9B illustrate a patient for whom the mesiodens was not obvious on the pan or the ceph.

However, the extra tooth is imaged on the sagittal view of the scan (Figure 9C).

The etiology of the reclined centrals is the mesiodens. If the scan had not been taken, this may have been missed.

10. Any patient having pathology that is not imaged on the routine 2D radiographs traditionally taken on the orthodontic patient.

Again, we are not aware of these conditions that may exist prior to making a decision of what kind of images we need on 26 Orthodontic practice

a patient presenting for orthodontic treatment. Figure 10 illustrates just a few of the conditions that were discovered on the 3D images but were not evident on the traditional 2D images. The first patient in Figure 10A shows a patient in the axial view where C1 is rotated to the patient’s left. This is also restricting the airway. Figure 10B illustrates a patient who was scheduled for a maxillary osteotomy. The maxillary left sinus is not present. This is reported to be a condition that is present in 1:100,000 people. I believe this condition to be more frequent, having seen this condition in three patients in the last 3 years. Figure 10C illustrates in all three planes of space an enlarged pituitary gland. This patient’s pituitary gland had to be removed. Figure 10D shows a patient with a large traumatic bone cyst. This was not readily evident on the pan because the lesion is so large. This was biopsied and was determined to be a traumatic bone cyst. Figure 10E illustrates a large nasal bone cyst. We have discovered several smaller ones over the past 3 years that were not evident on a pan. This one, however, was evident on the pan. The enlarged pineal gland was not demonstrated on the pan or ceph but is evident on this image in the sagittal plane of space. Figure 10F1 illustrates a osteophyte on C1 of a 26-yearold female. Figure 10F2 shows a different view. This patient was referred for a sleep

study and was diagnosed with severe sleep apnea. The osteophyte has been removed.

We have illustrated only a few of the conditions we have discovered.

The routine use of DICOM imaging in the specialty of orthodontics may be approaching. We actually just used the term “routine.” This raises a question.

We as a specialty do not get to determine what is a standard of care. This is determined by the courts. Any of the 10 reasons discussed in this article that were not imaged thoroughly and perceived as less than adequate treatment delivered could be brought into question in a judicial environment. Yes, we are liable for all the data obtained with a scan. We are also liable for the data we do not care to image when more and more clinicians are using routine DICOM images. How and why did pans and cephs become routinely utilized in the specialty? We are specialists. We should educate ourselves accordingly and use the technology available to treat the patients who trust us with their care. If it is in fact a truth that the newer machines are delivering the dosages of radiation as advertised, there is no longer an excuse to not learn and educate ourselves to better treat our patients.

Patient YO Patient YO, a 40-year-old female, presented with a Class 2 subdivision right malocclusion with an upper dental midline shift of about 5 mm to the right of her facial midline. She showed no indication of a skeletal asymmetry. Both the upper and lower arches showed severe crowding. In addition, the patient presented with a missing upper left second molar and impacted lower third molars. The upper third molars were erupted (Figure 1).

The facial midline was selected as the treatment midline, and the first bicuspids were planned for extraction to correct both the crowding and the midline and treated to a Class 1 occlusion. In addition, it was decided to close the upper left second molar extraction site by protracting the upper left third molar. It was also recommended that the patient have the remaining third molars extracted. The Virtual Diagnostic Simulation

(VDS) is shown in Figure 2. Also, note with the simulation, it was possible to anticipate the potential risk of black triangles appearing post orthodontic treatment (Figure 2B).

Superimposition of the VDS against the VDM is planned, and the tooth displacements are shown Figures 2C-2F. Treatment was initiated by placing a fixed upper transpalatal arch with a distal extension arm on the left side to which elastic was attached to a lingual button placed on the buccal to move the upper third molar lingually, protract it, and partially derotate it (Figures 3A and 3J). Extraction of the lower first bicuspids was performed, and 3 weeks post extraction, separate canine retraction with ligature rope ties was initiated in the lower arch (Figure 3B).

The upper first bicuspids were extracted, and 8 weeks from the start of treatment, separate upper canine retraction was initiated with a stainless steel ligature rope tie (Figure 3C).

At the 12-week appointment, the upper arch was bonded with Tomy “CLIPPY-C” (In-Ovation® C, Dentsply GAC International bracket) with a slot width of .0180", and a .016" CuNiTi AF 35ºC upper alignment archwire was placed. Also, an open coil spring was inserted between the right upper canine and right central incisor to open space for the lingually blocked upper right lateral incisor and also shift the upper dental midline to the patient’s left (Figure 3D). Four months into treatment, the upper right lateral was bonded and engaged into the upper archwire, which remained unchanged (Figure 3E).

In month 5, all the space on the upper right side was closed. The space closed asymmetrically (more on the right side than the left), and both the buccal segments showed signs of tipping. Also, protraction and lingual movement of the upper right third molar proceeded well. At this time, the lower arch was bonded, and a lower .016" CuNiTi AF 35ºC was engaged to begin the alignment of the lower anteriors. The lower right lateral was not bonded as it had a severe rotation.

Its bonding was deferred to the next appointment when sufficient space was available to derotate it. Bite turbos on the lower molars were placed to prop the bite open so that the upper right lateral could be brought out labially. Also, the distal extension arm on the transpalatal arch was cut while the arch was kept in place (Figure 3F). One month later (month 6), the lower right central was bonded and engaged with the archwire. The upper right third molar was also bonded and engaged with a .016" CuNiTi AF 35ºC archwire (Figure 3G). At the next appointment (month 7), the round archwires were replaced with .017" x .025" CuNiTi AF 27ºC archwires to achieve uprighting of the buccal segments (images not shown). The patient was seen in month 9, and substantial leveling of the tipped buccal segments had occurred by now. As a result, some spacing had opened distal to the canines. The upper left seven extraction site was completely closed. At this time, power arms were crimped on the archwire in both the upper and lower arches, and space closure initiated with power chain (Figure 3H). The patient was seen a month later (month 10).The upper archwire to the upper left 6 was cut since the patient had lost a bracket on the third molar. Note that space mesial to this tooth opened up (Figure 3I). At month 11, the patient was scanned (Figure 4).

The total treatment time was 15.5 months.

The VDS versus VFM is shown in Figure 8A. Most of the treatment objectives were met. The upper buccal segment anchorage was held according to plan; however, the lower was not slipped enough resulting in

a slight Class 2 occlusion. Complementing space closure with some Class 2 elastic wear to encourage lower molar protraction during treatment may have averted this situation. Also, slight spacing remained between the upper central incisors and the upper right canine. It is planned to close this with a Hawley’s appliance. This will require removing the upper 3-3 fixed retainer. Once the space is closed, permanent retention

will extend to include the 5-5 segment to minimize any potential of space reopening since there is a high likelihood for this to recur. Note that some space also opened mesial to the upper left third molar. It is planned to leave this space open. Lastly, it should be noted that the black triangles as predicted in the VDS at the beginning of treatment did manifest themselves in vivo (Figure 8B).

Patient TE Patient TE, a 22-year-old female presented with a Class 2 subdivision left malocclusion with a bimaxillary dental protrusion, a steep mandibular plane angle, a long lower facial height, and a skeletal mandibular asymmetry. Severe dentoalveolar compensations were present in the lower anteriors, which had tipped to the patient’s right causing the lower midline to deviate from the upper dental and facial midline by about 3 mm. Also, there was a slight clockwise cant in the upper esthetic occlusal plane. There was moderate crowding in the upper and lower arches. The patient also had a large asymmetric anterior overjet (Figure 9).

The facial midline was chosen as the treatment midline. The maxillary functional occlusal plane was chosen as the treatment occlusal plane, and maximum retraction of the incisors was planned in order to reduce the bimaxillary protrusion. The lower archwidth at the first molar level was chosen for the limits of the archwidth. The treatment goal was to treat to a Class 1 occlusion. An asymmetric extraction pattern was planned. The upper first and the lower right first bicuspid and the lower left second bicuspid were extracted.

36 Orthodontic practice

The patient was also recommended to have all her third molars extracted. However, she chose only to have the lowers extracted. The Virtual Diagnostic Simulation for patient TE is shown in (Figure 10).

The upper and lower arches were bonded with Sankin Clear brackets (Sankin Inc., Dentsply International, Tokyo, Japan) with slot width 0.0220". Four tads were placed to enable differential anchorage control. The upper left TAD was placed a little higher in order to enable the correct ion of the clockwise cant of the upper esthetic occlusal plane (Figure 11A). A .016" CuNiTi AF 35ºC was used as an initial archwire for both the upper and lower arches. Space closure was initiated on this archwire by sliding mechanics using a power chain.

An upper transpalatal arch was placed to maintain intermolar width. Six weeks into treatment, the power chain was replaced with superelastic NiTi coil springs to facilitate space closure on .016" stainless steel archwires (figure not shown). By the 4th month, the lower incisors had uprighted, and separate canine retraction in both arches was almost 50% complete (Figure 11B). En masse upper incisor retraction was begun at

the 8th month with .016" x .022" stainless steel L-shaped closing loops. In the lower arch, anterior spacing was consolidated with a power chain on a .016" stainless steel archwire. At this time, the upper transpalatal arch was also removed (Figure 11C). All upper and lower space was closed by month 12.

The upper closing arch was removed and replaced by a round 016" superelastic NiTi AF 27ºC, and the lower archwire was also replaced with a similar archwire. These wires were engaged just to hold the correction of the occlusion until the therapeutic scan was taken (Figure 11D).

The therapeutic scan was taken 1 month later (Figure 12). At this stage in treatment, the buccal segments were Class 2, and a midline discrepancy was apparent. A Virtual Target Setup and a .019" x .025" CuNiTi AF 35ºC suresmile precision archwire were designed (Figure 13).

The precision archwire was inserted in both the upper and lower arches 6 weeks post therapeutic scan (Figure 14A). The patient was asked to wear bilateral Class 2 elastics and double up on the left side.

When considering the treatment of midline discrepancies, it is important to recognize the etiology of the malocclusion, the patient’s wants, and the potential limitations of orthodontic treatment in correcting the midline. Furthermore, one needs to recognize that in patients with skeletal midline discrepancies treated orthodontically, dentoalveolar compensations may need to be maintained or exaggerated. These may manifest as a cant in the esthetic occlusal plane. In addition, it is important to recognize that an upper midline up to 4 mm off the facial does not appear to impact the layperson’s impression regarding smile esthetics.7 The purpose of this series of articles has been to demonstrate that successful outcomes are driven by the ability of a doctor to plan care based upon an in-depth diagnosis and design therapeutics that are consistent with the treatment objectives.

In addition, appropriate care surveillance through the patient’s care cycle is a vital ingredient to ensure planned outcomes.

Patients do need to be encouraged to participate in their care. This increases the likelihood of successful care. Technology such as suresmile is designed not to dominate the clinician’s judgment but to serve his needs to support the delivery of reliable care.

Future articles will expand on the application of suresmile in managing patients requiring interprofessional care. OP

PROPELLING ORTHODONTICS

The impact of integrating Acceleration Technology into your practice Dr. Lou Shuman discusses the benefits of Ortho Acceleration

O

rthodontic Acceleration is on the threshold of forever changing how orthodontics is provided. The benefits of acceleration far outweigh any perceived barriers, and soon the consumer population will demand it as part of standard orthodontic care, as was the case with Invisalign®. The clinical literature demonstrating the efficacy of micro-osteoperforation abounds (for Propel clinical articles and case studies go to www.propelorthodontics.com), as well as studies that show patients are interested in accelerated treatment and willing to pay extra for reduced treatment time.1 This month’s column moves in a different direction — first, a personal opinion on Propel technology and then practice management tools that can accelerate practice growth in addition to clinical acceleration.

To start, what sets Propel apart as the most viable Accelerated Orthodontic option?

• It is doctor controlled and NOT patient controlled.

• That means you have a significantly better chance of more predictable results and promised time outcomes.

• It has the ability to target difficult movements and treat just one arch, which is critical for those with adult patients.

• As an orthodontist specializing in adults for many years, lower adult onset crowding was the single most common case I treated. After reviewing other orthodontic acceleration systems, I have difficulty accepting

technologies that impact the entire dentition when the treatment plan calls for treating only one arch.

• Many times, it only takes one visit or application to provide 3-6 months of acceleration. This is far more efficient than relying on patients to be compliant on a daily basis and, in many cases, while also attempting to be compliant with aligner wear simultaneously.

• It is by far the most cost-effective treatment available today2 with pricing as low as $100 per patient.

Similar to all Acceleration Technologies, your gross production per hour can easily double.

• Your annual production is significantly increased as you have more open chair time for new patients by finishing cases so much faster.

Current perception of optimal lip protrusion among African American laypersons Drs. Moshood B. Martins, Daniel Rinchuse, Lauren S. Busch, Anthony L. Farrow, and Thomas Zullo discuss the subtle differences in people’s esthetic preferences Abstract Objective: Patients of different races, genders, and generations have subtle differences in their esthetic preferences. The objective of this pilot study was to evaluate the preferred amount of facial protrusion among 21st-century African American laypersons.

Methods: Profile photographs of a male and female subject were digitally altered using Adobe Photoshop to create three different profile types by manipulating the amount of lip protrusion in 3-mm increments.

Lip protrusion amount was measured from glabella perpendicular to the outermost part of the upper and lower lip. Each photograph was rated based on level of attractiveness by 40 African American laypersons.

Results: The profiles most preferred by the African American laypersons were profiles with natural lip position (0.0 mm-3.0 mm) and mild protrusion (3.1 mm-6.0 mm).There was no difference in preference between natural lip position (0.0 mm-3.0 mm) and mild protrusion (3.1 mm-6.0 mm).

The laypersons in Farrow’s study found mild protrusion to be the most favorable profile. In this pilot study, the layperson raters did not distinguish between mildly protrusive profiles and profiles with natural lip position. Results from this pilot study suggest that African American laypersons prefer different levels of lip protrusion than they did 20 years ago.

Introduction Upon initial examination and consultation with a patient, the astute orthodontist envisions the patient’s optimal facial esthetic end result.1 Facial esthetics influence an individual’s ability to integrate with society as well as his/her level of self-esteem and psychological well-being.2,3 Today’s orthodontic patients are becoming increasingly aware of the significance of a beautiful smile and overall facial beauty.2,4 In order to conceptualize the patient’s optimal end result, the practitioner should interview the patient.5-10 The patient has his/her own generational, racial, and cultural perceptions of beauty.

During treatment planning, the orthodontist may need to set aside his/her own generational, racial, and cultural biases of beauty and treat to the patient’s preferences as long as it does no harm.4 Orthodontists must consider the role race plays in soft tissue profile preferences.

Traditionally, African American patients with bimaxillary protrusion and dentoalveolar flaring of the upper and lower teeth would Volume 6 Number 3

African American soft tissue measurements between patients to be greater than in Caucasian patients.15 Farrow, et al.,11 studied African American protrusion in 1993 and found that African Americans prefer slight bimaxillary protrusion over straight profiles. Farrow, et al.’s11 study also found African Americans do not find moderate to severe bimaxillary protrusion as attractive as mild bimaxillary protrusion.

Materials and methods This pilot study aims to add more information regarding African American esthetic preferences — specifically the facial profile — by comparing this study’s results to findings published by Farrow, et al., in 1993. Prior to the collection of any data, approval for this study was obtained from Seton Hill University’s Institutional Review Board.

The design of this pilot study was modeled after the study conducted by Farrow, et al.,11 which was published in 1993. This study differs from Farrow, et al.’s in three ways: 1. The scope was narrower since Farrow, et al., had layperson, orthodontist, and general dentist raters, whereas this study only had layperson raters.

2. More modern technology was used to digitally alter target person photographs.

A professional graphic designer used Adobe Photoshop (Adobe Systems, San Jose, California) to manipulate lip protrusion and blend skin tone, providing a more natural appearance than Farrow, et al.’s black-and-white photos.

3. Era — Farrow, et al.’s study was conducted 21 years earlier.

Selection of the target persons Two average level-of-attractiveness African American target persons were selected by one of the authors (MM). The author who selected the target persons (MM) is African American. Target person selection was based on the following inclusion criteria: 1. African American between the ages of 18 and 40 2. No obvious facial abnormalities The target persons were asked to remove all facial jewelry (nose ring, earrings, necklaces, and glasses). Upon each target person submitting a signed consent-toparticipate form, they were asked to identify their race and age.

Lateral photographs of the male and female targets were taken against a whitecolored background using a Pentax Optio WG-1 camera. The protocol of a white background follows the standard of the American Board of Orthodontics photographic procedures. A fixed distance of 6 feet between the target person and the camera maintained consistency with each photograph taken.

Digital photographs of the target persons were sent in JPEG (Joint Photographic Expert Group) format to a professional graphic designer for alterations of the maxillary and mandibular lips. This study used color profile photographs for the evaluation, P2

have been treatment planned for extraction of four first premolars, producing a more straight facial profile.11,12 Possibly , this treatment plan may have led to disappointing results for an African American who would have preferred to maintain his/her protrusive profile.

African Americans’ perception of beauty has been briefly characterized in the orthodontic literature, but as a whole the literature is limited.11 African American anatomical features lend them to having more protrusion and thicker lips than their Caucasian counterparts.11 In a study using 100 different photographs of African American soft tissue profiles, Sushner demonstrated that Ricketts’ esthetic plane, Holdaway’s “H line,” and Steiner’s “S line” were not applicable to African Americans because of their naturally fuller profiles.13 Further, cephalometric norms for African Americans also reflect more protrusive soft tissue profiles than Caucasians. While normative values of African American protrusion may remain relatively constant over time, the practitioner must constantly weigh what their African American patients consider to be the minimum and maximum threshold of esthetic facial protrusion.10,14 In a cephalometric study deriving soft tissue norms from 82 African American adolescents with Class I occlusions and well-balanced faces, Dr. Larry White concluded that the absence of strain in and around the lips when the patient is in centric occlusion translates into favorable soft tissue contour irrespective of lip thickness. He also found the range of acceptable

Lip protrusion was measured in the same manner used by Farrow, et al.11 The glabella perpendicular line, which is a line from the soft tissue glabella drawn perpendicularly to Frankfort horizontal was measured to the most prominent point on the upper and lower lip. The target persons’ profiles each began in the natural (N) category, with the outermost portion of the lips measuring 0.0 mm-3.0 mm from glabella perpendicular. From the target photo’s natural (N) position, the lips were digitally advanced horizontally using Adobe Photoshop (Adobe Systems, San Jose, California) in 3-mm increments. Lips in the range of 0.0 mm-3.0 mm of the line glabella perpendicular were classified as normal (N).

Lip protrusion from 3.1 mm-6.0 mm was classified as protrusive one (P1). Lips that measured 6.1 mm-9.0 mm from glabella perpendicular were classified as protrusive two (P2). Finally, lips that measured 9.1 mm -12.0 mm from glabella perpendicular were classified as protrusive three (P3) (Figures 1A-1D and 2A-2D).

Selection of the raters Fifty African American laypersons were recruited from a Bible study group in Washington, D.C., to evaluate four profile photos of the two target persons. Raters had to meet the following inclusion criteria in order to qualify to participate in the study: 1. African American male or female between the ages of 25-40 2. Identify themselves as African American 3. No experience in the field of dentistry From the group, 40 individuals (24 males and 16 females) met the inclusion criteria and agreed to participate in the study.

Following signed consents, a folder was handed to each rater with detailed instructions. Raters were asked to report their age, race, and sex. Raters were given a two-page composite of eight randomly manipulated photographs of the male and female African American target persons to rank. The first page displayed the male target with four different profiles. (Figures 1A-1D) The second page displayed the female target person with four different profiles. (Figures 2A-2D) The raters were asked to rank each composite from one through four based on level of attractiveness.

One was labeled as most unattractive, two unattractive, three second-most attractive, and four most attractive. The raters were told to assign only one number per profile. Rating 50 Orthodontic practice

was requested in this particular manner to eliminate any mutual rating of any photographs. All data was collected and tabulated for statistical evaluation.

Results Analysis of variance showed that the only statistically significant difference was for the level of lip protrusion (F = 47.69, P< 0.0004). There were no statistically significant interaction effects for target photo gender versus rater gender (F = 0.661, P = 0.421) or gender of target photo versus lip protrusion (F = 1.187, P< 0.318).

Pairwise comparison demonstrated no differences between the natural lip position (0.0 mm-3.0 mm) and protrusion one (3.1 mm-6.0 mm). The natural lip protrusion (0.0 mm-3.0 mm) is significantly more attractive than both protrusion two (6.1-9.0 mm) and protrusion three (9.1 mm -12.0 mm).

Pairwise comparisons also revealed that protrusion one (3.1 mm-6.0 mm) was viewed as more attractive than protrusion two (6.1 mm-9.0 mm) and protrusion three (9.1 mm-12.0 mm). Additionally, protrusion two (6.1 mm-9.0 mm) was viewed as significantly more attractive than protrusion three (9.1 mm-12.0 mm) (Tables 1 and 2). However, four raters found protrusion three to be most attractive, and 10 raters found protrusion two to be the most attractive.

Discussion Darwin once wrote17: “It is certainly not true that there is in the mind of man any

universal standard of beauty with respect to the human body. … The men of each race prefer what they are accustomed to behold.”

Race plays one of the most central roles in patient esthetic preferences.

However, orthodontic literature on esthetics is heavily Caucasian-centered with fewer studies on minority races. Therefore, when treating minority populations such as African Americans, the orthodontist may need to better familiarize himself/herself with the African American esthetic literature, interview the patient regarding esthetics, and set aside his/her racial preferences in order to properly treatment plan the case.18-29 Racial esthetic preferences are dynamic.

Caucasian models from the early 1900s have straighter profiles than today’s super models, who have fuller profiles with more protrusive lips.18 African American optimal esthetics may be even more complex and changing than other races, as their makeup has so drastically changed in the past few decades, including a rise in the number of interracial children.30 Soft tissue profile preference among African American patients is further complicated by the fact that the term African American is an ambiguous term. The Census Bureau, for instance, identifies Black or African American according to the Office of Management and Budget’s definition as a “person having origins in any of the Black racial groups of Africa.”31 However, the Black category also includes respondents who report African American, Sub-Saharan Volume 6 Number 3

patients through communication and not assumption.32 The orthodontist can theoretically influence the soft tissue profile through various techniques and procedures such as lip reduction through extraction of the maxillary and mandibular first premolars and/or surgery in extremely protrusive patients.33-36 However, treatment to enhance soft tissue profile in one patient could potentially detract from the esthetics of the optimal soft tissue profile in another patient. A few raters preferred the most protrusive of profiles (P3 and P4). To achieve the best esthetic final outcome in these outlier raters, an orthodontist treating these types of individuals need to know that their protrusion threshold is higher by questioning them about their preferences about facial profiles.

Conclusions 1. Raters agreed upon the optimal level of lip protrusion (<6.1 mm from glabella

perpendicular) irrespective of target photo gender or rater gender.

2. African American laypersons raters found natural lip position and slight protrusion to be the most attractive profiles when compared to profiles of greater protrusion, and found no difference between these two profile variations.

3. The results of this pilot study have similar findings to those published by Farrow, et al., in 1993. However, raters in this pilot study found the straight profile to be more acceptable than the layperson raters in 1993. This pilot study is too small to reflect a trend; however, a larger sample may also show that in the past two decades, African Americans find less protrusion more acceptable/attractive than they did 20 years ago. Continued research is recommended to follow changes in esthetic preferences among the African American race. OP

African, and Afro-Caribbean entries. However, in the Census, an individual can report more than one race that refers to the multiple-race Black population. Those who identify with the Black alone category number is 38,929,319 while those who identify as combination is 1,330,180. African Americans combined make up 13.6% of the U.S. population. The total African American population alone or in combination was 15.4% in 2010. Moreover the African American in combination, or multiracial, has risen 75% from 2000-2010.31 Therefore, Blacks who reported themselves as combination grew at a faster rate than the Black alone population.

Because of the high number of Blacks who identify themselves as multiracial, the definition of African American esthetics may become more intertwined with other populations as more persons identify themselves as African Americans in combination. The black and white population was reported as the most frequent combination.31 Therefore, an orthodontist who is treating an African American may need to discuss with patients not only which race they identify with, but also if they identify themselves as being part of multiple races. Once an orthodontist determines which race patients are, he/she should ask which origin and then delve into that origin’s esthetics. Further, it is possible that a patient prefers a different race’s esthetic norm. This should also be discussed before treatment planning.

This pilot study highlights the fact that within a minority race, esthetic preferences may have changed from the early 1990s to now. Farrow, et al.’s study found African American laypersons to prefer a mildly protrusive profile, comparable to this study’s protrusive one category (P1). However, while Farrow, et al., raters found the straight profile to be less desirable than P1, in this study, African American laypersons did not distinguish between N and P1. The most attractive profiles were those in which the lips were <6.1 mm from glabella perpendicular.

Perhaps raters in this study are reflective of the more recent African American preferences, which likely come from a more mixed population than homogenous population.

One of the limitations of this pilot study is that it did not ask raters to specify whether or not they considered themselves 100% African American or of multiple races.

This pilot study is important to any orthodontic practitioner treating minority patients, particularly treating African American patients.

It demonstrates that an orthodontist must evaluate the protrusion threshold of his/her

Drs. George F. Schudy and Larry White explore acceleration of tooth movement

F

rom the beginning of the profession to the present time, orthodontists have been best known for aligning or straightening teeth. While our work involves much more — e.g., skeletal correction, TMJ harmony, bite correction, and so forth — it all begins with alignment. This is not only the phase for which we are best known, but alignment precedes the other phases. Frequently, our pivotal phases cannot be addressed properly before the alignment phase.

Ironically, this perfunctory step stands timewise between us and the more complex and time-consuming aspects of our treatment.

Any acceleration in this phase can be applied directly to our end goal of facilitating the other phases of treatment.

Literature — how fast do teeth move?

Jones, et al.,1 and O’Brien, et al.,2 in benchmark alignment studies in 1990 tested .014 NiTi and .015 multistrand stainless steel (S.S.), .016 Nitinol and Titanol, respectively.

Each wire was in place 35 days. Their average rates of tooth movement for their fastest alignment wires were 1.4 mm/month. Eighteen years later, Scott, et al.,3 were motivated to study Damon® self-ligating (SL) alignment versus synthesis conventional ligation (CL).

The rate of alignment was measured through the use of three wires: .014 NiTi, .014 x .025 NiTi, and .018 x .025 NiTi. Alignment continued until placement of a S.S. rectangular wire was possible. The rate of alignment was greatest during the use of the .014 NiTi — i.e., 3.6 mm/month for (CL) and 3.0 mm per month for (SL). Overall, however, the rate dropped significantly. Total rate was slightly less (243 days) with the conventional ligation (CL) and 253 days for Damon (SL). The (CL) had an alignment rate of .056 mm per day, and (SL) had an alignment rate of .047 mm

per day. For a 28-day month, this was a rate of 1.5 mm per month for (CL) and 1.3 mm per month for (SL).

Ong, et al.,4 did a similar study to compare initial alignment of Damon self-ligation (SL) versus conventional ligation — Victory series (CL). In this study, two wires, .014 NiTi and .014 x .025 NiTi, were left in place for a fixed time interval of 10 weeks each. As with Scott, et al., the conventional ligation (CL) alignment produced faster tooth alignment than selfligation (SL). In the mandible, the (CL) alignment (or reduction in irregularity) for the first 10 weeks was 8.4 mm of the initial 12.5 mm of irregularity and (SL) reduced irregularity 6.5 mm of 10.8 mm. This produced a rate of 3.3 mm/28-day month for (CL) and 2.6 mm/ month for (SL). In the maxilla during the first 10 weeks, the (CL) reduced at a rate of 2.7 mm/month and the (SL) was 2.6 mm/month.

During the second 10 weeks in the Ong, et al., study, the rates dropped as they did in the Scott study. The (CL) rate was .5mm/month, and the (SL) was .3mm/month. This fall off in rates in the second 10 weeks, when averaged with the first 10 weeks, slows the overall (20 weeks) rate of alignment. The (SL) was 1.5 mm/month for upper and lower and (CL) averaged 1.8 mm/month for upper and lower.

Sebastian in 20125 studied alignment efficiency in the mandibular arches of 24 patients. Wires tested were .016" NiTi (single strand) versus .016" NiTi (woven, coaxial).

Tooth movement was measured at 4 weeks, 8 weeks, and 12 weeks. The braided .016 NiTi produced the fastest alignment with average first month alignment of 4.9 mm/ month. The second and third months decreased to 3.6 and 3.1 mm per month respectively. Overall rate over 3 months was

3.9 mm/month. These rates were faster than those observed in past alignment studies by a factor of 2.6. The single strand .016" NiTi had an initial rate of 1.5 mm/month, and this decreased in the second and third months.

Efforts have been made recently to increase the rate of our tooth movement.

Some of these are vibration therapy, osteoperforation, infrared laser, and photo biomodulation. Most of these high-tech efforts are expensive, and some have not yet had control studies. Others have been studied relative to space closure and not initial alignment efficiency.

Osteoperforation has been shown by Teixeira, et al.,6 to increase the rate of tooth movement in rats. The small tissue traumas elicit the regional accelatory phenomenon that occurs as a healing response to trauma or surgery. These punctures physiologically mimic tissue trauma and bring about the release of cytokines and prostaglandins that are known to be associated with increased bone turnover and faster tooth movement.7-10 This concept has only had a controlled clinical trial evaluating the effects in cuspid retraction.11 This showed a 130% increase over a 28-day period. It has also been shown in one patient study to increase Invisalign® movement by 28%.12 Infrared laser has had a controlled evaluation that showed a 38% increase cuspid retraction.13 Vibration therapy has had one university administered study14 that showed initial alignment improvement of approximately 30% in the mandible compared to benchmark studies (Jones, et al.; O’Brien, et al.). This study also showed maxillary alignment to be 3 mm/month or 100% more than the early studies.

CONTINUING EDUCATION

Improving alignment by modulating archwire force

CONTINUING EDUCATION Photo biomodulation or the use of nearinfrared light is known to stimulate more cytochrome oxidase c production15 which mediates an increase in ATP. It is assumed that more ATP would facilitate tooth movement. Exposure in the facial area over the alveolar processes at a 850 mm wavelength for 60 minutes per week resulted in a 120% increase in the rate of alignment.16 The control rate was 1.9 mm per month, and the test sample rate was 4.4 mm per month.

Figures 1A-1B: 1A. A maxillary arch with only a .014 annealed wire in place. They are usually pressed lightly into the interproximal. 1B. A mandibular annealed wire is used in the same way but is .012 in size. The annealed wires usually only extend to the first premolars and are placed first and held by one or two elastomers until the NiTi wire is placed

Modulating wire protocol review This dual-arch initial wire protocol as described in a previous article17 starts treatment with a round NiTi archwire, the force of which is modulated by an underlying annealed wire. Figure 1A shows an .014 annealed wire by itself in place in the maxillary arch and an .012 annealed wire in place in the mandibular arch (Figure 1B). This wire has no spring but is usually pressed lightly into the interproximal areas to assure passivity. Figure 2 shows a maxillary arch (2A) and mandibular arch (2B) with both wires in place â&#x20AC;&#x201D; maxillary .014 NiTi with a .014 annealed wire and a mandibular .012Â NiTi with an annealed .012 wire. After 3 to 5 weeks, the annealed wire is removed. Removal is demonstrated in Figure 3. Ties are removed from one to three teeth, and the annealed wire is clipped usually between the centrals. The patient bites tightly on a cotton roll, and the clinician pulls the wire through the brackets with a Weingart pliers. The patient experiences no discomfort in this procedure, and it takes only 1-2 minutes to perform. Teeth move remarkably fast during ligation with the dual-archwires despite increased friction. But after removal of the annealed wire, the teeth move at a particularly rapid pace.

Examples of alignment during dualarch use and after Each of the following patients shows the initial arch irregularity (as per Littleâ&#x20AC;&#x2122;s18 Irregularity Index), followed by the change while the two archwires are in place together and finally the change after the annealed wire was removed. The duration and rates of movement are noted.

The etiology of rapid alignment At this point, one can only conjecture about the mechanism that results in such rapid alignment, but it does call to mind the biological system known as Regional Acceleration Phenomenon (RAP), which was first described by Frost19 and noted earlier.

Researchers have learned that RAP occurs 54 Orthodontic practice

In vitro testing Drs. Freudenthaler and Pseiner at the University of Vienna Orthodontic Department tested this dual-wire protocol. They used a 3D testing device developed by Dr. Hans-Peter Bantleon. This device (Figure 12) is capable of simulating a three-tooth segment and testing the force from a deflection or rotation of the middle tooth. Testing was done for rotation of the maxillary canine.

Brackets for the lateral, canine, and first premolar were placed, and the maxillary canine rotated 20°. In Figure 13, the test setup is shown with a twin bracket on the lateral and single brackets on the canine and first premolar. The lateral slot was .016 in.,

with many provocations â&#x20AC;&#x201D; e.g., tooth extractions, gingival flap surgery, mini-implant insertion, orthognathic surgery, etc. â&#x20AC;&#x201D; and this causes a more rapid movement of teeth than otherwise might happen.20-22 Melsen23 has even suggested that intrusion of incisors resulted in RAP with dense woven bone as proof of its involvement. So perhaps, unwittingly, the addition of dual wires as in this experience has resulted in RAP, which accelerates the movement of teeth.

Another possibility is that the resultant force to the periodontal membrane of this protocol may impart a force that dips below that of traditional wire bracket mechanisms and is more physiologic. Schwartz24 stated that capillary pressure of 25 gm would be the most physiologic with which to initiate tooth movement. Thilander, et al.,25 contend that most traditional initial orthodontic wires have the potential to impede tooth movement by causing sterile necrosis or hyalinization.

Many orthodontists begin treatment with a NiTi wire of approximately .014 in size. Our initial hope and assumption were that the force produced by this protocol modulated the .014 NiTi and the .012 NiTi (mandibular) to result in substantially less force.

CONTINUING EDUCATION and the canine and first premolar were .018 in. The interbracket distances were set to simulate average sized teeth and were 7 mm. Figure 13A shows the setup with one traditional .014 NiTi in place and Figure 13B with a .014 NiTi wire in combination with the .014 annealed wire.

The results of the testing for the maxilla are seen in Figure 14. For a 20° rotation, the .014 NiTi applied 722.6 cNmm and the .014 NiTi with the .014 annealed wire yielded 300.8 cNmm. This is 103.1 gms for the .014 alone and 42.8 gms when the annealed wire is present. The standard deviations were ± 56.1 and ± 44.2, respectively. Mandibular testing was done in exactly the same manner as the maxillary testing but with a .012 NiTi and a .012 annealed wire. With a 20° rotation, the .012 NiTi alone applied 588.1 (SD, 48) cNmm of force and the .012 NiTi with the annealed wire applied 221.5 cNmm (SD, 59) of force. This is 84.9 gms for .012 NiTi when applied alone and 31.5 gms when slowed by the annealed wire. Applying the standard deviations, the modulated .014 NiTi applied between 35-50 gm. The modulated .012 wire applied 23-40 gm. The mandibular test results are depicted in Figure 15.

The .014 by itself applies 2.4 times the force of the same wire when restrained by an annealed wire, and the .012 alone applies 2.7 more force when not restrained by an annealed wire. It may be that these very low forces are close to the true physiologic force and launch the cellular cascade of periodontal changes in nearly an ideal way. The cells of the periodontal membrane may be preconditioned, so to speak, to allow more efficient cellular activity. The force is extremely low, but also it is dispensed to the teeth at a gradual rate given the blocking nature of the annealed wire with the increased friction and resistance. The very instant that the annealed wire is removed, all patients report a sensation of increased force on their teeth.

A preconditioned periodontal membrane may be able to embrace this greater force and allow for more physiologic development and activity of end stage cells (osteoclasts and osteoblasts). This would promote and/ or allow more efficient and therefore more rapid movement.

Discussion

Figure 14: Test results for the maxillary arch. The .014 wire by itself applies 2.4 times the force of the same wire applied with the .014 annealed wire

Figure 15: Test results for mandibular arch. The .012 NiTi by itself applies 2.7 times more force than when it is modulated by the .012 annealed wire

This initial alignment technique produces greater rates of tooth alignment than any other previously reported studies. We have measured a group of 17 patients. Basically, these represent all recent patients that fit the criterion of significant arch irregularity that would have previously been aligned with a continuous arch without coil springs.

Certainly, a controlled study of this technique in the future would be appropriate and desirable. However, there is significant consistency in these patients with dramatic rates of movement. Table I shows the measured results of our patients. Table II shows a summary of results from previous alignment studies. The average rates of alignment from all previous studies is 2.6 mm/month. For this average, only the studies from 2006 forward were used. Where standard deviations were available, it was possible to calculate the fastest one rate measured in each study; these are also listed in Table II.

What about friction?

One of the anathemas for contemporary orthodontics has been friction. This has been encouraged by varied ways of securing wires in the brackets to produce less friction and binding. These are the “self-ligating” type brackets. The passive self-ligating brackets do allow easier sliding and apparently less friction and binding. If such movement is essential to initial alignment, and friction reduces this movement, then friction would be undesirable.

Dr. Dwight Damon stated in 2012,26 “What I also find interesting in Dr. Burrow’s paper is that in utilizing small round wires (.014, for example), friction (not binding) constitutes more than 95% of the total resistance to sliding, and that is exactly why low-friction passive ligation is more efficient than conventional ligation during the alignment phase.” Dr. Damon indicates that his experience and observations concur with the notion that friction is bad for tooth movement and especially in the early alignment phase.

A large segment of the profession has pretty much accepted this presumption.

Our clinical observations and the finding of this investigation and others would render this fear of friction invalid. The studies of Scott Volume 6 Number 3

200833 and Ong 201034 noted above found self-ligating (SL) brackets slightly slower, not faster in initial alignment. The dual-wire protocol described herein produces more friction than any technique known. The annealed wire plus the active wire combine for a total width of .028 in. in the maxillary arch and .024 in. in the mandibular arch.

This overfills the .018 x .025 bracket slots.

Then the annealed wire moves randomly into the interproximal area touching wings and tooth surfaces, which causes more restrictions. Additionally, we used elastomers and stainless steel ligations, which produce even more friction. However, the rates of movement accelerate significantly.

Treatment advantages Treatment time saved The graph in Figure 17 shows a comparison between the rate of traditional alignment methods and this protocol for different levels of arch irregularity. Obviously, clinicians save more time with patients who have greater initial arch irregularity. From 5 to 19 mm irregularity, the time saved ranges from 1.3 months to 5.4 months. In patients with less arch irregularities, the dual-arch technique helps clinicians finish earlier. In patients with more arch irregularities, their treatments do not exceed the estimated dates of completion. In each case, patients and orthodontists experience more pleasant orthodontic therapy. More importantly, the dual-arch technique affords clinicians the flexibility to spend more time to detail tooth positions and finish with a higher level of quality. There are a number of dental, societal, and economic forces at work currently that provoke less quality of orthodontic therapy. This procedure affords us the opportunity to improve our results within a reasonable time.

Less patient discomfort As was reported in a previous article in Orthodontic Practice US,35 this wire configuration dramatically reduces the patient discomfort experienced in the initial early alignment phase of our treatment. Of course, the early weeks and months of treatment build the foundational ties in a doctor-patient relationship that we all hope will have positive and mutually beneficial results. Patients and parents have an excitement during this early phase, and anything we can do to make the experience more positive (or less negative) produces pluses for our practice. Reduction of discomfort and allaying the apprehensive child certainly does this.

Figure 16: Graph of the previous study averages versus dualwire averages. The average rate of dual-wire movement is 3.12 times or 212% greater than past study averages. It is 1.56 times or 56% greater than the average of former study maximums. The maximum dual-wire rate (14 mm/mo.) is 2.45 times or 145% faster than the maximum rate found in all previous studies

Figure 17: Graph of the treatment time saved with dual-wire technique. X axis is months of time, and Y axis is degrees of irregularity present. Treatment time saved with the dual-wire varies directly with irregularity. The average gain ranges from 1.3 months at 5 mm of irregularity to 5.4 months at 19 mm of irregularity

Decreased root resorption Root resorption is an age-old nemesis for orthodontists and patients. Few initial alignment studies measure root changes, but Scott,3 Mandall,27 and Linge28 included this in their studies. Scott measured resorption at the mandibular central incisor. Sixty patients were divided between Synthesis™ (Ormco) brackets and Damon® 3 (Ormco) brackets. Root resorption was measured at 1.21 mm (SD 3.39) and 2.26 mm (SD 2.63) for Synthesis and Damon 3, respectively, Orthodontic practice 57

CONTINUING EDUCATION

These maximum rates range from 2.49 mm/month to 5.7 mm/month. Of the 17 patients we measured, only four had rates less than the maximum rate of all previous studies.

Figure 16 shows a graph of the relationship between the average and maximum rates of previous studies and those of the dual-wire method. The average rate of our study group is 1.56 times the maximum average of all former studies, and the dual-wire average rate is 3.12 times faster than the average rate of other investigations. The maximum rate measured with the dual-wire protocol is 14. mm/month. This rate is 2.45 times the maximum rate from all previous studies, which was 5.7 mm in the Sebastian study.

As you can see from Table I, this protocol produces consistently faster rates of tooth alignment. However, some patients do not respond as dramatically as others. Maxillary teeth align somewhat faster, and age seems to affect the outcome. Some adults do not align as quickly as the average adolescent.

The specific geometry of each irregularity, as well as individual variation in physiology, also plays a significant role in the alignment response. These resistance factors have not been examined enough to accurately predict which patients’ teeth will not respond as efficiently as the average patient.

CONTINUING EDUCATION during the initial 18 weeks. The difference between appliances was not statistically significant. Mandall noted an average of 1.18 mm (SD 1.4) central incisor root resorption during early alignment. This represented 18% of patients studied. Linge and Linge noted similar resorption (1.5 mm) on 16.5% of their patients.

While Scott, Mandall’s, and Linge’s levels of root resorption would typically not reach clinical significance, it is not insignificant as a treatment sequela. The extremes of resorption measured by Scott were 4.89 mm for Damon and 4.60 mm for Synthesis. These would have to be considered quite significant particularly for a lower incisor. Depending on the patient’s periodontal aging pattern, these could easily become clinically significant.

This dual-wire protocol has been used exclusively for more than 20 years. During this time, our root resorption level has been extremely minimal and less than when we used a traditional one-wire treatment initiation. Of the patients presented in this study, one adult experienced slight mandibular incisor resorption while the other 16 had no root resorption.

Universality of use This arrangement of wires should work with all bracket systems. Obviously, at this point only one bracket arrangement has used the dual-arch system, but it should enhance the alignment characteristics and reduce patient discomfort with any system.

Summary The profession has struggled for more than 90 years to produce more efficient tooth movement. The gold wires of Angle offered little hope in this pursuit. Stainless steel wires with greater resiliency and flexibility offered less force and more efficiency, but they did not increase patient comfort. Nickel-titanium archwires began to push orthodontics in the right direction by delivering wires with less force, more durability, and a greater range of action. However, this great advancement may have produced a generalized professional complacence.

We have neglected the research of Schwartz24 and Reitan29 in our contentment over the amazing range and duration of action of the NiTi wires. While these wires work continuously, they still apply too much initial force to achieve more efficiency and a more comfortable level of tooth movement.

In 2007 Berger and Waram30 did a test of the force levels of all initial NiTi wires. Of the 43 different NiTi wires measured, only 58 Orthodontic practice

one produced less than 4 gm of unloading force when deflected 1 mm. None yielded less than 57 gm when deflected 2 mm. Not surprisingly, that wire was the same woven NiTi wire studied by Sebastian. His study had the highest average rate of movement (3.6 mm) prior to the movement reported here.

The efforts of 10 orthodontic30 supply companies in the development of numerous NiTi wires has not produced clinical forces in the 25 to 30 gms range suggested by Schwartz and Reitan. This modulating wire technique has produced forces at or near the target set by these pioneers. And efficiency has jumped by a factor of 3 times. Apparently, the initial alignment phase is more about force levels than friction.

We have presented a new protocol for initial irregularity alignment that uses two juxtaposed initial wires that reduce the net force to the teeth to levels lower than currently possible with one wire. With one very small and inexpensive adjustment in initial clinical procedures, orthodontists, patients, and orthodontics generally receive several significant benefits. OP

3M Unitek: experience the science behind performance and efficiency

E

ver wonder what the technologically advanced orthodontic products offered by 3M Unitek have to do with Post-It® Notes or Scotch-Brite™ sponges? They’re all backed by proprietary 3M science — which when applied to everyday life improves the way we live and work.

At the 3M Unitek booth at this year’s AAO Annual Session, you’ll have the opportunity to see, touch, and demo products like Clarity™ ADVANCED Ceramic Brackets and the APC™ Flash-Free Adhesive Coated Appliance System. These products are designed by the top R&D minds at 3M to help practices move towards an esthetic treatment model that not only meets patient demand, but also maximizes performance and efficiency.

Offering an unbeatable combination of performance and beauty, Clarity ADVANCED Ceramic Brackets are made possible by the combination of multiple advanced 3M

technologies, resulting in an innovative, finegrained ceramic material that resists staining and discoloration throughout treatment. The ultra small brackets are strong and durable, with a unique stress concentrator and innovative design that allows for easy debonding on or off the archwire. Clarity ADVANCED Ceramic Brackets are also available precoated with a proprietary adhesive that shortens bonding time.

Born out of a strong history in adhesive technology, APC Flash-Free Adhesive allows orthodontists to move directly from bracket placement to bracket cure without removing the adhesive flash — eliminating the tedious cleanup step and reducing bonding time by up to 40% per bracket.* In addition to increased efficiency, the clear meniscus created by the APC Flash-Free adhesive minimizes gaps around the edges of the bonding base and the tooth surface, helping to protect the enamel under the adhesive

and contributing to a more beautiful smile after debonding.

“We know that sometimes, it’s not enough to just talk about a product’s benefits; orthodontists need that hands-on, tactile experience,” said Mike Lane, Vice President, U.S. Sales and Marketing. “Our booth at AAO will be a truly interactive experience that allows the science behind these products to come to life.”

To learn more about Clarity ADVANCED Ceramic Brackets and the APC Flash-Free Adhesive Coated Appliance System, visit the 3M Unitek booth at this year’s AAO Annual Session or 3MUnitek.com. *Based on feedback received from early users as part of 3M Unitek study #130220B, for direct bonding of brackets.

AOA Investments show commitment to supporting your practice

Q

uality and delivery are two of the most critical factors that influence the decision to partner with a laboratory. You want to select a lab that values the importance of these areas as much as you do. The right lab instills confidence that the appliance being constructed meets your design specifications, delivers the quality and fit you expect, and ships the appliance on time. You want a lab you can trust. Recently, AOA launched a campaign to hire skilled technicians, as well as to identify, hire, and train new technicians to meet the growing demand for both our current and future services.

We have added nearly 30 new technicians, and there are plans to add more. This investment’s sole purpose is to provide the same quality, service, and delivery that AOA has been known for since 1984.

Digital marketing to provide practice growth and profitability

T

he digital age is completely changing the way dental practices and patients interact. The need for personal contact from a patient’s perspective has been rendered less important with the advent of digital communications, as patients increasingly state they prefer the convenience of online, on-demand information. Interestingly, 93% of patients find it more convenient to find answers online compared to calling the office.

Patients have embraced the digital age, and practices must adjust to their preferences and be where their patients are — online. A digital strategy focused directly on patient engagement is now imperative to grow and maintain a long-term, sustainable practice.

Practice website — this is the cornerstone of your online presence, and the most comprehensive articulation of your practice brand.

Search Engine Optimization — this is a critical complement to your practice website as it ensures you are featured prominently within local search results.

Social media — this is your primary method for creating a consistent online dialog with existing patients and sharing their positive experiences with prospective patients in their network of friends, family, and colleagues.

Patient communications — this online accessibility is a great benefit to patients and greatly improves efficiencies for the practice.

Listings on vertical topical search portals and directories — this ensures your practice brand and value are shared with the Visit Sesame Communications at Booth No. 2305 ever-increasing volume of

prospective patients that look for information and online reviews on specific portals such as Healthgrades.com.

Your ability to get found online, appeal to patients no matter what device they are using to access your practice website, communicate with them through an online portal, and provide a robust strategy for review syndication will help you rise above competitors in your area and bring more new patients into your practice.

Specialty Appliances — digital innovation with indirect bonding

W

orkflow efficiency and precision bracket placement are two top priorities for every orthodontist. For many, a quality indirect bonding (IB) system is the answer for both. Recent technology advancements have greatly improved the success of IB, creating a new wave of orthodontists using indirect bonding in their practices.

Since 1981 Specialty Appliances has led indirect bonding innovation. Over the years, material and process enhancements have evolved to produce near-perfect transfer trays. Adhesives are better and more specialized to securely transfer brackets from tray to tooth. Model accuracy is the remaining piece and most critical key to IB success.

An exciting IB development is the use of highly accurate intraoral scanners. We have noticed a substantial improvement in model accuracy from digital scans. Over 50% of our current IB cases are submitted digitally, and those customers report minimal if any bond failures due to inaccurate models. In other words, IB trays fit better than ever from scanners!

Specialty Appliances continues to develop solutions that meet the demands of innovative orthodontists. Digital bracket placement for IB is one that shows much promise. First, we produce a digital setup of the finished case in ideal occlusion. Brackets are then digitally placed on the ideal setup using a full size straight wire to ensure slot alignment. Doctors then have the ability to review and approve the bracket position. The software remembers

the exact 3D bracket location from the ideal model to the malocclusion. Specialty’s proprietary process accurately transfers the digital bracket placement to the physical model.

Transfer trays are then constructed and shipped to the orthodontic practice.

Specialty Appliances continues to enhance precision indirect bonding, and digital advancements will drive this evolution. At the same time we believe our experience with manual bracket placement on malocclusion models is extremely accurate.

Simply eliminating bad models by adopting digital scanning can tremendously improve the accuracy of IB trays. Both manual and digital bracket placement methods offer a tremendous value to the profession, as witnessed by our many satisfied customers.

Digital impression scanning — improving workflow and the orthodontic experience James Bonham discusses how the modern laboratory can benefit the patient and the practice

T

oday’s technology-centric world associates high-tech with high quality. This holds true in orthodontics, and we have experienced meaningful advancements in recent years. These innovations save time, advance diagnostics, and greatly improve the patient experience in an orthodontic practice. The ability to take digital impressions is a game-changing technology that delivers meaningful benefits to doctors, staff, and patients — and also to the modern orthodontic laboratory.

Forward-thinking laboratories are searching for ways to improve orthodontic practice efficiency and overall appliance quality. Their experience can be an asset to new digital-scanning offices, offering process implementation assistance and tips for improving scanning techniques. Orthodontists will appreciate the benefits that digital impression systems can provide — optimized workflow, improved case acceptance, reduced impression redundancy, eliminated appointments, and best of all, the ability to produce precision-fit custom lab appliances.

One of the most important aspects of any orthodontic practice is case acceptance.

What better selling point to a new patient than discovering that this technology eliminates those goopy, gag-inducing impressions. Patients and orthodontists alike appreciate the fact that after the scan is achieved, treatment options can be reviewed and discussed immediately, and postorthodontic treatment scenarios can be simulated. This instant consultation tool provides a high-tech educational experience for the patient in addition to providing important information for the doctor.

Digital bracket removal

Digital scanning also improves efficiency by avoiding impression redundancy. The traditional process requires multiple impressions, one for records and a second for any lab appliance. A single digital impression produces 3D models for diagnostic records, and can also be sent to the lab for appliance production or indirect bonding trays.

While patients want the best treatment possible, they also want to achieve their results in the shortest time possible. The timesaving begins by eliminating the conventional separator appointment. The laboratory can digitally separate and fit the bands from the original records scan. Simply place the separators after taking the scan, and then deliver the appliance at the next appointment. Also, a technology-centered lab can make multiple appliances, like an expander and transpalatal arch (TPA), from this single scan. Sophisticated software allows the lab to expand the virtual model to the doctor’s

specifications before printing both construction models. The result is the ability for the orthodontist to deliver TPA appliances on the same day of expander removal. This example of digital workflow eliminates two appointments and several weeks of treatment time.

Fixed and removable retainers can also be delivered on bracket-removal day.

Many patients will inevitably misplace their removable retainers, causing their teeth to shift. Replacement retainers require a new appointment for impressions. The ideal solution to minimize relapse is to provide back-up retainers for the patient. Digital technology in the lab makes this a simple and affordable solution. Multiple removable retainers with integrated digital enhancements can be produced from one printed model. Orthodontists can increase efficiency and ensure longterm stability with new digital products like the GUARDIAN smile retention system from Specialty Appliances. Retainers can even be

That is what we thought when we started Focus Software back in 2010. We began developing Focus Ortho with the newest tools for a cloud-based platform. We set a goal to minimize clicks. Once a patient is open, all patient data had to be available from a single screen. We also made it easy to switch between patients and functionality. No more getting stuck in one screen when you need to take a patient call. But we wanted to do more. We added features that require third-party software from other companies.

Our goal is to be the one solution for all your office needs.

We have a management team with decades of experience in the Orthodontic Industry. Charlie Dunham, our president and CEO, was the founder of an industry-leading orthodontic software division. The software he created while there has been used by over 5,000 orthodontic offices around the world.

This experience building a business from the ground up gave him valuable insight on how to build a successful software company. This knowledge is essential since Focus Software now supports over 300 users throughout the United States and Canada.

When designing the software, we worked closely with a group that runs 15 orthodontic practices. They have over 100 users working on the program at the same time. They have been running Focus Ortho exclusively for the

You can also modify a specific day without affecting the standard template. Our office flow allows you to follow patients from the moment they reach the office; you can see if they are waiting, seated in a chair, or checked out from one intuitive screen. But, once again, we wanted more. So, we used the same screen to track doctor location and even show the order that patients should be seen. Easily enter treatment data by typing information or choosing from the pull downs. We even added the flexibility of entering next appointments from the back or the front desk.

Easily store and view images in the cloud

All you need is an Internet connection — because it’s all waiting for you, in the cloud.

Reporting — find your data Your software system is only as good as the data you can get from it. So, we designed a reporting system that gives you unparalleled access to your data. Of course, we can create traditional reports that are printed easily from the system. We have taken this to a new level with interactive lists.

Reports can be displayed in list view, and we have screens that allow you to choose financial and patient data from pull-down menus. Lists are easily exported in multiple formats, including Microsoft Excel. Using interactive lists, you can sort and filter data and directly open the patient. Interactive lists will reduce printouts, save trees and your time.

What does the future hold?

We are constantly striving to make Focus Ortho the best practice management software available. With this in mind, we are constantly updating to include new features and functionality.

Clear Collection instruments for clear aligner treatments In part 1 of a series, Dr. S. Jay Bowman explores instruments that help increase the utility of aligners and expand the scope of appropriate applications Let’s be clear: enhancing aligner treatments As clear aligner treatments have evolved and been progressively refined in the past 15 years, more advanced applications and increasingly complex malocclusions have been addressed.1-4 In addition, there has been more interest in tackling some of the specific limitations of moving teeth with plastic.5-7 Obviously, the progress of orthodontic treatment with traditional wires and braces has been advanced throughout the past century, but the techniques associated with a sequence of aligners are relatively recent phenomena.

Orthodontists with the most experience and enthusiasm in using aligners have worked diligently to improve the concept through better understanding of the limitations involved in more advanced treatment planning, especially when using adjuncts to enhance the associated biomechanics.4,8-13 The Clear Collection of instruments from Hu-Friedy (Chicago, Illinois, at www. hu-friedy.com) was developed with that aim in mind; namely, to help to increase the utility of aligners and expand the scope of appropriate applications (Figure 1).13

“Innovation is taking two things that already exist and putting them together in a new way.”

– Tom Freston

Adding intra- and intermaxillary forces The Clear Collection instruments have streamlined and standardized some procedures that orthodontists had already been providing, while opening up more options for other methods to accentuate or refine treatment. In the past, attempting to add intermaxillary elastics for correction of

Class IIs, IIIs, or midlines was problematic.

Some were cutting notches in plastic trays using scissors or nail clippers10 or attempting to adhere buttons to the trays — all unwieldy endeavors.

The Tear Drop There are occasions when orthodontic elastics are needed to assist with specific tooth movements or growth modification when using aligners. For instance, it may be beneficial to add elastic hooks or bonded buttons in different locations along the arch form on either the buccal or lingual. It would be beneficial to incorporate an elastic hook that cannot be dislodged from the aligner and that only requires a simple one-step squeeze of a pair of pliers to create. Most importantly, a hook that actually holds the elastic in place on the aligner.

Class I intramaxillary elastics connected from teardrop hook to a miniscrew (i.e., to support molar distalization) plus Class II intermaxillary elastics from teardrop notch to bonded button. 5B. Intermaxillary elastics hooked to bonded buttons to assist with seating of teeth into aligners and improve occlusion

Figures 6A-6D: The Hole Punch pliers can be used to relieve plastic impingement of gingival tissues anywhere along the aligners (e.g., incisive papilla irritation) Volume 6 Number 3

The Hole Punch The Hole Punch (Figure 4) is used to cut a half-moon shaped hole at the gingival margin of aligners. These half-circle cuts permit the addition of bonded buttons, bonded orthodontic tubes or brackets with associated hooks, or are simply used to relieve impingement of plastic on soft tissue. The Hole Punch can be used to produce cuts on either the facial or lingual of any tooth, anywhere along the aligners, whenever needed. Buttons bonded to teeth, rather than to the trays, do not cause dislodgement of the aligner.

During the progress of some patients’ treatments (after a series of aligners has already been fabricated and delivered), an orthodontist may wish to add elastics.

Bonded buttons can be added to hook up Class II or III intermaxillary elastics, biteseating elastics, Class I intramaxillary elastics to miniscrews (Figure 5), or elastomeric chain connected to buttons to correct dental rotations. The combination of buttons on molars (plastic relieved using the Hole Punch) along with elastic hooks cut into the plastic at the cuspids (using the Tear Drop) is a common method of employing orthodontic elastics.

In other instances, aligners will occasionally impinge upon gingival tissues and cause gingival pain or inflammation.

The Hole Punch can be used to clear the impingement of plastic in each of a series of aligners. A common location for that type of irritation is at the incisive papilla, behind the maxillary central incisors (Figure 6). Nipping along the gingival margin of a tray with the Hole Punch is also an option to relieve marginal gingival impingement on either the buccal or lingual.

TECHNOLOGY

Figures 3A-3B: Teardrop-shaped hooks retain elastics when aligners are seated, making the addition of “rubber bands” easier for patients to manipulate. Notches are made at an angle to resist forces applied by the elastics

“reservoir” to hold the elastic on the tray (Figure 3), thereby making it easier for the patients to seat their aligner and connect their elastics. In this manner, the patient is not fumbling with elastics, attempting to hook them in two locations since the elastic accompanies the aligner as it is seated over the teeth.

Teardrop notches should be cut at an angle to resist the line of force of elastics that are being employed (e.g., the notch is angled anteriorly at the mesial of the upper cuspid for Class II elastics; Figure 3). These hooks can be added anywhere along the clear aligner arch at the gingival margin on either the facial or lingual, whenever elastic forces need to be applied.

TECHNOLOGY Bootstrap mechanics If certain teeth are not “tracking” or are lagging13 behind (i.e., not fitting into the tray; Figure 7) Aligner Chewies™ are employed (Chewies™ Aligner Tray Seaters, Dentsply Raintree Essix, York, Pennsylvania). Patients are asked to hold the Chewie between the teeth in question and squeeze 10-15 seconds, release, and repeat for 5 minutes, 2-3 times per day 8,13 (Figure 8). In addition, Chewies are routinely used for the first few days when patients switch to a new pair of aligners to help them seat more completely.

Another option is to add elastics to forcibly erupt the teeth into the aligner tray.13,14 There are several methods to generate so-called “bootstrap mechanics” (Figure 9):13 1. An orthodontic elastic is stretched over the plastic aligner to connect to a combination of bonded buttons on both lingual and buccal of the tooth.

2. A bonded button is placed on the lingual of the tooth (plastic cleared with the Hole Punch). The Tear Drop notches are cut into the tray at the gingival embrasure spaces in the

buccal plastic on both the mesial and distal of the problematic tooth, and an elastic hooked from the buccal notches and stretched over the aligner tray to the button to produce an extrusive force.13 The Tear Drop and/or Hole Punch cuts are made in each tray in the series of aligners prior to their being delivered to the patient.

This concept is also useful when the extrusion of a tooth is needed for restorative purposes.

Other biomechanics that benefit from the application of elastic forces to aligner trays include the correction of severe rotations, posterior or anterior intrusion mechanics for open bites,11,12 and forces to control anchorage during molar distalization or

Figure 7: Aligner “lag” or lost tracking is most often characterized as an “air gap” between the incisal or occlusal of teeth and the plastic, indicating teeth are not following the prescribed tooth movement13

Figures 8A-8B: Aligner Chewies are held tightly been specific “lagging” teeth for 10-15 seconds. This process is repeated for 5 minutes, 2-3 times daily, especially when changing to a new pair of aligner trays A.

Dr. Mark S. Sanchez offers practical steps to keeping your private and professional information from the ne’er-do-wells

“Y

ou’ve just been infected. Send $500 within 72 hours, or we’ll wipe your computers.” That was the message one office administrator read after clicking on the icon that was supposed to provide her with information on how to run her office more efficiently. So what did she do? More importantly, what would you do?

Unfortunately for the medical doctor’s office in Macon, Georgia, the administrator rebooted her computer thinking that would solve the issue and didn’t mention the incident to anyone. Not at first. Not even at a time when the ransomware Trojan, Cryptolocker, was playing a starring role in world news. And, days later, the practice started to notice things going awry. Schedules wiped. Files corrupted. Computers acting funny. True to their threat, the ransomware Trojan that hijacked their computers

Volume 6 Number 3

was now wreaking havoc on their system.

An emergency office meeting was held, and through the discussion, the administrator finally realized her error. She just didn’t know. It was an honest mistake. None of the data was stolen (whew!) but in the end, the mistake forced the practice to manually re-enter 3 months’ worth of office notes, which increased labor costs by a quarter that year.

So, what would you have done? Still don’t think about it much? Yikes! Well, it’s OK that I do, and that’s why I wrote this article — to help you keep your valuable information from the destructive ways of those hackers, thieves, and no-good pilferers of the world.

I know that people want convenience above all else. Incredibly, a third of smartphone users in the United States still don’t set up password security on their phones.

According to Confident Technologies, 65% of users have corporate data on their phone, even though only 10% actually have a corporate-issued device. That’s pretty scary.

Security measures are now an absolute must, especially if your patients’ precious information is in your hands. Thankfully, it

doesn’t have to be all that daunting. Here are a few safety measures I require my staff to incorporate in my practice. And, I also encourage them to do the same in their personal online lives. This stuff is important.

Security rule No. 1: When in doubt, don’t click. Ever. When it comes to links and attachments in emails — even if it’s from someone you know and trust — resist temptation. Just give them a call to confirm they did indeed send it. And if it’s from your bank or other vendor, well, go ahead and check the safe way — by typing in the company’s website in your browser. Why the super-security measure here? Well, because websites can be faked when opened by email links.

Security rule No. 2: Open an online account the safe way. If the site lets you use a non-email address username, use a word or code that no one would guess. That way, you effectively have two passwords to double up on security.

Security rule No. 3: Give admin passwords for every computer. And make sure those passwords are at least 16 characters.

To keep it memorable, try stringing together Orthodontic practice 79

SECURITY GUARDS

Your data: (Relatively) convenient ways to keep it safe and secure

SECURITY GUARDS three or four words to create a phrase that’s not a common phrase or popular lyrics.

Something like “Cats grace the dance floor” or something nonsensical but easy to remember.

Security rule No. 4: Accommodate guests with a separate WiFi access point.

Prevent the accidental access to your practice and patient data with this very simple measure. An easy password like “MakeMeSmile” can add a little fun to the security measure, too.

Security rule No. 5: Limit laptop access. Grant few people on staff your admin access to laptops — I suggest just you and the office manager. For daily use by the rest of the staff, a non-admin account on each computer will work just fine.

Security rule No. 6: Think screensaveras-security-measure. Set your screensaver to turn on after your computer has been idle for 5 minutes and to ask for a password once you’re ready to get back on again.

Security rule No. 7: Create a hotspot lock. Create a hotspot in your lower left corner that instantly activates your locked screensaver. So the moment you have to leave your computer unattended, just move the cursor to the lower left corner of the screen and — bam! — instant lockout.

Security rule No. 8: Never store your PIN. Never. Don’t store credit card numbers or PINs to bank accounts anywhere on your computer. Nowhere. Really. Don’t do this.

Thieves are very clever and will find the information.

Security rule No. 9: Don’t be so obvious. Forget your password a lot? I do, too. To reset your password, many sites send you emails to reset information. They try to be secure but, really, m***z@gmail.com is pretty easy to guess. So I set up a special email that serves as the only avenue to retrieve my passwords via email should I forget. I never use it for anything else and, of course, I use a name that is not easily deduced. For example: CatsGraceTheDanceFloor@gmail. com becomes c***r@gmail.com.

Security rule No. 10: Use proven security-enhancing tools. I really like the password generator called 1Password because it keeps all the important information encrypted and secure. Even better, it helps me manage all the different usernames and passwords for every online account I have. That’s something to think about for your own accounts.

Just think of it this way: You need to protect your house and safeguard it against thieves in the physical world. A sign that 80 Orthodontic practice

Security measures are now an absolute must, especially if your patients’ precious information is in your hands. Thankfully, it doesn’t have to be all that daunting.

says you have an alarm is usually enough to discourage a thief, so he moves on to the next house. So you get an alarm to go with the sign as well as a giant Doberman pinscher named “Killer,” and chances are you’re going to be just fine. The same concept applies in the virtual world.

By now, you can tell I’m a bit obsessed with security. That’s why I made sure that topsOrtho™ software has built-in, thief-foiling measures, too. I know, shameless plug, but since you’ve read this far, here’s what we’re doing for orthodontist offices: We started with a Mac-based software system, so topsOrtho is just inherently more secure than its PC-based counterparts. To augment safeguarding measures, we added an increasingly long wait between each misguided password entered into the topsOrtho log-in window. Each incorrect passcode that is entered results in an increased delay before

topsOrtho will accept another passcode attempt. This is to slow down the ne’er-dowells who might use an automated passcode entry tool to try and guess your password.

The delay time increases exponentially with each incorrect entry, so that only a small number of attempts can be made. That’s just one of many security measures we included in our software. Of course, we’re always looking to add more.

There are so many more discussions and tips on the topic of security but only so much space on the page. But if you’re interested, I talk a lot about security on social media, so if you want to keep abreast of the latest without doing the all that exhausting research yourself, you can follow me and topsOrtho on LinkedIn (tops Software), Facebook (facebook.com/@topsOrtho), and Twitter (@ topsOrtho) for more on the subject.

Don’t let them win. Stay safe. OP Volume 6 Number 3

American Orthodontics PowerScope™ Class II Corrector Innovative, effective Class II correction

A

merican Orthodontics is revolutionizing Class II correction with PowerScope™ — a ready-to-use chairside solution that delivers an unmatched combination of patient comfort and ease of use. American Orthodontics developed PowerScope in conjunction with Dr. Andy Hayes, a clinical instructor in the St. Louis University Department of Orthodontics, who runs a private practice in Ballwin, Missouri.

PowerScope is a one-piece, one-sizefits-all appliance that goes from package to treatment in just seconds. There’s no need for any lab setup, assembly, or measuring. It attaches wire-to-wire for quick, easy installation and eliminates the need for headgear tubes or special band assemblies. Wire attachment mechanisms hang on the archwire, and the screw then acts as a “fourth wall” that holds the appliance in place.

PowerScope does not “lock” onto the wire and freely slides to allow for any dentoalveolar correction associated with a Class II malocclusion.

PowerScope’s internal NiTi spring delivers 260 grams of force throughout treatment, which can translate to reduced treatment time compared to other Class II Herbst appliances. Crimpable shims then facilitate activation and advancement control throughout treatment.

American Orthodontics is dedicated to continuous improvement and has made several recent enhancements to PowerScope.

They include: • A prominent laser marking ID for quick and easy activation of the appliance • A magnetic hex head driver for safe delivery of appliance during installation • Improved screw and attachment mechanism design for increased durability against patient abuse during treatment “The large learning curve associated with other multi-piece appliances is eliminated,” says Dr. Hayes. “PowerScope is a simple, extremely efficient appliance that can be the ‘go-to’ treatment for Class II correction that you can count on to work every time.

“Installation of PowerScope takes very little time and offers a much more favorable force vector for Class II correction than other appliances,” says Dr. Graham Jones of Monroe, Washington. “PowerScope’s design and the direction of its forces means compensations like Class II overcorrection or complicated anchorage techniques common for other fixed Class II correctors aren’t necessary.”

Patients will be pleased with the increased comfort PowerScope brings. There are no external springs or distally extending pistons; lateral movement is maximized with ball and socket joints; and smooth, rounded edges and a low profile mean the cheeks won’t get that “puffed out” look that comes with other Class II solutions.

“My patients find PowerScope to be by far the most comfortable fixed Class II appliance of those that I have used,” says Dr. Jones. “Range of motion is not impaired by the PowerScope, and there’s virtually no tissue impingement.”

Carestream Dental’s latest release of Logicon Caries Detector 5.1 further automates the detection process and produces improved displays of caries sites, making exams and diagnoses even more efficient than in the past. Logicon 5.1, the only commercially available FDA-approved computer-aided radiographic caries diagnosis software, is a unique and clinically proven tool that helps practitioners detect and treat interproximal caries at an early stage, enabling minimally invasive treatments.

In fact, studies show that Logicon more than doubles dentists’ capability to find early caries in the dentin over traditional visual diagnostic methods.* For more information, call 800-944-6365, or visit www. carestreamdental.com. *Tracy KD, Dykstra BA, Gakenheimer DC, Scheetz JP, Lacina S, Scarfe WC, Farman AG.

A perfect fit.

“I have been using clear aligners to treat a broad spectrum of my orthodontic patients since 2000 and have grown to appreciate the quality and capability of the ClearCorrect system: the online portal is simple and easy to utilize; I do not have to frequently return setups for revision; the aligners always fit well; the staff and support personnel are responsive and pleasant to work with when needed. For the best ROI and ‘bottom line’, ClearCorrect is my choice for a comprehensive clear aligner system.”

—Dr. Ken Fischer, orthodontist.
