e have all had the experience of purchasing something only to realize we have been duped. Whether we were intentionally taken advantage of or just didn’t do our homework, the result is the same — we feel unfulfilled. The results don’t live up to the promises.

When dealing with purchases in the dental field, it is the support that most often makes the biggest difference. When you buy a dental implant surgical kit and some implants, you may find yourself in a situation in which the person giving you surgical advice has never actually placed an implant. A weekend course on implant placement doesn’t Terry L. Work, DMD always give you the answers you need during your surgery. The number and combinations of factors can be daunting.

Mentor is defined as “someone who guides another to success.” If there is someone who is doing something you would like to do, then who better to learn from? If you would like to learn to play the guitar, find a teacher who can guide you through the process. However, not every skilled person is a good mentor. It is important to find someone who “speaks to your listening.” In other words, it is important that the relationship is based on trust.

In the field of dentistry, there can be disagreement about either treatment recommended or treatment rendered. Some dentists feel they are in competition with their colleagues. The truth is, there is room for everyone to succeed, and cooperation among peers raises the profession as a whole. Patients hate to go to a new dentist and have him/her say that the treatment they received at the previous dentist was not done properly. It is good practice to refrain from criticizing a procedure to which you were not present. Rather, simply provide patients with the information they request from you. There are, of course, circumstances in which the standard of care has been grossly ignored. As a colleague once told me, “No matter how good we think we are, sometimes you just have a bad outcome.” It is our responsibility to minimize those “bad outcomes.”

In implant dentistry, the technical skill required is not as demanding as most of the procedures dentists perform every day. It is usually the case selection that causes problems for the inexperienced clinician. The sales pitch of the implant representative can hypnotize us into thinking that placement is as easy as a buccal pit. I find that nothing replaces preparation.

While looking for good continuing education relating to implant placement, it’s nice to have someone close to you to consult. It is a little unrealistic to expect your local oral surgeon to train you to do something he/she would rather do for you, but we all have an interest in personal growth. The surgeons expand their procedures to experience this personal growth.

Why should we be any different? The important thing is that it needs to be done with the patient’s best interests in mind. If this is always kept in mind, the path to growth is much easier.

The idea of mentoring is that you have someone with whom you can consult to help with case evaluation and surgical techniques. Unfortunately, we don’t get to choose the implant cases that present at our office. It is of great value to have an experienced person at your disposal to help with individual cases. The value is in the ability of the experienced person to foresee possible problems and avoid unwanted outcomes. There may be cases in which the recommendation is to refer to the surgeon for placement, and the clinician can restore the case. Your patients come to you because they trust you; they would rather not go to another office if you can provide them with what they need.

Mentoring programs are a great way to provide the service your patients deserve.

New Mexico Mission of Mercy

What can you tell us about your background?

I grew up in Anderson, Indiana, and was born and raised as a Hoosier. It was a great place to grow up. I learned to love outdoor activities with lots of camping and became an Eagle Scout. I attended Indiana University in Bloomington and graduated in Biological Sciences and Psychology in 1973. I attended Indiana University School of Dentistry in Indianapolis and graduated in 1977. I had several uncles who were physicians, and I knew I wanted to go into some field of medicine. Dentistry seemed to be just the right fit.

My high school girlfriend and wife of 38 years and I reacquainted while I was in dental school. We married 1 month after graduation, packed up a U-Haul®, and moved west to the Navajo Indian Reservation in Window Rock, Arizona. I served with the Indian Health Service, U.S. Public Health Service for the next 3 years as a Facility 6 Implant practice

Dental Officer in a unique and fascinating cultural environment.

By then the West had grown on us, and we wouldn’t turn back. I established a private general dentistry practice in Rio Rancho, New Mexico, contiguous with Albuquerque, fueled with a 1980 bank loan with an interest rate of 24.25%. (Ouch!)

Is your practice limited solely to implants, or do you practice other types of dentistry?

I practice comprehensive dentistry and utilize implants as an integral part of my treatment planning. A significant part of my practice is reconstruction using the principles of Orognathic Bioesthetics International (OBI).

Why did you decide to focus on implant dentistry?

I began restoring dental implants in 1984 after attending training at a Brånemark

Dr. John Crisler

course. A periodontist began using my office as a satellite in the 1980s, and he was placing the IMZ® implants with its intramobile element developed by Axel Kirsch in Germany. I saw the great opportunity to help patients with both fixed and removable dental prosthetics using implants, and I have developed my continuing education and training in that direction since then.

PRACTICE PROFILE Do your patients come through referrals?

We frequently receive referrals from existing patients, other dental professionals, and the State of New Mexico Workers’ Compensation Program, where I have helped people from all over our large state, primarily with TMJ-related injury issues. Many of these patients have benefited from implant-retained restorations.

How long have you been practicing implant dentistry, and what systems do you use?

I have been restoring dental implants for 31 years, and I began placing dental implants 13 years ago. I have accumulated no less than 15 different surgical and restorative systems during that time. I have had the most success with the internal connection systems. I currently use the Ossotanium implant system, which uses nanoparticle titanium implants.

These implants are twice as strong as implants using conventional titanium, and the osseointegration time and loading times are significantly reduced. This facilitates immediate loading and temporization, a much appreciated advantage to patients over removable appliances for temporization, especially in the esthetic zone. The Ossotanium system also offers bone level, tissue level, one-piece, and mini implants. We have been able to offer immediate temporization through immediate loading, utilizing the system’s temporary abutments and sleeves to fabricate provisional restorations.

What training have you undertaken?

I have been an avid believer in continuing education ever since graduation from dental school. I have sought and achieved Fellowship and Mastership in the Academy of General Dentistry and have completed over 3,000 hours of continuing dental education.

Membership and training in courses offered by the AAID have also been very valuable to me. I was fortunate to have Dr. Walter Schuman, a principal with the BASIC Dental Implant System, mentor me and coach me in the actual placement of my first implants in my office. For the last 10 years, the greatest and most valuable source of my hands-on training has been through the New Mexico Dental Implant Study Club, which I helped initiate. Our study club has up to eight members at a time, and we meet 8 times per year, for treatment planning and surgical sessions. We have been privileged to have the mentorship and support of Dr. Steven Holbrook since our inception.

Who has inspired you?

My personal inspiration has come from my faith and clergy over the years who have guided me along the path of serving my fellow man with my God-given ability to help other people. Professionally, Dr. Steven Holbrook has been a great inspiration and mentor with his seemingly boundless energy and enthusiasm toward excellence in dental implantology.

What is the most satisfying aspect of your practice?

The heartfelt thanks and show of appreciation from patients whom we have served are the most satisfying aspects of my practice. Dr. Albert Schweitzer said, “I don’t know what your destiny will be, but one thing I know; the only ones among you who will be really happy are those who will have sought and found how to serve.”

Professionally, what are you most proud of?

I have many patients who have placed their trust in me since the early 1980s when I opened my private practice. As I have acquired new technologies, and as the science of implantology has grown, I have been able to offer the benefits of implants

Front desk

to an increasing number of patients. My patients now have children and grandchildren who still consider me their dentist. I am also proud of the relationships I have developed and nurtured with dental colleagues and specialists, as well as with my wonderful staff. I served as a Co-Chairman for the 2014 New Mexico Mission of Mercy, a large-scale, 2-day free dental clinic that provided just over $1 million of dental treatment. In 2 days of joyful giving, 1,344 volunteers, including dentists, hygienists, assistants, and community volunteers, served 1,055 patients with 8,633 procedures.

What do you think is unique about your practice?

We have a beautiful location with our operatories and balcony looking out over the Rio Grande Valley and onto the Sandia Mountains. We offer comprehensive care utilizing the diagnostic and reconstructive principles of Orognathic Bioesthetics International (OBI). We take the time to educate patients about ideal or optimum treatment after listening to their concerns, goals, and factors that influence their decisions about treatment. When patients have missing teeth, we offer them the same treatment we would want for ourselves and our families.

Dr. Crisler and family

What has been your biggest challenge?

want to treat patients with the same respect and dignity I would want for myself. I am currently blessed with having the best staff of my career in dentistry. They frequently speak of their appreciation for me, and I try to reciprocate with praise for a job well done to them. So much of the success of a dental practice depends on having a great supportive staff. I love going to work and treating people with the help of my dental family.

Balance and harmony in life are very important. It is easy for me to enjoy our profession so much that the other components of love, recreation, family, friends, and faith do not get an adequate share of time.

What would you have been if you had not become a dentist?

I think I would have enjoyed being an electronics engineer because of my love for gadgets. With the amazing improvements and technology in digital photography, I may still become a professional travel photographer. But for now, I’m still getting a lot of enjoyment from the practice of dentistry.

What is the future of implants and dentistry?

I think we will see much more utilization of the nanoparticle-structured titanium implants because of their greater strength and faster integration time, which will permit us to provide excellent service in a shorter period of time. As patients become more educated about the benefits of dental implants in general, more demand will occur for the services of qualified and trained generalists and specialists who can provide these services.

What are your top tips for maintaining a successful practice?

What advice would you give to a budding implant dentist?

Challenge yourself to move forward with your education and experience in implant dentistry. Ralph Waldo Emerson said, “Unless you try to do something beyond what you have already mastered, you will never grow.” Go to implant courses and participation training with different systems.

Even though each system has its own unique qualities and selling points, you will discover and be reinforced by the commonalities among them. Find a mentor for support and learning, which is always a two-way street.

Find a dental lab that gives you great support for implant cases. I have been blessed with having the support of two great labs in New Mexico — Esthetic Dental Arts laboratory and New West Dental Lab.

What are your hobbies, and what do you do in your spare time?

My wife and I have enjoyed traveling to many parts of the world, and we have many more to see. Planning our trips is an ongoing

pleasure in our spare time. I enjoy photography, and this has been an important part of our travels, internationally as well as within the United States, and our beautiful Land of Enchantment, New Mexico. We enjoy cruising both on river ships throughout the world and on oceangoing cruise ships. I had the pleasure of working with Holland America Line in the SeaDentist program for two or three cruises per year for 5 years, cruising in many parts of the world and doing dentistry onboard the ships. SCUBA diving has been an enjoyable hobby of mine since I was a teenager. Our yearly trips to Mexico include diving excursions. IP Volume 8 Number 5

CASE STUDY

Post extraction, immediate placement and restoration in the mandible using Neodent DriveÂŽ implants Dr. M. John Matos discusses an immediate placement technique to produce a desirable outcome Introduction Immediate placement can produce esthetic and functional comfort,1 while also preserving the width and height of the alveolar bone and providing a patient with a reduction in treatment time and expense. The following case demonstrates the preferred outcome to multiple tooth extractions using the immediate placement and loading technique.

Patient presentation A 49-year-old male presented to the office with obvious advanced periodontal issues that were limited to the mandibular anterior teeth. The teeth were no longer functional due to increased mobility, significant flare, and patient discomfort. The patient had a medical history of atrial fibrillation, a knee arthroscopy without complications, hypertension, and hyperlipidemia. The patient had no known drug allergies and was taking sotalol, diltiazem, pravastatin, and lisinopril.

Following the evaluation of the periradicular radiograph, the clinical recommendation was to extract teeth Nos. 23 through 26 and place two dental implants with a prosthesis (Figure 1).

1:100,000 units — total of 9.0 mL. After local anesthesia was administered, the lower incisors (Nos. 23 through 26) were extracted carefully to maintain alveolar bone; no subperiosteal flaps were elevated.

After extraction of the teeth, aggressive and meticulous curettage of the hard and soft tissues was required around the surgical site.2 The most serious osseous defect was in the tooth No. 24 area. The osteotomies were prepared, and it was noted that the vascularity of the extraction sockets were excellent, but the relative density of the bone was not expected in the para-symphysis.3 Using copious amounts of irrigation, the osteotomies were drilled to prepare for implant placement.4 Due to the density of the bone, implants featuring an aggressive thread design (NeodentÂŽ CM Drive) were chosen to provide the necessary torque and primary stability to enable immediate loading of the prosthesis.5 The inserted implants gained 60 Ncm insertion torque, which is acceptable for the immediate loading of dental implants.

The implants were placed 2 mm subcrestally6 (Figure 2).

Prefabricated abutments were selected to minimize the impact on the adjacent hard

Surgical treatment

tissues but also aid in the support of the adjacent soft tissues (Figure 3).

Chairside temporary restorations were fabricated, and the temporary prosthesis/ stent because of subgingival margins acts as a support to the soft tissues, maintaining or even creating the interdental papilla.7 In coordination with the patient and his esthetic demands, the decision was made to create a five-tooth provisional for better esthetics.

CASE STUDY

Figure 4

Figure 3

The patient was given post-surgical instructions to eliminate incising with the anterior teeth for 6 weeks and included the use of penicillin VK 500 mg QID #40, Motrin® 600 mg QID #40, and Norco 10/325 mg #40 1 or 2 po q4-6h prn for pain.

At 7 days, the post-op response in the soft tissue was excellent (Figure 4).

At 28 days, it is easy to appreciate the maintenance and creation of the papilla “effect” in the tooth Nos. 25-26 papilla area (Figure 5).

At the 3-month mark, there are excellent soft tissue maturity and a healthy band of keratinized tissue (Figure 6).

Removal of the temporary also reveals mature tissues and good soft tissue collars around the abutments, which may be changed as needed, for optimized form, function, and hygiene.8 At the 5-month mark, the abutments used at the time of surgery were not changed, but rotated for more ideal positioning in preparation for the fabrication of a final prosthesis (Figure 7).

The soft tissue collars around the abutments were allowed to mature for 4 weeks, and the patient returned for final impressions.

The soft tissue around the abutments proved to be quite resilient; retraction of the “sulcular” soft tissue was very difficult.9 Various options were discussed with the patient, and it was decided to impress to the base of the natural sulcus since the retention/stability of the temporary prosthesis was excellent. The patient consented, understanding that in the future should there be any compromise to form, function, or hygiene, the prosthesis may need to be changed out.

CASE REPORT

Reconstruction of resected jaw assisted by 3D technologies Dr. Ronald Delmanto required creative treatment planning for a patient after jaw resection

W

hen a patient named Al visited his general dentist several years ago, a routine appointment turned into a lifechanging event. After an FMX series, a review of the radiographs showed suspicious dark radiolucent areas below the teeth and in the bone. The patient was referred to the University of Medicine and Dentistry in New Jersey, where it was ascertained that Al had multiple ameloblastomas, a rare, noncancerous (benign) tumor that develops most often in the jaw near the molars. If these extremely aggressive neoplasms are not excised completely, they can reoccur and result in bone destruction. The patient had no symptoms. After diagnosis and oral surgery, the road to both physical and esthetic recovery required creative planning, and 3D imaging played a significant role in the reconstruction process.

To remove these lesions, the surgeon resected the portion of the mandible that extended from the mesial of tooth No. 18 around to the mesial of tooth No. 27, quite an extensive area. After the resection, a metallic bar was screwed into the intact portions of his jaw for support. At a second surgery, the jaw was reconstructed utilizing a cadaver rib and bone marrow from the patient’s hip. After the jaw resection, the patient was dejected.

He could not chew on left side at all, had no anterior teeth on the bottom, and he was very unhappy with his esthetic appearance.

He was an active and robust man in his mid-50s, a retired New Jersey state police major, so this was crushing from both a functional and esthetic point of view.

After the graft was allowed to mature for 8 months, the patient came to me for a

reconstruction treatment plan. An i-CAT™ 3D scan (i-CAT™) was taken, and treatment planning software was used to accumulate all of the data and measurements necessary to complete the reconstruction and devise a plan for this rather challenging anatomical issue. After the resection, the jaw had ended up too far buccally and labially for the type of treatment that I first had considered. I had originally intended to perform routine crown and bridge, but in that case, the buccal aspect of the teeth would have protruded too far into the cheek and the lip. I had surgical guides created and then (Figure 1) surgically placed the implants (Figure 2), and then conferred with the laboratory. Instead of crown and

CASE REPORT bridge, we created custom castings and a framework that attached to the implants (Figure 3). I planned the framework to protrude more lingually, and then placed LOCATOR® attachments (Zest Anchors) on the framework and reconstructed the jaw with a removable appliance (Figures 4-6).

This treatment plan worked very favorably — it restored the dentition, and by utilizing a removFigure 5: Prosthetic placed, occlusal view Figure 4: Removal appliance that attaches to implant able appliance, we reconstructed much of the tissue that he lost after the oral surgery. Before reconstruction, the left lower side of Al’s face appeared to be collapsed, as though his lip had no support.

When his case was completed, we were able to reconstruct much of that lost tissue with acrylic and the teeth placement. As a result, he regained the ability to chew on that side, and esthetically, he had a fuller lip support and looked basically the same as he did prior to the surgery (Figure 7).

From the time the jaw was resected, the process took approximately 1½ years.

A CBCT imaging system was a very valuable asset to this case. Besides the extremely precise data that I gained from the 3D scans, I performed the surgery utilizing the CBCT scans in conjunction with surgical guides. I am proud to say that I presented this case to a clinic in Miami several years ago, and Dr. Carl Misch, whose implant course I have taken several times, complimented me about how straight and in-line the implants were. I would Figure 6: Prosthetic placed, facial view not have been able to plan and implement the case with such accuracy and precision without the information from the i-CAT scans and the surgical guide created from the scan data, both of which helped me to determine the precise spacing and parallelism. The spacing is so good that we have had no residual problems. In fact, normally, I have to change the male inserts for the LOCATOR attachments that wear out periodically, depending on the individual patient’s chewing habits. I have not changed Al’s LOCATORS since 2006 because he is biting so evenly.

CASE STUDY

Immediate implant placement: cutting treatment time in half Dr. Charles D. Schlesinger illustrates a case involving immediate implant placement

I

mmediate placement of dental implants has become a successful and dependable treatment modality in today’s modern implant practice. One of the biggest advantages is the drastic decrease in overall treatment time for the patient. In today’s world of instant gratification, an average decrease in treatment time from 7-8 months in traditional extract/graft/wait/place/wait protocol to a much more palatable 3-4 months is a true practice builder. Though immediate temporization or restoration is the ultimate goal in mind when extracting a tooth, many times this does not constitute a prudent treatment plan. Factors to consider include primary stability sufficient enough to load, prosthetic considerations, and the size of the resulting extraction socket.

The success rate of immediate implant placement approaches the success rates of delayed placement1; therefore, with the right technique and the correct implant, this should be done as routine rather than the occasional treatment option.

Case study A 65-year-old female presented to the clinic with a non-restorable lower right first molar. The tooth had an existing large restoration with extensive re-decay (Figure 1). The patient was given the following treatment options: 1. Extraction without bone grafting 2. Extraction with bone grafting 3. Extraction with immediate implant placement and bone grafting The patient chose option No. 3, and since there were no medical issues to contend with and no evidence of infection, the decision was to commence with extraction along with immediate implant placement the day it was agreed upon.

Procedure Profound anesthesia was carried out with 4% Septocaine® (Septodont USA). Although an inferior alveolar nerve (IAN) block is not usually performed for implants placed in the mandibular arch, it was determined that the

benefit of his type of technique outweighed the possibility of discomfort for the patient since concomitant extraction was being performed. Along with the IAN block, a long buccal block was utilized. This type of anesthesia should only be carried out if sufficient 2D and 3D radiographs are available.

Once the patient reported that she was numb and comfortable, tooth No. 30 was atraumatically extracted. After removal of the crown, the tooth was sectioned through the furcation with a high-speed handpiece (Kavo USA). A 301 elevator was used to split the roots further and was followed by the use of a 151 forcep. Each root was removed individually with particular attention to preserving the inter-septal bone. After removal of the tooth roots, the socket was debrided with a serrated curette and inspected for bony integrity (Figure 2).

A 557L surgical carbide created a purchase point on top of the interseptal bone. This allowed a 1.8 mm pilot drill to be used to create the initial trajectory between the mesial and distal root sockets

During this time, he became an educator for various dental implant companies and has lectured across the United States, Canada, the United Kingdom, and China. In 2012, he became the Director of Education and Clinical Affairs for OCO Biomedical and, in 2013, took on the position of Chief Operating Officer.

The imbedded tapered platform is at home in either bone or soft tissue. Another advantage of the divergent platform is that it will contribute, along with the bull nose auger tip, to the patented dual stabilization of the implant. Finally, the increase in platform size helps seal the top of the socket to contain the grafting material.

The final osteotomy will stabilize the implant by use of the remaining buccal and lingual chords of bone along with the auger tip condensing bone at the apex.

The implant was delivered by hand and then torqued into position. The final torque value was 30+ N/cm (Figure 10); enough for primary stability, but not sufficient enough

(Figures 3 and 4). Immediate placement, especially in molars, can be challenging with respect to creating an osteotomy while fighting the natural tendency for the bur to wander into the path of least resistance.

In this case, that path would be either the mesial or distal sockets.

Once a path of insertion was established, the osteotomy was enlarged using a progression from a 3.7 mm osteotomy former (Figure 5) to the final osteotomy former for a 5.0 mm implant (4.7 mm) (Figure 6).

The usual two-step protocol was not followed in order to make sure that the maximum amount of bone was preserved for implant placement (Figure 7). A 5.0 x 12 OCO Biomedical TSI implant was chosen for this case (OCO Biomedical). This particular style of implant has an emergence from the 5.0 mm body to a 5.7 mm restorative platform (Figure 8). The divergent imbedded tapered platform has a 32xx machined surface rather than being polished; this allows the implant to be placed at the appropriate restorative level without regard to the “collar’s� position (Figure 9).

CASE STUDY for immediate loading. In order to immediate load this implant, it would require at least 45 N/cm and/or at least an ISQ value of 64 with an Osstell meter.2 After the implant was in position, SteriGraft™ DBM putty (OCO Biomedical) was placed in the remaining socket around the implant (Figure 11), since the buccalimplant gap exceeded 2 mm.3,4 In order to confine the graft material, an RCM6 (ACE Surgical) Type 1 collagen membrane was used to span the socket opening with at least 5 mm of membrane extending beyond the opening. A technique was utilized where the cover screw was placed through a hole made in the membrane (Figure 12).

This hole allows the cover screw to stabilize the membrane without having to use tacks; a 3.0 silk suture (Ethicon) was used

in an interrupted fashion to hold the soft tissue immobile during healing (Figures 13 and 14).

Since only the minimum primary stability was achieved, the implant was given 3 months for osseointegration to take place.

During this time, the graft was replaced with host bone under normal healing conditions, and keratinized tissue advanced over the membrane by secondary healing (Figure 15). Once complete healing was verified by radiographs and the stability checked with an Osstell meter, the decision to commence the restorative phase was decided upon.

The cover screw was removed, and a 5.5 mm tall solid crown and bridge abutment was torqued to 30 N/cm and then re-torqued after a 5-minute interval elapsed.

This re-torquing of the abutment will counter

any pre-stretch of the metal caused by the first tightening.

A tissue retraction impression pickup (TRIP) coping was snapped into place. Light body VPS material was used to capture the detail of the soft tissue and adjacent teeth.

Heavy body VPS in a stock triple-tray was used to complete the final impression (Figure 16). A bite registration was also taken at this appointment as a backup to verify the occlusion.

A metallic analog was placed (Figure 17) into the TRIP, and the impression was sent to the lab for fabrication of a PFG restoration. The cover screw was replaced and the patient dismissed until the delivery appointment.

At the final delivery appointment 2 weeks later, the final restoration was tried in, and the

Immediate implant placement is not only a viable treatment option, but one that most patients will choose if given the choice. It is important for the practitioner to make sure that sound implant protocols are followed with respect to medical history, current oral condition, and the prerequisites necessary for primary stability. The ability to cut down the overall rehabilitation time by potentially a factor of two not only produces a satisfied patient, but also is benefit for any dental practice trying to increase its practice performance and patient care.

SEEING THE LIGHT

The 10.6 µm SuperPulse CO2 laser may alleviate the late implant failure linked to tissue tension Drs. Jack Krauser and Peter Vitruk explore soft tissue recession prevention with the CO2 laser Introduction In 1986, Albrektsson, et al.,1 proposed criteria for evaluating implant success based on clinical and radiographic evidence of osseointegration: the healing of bone around implants to produce direct anchorage of the implant that is then maintained during functional loading without the growth of fibrous tissue at the bone-implant interface.2 The extensive body of peer-reviewed literature published in the field of implantology since then offers a number of additional criteria to define implant success. These criteria include the absence of peri-implantitis, lack of pain and implant mobility, radiographic evidence of minimal crestal bone loss, clinical function, esthetic outcome, and patient satisfaction.1,3-5 Despite having predictable outcome and long-term success rate, implants sometimes fail — i.e., require removal or have already been lost.5 Implant failures may be classified as early, when the implant body fails to get osseointegrated, or late, when the implant body is unable to sustain the osseointegration.6 A number of clinical studies have identified various risk factors that may cause or contribute to implant failure.3,5,7 Among the factors associated with implant failures are bone quality and quantity, history of periodontal disease, edentulism, location of the implant, bacterial contamination, delayed wound healing, surgical trauma, implantrelated factors (type of implant system, implant surface), and others.

Smoking, occlusal overload, and other biological and biomechanical factors have also been noted to compromise implant success.8,9 More recent studies have concluded that another significant factor of implant success is soft tissue thickness (or biotype).10-13 Some studies name lack of adequate keratinized tissue or attached mucosa among contributing factors of implant failure.14-16 This topic is controversial, and more studies are needed to prove or disprove its validity.

Figure 1C: 2007 cross-sectional image of the lack of bone in the facial and apical aspect of the implant. Perhaps a prophylactic release of the frenum pull would have prevented this outcome (Courtesy of Dr. K.B. Park)

Tension problem — alarming trend This article focuses on an alarming issue of implants loosing support and integration due to excessive soft tissue pull or tension from a shallow vestibule and/or dense frenum pull. We now have an abundant number of cases that exhibit tissue recession and possibly late loss failure. For example, Figures 1A-1C show a case of late implant failure. In 1996, the patient received an implant on tooth No. 8. The immediate result was very good, both functionally and esthetically (Figure 1A). However, the 2007 follow-up visit revealed severe gingival recession (Figure 1B depicts the recession and distinct frenum pulls). The cross-sectional image from 2007 (Figure 1C) demonstrates the lack of bone in the facial and apical aspects of the implant. The presence of frenum pulls (evident in Figure 1A from 1996) should have been a reason for concern. We believe that a prophylactic release of the frenum pull prior to implant loading would have prevented such outcome. Today, we would have addressed the frenum pull with a CO2 frenectomy prior to implant loading.

Figure 3: Occlusal view of a modern design implant Megagen AnyRidge® with its early maintenance of the buccal-lingual ridge form

Figure 2 demonstrates two single Brånemark implants placed nearly 15 years prior. Natural buccal and lingual narrowing of the alveolar ridge and high mucogingival junction combined with frenum pull could possibly contribute to the buccal gingival recession and, consequently, the implant failure. In this case, the patient could have benefited from the tissue tension release.

Figure 3 presents the occlusal view of a modern design Megagen AnyRidge® implant with its early maintenance of the buccolingual ridge form. In other words, the buccal frenum pull was prophylactically released to alleviate tissue tension and lower the risk of marginal tissue recession in the future. Figure 3 clearly demonstrates healthy gingival mucosa in the absence of any frenum pulls or tension.

This article identifies the tissue tension problem and demonstrates a quick, effective, and relatively painless concept to prophylactically address this issue with the adjunctive use of a 10.6 micron SuperPulse CO2 laser.

Sources of pull and tension High muscle attachment: Sometimes, muscle attachment extends onto the crest of the ridge, which results in a shallow vestibule. Such muscle attachment can create space inadequate for a substantial implant-supported denture (or any denture, for that matter). In addition, muscle fibers exert considerable tension on peri-implant mucosa, which may eventually result in gingival recession. In such cases, a simple vestibular extension procedure can solve the problem. Small penetration depth of the CO2 laser is important for the vestibular extension procedure because it affords the clinician precise control over the depth of incision.

Frenum pull: Frena are folds of mucous membrane containing fibrous connective tissue that attach lips and cheeks to the alveolar mucosa, the gingiva, and the underlying Volume 8 Number 5

facilitate the introduction of plaque into the peri-implant pocket14,24 and lead to gingival recession. The presence of adequate (approximately 4 mm) attached gingiva correlates with mucosal health and can help prevent inflammation in peri-implant tissues. Al-Sabbagh and Bhavsar24 pointed out that wide zone of attached peri-implant gingiva provides better gingival seal around the implant. Another study has shown the correlation between lack of attached gingiva and crestal bone loss of 2 mm or more.25 These findings lead many clinicians, the authors included, to believe that the creation of sufficient amount of attached gingiva around implants is important and can potentially prevent implant failure. Width of the attached gingiva may be increased by a local vestibuloplasty.

To summarize, tissue tension or pull due to a shallow vestibule (caused by high muscle attachment), dense frenum, or lack of keratinized/attached mucosa can contribute to gingival recession. In addition to causing an esthetic problem, mucosal recession that denudes threads or a rough implant surface might impede the ability of the patient to maintain the implant clean from plaque. The resulting inflammation and infection create the risk of potential peri-implant bone loss and eventual implant failure.26,27

Proposed solution In order to effectively release tension created either by a high muscle attachment and/or dense frenum, or high mucogingival junction with only a small amount of gingival mucosa, we recommend performing a CO2 laser frenectomy and/or vestibuloplasty with secondary epithelialization.

Why CO2 laser?

Not all lasers are equally efficient at both tissue vaporization (i.e., ablation or cutting) and coagulation. The difference is illustrated in the absorption spectra for main soft tissue chromophores28,29 in Figure 4. Some dental laser wavelengths (around 3,000 nm, such as Erbium lasers) are well absorbed by the water-rich soft tissue and are great at cutting but are not as efficient at coagulating.29 Other dental laser wavelengths (around 1,000 nm, such as diodes and Nd:YAG) are efficient coagulators, but inefficient scalpels30 since they are poorly absorbed by the soft tissue.

The 10,600 nm CO2 laser wavelength is efficient at both vaporizing and coagulating the soft tissue simultaneously (Figure 4), although it is not as good as Erbium laser at cutting and not as good as diode/Nd:YAG at coagulating. Most importantly, the CO2 laser’s Implant practice 27

This, coupled with frenum pull, may contribute to a buccal recession

periosteum.17 Some frenal attachments can be dense, pulling on the attached gingiva.

Tissue tension caused by the presence of frenum pull can be an important etiological factor in progressive gingival recession around posts and in eventual strut exposure.18,19 In the case of implant-retained denture prosthesis, frenum can limit denture extensions and even affect the seal and retention of the denture.18,20 The CO2 laser frenectomy procedure that releases tension exerted by the frenum pull creates a better chance of long-term success for a dental implant without sutures pulling, less postoperative swelling, and only minor pain or discomfort.

Lack of keratinized mucosa or attached gingival mucosa: Another risk factor is lack of attached gingiva. The width of attached gingival mucosa varies for different patients and even for different teeth in the same patient. In the oral cavity, attached gingiva (keratinized masticatory mucosa) meets movable alveolar mucosa (lining mucosa) at the mucogingival junction (MGJ). Clinically, the MGJ is identified by a mucogingival groove and the change from the pale pink of the attached gingiva to the bright pink of the movable alveolar mucosa.20 Width of keratinized mucosa is the distance between the mucogingival junction (MGJ) and the coronal aspect of the keratinized mucosa.14 There is no unequivocal consensus on the role the presence of keratinized mucosa plays in maintaining implant health.21-23 Literature suggests that a greater width of keratinized mucosa is advantageous due to the following: • It provides a resistant barrier to plaque-induced inflammation • It replaces non-keratinized margins to prevent recession • It deepens vestibules to provide better access for tooth brushing • It dissipates functional and masticatory stress placed on the gingival margin of a restoration • It facilitates oral hygiene, and improves esthetics and patient comfort14,16,22 Clinicians generally agree about the link between the insufficient amount of keratinized mucosa or attached gingiva and marginal tissue recession. A study by Chung, et al.,14 has found that dental implants with insufficient attached gingiva show more plaque accumulation and mucosal inflammation than implants with adequate attached gingiva. If attached gingiva is insufficient (less than 4 mm), and the MGJ is positioned high, mucosa surrounding the implant is mobile and easily retractable during mastication and speech.24 Such tissue retraction can

coagulation depth closely matches the blood capillary diameters,29 as illustrated in Figure 5.

Laser pulsing is also as important for laser surgery as the wavelength: the short and powerful pulses are often superior to long and weak ones. The exact physics of pulsed laser surgery deals with the Thermal Relaxation Time,29,30 which depends both on tissue’s light absorption and tissue’s thermal diffusivity, first described by Einstein32. The irradiated tissue is ablated (vaporized) the most efficiently when the pulse duration is much shorter than the Thermal Relaxation Time. The tissue adjacent to the ablated zone cools down most efficiently when the length of time between laser pulses significantly exceeds the Thermal Relaxation Time.

Such laser pulsing, referred to as SuperPulse, minimizes the depth of coagulation and is a must-have feature of any state-of-the-art soft tissue surgical CO2 laser.29 The optimal combination of the CO2 laser wavelength and pulsing allows for a char-free and bloodless surgery. This also allows for a scar-free, uncomplicated healing that is valued by surgeons across all specialties in dentistry, OMFS, ENT, plastic surgery, etc.

Laser beam spot size Just like the sharpness of the steel blade defines the quality and ease of the incision, the size of the laser beam focal spot determines the quality of the laser cut. The smaller (or sharper) the focal spot of the beam, the narrower and deeper the incision. Just like a dull blade cannot produce a quality incision, an oversized laser beam spot cannot produce a precise and narrow incision. For cutting, the LightScalpel laser handpiece is maintained 1-3 mm away from the tissue and is moved at a hand speed of a few millimeters per second — as illustrated in Figure 6. For a rapid switch from cutting to just photo-coagulation, the 28 Implant practice

laser beam can be defocused. Defocusing can be achieved either by selecting a larger spot size, or by simply moving the handpiece away from the tissue (by approximately 8 mm for LightScalpel tipless laser handpieces), and “painting” the “bleeder” for enhanced hemostasis (Figure 6).

Laser power density and depth of incision For a laser scalpel, the power density of the focused laser beam is equivalent to the mechanical pressure that is applied to a cold steel blade. In other words, greater laser fluence29 (i.e., greater power density and slower hand speed) results in greater depth and rate of soft tissue removal. During each SuperPulse pulse, the ablation depth δ is given by the formula δ = A (E – Eth) / Eth for the steady state ablation conditions,30 where A is the absorption depth from Figure 4 and Eth is the ablation threshold fluence,29 and E is the fluence during the SuperPulse pulse. At the 10.6 µm wavelength of the CO2 laser, the ablation threshold for a water-rich soft tissue with an assumed water content of 75% equals approximately Eth = 3 J/cm2.

For repetitive pulses that are scanned across the soft tissue, the fluence is defined by the pulse frequency and the hand speed: i.e., the depth of incision depends on laser power settings, spot size, and the surgeon’s hand speed33,34 (Figure 7).

Uses of CO2 lasers in implant dentistry CO2 lasers have been used and studied in many areas of implant dentistry.18,33-39 Some authors consider the newer CO2 lasers the most versatile of all the soft tissue lasers in implant dentistry.38 For example, the CO2 laser is effective for creating flaps, incisions for a sinus lift, stage II implant uncovering, treatment of peri-implantitis, removal of

gingival hyperplasia, epulis, fibromas, graft donor site hemostasis, and so on. The CO2 laser allows the clinician to address such critical aspects of implant therapy as the extraction site sterilization, excess cement removal, troughing for digital impression, and muscle pull release. All of the above is important for long-term success of implants.

Hemostasis: The CO2 laser’s excellent hemostasis and coagulation (due to close match between coagulation depth and gingival blood vessel diameters) allows to perform surgery even in the most vascularized areas. It affords the clinician improved visibility of the surgical field, and therefore, Volume 8 Number 5

allows for more precise and accurate tissue removal.40 Due to the efficient hemostasis, intraoral surgical wounds often do not require suturing or surgical dressing and can be left to heal by secondary intention.18,41 Minimal post-operative swelling: Another advantage of the CO2 laser is minimal postoperative swelling and edema due to the intraoperative closure of lymphatic vessels on the margins of the CO2 laser incision. Lymphatic vessels regenerate in approximately 8 to 10 days after capillaryvessel proliferation.42 Reduced post-operative pain and discomfort: Although it is generally difficult to evaluate pain, less discomfort was reported with the CO2 laser surgery than with conventional one.43 In the study by Niccoli-Filho, et al.,44 the patients reported minimal discomfort only during the first 24 hours after the CO2 laser surgery. Haytac and Ozcelic45 reviewed the use of the CO2 laser in frenectomies.

Based on patient pain perceptions during this procedure, they concluded that the laser treatment was less painful than the one performed conventionally, with a scalpel. In Neckel’s study46, vestibuloplasty was performed on 40 patients with either a conventional blade or with a CO2 laser. Both groups showed similar increase in the vestibular height, but patients in the CO2 laser group reported less pain and discomfort. Strauss, et al.,47 and Deppe, et al.,48 compared the recovery process following CO2 laser surgery with that following cryosurgery and electrosurgery and Volume 8 Number 5

Figure 11B: Second ISQ reading of the same implant driven to its intended depth

reported that with the CO2 laser healing was faster and less painful.

Laser healing and reduced scarring Significantly reduced wound contraction and scarring are among the most important advantages of CO2 laser treatment.41,49-51 In CO2 laser-irradiated wounds, the healing process is characterized by a more prominent fibroblastic proliferation, with young fibroblasts actively producing collagen.

Several studies51-53 found that in comparison with scalpel wounds, only a small number of myofibroblasts (cells responsible for wound contraction) are present in the CO2 laserexcised wounds. Seventy-two hours after the CO2 laser surgery, a fibroserous membrane forms over the wound to replace the superficial necrotic layer of the laser-irradiated site.54,55 Approximately 2 weeks postoperatively, the wound starts to epithelialize from the periphery toward the center. The epithelial covering of the laser wound is thinner and parakeratotic in comparison with the epithelium that forms after scalpel resection.

This could account for the superb esthetic outcome of CO2 laser surgery with smooth pliable new tissue and no fibrosis or scarring, while a scalpel can leave some scarring.50 Decreased wound contraction combined with minimal lateral tissue damage, less traumatic surgery, precise control over the depth of incision, and excellent hemostatic ability make the CO2 laser a safe and efficient alternative to a conventional scalpel.

Figure 10B: Anterior implant placed to the depth of 3 mm subgingivally by hand torque driver

To summarize, the physics of lasertissue interaction, the considerable amount of peer-reviewed literature on uses of the CO2 laser in implant dentistry, and our own clinical experience confirm our choice of the CO2 laser as the surgical tool for soft tissue tension release, frenectomies, and vestibular extensions.

Case study 1 A 75-year-old female patient presented for recurrent caries in the lower left premolars Nos. 20 and 21, underneath crowns (Figures 8A-8B). In addition, the teeth had weak coronal structure. Since they deemed unstable for long-term survival, it was decided to extract them and replace them with two single implants. Six weeks after extraction, the patient returned for a flapless implant placement (Figures 9-11B).

Six weeks after implant placement (the healing phase), the patient came in for the implant crowns loading. Figures 12A and 12B demonstrate healthy appearance of periimplant mucosa. However, horizontal rotation of the labial and buccal tissue revealed tension created by the movable mucosa very close to the implants. This was due to the narrow zone of attached gingival mucosa (this narrow zone is especially noticeable in Figures 10B, 11A, and 12A. The pale pink tissue is the attached gingiva, whereas the bright pink is the movable alveolar mucosa).

It became apparent that the encroaching movable mucosa and the close buccal frenum insertion (clearly seen in Figure 8A), both exerted tension on the peri-implant tissue, especially noticeable when lip or cheek were manipulated. This created potential for tissue recession and could eventually facilitate the implants’ failure. It was decided to perform a CO2 laser frenectomy/vestibuloplasty to alleviate the tension and possibly increase the width of attached gingiva.

SEEING THE LIGHT Surgical Laser Equipment: A flexiblefiber dental CO2 laser LightScalpel LS-1005 was utilized with a dental angled tipless handpiece with a 0.25-mm focal spot diameter Laser Settings: 3 watts; SuperPulse Repeat Pulse Mode F1-6 Anesthesia: No local anesthesia was administered; only topical was used. (With some patients local anesthesia is given.)

CO2 laser procedure: Traction was applied labially and buccally to expose the tissue tension between the keratinized gingival mucosa and movable alveolar mucosa as well as the frenum pull. Importantly, maintaining traction significantly facilitates laser cutting.

A horizontal CO2 laser incision was made along the mucogingival junction (or the line where the tension is most apparent) following the contours of the underlying bone. The tip of the laser handpiece was held perpendicular to the target tissue at a distance of 1 mm–2 mm from it. The handpiece was moved at the recommended speed of 4-5 mm/second. While making the laser incision, the clinician feels the release of the tissue tension. If the created incision, however, does not provide satisfactory tension relief, additional passes may be needed. Typically, between 4 and 8 laser passes are made to achieve the desired depth of incision, and the procedure usually takes under 1 minute.

Normally, the CO2 laser produces excellent visualization and a clear operatory field (Figure 12C). If, however, slight bleeding occurs after the incision is made, the laser beam is defocused by increasing the nozzle-to-tissue distance to quickly obtain hemostasis.

Wound closure: No suturing was used after this procedure. The wound was left to heal by secondary intension. Generally, the wound re-epithelializes within 2.5-3 weeks.

Postoperative instructions: The patient was released from the clinic with instructions to do warm salt water rinses 4 times a day and to apply topical antibiotic and vitamin E gel twice daily directly to the area. The patient was advised to avoid spicy, acidic, or harsh foods with sharp edges, or caustic mouth rinses. She was educated about the maintenance of oral hygiene. The patient reported to be completely pain-free 24 hours after the surgery.

Follow-up examination: Two weeks after the procedure, the patient returned for a check-up. Healing progressed well. No signs of swelling or inflammation were noted.

The patient did not express any complaints during the postoperative period. The 4-week follow-up visit showed beautifully healed tissue with no scarring (Figures 13A and 13B). The recovery was uneventful. Figures 14A and 14B present the buccal final view 30 Implant practice

10. Patient is released from the clinic immediately after the procedure with instructions on how to maintain oral hygiene, to avoid acidic, caustic or harsh foods, drinks or mouth rinses.

We recommend warm salt rinses 4 times a day; NSAIDs, if needed, topical antibiotic and vitamin E gel twice daily.

Figure 16 demonstrates immediate postoperative view of the CO2 laser frenectomy/vestibuloplasty completed in less than 1 minute, bloodlessly, and without local anesthesia.

Follow-up evaluation: At 4 weeks, the surgical site appeared completely healed (Figure 17). The patient gained 3 mm-4 mm of the vestibule depth, and although the frenum was still present, its attachment moved apically and further away from the implant (Figure 17).

Conclusion The CO2 laser was chosen for this procedure for several reasons, such as the laser’s ability to provide instant hemostasis with a minuscule zone of thermal injury (sub 50 microns),31 lack of need for sutures, reduced wound contraction, smooth healing, and only minor pain and discomfort reported by patients.

The CO2 laser frenectomy/vestibuloplasty is a simple, neat, and quick procedure with minimal postoperative pain or discomfort for the patient. While by no means a panacea against implant failure, this procedure allows the clinician to remove one of the many risk factors — i.e., tissue tension, that can potentially compromise the long-term success of dental implants. Due to the above and based on years of clinical experience, the authors recommend the CO2 laser frenectomy/vestibuloplasty as an effective surgical solution. IP

Ridge preservation in a case of severe periodontitis Drs. Roberto Rossi, Ulf Nannmark, Andrea Pilloni, and Nino Squadrito, CDT, demonstrate how to preserve and condition the soft tissue with a combined approach

P

eriodontal disease is often responsible for the loss of attachment around teeth and therefore a major cause of ridge deficiency after the teeth are extracted. The world has become more and more aware of esthetics in dentistry, and any procedure aimed to preserve the hard and soft tissue becomes useful to satisfy the needs of increasingly demanding patients.

This article will present a case of advanced periodontitis treated with a ridge preservation technique and later planned and finalized with the use of guided implant surgery, immediate loading, and thus, soft tissue conditioning in order to minimize the effects of the disease.

The literature Tooth loss in many cases is one of the primary causes of alveolar bone remodeling and loss. Schropp and colleagues showed the changes in the soft and hard tissues after teeth extraction in clinical and radiographic prospective study (2003).

The tissue changes after removal of a premolar or a molar in 46 patients were evaluated over a period of 12 months by measuring study casts, linear radiographic analysis, and subtraction radiography. Their results showed that the major changes occurred during 1 year after extraction.

Jahangiri and colleagues reviewed the understanding of the biology of tooth extraction, wound healing, and residual ridge remodeling (1988). Defects in socket matrix formation or cellular activity will lead to stalled healing. The review of residual ridge remodeling describes the long-term result of tooth extraction and formation of

Educational aims and objectives

This article aims to present a case of advanced periodontitis treated with implants and a ridge preservation technique to help preserve and improve the soft tissue.

Expected outcomes

Implant Practice US subscribers can answer the CE questions on page 40 to earn 2 hours of CE from reading this article. Correctly answering the questions will demonstrate the reader can: • Identify a technique for approaching implant treatment in severe periodontitis in order to minimize the collapse of the soft and hard tissue and thus try to preserve the natural esthetics.

• Review the biology of tooth extractions, wound healing, and residual ridge modeling.

• See how this technique with the materials used limited contour changes after tooth extraction and preserved facial keratinized gingiva.

• Realize the differences in the pattern of bone resorption in periodontitis and non-periodontitis subjects.

• Recognize that the combination of presurgical computed planning and immediate loading might lead to excellent soft tissue conditioning and minimal surgical traumatism for the hard and soft tissue.

• Realize the importance of the relationship between the height of the interproximal bone peak and the teeth’s contact point to emphasize the importance of maintenance or reconstruction of the bone to support the soft tissue.

residual ridges in which the quantity of bone tissue continuously decreases. The authors suggested that any potential regulatory factor of residual ridge resorption should have an adverse effect either on the increased catabolic activity by osteoclasts or on the decreased anabolic activity by osteoblasts.

A recent study by Barone and colleagues described the tissue changes of extraction sockets with a comparison of spontaneous healing versus a ridge preservation technique with secondary soft tissue healing (2013).

The study group was treated with careful extraction and insertion of corticocancellous porcine bone and a collagen membrane, while the control sites received only sutures to stabilize the blood clot. Test sites showed a vertical bone remodeling of 0.3 ± 0.76 mm, 1.1 ± 0.96 mm, and 0.9 ± 0.98 mm at the mesial, buccal, and distal sites, while the control group showed a remodeling of 1 ± 0.7 mm, 2.1 ± 0.6 mm, and 1 ± 0.8 mm at the same sites. Horizontal changes were 3.6 ± 0.72 mm in the control sites and 1.6 ± 0.55 mm in the study group.

This study concluded that alveolar ridge preservation technique performed with collagenated porcine bone graft and a resorbable membrane was able to limit the contour changes after tooth extraction.

Another important issue was that test sites

showed a better preservation of facial keratinized gingiva when compared to control sites. Also, grafted sites allowed the placement of longer implants and wider implants when compared to non-grafted sites.

In 2008, Allegrini and colleagues reviewed the literature on socket preservation and concluded that the maintenance of the alveolar bone after extraction depends on a careful surgical procedure and the use of a biomaterial capable of maintaining the prior space, which is helpful in bone tissue healing.

In 2012, Lindhe and colleagues evaluated an important factor: changes in the pattern of bone resorption in periodontitis and nonperiodontitis subjects. The paper was to discuss the tissue of the fully healed extraction sites in patients who had lost teeth as a result of periodontal disease or from other causes. This study indicated that the edentulous posterior maxilla was comprised of 58% lamellar bone, 15% woven bone, 7% osteoid, and 10% bone marrow. More than 50% was mineralized bone. Also, Vignoletti and colleagues presented a systematic review of the surgical protocols for ridge preservation after tooth extraction (2012).

Fourteen publications on PubMed, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) were evaluated, each looking at randomized controlled Volume 8 Number 5

clinical trials and prospective cohort studies with a follow-up of at least 3 months reporting on changes on both the hard and soft tissue (height and width) of the alveolar process (mm or %) after tooth extraction (up to February 2012). Data from nine of these 14 studies were grouped in the meta-analysis.

The results showed a statistically significant greater ridge reduction in bone height for control groups as compared to test groups and a significant greater reduction in bone width for control groups.

The authors concluded that the potential benefit of socket preservation therapies is demonstrated in less vertical and horizontal resorption of the alveolar bone crest. The scientific evidence does not provide clear guidelines in regard to the type of biomaterial, or surgical procedure, although a significant positive effect of the flapped surgery was observed. After the ridge preservation has been performed, a study suggested a protocol for planning and treating such cases with guided implant surgery (Rossi, et al., 2010).

The authors showed how the combination of presurgical computed planning and immediate loading might lead to excellent Volume 8 Number 5

shows pockets up to 12 mm on the first bicuspid, 8 mm on the distal of the second bicuspid, and 9 mm and 10 mm on the mesial and distal of the first molar. The teeth were healthy and did not have any cavities (Figures 2-3). Bone loss was reaching around the apex of the roots of the first bicuspid and the first molar, and the mobility was 2+.

Local anesthesia is first administered with a computerized controlled device (Single Tooth Anesthesia, STA™, Milestone Scientific, Inc.) with articaine with epinephrine 1:200.000.

Once the teeth and the surrounding soft tissue were anesthetized, the teeth were separated from the gingiva with a microblade and later extracted (Figure 4). The granulation

CONTINUING EDUCATION tissue on the extraction sockets was carefully curetted, and the sockets were first irrigated with chlorhexidine and later grafted with corticocancellous collagenated porcine bone graft (Figure 5) (mp3, OsteobiolÂŽ).

The periapical radiograph shows the attempt to completely fill up the residual sockets (Figure 6). The simultaneous application of a removable partial denture (Figures 7-8) with ovatic pontics had the goals of, first, sealing the grafted sockets and, second, supporting the soft tissue in an attempt to preserve a scalloped gingival architecture.

The re-evaluation at 8 months (Figure 9) shows how the temporary denture helped guide the healing, protecting the bone grafts and also maintaining the natural scalloped architecture.

At this point, the case was studied with a navigation system (OsstemGuide™, Hiossen Osstem), and the treatment plan was to place three dental implants in place of the roots of the teeth previously removed. The case analysis shows how the ridge preservation

and integration of the bone grafts allowed the placement of three implants of 5 mm diameter (Figures 10-13).

The surgical guide was created using computer technology and verified prior to the surgical appointment. On the day of surgery, the protocol calls for stabilization of the surgical guide on the residual teeth but with some flow composite on the upper right canine. The width of the crest was maintained after extractions and with a ridge

Figure 20 shows part of the previous section at a higher magnification (X20).

the right upper corner, a small piece of biomaterial is totally surrounded by bone. No signs of inflammation can be seen in the soft or hard tissue (Figures 19-20).

The surgical trauma was very minimal, and the possibility to install a temporary bridge on the implants on the same day further enhanced the chances of conditioning the peri-implant soft tissue (Figure 21). The post-surgical X-ray shows the precision and the perfect abutment to implant connection. Six months later in a follow-up visit, the

Conclusion Esthetics are becoming more and more important in modern dentistry, and the preservation of the soft and hard tissue is one of the primary goals. Any time we ran into cases of advanced or aggressive periodontitis where the bone loss and the PSR was four, we noticed a severe collapse of the soft tissue as a consequence of the advanced bone loss.

Since dentistry is moving forward into esthetics, a protocol that will help restore the hard tissue in cases of aggressive periodontitis will also help in the preservation and improvement of the soft tissue, giving clinicians a new therapeutic option. IP

Modern periodontal and implant literature became very aware of this problem, and many different techniques have been introduced to solve and minimize this problem (Jahangiri, et al., 1988; Allegrini, et al., 2008; Lindhe, et al., 2012; Vignoletti, et al., 2012; Ladsberg and Bichacho, 1994; Kutkut, Andreana, and Monaco, 2012).

Many different authors have presented similar protocols with different biomaterials, from autogenous bone, to allografts, to synthetic and xenografts, but all of these procedures, despite using different materials, share a similar goal of minimizing the collapse of the soft and hard tissue and thus trying to preserve the natural esthetics (Horowitz, Holtzclaw, and Rosen, 2012; Horvath, et al., 2013; Scheyer, Schupbach, and McGuire, 2012; Pagni, et al., 2012; Cardaropoli, et al., 2012; Hämmerle, et al., 2012).

The relationship between the height of the interproximal bone peak and the teeth’s contact point has been well described in the literature (Nordland and Tarnow, 1988); therefore, the maintenance or reconstruction of the bone in that area becomes of paramount importance in supporting the soft tissue and, thus, esthetics. A combination of ridge preservation techniques with subsequent guided implant surgery will reduce the surgical trauma to the soft tissue, help condition the interproximal

Drs. Lira Rahman, Jacobus Hercules van den Heever, and Andre W. van Zyl present the application of guided dental implant surgery in prevention of inferior alveolar nerve damage in a patient with compromised bone Introduction Iatrogenic injuries to the inferior alveolar nerve (IAN) can impact significantly on patients’ lives. Altered sensation and pain in the orofacial region may interfere with speaking, eating, kissing, shaving, applying makeup, tooth brushing, drinking, and just about every social interaction (Renton, 2010).

IAN injury is the most problematic consequence of dental surgical procedures and has major medico-legal implications (Renton, 2011).

Causes of inferior alveolar nerve injury include placement of dental implants, local anesthetic injections, third molar surgery, endodontics, trauma, and orthognathic surgery.

Educational aims and objectives

This article aims to present the application of guided dental implant surgery in prevention of inferior alveolar nerve damage in a patient with compromised bone.

Expected outcomes

Implant Practice US subscribers can answer the CE questions on page 43 to earn 2 hours of CE from reading this article. Correctly answering the questions will demonstrate the reader can: • Identify some symptoms of inferior alveolar nerve (IAN) damage.

• Recognize some causes of IAN. • See a case where IAN was prevented.

• Realize the benefit of the surgical guide in planning the case.

Case history A healthy 53-year-old female patient presented with a collapsed occlusion. Her main complaints were difficulty in chewing, esthetic dissatisfaction, and a desire not to lose more teeth. Function was limited to the seven anterior teeth with no posterior support (Figures 1-3). Loss of posterior occlusion may result in the loss of neuromuscular stability of the mandible, temporomandibular joint (TMJ) dysfunction, reduced masticatory efficiency, loss of vertical dimension, and poor esthetics. Rehabilitation should aim to address all of these concerns.

Further complications were lack of attached keratinized tissues and reduced mandibular alveolar ridge volume. Keratinized attached tissue, although a contentious topic, may have long-term benefits

was planned that the implants would need to be angled toward the lingual cortex to avoid the mental foramina and the inferior alveolar nerve (IAN). It was anticipated that angling the implant lingually in a controlled manner would result in a slight deviation of the implant toward the buccal direction.

The implication of this is that the surgeon requires a guide with a degree of “play,” which will allow him/her to make corrections during surgical placement of the implants.

The lack of attached keratinized tissue was addressed by performing bilateral mandibular vestibuloplasty procedures and free gingival grafts.

Straumann® Roxolid® Tissue Level Implants were placed with a 2-mm safety zone between implant and nerve (Greestein and Tarnow, 2006). Two 3.3 mm x 10 mm implants were inserted in the LL5 and LR5 sites and two 3.3 mm x 8 mm implants in the LL6 and LR6 sites using the Classic SurgiGuide. Roxolid is 50% stronger than pure titanium and shows improved integration with bone and is thus ideally suited for reduced bone situations (www.straumann. us, 2008).

Provisional implant supported crowns are shown in Figure 5. Maxillary implants were subsequently inserted as planned (Figure 6).

No postoperative nerve fallout or complications were experienced.

Five foolproof ways to get a “yes” to more treatment plans

Dee Dee Reid discusses ways to help patients get the dental care they need

L

et’s face it, no one likes to hear the word “no.” But the reality is, despite the economic upturn, patients are still reluctant to say “yes” to larger treatment plans. A 2014 American Dental Association (ADA) study found that 40% of adults indicated that they will forgo dental care due to cost.1 Clearly, a healthy mouth shouldn’t be an “either/or” proposition for patients, but no one wants to be a pushy salesperson either.

So what can you do?

For over 20 years, I’ve helped dental practices from Texas to California realize profitable growth. The key to getting higher acceptance rates lies in how your office approaches the treatment plan presentation. Try using these five proven techniques, and you’ll have more patients saying “yes.”

1. Listen and learn Did your last case presentation seem a little one-sided? Was the patient nodding as you talked, but then at the end of the

Dee Dee Reid has focused her 20-plus year career in dentistry, and her experience spans the spectrum of care. Ms. Reid began her career in the back office where she gained a deep understanding of clinical details and practice dynamics. She connects with patients as a top-producing patient care coordinator. Ms. Reid helps doctors explain and schedule large cases and works alongside general dentists, dental specialists, and their teams to advance practice goals and get results. Most recently, she was a guest lecturer and workshop coordinator for the Functional Aesthetics series with Dr. Mark Montgomery and Dr. David Hornbrook. She frequently leads team programs for Contemporary Products Solutions related to team development for Invisalign® office systems. She has iTunes® podcasts available from the Thriving Dentist Show with Gary Takacs (The Relationship-Driven Practice) and from Dental Up with Dr. David Hornbrook (Increasing Your Practice Exponentially).

exam, he/she just left without committing to the procedure? The problem starts with the communication technique. Often, patients don’t fully comprehend what you’re proposing and how they can afford to pay for it. Remember, it’s hard to focus on anything when your mouth is full of equipment.

I recommend to my clients that they modify their consultation process. Start by conducting the usual exam, but pause before delivering the prognosis. Ask patients what’s important to them. Ask about their goals and their overall health, not just their oral health.

Ask if they are happy with their appearance and their confidence level when they smile.

Then, just listen. Let patients tell you what they are feeling.

Performing this simple step will provide valuable tips on how to position your treatment plan in a way that directly aligns with the patient’s personal goals. Discuss “why” and “how” your treatment plan addresses their concerns. Avoid simply listing “what” Volume 8 Number 5

PRACTICE DEVELOPMENT you’re going to do (too much procedural or technical information can be off-putting). This active listening technique is far more collaborative. When patients feel understood, it naturally follows that they are more likely to say “yes” to the treatment plan you’ve developed together.

2. Show, don’t just tell Showing your patients what’s going on inside their mouth is a lot more powerful than simply telling them. That’s why I strongly recommend using intraoral digital photography during the diagnostic phase. Pointing to a problem area with a digital image makes any issue become immediately clear.

Remember, for most patients, if it doesn’t hurt, it isn’t a problem. That’s because patients see only what’s in the bathroom mirror. Once patients see full-mouth photography, it’s so much easier to have a constructive dialogue. Showing patients a photo of their own dental issue lets them understand the need for even the most preemptive of treatment plans.

3. Success takes teamwork No matter how hardworking or talented, every dentist needs a good support team.

That’s why (if you don’t already have one), I strongly recommend creating the position of Patient Coordinator. I’ve also seen this role called “Patient Care Counselor,” “Patient Procedure Manager,” or as in my case, “Patient Concierge”— but call it what you like, this position is key. You see, once the dentist has defined the treatment plan, it’s the Coordinator who works out the details with the patient.

I’ve found many patients are more comfortable talking to the Coordinators.

That’s because they can use layperson’s terms to review procedures, insurance coverage, and the ease of third-party financing options. For many patients, how to pay is just as important as understanding what they’re paying for. Patients also like that Coordinators understand the need for affordability and financing options. Ultimately, a good Coordinator can make all the difference in closing the case.

But what about the cost of this new position? The good news is that adding a skilled Treatment Coordinator can pay for itself. Here’s the math: A skilled Coordinator will cost between $3,500-$5,000 per month (depending on where your practice is located).

But that same Coordinator can schedule and close an average of $2,000-$5,000 per day.

Plus, the increase in practice collections is 46 Implant practice

The key to getting higher acceptance rates lies in how your office approaches the treatment plan presentation. often between $25,000-$75,000 per month.

All this while freeing up the clinical team and the doctor to do what they do best — procedures. Now that’s a healthy ROI!

4. Educate everyone, not just the patient Clearly, creating a Patient Coordinator position is important. But I reinforce with my clients the need to educate the entire support staff on frequently performed procedures, treatment schedules, common medical terms, financing option details, and practice protocols. That way, no matter who interacts with the patient, the conversation is seamless.

As a practice becomes more successful (and everyone becomes busier), an officewide communication strategy is essential.

This can be accomplished a number of ways: weekly staff meetings, office-wide emails or memos, even a company newsletter.

It’s your choice, just as long as everyone is kept up-to-date on important practice developments.

5. Make it easy to say “yes” I started this story with news of an ADA study. The fact is that over 40% of adults are still concerned about paying for dental care. Clearly, ease of obtaining affordable financing is an important factor for getting patients to say “yes.”

Many doctors don’t feel comfortable talking about money — but I always discuss third-party financing with patients. I also recommend my D2 Coaching and Consulting clients do the same. You see, as Concierge, it’s my job to make it as easy as possible for the patient to say “yes” to the doctor’s treatment plan. That’s why I love working with Lending Club Patient Solutions (formerly Springstone Patient Financing).

Honestly, they’re great partners. I’ve worked with Lending Club Patient Solutions for over 8 years now because they do an amazing job of empowering patients with more responsible and convenient financing options. Patients get what they want: fast approvals, True No-Interest Plans2 that avoid unwelcome surprises, and Extended Plans with great rates for low monthly payments.

Your practice gets convenient selling tools,

helpful email updates with the patient’s funding status, five-star customer service, and some of the lowest practice fees in the industry.

Some dental practices do still use selffunded patient financing. But the half-now/ half-later business can be a recipe for disaster. No one wants to have the tough “your payment is late” conversation — after all, you’re not in the debt collection business.

With a good financing partner, you can avoid all of that. Their no-default risk means the office receives payment upfront, so collections never cross your mind. Plus, working with an exceptional vendor like Lending Club Patient Solutions says a lot for your practice’s reputation and helps you build lasting patient relationships to grow your business.

You can find out more about Lending Club Patient Solutions at lendingclub.com/ providers.

Time to put the steps into practice Naturally, there are lots of ways to help patients get the dental care they need and the services they want. But I hope you’ve found the tips I’ve covered here helpful, including honing your listening skills, using visuals, adding the role of Patient Coordinator, and recommending patient-friendly financing like plans offered through Lending Club Patient Solutions.

Imagine how successful your practice would be if just 50% more of your patients actually scheduled a procedure after their consultation? This type of conversion rate is possible when you follow these five easy steps. IP REFERENCES 1. Yarbrough C, Nasseh K, Vujicic M. Why adults forgo dental care: evidence from a new national survey.

hat target market do you currently attract — and why do you attract it?

This question should hopefully make you think of the current effect of your past marketing efforts. The simple fact is that the leads and patients you attract are a direct reflection of the target market you choose to focus on.

To answer this question — and many others related to your marketing activities, I am going to use a tool that I call the “triple M” profitable marketing framework. This framework is about getting the right message to the right market using the right media and methods effectively, efficiently, and profitably. It can help you to simplify, understand, and apply the essence of what profitable marketing really is.

The power of three To fully understand the market you currently attract, there is a simple, but extremely valuable, exercise you can do.

Create a project to review your patient database going back as far as you can, and group all your patients into three distinct categories: 1. Best patients 2. Average patients 3. Worst patients You should have your own criteria for deciding what constitutes the definition of patients in each category, but you may wish to consider the following.

Your “best patients” category should consist of people you really love to see for one reason or another; typically they will be the most profitable patients your practice has.

The “average patients” will be just that — they are not the most profitable, but they are probably loyal, relatively easy to treat

and satisfy with minimum stress to you and your team.

The “worst patients” are the ones that give you headaches — I am sure some may come to mind already. They are the ones that are regularly late for appointments, thereby messing up your work schedule. They regularly complain about your prices, staff, or services. You actually dread treating these patients as you have come to realize they are just very difficult to satisfy.

Nurturing patients Having done this exercise, I would urge you to nurture all the best patients you can identify. Make them feel special in all interactions with your practice; explore the many ways you can provide more value to them while also extracting more revenue from the relationship. You will generate the most revenue from this group directly and subsequently from their referrals, assuming your practice has the appropriate referralgenerating systems in place.

Study the average patients carefully; seek to understand them better as there is a good chance of converting between 10% and 40% of them to your best patient category, depending on their profiles and the marketing strategies you deploy to this effect.

Most of them will, however, remain average patients, so you need to make sure they are profitable, reliable, and to keep them loyal to your practice for as long as possible.

There are a number of patient retention strategies you should seek to deploy in this regard.

With the group you identify as your “worst patients,” you should realistically consider “firing” as many of them as you can, as soon as possible. While this may sound somewhat harsh, you should realize it’s most likely the best thing you can do for your practice; you will save money, time, and improve team morale in the long term. In the short term, however, you should try to understand why

they are in the worst patient category and convert those that have similar profiles as your perfect patients. There are a number of ways to do this, but really, you should be sure they are worth this effort, hence the need to limit the exercise only to the ones that match your perfect patient profile.

Please understand that the process of categorizing your existing patients is very important and a necessary part of fully understanding who you have been attracting with your existing marketing. You can actually do this yourself; you can delegate it to your practice manager or get a consultant to help you with the process. How you do it doesn’t really matter, but it is something you simply must do if you are serious about creating a thriving dental practice.

With a good understanding of your current patient base, we should explore creating a profile of who you really want to attract as a patient moving forward. The previous exercise will be quite helpful as you should have observed some trends among the best patients you have already identified.

This next exercise requires you to think in futuristic terms and develop a crystal-clear profile, or what I call the “perfect patient avatar,” a detailed description of the ideal patient you want to attract to your practice.

Having identified the best patients you currently have, the next step is to describe what a perfect patient would look like to you.

How much do they earn? How old are they?

Are they married or single? What do they do for a living? How important is their appearance to them? What car do they drive?

Where do they go on holiday? What party do they vote for? These questions are to give you a general idea of how much you need to know about your perfect patients in order to attract them effortlessly to your practice.

The simple goal here is to develop an avatar — a profile that describes a very clear picture of who you really want as perfect patients for your practice. You will need to Volume 8 Number 5

Demographics With demographics you are able to describe people by groups that they belong to. This may range from gender, age, ethnicity, disabilities, mobility, home ownership, employment, status, location, and even sexuality. For example, will your perfect patient be in the age range of 25-35, 35-45, 45-55, or 55-plus? Will your perfect patient be male or female? Will he/she be a self-employed tycoon, a high-ranking executive, or a celebrity?

Psychographics On the other hand, psychographics helps you describe the interests, opinions,

Prosthetic Materials & Solutions

The perfect patient avatar To help create profiles of your ideal patients, ask yourself: • Are they male or female?

• How old are they?

• What is their marital status?

• How do they earn a living?

• Do they value their appearance?

• What car do they drive?

• What opinions do they have about politics, religion, and money?

• Where do they go on holiday?

attitudes, values, and behavior of your perfect patients. What are their likes and dislikes? What are their opinions on politics, religion, and money? What is their attitude about health and lifestyle?

The key to your success here is the ability to describe your perfect patient in as much detail as possible. Your whole team should be crystal clear on whom exactly you are looking for as a potential perfect patient.

Marketing foundation If you haven’t created a perfect patient avatar for your practice before, get one developed as soon as possible. If you have one already, now may be a good time to review it and establish if it is still ideal for your practice. Getting this right is critical, as it is the foundation on which you can build the marketing strategy of a thriving dental practice. IP

The other side to this is that with such a detailed understanding of whom you are looking for, identifying them and locating them becomes relatively easier in terms of your lead generation advertising. For example, if your perfect patient is a BMW-driving corporate executive, it’s relatively easy to locate all the corporate executives with a BMW in the country for a laser-targeted marketing campaign. A perfect patient avatar will also help make your referrals more profitable, as people tend to know people who are similar to themselves professionally and financially.

hen placing implants, choosing the right method of component retention can be a complicated decision. Whether you choose screw-, friction-, or cementretention, each method has great strengths and weaknesses; therefore, your selection should be made in accordance with each individual clinical situation.

Retrievability, stress, esthetics, and accessibility are just a few of the elements that enter the equation of suitability for optimal implant placement, as the clinical success of the restoration can be significantly influenced by your choice.

As an implant dentist,

Strengths and weaknesses

I am frequently asked

Over the years, the formula for the ideal method of restoration has divided opinion among dental implantologists, many of whom have a strong preference for a single particular method. These preferences have been known to change depending on current trends, what we read and, of course, the failures we may have experienced in the past.

The truth is, screw-, cement-, and friction-retained implants have many both pros and cons, and while some may be considered to be more advantageous, certain methods may be more appropriate than others in specific circumstances.

For example, while cement retention is often considered to be the most successful method by reducing stress in the restoration and bone, there are still certain disadvantages to this technique. Cement retention, for example, can cause issues Peter Sanders, FFGDP RCS (Eng), MSc ImpDent (Lond), DipImpDent RCS (Eng) (Advanced certificate), MFGDP, BDS, LDSRCS, has been placing and replacing implants since 1987.

For the past 8 years, his practice in Southampton has focused solely on implant dentistry. He completed the implant diploma at the Royal College of Surgeons in 2005 and obtained an MSc in implantology in 2009. He was awarded the fellowship by the FGDP RCS in 2011. He is currently a course director for the implant diploma at the Royal College of Surgeons in London and prior to this acted as an examiner for the diploma.

which is the best method of post retention. My answer is always the same: No single method is superior to another.

that occur with excess cement application leading to bone loss and peri-implant disease — particularly if standard components place the restorative margin deeper than would be ideal. Debonding — which can lead to the repeated loosening of the prosthesis and patient dissatisfaction — using a permanent cement may reduce debonding episodes but makes recovery more difficult or impossible.

Screw-retained implants also present disadvantages in certain cases; achieving a passive fit is significantly more difficult to attain with a screw-retained restoration due to stress being introduced into the restoration through the tightening of screws. If,

however, the prosthesis is cemented, a thin layer of the cement will offset a level of the stress offering compensation for any minor discrepancies in the fit, which would ordinarily contribute to lack of passivity. So, cement-retained restorations are more likely to reduce stress and therefore the likelihood of stress related implant failure or periimplantitis. Nonetheless, if retrievability is a factor that must be considered, then the likelihood of damaging the crown or bridge during removal is extremely high; a soft or temporary cement can be used if removal is necessary, but if frequent access is required, it is not the best method of retention.

IMPLANT INSIGHTS Friction-retained implant systems (where the abutment and/or prosthesis are retained by the force of friction between components) can provide a high level of stability and allow for a tension-free fit, without cement — this method has many advantages when it comes to ease of handling, use, and retrieval.

However, friction retention can also have disadvantages in certain circumstances. If the friction-retained prosthesis is designed to be removable by the patient, then the age or the dexterity of the patient should always be considered. If (for this or any other reason) the patient has ongoing issues with removing the retained prosthesis for hygiene reasons, it then becomes a de facto fixed restoration and will, therefore, need to be redesigned accordingly to facilitate oral hygiene procedures.

Retrievability Many clinicians consider screw-retained implants to be the most effective solution if easy removal or access is a requirement.

Retrievability is an important factor if the patient requires assistance with hygiene, or if the crown is fractured and needs to be repaired. However, while screw-retained implants can be easily accessed and removed, there is a risk that stress-related tension on the superstructure may be caused when re-tightening the screws in the process of replacement.

In terms of retrievability in cementretained implants, one of the most commonly cited disadvantages is the difficulty in removal of the prosthesis. If the patient requires a great deal of hygienic maintenance, or has a personal preference to be able to easily remove the superstructure to clean the prosthesis, friction-retained implants allow for this kind of access. Using a milled bar with a milled superstructure and by using tight angles (of around 4 degrees), the superstructure will gain retention through the friction applied to the bar. This will allow for the patient to easily access and remove the structure to aid the cleaning process.

One of the biggest advantages of the friction-retained implant prosthesis is that, if the patient has maxillary atrophy and therefore requires volume in the super-structure to deliver soft tissue or lip support, this tissue can be built, providing a more secure placement. If the superstructure is fixed, excess tissue support would normally be avoided due to the fact that the patient would not 52 Implant practice

be able to efficiently clean it. With frictionretained implants, the gums can be overlapped and cleaned with ease.

Esthetics: screw versus cement While the screw system may have advanced over many years, it is still at a disadvantage when it comes to esthetic results. With an implant angled to optimize bone availability and a system that allows only screw retention in line with the implant, the access hole in the prosthesis needs to be filled, and therefore, the esthetics of the crown are compromised from the outset. In addition, the hole filled in the prosthesis may also deteriorate over time.

Clearly, this is more of an issue in the esthetic zone at the front of the mouth where the flared maxilla inevitably results in the extension of the implant axis emerging through the facial surface of the crown.

To overcome this, an angled abutment is screwed into the implant and the crown, and then cemented. The cementation of the implant restoration eliminates the unsightly screw holes, resulting in a much more esthetically pleasing result.

Often, in order to achieve optimum results, combining methods of retention can be most effective. For example, systems such as ANKYLOS® SynCone® (Dentsply Implants) combine the use of screws and friction to provide a tension-free retention with optimum hygiene capability. With such systems, 4-, 5or 6-degree tapers are used, and here, gold caps are locked on to the abutments. These components are connected in the mouth to ensure passivity, but removal of the prosthesis for daily cleaning can be a challenge for less dexterous elderly patients.

Intraoral welding is also a technique that uses a combination of friction- or screwretention methods. Here, the abutments are connected to the implants and matching screw- or friction-retained components are tapped on to these. A titanium bar is then welded to these welding components while in the patient’s mouth. This means the fit is completely accurate from the outset,

and a more passive, stress-free structure is created.

With intraoral welding, friction components, which are inherently less bulky and easier to fit in the prosthetic envelope, are used around the front area of the mouth. The emergence of unsightly screw holes is also avoided. Farther back in the mouth, where more space is available, screw retention is used, giving the superstructure excellent stability.

Such combinations of retention are ideal if a patient has a fixed restoration but wants the benefits of having smaller volume components that provide friction retention toward the front of the mouth in the esthetic zone. Screws can then be used to lock the superstructure down in an area where there is space, and therefore, the esthetics of the prosthesis are not compromised.

Finding the right solution As an implant dentist, I am frequently asked which is the best method of post retention. My answer is always the same: No single method is superior to another. A well-experienced and adept implant dentist will understand the features, benefits, and risks of each of the methods of retention, and will apply the most suitable method (or combination of methods) to meet each patient’s specific requirements.

For example, there may be functional and occlusal considerations; lip support and bone volume may need to be considered, as well as the space available for each patient.

You may need to consider where the bone is best in relation to the prosthetic envelope, what angles you have to compensate for, and what the patient’s capacities are for hygiene and maintenance.

These all factor into whether screw-, cement-, or friction-retained implants should be selected for optimum placement. Having a broad knowledge and understanding of all three methods will enable you to provide a treatment plan that specifically suits your patient, ensuring successful long-term results are achieved.

Traditional Drill Bits Extract and Diminish Bone Replace Your Bits with Burs One by One

The Densah® Bur is based on a new technology for osteotomy preparation that we have called “osseodensification”. Unlike traditional bone drilling technologies, osseodensification does not excavate bone tissue. Rather, it preserves bone bulk so bone tissue is simultaneously compacted and auto-grafted in an outwardly expanding direction to form the osteotomy.

When a Densah® Bur is rotated at 800-1500 RPM in a reversed, counterclockwise direction with steady external irrigation, called “Densifying Mode”, a dense compacted layer of bone tissue is formed along the walls and base of the osteotomy. Scientific literature has suggested that dense compacted bone tissue produces stronger purchase for dental implants, higher implant stability, and may facilitate faster healing.

Each Densah® Bur features patented multiple, precision-ground flutes within a tapered geometry designed to produce a fast feed rate in two modes of operation. The taper design allows the surgeon to constantly modulate pressure and regulate irrigation.

The flutes are tipped with a proprietary chisel edge that concentrates thrust force while reducing tool chatter to produce smooth haptic feedback that intuitively allows the surgeon to make “on the fly” adjustments.

In the “Densifying Mode”, downward surgical pressure coupled with steady external irrigation creates a gentle hydrodynamic pressure wave, which expands a pilot osteotomy without excavating bone tissue with minimal heat elevation. A densified zone of surrounding bone is generated while plastically expanding the bony ridge at the same time.

In the “Cutting Mode”, the Bur is rotated at 800-1500 RPM in a clockwise (CW) direction to precisely cut bone if needed.

A Densah® Bur kit contains Densah® Burs of progressively larger diameter, which are to be used sequentially to achieve the desired osteotomy size. Densah® Burs can be used with all standard engines and implants.

Clinical Versatility of Osseodensification

T

he Densah® Bur technology is based on a novel biomechanical bone preparation technique called “osseodensification.”

Unlike traditional dental drilling techniques, osseodensification does not excavate bone tissue. Rather, bone tissue is simultaneously compacted and autografted in an outwardly expanding direction from the osteotomy, somewhat akin to a traditional hammered osteotome but without the trauma and other limitations. When a Densah® Bur is rotated at high speed in a reversed, noncutting direction with steady external irrigation, a strong and dense layer of bone tissue is formed along the walls and base of the osteotomy. Dense compacted bone tissue produces stronger purchase for your favorite dental implant and may facilitate faster healing.

Densifying crust in osseodensification mode due to compaction autografting

Clinical advantages of osseodensification Some surgeons feel that osseodensification eliminates the guessing game of implant primary stability, which is helping them in their All-on-4 cases. Others have shared with us their positive results when using osseodensification to facilitate alveolar ridge expansion in both jaws.

They have told us that osseodensification is reducing the minimum amount of bone needed to predictably place an implant. Many surgeons have used the Densah® Bur successfully in sinus autografting procedures; we have included the steps for this procedure below.

Compaction autografting in the apex of the osteotomy facilitates sinus grafting

Maxillary sinus autografting 1. Flap the soft tissue using the instruments and technique normally used.

2. In cases where posterior residual alveolar ridge height is 7.0 mm, and additional vertical depth is desired, drill to the depth determined within an approximate safety zone of 1.0 mm from the sinus floor using a pilot drill (clockwise drill speed 800-1500 rpm with copious irrigation). Confirm pilot drill position with a radiograph.

3. Depending upon the implant type and diameter selected for the site, begin with the narrowest Densah® Bur. Change the drill motor to reverse-Densifying Mode (counterclockwise drill speed 800-1500 rpm with copious irrigation). Begin running the bur into the osteotomy. When feeling the haptic feedback of the bur reaching the dense sinus floor, modulate pressure with a gentle pumping motion to advance past the sinus floor. Maximum advancement past the sinus floor at this stage must not exceed 1.0 mm. Confirm the first Densah® Bur vertical position with a radiograph.

4. As the next Densah® Bur advances in the osteotomy, bone will be pushed toward the apical end and will begin to gently lift the membrane and autograft compacted bone. Use the sequential Densah® Burs in Densifying Mode (counterclockwise drill speed 800-1500 rpm with copious irrigation) with gentle pumping motion to achieve additional vertical depth and maximum membrane lift of 3.0 mm (in 1.0 mm increments) and reach final desired width for implant placement. In cases where residual alveolar ridge height is less than 7.0 mm, and additional lift of the membrane (more than 3.0 mm) is desired, a bone graft material can be placed into the final width osteotomy. Use the last Densah® Bur in Densifying Mode (counterclockwise drill speed 200-600 rpm with slow irrigation) with gentle pumping motion. The Densah® Bur must only facilitate the graft material compaction to lift the sinus membrane further, and not advance beyond the sinus floor.

Implant insertion will then drive the graft material into the final desired depth.

5. Place the implant into the osteotomy. If using the drill motor to tap the implant into place, the unit may stop when reaching the placement torque maximum. Finish placing the implant to depth with a torque indicating ratchet wrench.

A micro-thin forceps and simplified method for the placement of tunnel connective tissue grafts

T

his newly designed instrument by Laschal Surgical represents a significant advancement of the tunnel process for gingival grafting. Because of its patented use of “flexibly resilient” materials, basic engineering principals, and designs, it is atraumatic. The forceps can, therefore, grasp the graft, albeit connective tissue or AlloDerm® (LifeCell™), and pull the graft through the tunnel without the fear of ripping or tearing the tissue that would be associated with uncontrolled operator force.

This completely eliminates or greatly reduces iatrogenic damage and gives the operator total control as the graft is positioned prior to anastomosis.

PRODUCT PROFILE

Salvin® Renovix® Guided Healing Collagen Membrane

T

he Renovix® Guided Healing Collagen Membrane from Salvin Dental is getting excellent reviews from doctors using it for pre-implant grafting procedures, including socket preservation, ridge augmentation, and sinus lifts. It combines the ability to drape and conform to the specific anatomy of a grafted defect, while maintaining structural integrity and elasticity. This combination of ideal handling characteristics helps make grafting procedures easier and more predictable.

When it comes to selecting the perfect membrane for guided bone and tissue regeneration, there are many choices. Yet most clinicians are still looking for the ideal barrier that combines the best handling and performance characteristics. Some collagen membranes remain stiff even after being hydrated, making it difficult to place over a ridge and conform to the shape of the defect. Other membranes have no memory and resemble wet tissue paper, making it extremely difficult to manipulate during surgery.

Renovix® was originally created for use in repairing pediatric cardiac defects.

Cardiac surgeons needed a resorbable membrane to protect the surgical site without migration, and to have it crosslinked in a way that significantly reduced the chance of an inflammatory response.

Based on these specific requests, the material used for Renovix® was developed.

Renovix® is fabricated from Type 1 porcine collagen, known to be one of the purest forms of collagen available. It is cross-linked with polysaccharide, a naturally occurring sugar, with excellent biocompatibility. The combined performance and handling characteristics of this membrane, along with specific requests from many implant surgeons, encouraged Salvin Dental to introduce Renovix® for guided bone-regeneration procedures.

Case reports and clinical documentation are an important part of the decisionmaking process when determining how regenerative products will perform. Steve Wallace, DDS, MHS, from Wilmington, North Carolina, has used Renovix® in over 25 cases as a guided regeneration barrier after extraction and grafting of maxillary first and second molars in preparation for implant placement. Dr. Wallace made the following statement detailing his clinical experience with Renovix®: “Primary flap closure over maxillary molar extraction sites is always difficult to achieve. I have been using Renovix® as my barrier over these 60 Implant practice

grafted sites to exclude soft tissue ingrowth.

I have seen that Renovix® remains intact up to 13 weeks and consistently promotes soft tissue closure over it with minimal inflammation.”

When it is first removed from its sterile packaging, Renovix® is transparent and fairly rigid. Once hydrated, Renovix® becomes opaque, making it easy to identify when brought into the surgical field, and very easy to manipulate. Doctors have said that they get their best results when trimming it after it has been hydrated.

Renovix® is very thin, yet has remarkable tensile strength. This characteristic provides several clinical advantages. First and foremost, it can easily be tacked or sutured to the surgical site if needed. Next, it can be tucked into small tunnel incisions using a micro periosteal elevator without concern that the instrument will easily puncture through the membrane. Finally, the fact that Renovix® is thin and resilient enables the clinician to elevate smaller flaps, leaving more of the periosteum and blood supply undisturbed for faster healing and less patient discomfort.

James Woodyard, DMD, MS, from Newburgh, Indiana, made the following statement regarding his experience with Renovix®: “The thinness and excellent tensile strength of Renovix® allows me to create small tunnel incisions and tuck it under the tissue without tearing the membrane. With thicker membranes that I used in the past, I had to create large full-thickness flaps, and many of the other thin membranes had a tendency to tear when I tried to tuck them. When I decrease the size of the flap elevated and exposure of bone, I decrease postoperative swelling, pain, bone loss, and discomfort for the patient. The less invasive I can be, the less complications I have. I

am extremely pleased with the results that I have seen when using Renovix®.”

Renovix® is available in three different sizes and is individually packaged sterile for immediate use. Many doctors like 15 mm x 25 mm size because it will typically fully cover a grafted extraction socket from the buccal to the opposing lingual plate, maintaining full coverage over the ridge, without having to select a larger size. This unique size reduces waste and saves money by often eliminating the need to select the next larger size.

ON THE HORIZON

Mentorship, more important than ever!

Dr. Justin Moody reflects on the importance of inspiring others

Y

esterday one of my patients asked me how I became interested in dentistry, and I told her that my childhood dentist encouraged me to look into the profession.

She then asked me, what about implants?

How did I become interested in dental implants, and did I ever think that I would one day be teaching others? I answered that a dentist named Dr. Roger Plooster inspired my passion for dental implants, and no, I never really had thought about teaching others.

As I sat in my office that night finishing up my notes, I kept thinking about my conversation earlier that day. How I got to this desk was truly through a lot of hard work and help from some key people along the way, my MENTORS. We have many mentors in life — parents, teachers, and friends who guide us, mold us, and push us to be the very best.

Over the years, I have had many associates come through my practices; early on it was about getting some help in a time when I was too busy. Sadly, these doctors moved on to work elsewhere and to establish their

Today, I realize that I failed them for it wasn’t really about the nice office, fancy technology, or even the money … It was about mentorship. Dental school has always been hard, but now it’s even harder with the kinds of debt today’s young dentists have.

Mentorship is so much more than showing someone how to do a procedure.

It’s about showing them that it’s truly an honor and a privilege to call someone a patient, that you should always treat patients how you yourself would want to be treated,

and that compassion and humility are good for the profession.

Years ago, I thought that success was measured in money and material things; today those items don’t register on my list.

Opening an email to see an X-ray of the first dental implant one of my students placed or a phone call from someone who tells me that I made a difference in his/her life — that’s success! It is true that I love my job, and I love helping my patients improve their lives with dental implants, but I am the most humbled by those that call me their mentor. IP

AAID Annual Conference blends classic with cutting edge

T

he science of implant dentistry sees improvements and innovation every day.

The American Academy of Implant Dentistry’s 64th Annual Educational Conference at Caesars Palace™ in Las Vegas, Nevada, on October 21-24, 2015, blends the classic with tomorrow’s innovations.

Attendees have the opportunity to earn as many as 20 hours of continuing education credit focused on implant dentistry. The theme of the conference, “Where Classic Principles Support Cutting-Edge Implant Dentistry,” serves as a reminder of the groundwork laid over 60 years ago by the dental implant pioneers. Caesars Palace serves as a classic Las Vegas backdrop to fit the classic educational theme of the conference.

Over 1,000 implant dentistry professionals will hear from Dr. Carl Misch, one of the pioneers in implant dentistry, as he delivers one of our keynote addresses on Thursday afternoon, October 22. Back by popular demand is Dr. Daniel Alam, who was the leading microsurgeon on the first face transplant performed in the United States.

Dr. Alam brought the audience to its feet at the 2010 AAID Annual Conference. This year, he will inspire attendees with his presentation on Face Transplantation: Past, Present, Future, as the closing keynote speaker of the Conference.

Over 3½ days, world-renowned clinicians will review time-honored dental implant techniques and explore cutting-edge dental implants. They will evaluate the latest concepts in dental implant treatment planning and rethink the science and practice of implant dentistry.

Attendees have the chance to interact with leading clinicians 64 Implant practice
