L
ooking back on the Academy of Osseointegration’s recent Annual Meeting, I am impressed with the level of collegiality among our profession, and the importance of it to the vitality of dentistry in the 21st century; and perhaps nowhere is it more vital than in implant dentistry. Collegiality is defined as the relationship between colleagues — those united in a common purpose. Whether we are specialists or general dentists, students or seasoned practitioners, living in the United States or across the pond, our shared goal is to enhance oral health Alan Pollack, DDS and make our patients smile. While technology has advanced to improve success rates and shorten healing times, there has also been an explosion of information regarding choices for implant surfaces, attachment types, restorative design, and materials. It’s not easy to navigate and identify the most relevant and up-to-date information and avoid the trap of being creatures of habit, continuing to do what we’re most familiar with. While very few of us are able to quote every clinical article in the past 5 years, it is imperative that we keep current with trends and best practices. And the best way to do that is through sharing both successes and problems with colleagues. In addition, we’re facing increasing issues of long-term and medically related complications, e.g., peri-implantitis and medication-related post-surgical and late bone complications. The plethora of decisions we face makes it evermore imperative that we understand the risks, as well as the differences, advantages, and disadvantages of each option. That’s why it’s so important for us to come together and participate in vetted programming and educational events we can trust. As a unified group of committed clinicians, we can gain new perspectives and challenge our old ways of thinking. We all, dentists and scientists across the spectrum of disciplines and backgrounds, need to teach, challenge, and critique one another; and we need to do it in an environment independent of outside influences. Collegiality also fosters a cross-fertilization of ideas — spanning not only specialties, but also generations. While at this year’s meeting, I was reminded of — and inspired by — the enthusiasm, fresh thinking, and familiarity with the literature our young members brought with them. I also saw how our more tenured members offered insights into how to evaluate the “latest and greatest” advances that come along. With the global implant dentistry market expected to double by 2018, it is increasingly important for all dentists involved in implant dentistry to work together to represent our field in the best light possible and to keep success rates high, and our patients safe and happy with our professional skills. The Academy of Osseointegration (AO) is an organization that connects us all and has led the way in implant dentistry since 1985. Together, we evaluate emerging research, technology and techniques, share best practices, and coordinate optimal patient care using timely, evidence-based information. (And, I’ll let you in on a little secret: We have quite a bit of fun doing it!) If you’re considering joining AO, more information about member benefits can be found at www.osseo.org.

Working in my office
What can you tell us about your background?
When did you become a prosthodontist and why?
I received my DMD degree from the University of Montréal, Canada, in 1996. Following graduation, I moved to Boston to complete a Certificate in Advanced Graduate Studies in Prosthodontics and a master’s degree in Restorative Sciences in Prosthodontics from Boston University Goldman School of Dental Medicine. Years later, I became a Diplomate of the American Board of Prosthodontics and a Fellow of the American College of Prosthodontists (ACP). I currently serve as a Professor and Director of the Hugh Love Center for Research and Education in Technology at Loma Linda University School of Dentistry and maintain a part-time private practice limited to prosthodontics and implant dentistry in Glendale, California.
In dental school, I loved every discipline related to prosthodontics. I also had the chance to work with several instructors who were prosthodontists and came to realize that prosthodontics is what I would consider as a career path. Right after dental school in Montréal, I headed to Boston for my Prosthodontic training.
6 Implant practice
Is your practice limited solely to implants, or do you practice other types of dentistry? As a prosthodontist, I am a recognized expert when anything needs to be replaced in the patient’s mouth. I am a specialized dentist with advanced training in the treatment of crowns, bridges, implants, veneers, full dentures (conventional or CAD/CAM),
Dr. Nadim Z. Baba
partial dentures, snoring and sleep disorders, TMD or other jaw joint problems, and some other congenital conditions that affect the mouth. I am committed to improving patients’ results. Volume 9 Number 2
PRACTICE PROFILE
Do your patients come through referrals? Yes. Oral surgeons, periodontists, orthodontists, and general practitioners refer the majority of my patients. I also get patients referred by other satisfied patients who received their treatment in my office. As a prosthodontist, I am dedicated to the highest standards of care in the restoration and replacement of teeth, and for this reason, I maintain a close collaboration with all my referring colleagues during all the phases of treatment for the benefit of the patients.
How long have you been practicing implant dentistry, and what systems do you use? As a prosthodontist, I have been practicing implant dentistry for 20 years. I have worked with all the major implant systems between teaching at Loma Linda and working in my private practice. It basically depends on what my referrals use in their private practice. My office is located in a multi-specialty building and has three operatories, one designated for hygiene. I have an in-house laboratory operated by highly skilled dental technicians with tremendous amount of experience. A Dental Wings 7Series lab scanner (MontrĂŠal, Canada) was recently added to the state-of-of-the-art equipment already available in the lab. The office is paperless, and we use digital radiography and an in-house CBCT machine (Planmeca).
Putting a final touch to a denture and checking the quality of the finished laboratory work
What training you have undertaken? After completing my 4 years of dental school, I have trained for 3 additional years in prosthodontics followed by a master’s degree in Restorative Sciences in Prosthodontics at Boston University Goldman School of Dental Medicine. I then challenged and successfully passed a rigorous four-part examination conducted by the American Board of Prosthodontics (ABP) to become a Diplomate of the ABP. Being affiliated with a teaching institution and attending specialty meetings such as the ACP, AAFP, AP, and others, I am at the cutting edge of technology and information.
Designing a framework for a fixed partial denture using CAD/CAM technology
Who has inspired you? Several of my instructors and colleagues inspired me through the years. In dental school, three of my faculty (Dr. P. Boudrias, Dr. C. Lamarche, and Dr. P. Milot), who were prosthodontists, had a great impact on my decision to choose prosthodontics as a specialty. At Boston University, I had the honor of being trained with Dr. Steve Volume 9 Number 2

I feel blessed, lucky, and proud to have had the chance to know and work with each one of them in various stages of my professional career.
What is the most satisfying aspect of your practice? The most satisfying aspect of my practice is to visualize the transformation that patients go through during their smile makeovers and to see on their faces the degree of satisfaction and gratitude toward the work I accomplished.
Professionally, what are you most proud of?
innovative materials are used to provide patients with the finest dentistry can offer. The noncommercial, in-house laboratory, and highly skilled technicians utilize the latest technologies to design restorations of superior quality.
What would you have been if you had not become a dentist? If I did not become a prosthodontist, I would probably be a commercial pilot. I come from a family of six pilots from both sides of my parents. You could imagine what a family gathering would be when all these pilots meet together. They talk about airplanes all the time.

015 was a landmark year in the history of the dental industry. Zimmer Dental and Biomet 3i joined forces to become a leader in oral healthcare as the Zimmer Biomet dental division. Clinicians around the globe have since had access to a new level of customer service and extensive product portfolios that include a broad spectrum of surgical, restorative, regenerative, and digital dentistry solutions designed to improve the quality of life for patients. The Zimmer Biomet dental division is now uniquely positioned to provide continuing education programs that combine cadaveric and simulated patient training with didactic clinical presentations — all in one training center. Recognizing that education is critical to the advancement of dentistry, the dental division focuses on strengthening and enhancing the profession by offering industry-leading, scientific educational courses to dental clinicians from around the world through the Zimmer Biomet Institutes. The Zimmer Biomet Institutes in North America train more than 1,000 dental clinicians through more than 65 courses offered annually. General Manager of the Zimmer Biomet dental division, David Josza, remarked,
“The quality of the curriculum offered as well as the sophistication of the equipment and overall facility is outstanding. The simulation lab is the finest one I have ever experienced. It is impressive to see such a commitment made in the advancement of education in our field. I applaud the team at Zimmer Biomet.” — Howard Drew, DMD, professor, Rutgers School of Dental Medicine
“At an educational level, we strive to offer programs that complement skill sets and help clinicians achieve unprecedented levels of professional satisfaction and success, regardless of whether they are new to dental implantology or a seasoned practitioner.” In February, the dental division celebrated the grand reopening of the Zimmer Biomet Institute training center in Parsippany, New Jersey. The newly enhanced
20,000-square-foot dental training center provides professional educational courses for dental clinicians who are interested in restorative, surgical, and regenerative procedures. Training programs at this facility provide optimal hands-on experience and support to clinicians as they strive to refine their clinical skills. “We are thrilled to reopen our doors as the Zimmer Biomet Institute and excited

to build on the foundation of our ability to provide dynamic professional training,” said Ken Varner, the Director of Institutes for the Zimmer Biomet dental division. “During our reopening in Parsippany on February 10, clinicians were able to see firsthand the bestin-class dental training offerings available in our new facility.” Courses offered at the new center include simulation workshops in a proprietary, stateof-the-art patient simulation laboratory. Reallife, simulated patient scenarios are reviewed and practiced during hands-on sessions with lifelike mannequins and anatomical models. This gives clinicians the unique opportunity to learn complicated implant procedures, including regenerative techniques, provisional and definitive restorations, and immediate implant loading. The simulation lab is equipped with all the tools and supplies that a clinician requires when treating a patient. Each learning station has a computer for accessing reference materials and simulated Volume 9 Number 2
patient materials, including radiographs, CT scans, and models that are specific for the exercises. The mannequins feature soft tissue and bone that have cortical and cancellous layers, soft-tissue lined sinuses, and wired inferior alveolar nerves. Ideal for clinicians skilled in basic implant surgery who want to refine their surgical knowledge and techniques, on-site cadaveric workshops enable clinicians to immediately implement what they’ve just practiced in the simulation lab on human tissue. Howard Drew, DMD, a professor at Rutgers School of Dental Medicine, attended a course at the new Parsippany Institute and commented, “The quality of the curriculum
offered as well as the sophistication of the equipment and overall facility is outstanding. The simulation lab is the finest one I have ever experienced. It is impressive to see such a commitment made in the advancement of education in our field. I applaud the team at Zimmer Biomet.” In addition to simulation and cadaveric training, didactic lectures and case reviews are given by guest speakers who travel from across the world to present on current and emerging procedures, technologies, and products. The Institute is equipped with advanced audio and visual technology, such as wireless projection and the ability to stream live presentations and demonstrations from Implant practice 11
CORPORATE PROFILE one training room to another and to various locations around the globe for an optimal educational experience. “Having lectured in many centers around the world, the Zimmer Biomet Institute offers a one-of-a-kind learning experience in a center designed specifically with clinicians’ needs in mind,” confirmed Harold S. Baumgarten, DMD. Courses range from a basic restorative program for clinicians who restore fewer than five implant cases each year to advanced surgical cadaveric workshops designed for clinicians who are actively placing and restoring implants. Depending on the course level, clinicians learn everything from basic dental implant restoration and associated techniques to advanced surgical procedures and the use of regenerative materials. Restorative topics include impression making, anterior esthetics, provisional restorations, fixed versus removable dentures, and full-arch restorations. Surgical topics range from soft-tissue grafting procedures, suturing techniques, sinus lifts, and socket
procedures to ridge augmentation. Courses typically last 2 to 3 days and are approved for continuing education credits. Building on the momentum from the New Jersey facility, plans are in order to meet the growing demand from clinicians and the expanding global business of dental implantology. Construction is in progress for two new facilities — one in Carlsbad, California, on target to open in the third quarter of 2016, and another in Shanghai, China, scheduled to open its doors by the end of this year. Plans are also being discussed to open a new Institute in Palm Beach Gardens, Florida, in 2017. In addition to keeping global education a priority, the Zimmer Biomet dental division, says Josza, will continue to focus its efforts on challenges faced by clinicians to meet patient expectations. “Implantology is about the solutions that you are ultimately offering clinicians so they can provide exceptional outcomes to patients. It’s not just what we make; it’s what we make possible.” As an affiliate of one of the largest musculoskeletal companies in the world,
the Zimmer Biomet dental division has access to the latest technology, talent, and resources to drive growth and accelerate the development of innovative solutions. Groundbreaking technologies such as the Zimmer® Trabecular Metal™ Implant, the 3i T3® Implant, the BellaTek® Encode® Impression System, and the Zimmer Dental 3.1 mmD Eztetic™ Implant System are a sampling of the comprehensive range of products that address clinicians’ daily clinical challenges. Collectively, the Zimmer Biomet dental division has conducted more than 175 preclinical and clinical research studies in the past 10 years, and there are more than 650 published articles on the surgical, restorative, and regenerative products. They have operations in 25 countries around the world and sell products in more than 100 countries.

FINANCIAL FOCUS
Living with the choices we make Tony Robbins and Tom Zgainer discuss why you should understand how fees in your retirement plan investments will affect your future and that of your employees
A
s this article was written, the presidential campaign had officially started with the Iowa caucus now completed. In each of our states, we’ll soon enjoy the great individual privilege of choosing who we think will be the most suitable candidate in each party. When November 9 rolls around, and the results of the previous day’s election are confirmed, we’ll then have to live with the choices we made, or did not make, for the next 4 years. When it comes to our retirement planning, the choices we make today related to our investment options and their associated fees need to be made with a much longer time horizon in mind. Twenty to thirty years of life after active work has completed is now the norm. And if we intend to work another 10-25 years, the opportunity for the positive effects of compounding growth in your retirement savings will make all the difference in the quality of life we might enjoy in retirement. Different from what you might choose for yourself, be it a presidential candidate or a particular investment, if you are the sponsor of a retirement plan, your employees are counting on your decisions, and the ramifications of those choices good or bad. You are choosing for them, as they generally have no say so in the matter. And yet it’s their money, their future. It is a very significant responsibility often overlooked. We review hundreds of 401k plans per month, and while the employers are certainly well intentioned, so little is often understood regarding the effect of investment-related fees over time. A recent study found that the average total cost for a small business retirement plan declined to 1.46% over the past year, and that within this amount, the investment-related expenses typically borne by participants average 1.37%. This particular study defined small plans as those with 50 participants or $2.5 million in assets. However, if you own or work for a business that has fewer than 50 participants or Peak performance strategist Tony Robbins and Tom Zgainer, founder and CEO of America’s Best 401k, offer advice on growing retirement savings.
14 Implant practice
less than $2.5 million in plan assets, odds are you’re paying a substantial amount more in 401k fees. Plans in this demographic are defined as “micro” plans. It is not uncommon for the underlying investments in these plans to have expense ratios averaging between 1.50% and 2.50%. This has a major impact on retirement savings over time that can be difficult to decipher. Why is this important to you? While 1.00% may sound insignificant, the costs of your investments can have a staggering effect on your retirement savings over time. According to the Department of Labor (DOL), paying just 1 percentage point more in expenses over the course of 35 years could reduce a worker’s retirement savings by nearly 28%. For example, Bob is a participant in a plan offered by his employer with a 401k balance of $25,000 that earns 7% over the next 35 years. If Bob paid 0.50% in fees, even if he stopped making new contributions, his account would grow to $227,000 at retirement. But if he paid fees totaling 1.5%, the savings would rise to only $163,000, or 28% less. A startling statistic is that in a recent survey by the AARP, nearly 70% of participants in 401k plans believe they are paying no investment-related expenses or that their employer absorbs these fees. Nearly 40% of plan sponsors, the business owners bearing the fiduciary liability of the plan, who have chosen the providers and investments in the plan, do not know the average expense
ratios of the funds in the plan. Both figures are truly astonishing. A review of your own 401k fees and investment options should be a near-term action item. Plan sponsors are required by the Department of Labor to compare their current plans against alternatives on a regular basis to be sure all fees are reasonable and prudent. With the proliferation of lawsuits that exist — many very high-profile — recently in the news brought on by plan participants and almost always related to excessive fees or the use of proprietary funds in the 401k plan, it makes all sense to have a documented process and report of your findings in case a DOL examiner knocks on your door.

CASE REPORT
Management of severe horizontal and vertical maxillary deficiency via tenting and sub-nasal augmentation with PRGF Dr. Pierre J. Tedders discusses a technique for grafting ridges requiring large areas of reconstruction
M
anagement of the comprehensive dental implant patient routinely requires guided-bone regenerative techniques. The benefits that the edentulous patient receives from an implant reconstruction can be life altering. Although depending on the specific patient, the duration of edentulism, the prosthetic, and utilization of the prosthetic, the alveolar and basal bone available for the reconstruction may range from sufficient to severe atrophy. Beyond the intraoral effects, these patients also suffer consequences of esthetics, decreased function, and psychological effects. Numerous predictable surgical protocols have been developed to manage the atrophic ridge. In those patients who have sufficient vertical height, with moderate to severe horizontal deficiency, an onlay graft via “tenting” procedure may be
most appropriate. This technique is useful in grafting ridges requiring large areas and may not result in the excessive facial remodeling of the implant as traditional block grafting. The following case will demonstrate the surgical procedure to overcome these types of deficiencies. The surgical plan includes a full periosteal flap reflection, nasal mucosal reflection, augmentation of the alveolar ridge, via onlay grafting with tenting to gain necessary width, and augmentation of the nasal cavity to gain height for the anterior implants utilizing Plasma Rich in Growth Factors (PRGF). The healing phase for this patient was 3 months prior to placing six root-form endosseous implants. This healing phase timing is appropriate when combining growth factors and the welldocumented initial stability of the OCO
Biomedical Engage™ implant with its Bull Nose Auger™ tip design.
Clinical case The patient presented with a chief complaint of ill-fitting maxillary complete denture. She reported that the fit and function of her maxillary prosthesis has negatively affected the quality of her life. The patient is ASA I with no contraindications to dentoalveolar surgery. Thorough clinical and radiographic examination reveals moderate to severe maxillary arch deficiency (Figures 1-3). Consideration was made for a traditional block-grafting procedure and combined block grafting with ridge splitting. Due to the size of the proposed graft and current known limitations to block grafting, the option was made for onlay grafting via a tenting procedure with sub-nasal elevation and augmentation with PRGF. A full thickness incision was made maintaining 3 mm of keratinized tissue to the facial of the incision line. Posterior superior vertical releasing incisions were made, and a full

CASE REPORT thickness reflection was completed exposing the facial alveolar and basal bone exposing the extent of the deficiency (Figure 4). Minimal alveoloplasty was completed followed by decortication, for regional acceleratory phenomenon aiding in angiogenesis (Figure 5), and bilateral reflection of the subnasal mucosa. Care is taken not to reflect the nasal mucosa as far posteriorly as the nasal cavity extends (reflection approximately 8-10 mm posteriorly) (Figure 6). Bone fixation screws (Salvin® Dental) were strategically fixed to the maxilla. The fixation screws serve to tent the collagen type I membrane and minimize the negative effects of compression from the muco-periosteum, peri-oral soft tissues, and musculature
(Figures 7 and 8). The fixation screws are approximated to slightly larger than the new proposed alveolar ridge — the final result ending with a minimum of 2 mm of bone to the facial and palatal of the dental implant. Approximately 64 cc of blood was drawn from the right antecubital fossa and prepped with 8 cc allograft (250 um-1000 um) for PRGF separated into “membrane” (Figure 10) and “graft” fractions. The allograft is osteoconductive, or serves as a scaffold for the predictable inflammatory response and remodeling. The PRGF increases the volume of localized growth factors, TGF-beta, and PDGF “inflammatory cytokines.” The growth factors accelerate the inflammatory cascade, the rate of angiogenesis, and further serves
as a filler. With the addition of growth factors, there is a significant decrease in reported postoperative complications. A type I collagen membrane was modified with tissue scissors and secured to the palatal tissue with 4-0 polyglycolic acid (PGA) sutures (Figure 11). The collagen membrane serves several functions: 1) the collagen membrane prevents epithelial migration into and displacing the graft and 2) contains the graft material. The PRGF and allograft “graft” were moderately condensed between the nasal floor and the nasal mucosa to a total height of approximately 15 mm from the alveolar crest. The graft was then moderately condensed to follow the new proposed facial-palatal ridge to

PGA (Figure 16). The patient was prescribed a postoperative chemotherapeutic regimen, chlorhexidine rinse, an anti-inflammatory, and a narcotic pain reliever as needed. The patient was seen at 1 week, 2 weeks for suture removal (Figure 17), and 4 weeks to monitor the healing process. The patient then entered a total 12-week healing phase. At the 12-week time frame, the new maxillary arch was exposed using a full-thickness incision from right to left tuberosity with disto-vertical releasing incisions to gain access to the tenting screws for removal and implant placement. The remaining ridge demonstrated sufficient bone regeneration, to the head of the fixation screw, for the planned six 4.0 x 12 OCO Engage™ implants (OCO Biomedical) (Figure 18). All tenting screws were removed, and minor alveoloplasty (Figure 19) was completed. Paralleling pins (Figure 20) were used to maintain parallelism for the placement of six 4.0 x 12 OCO Engage implants utilizing the simplified OCO Biomedical twodrill surgical sequence. The surgery was performed in a singlestage approach, and 5-mm tall trans-mucosal healing abutments were placed. For this specific surgery, the OCO Engage implant
Figure 14
was selected for its outstanding primary stability. The Engage is a bone-level implant with a variable self-taping thread pattern. The coronal micro threads increase the bone-toimplant surface contact, and combined with the Bull Nose Auger tip, provide the initial stability required for predictable success with a limited healing phase. The initial stability of the implants ranged from 40N/cm to 60N/cm of torque (sufficient for immediate load). The tissues were approximated with interrupted horizontal mattress sutures (Figures 21 and 22), and the patient was seen at the 2-week and 4-week postoperative visits. At the 3-month follow-up visit, the implants were torque tested to 35N/cm, and the patient was referred to her general dentist to complete the prosthetic phase of her treatment. The final prosthesis was a maxillary implant-retained overdenture. Note: In treatment planning of the implant overdenture, if the palate is to be removed out of the final denture, the implants must be splinted. The palate and the alveolar ridge provide the support and stability of the prosthesis. If individual locators are utilized, and the palate is removed, the prosthetic becomes an implantretained and implant-supported prosthesis, leading to potential progressive bone loss

slightly overfill beyond the tenting screws to form the proposed new facial surface of the maxillary alveolus (Figure 11). The collagen membrane was then folded over and secured to contain the graft (Figure 12). With the entirety of the graft condensed and secured with the collagen type I membrane, the tissues do not approximate passively. The number one complication of a ridge reconstruction of width is suture line opening. Suture line opening exposes the underlying graft, and a negative inflammatory response follows, leading to excessive remodeling and potential infection (Figure 13). Horizontal periosteal releasing incisions and blunt dissection of the tissues was completed to allow for the tissues to approximate passively (Figure 14). Initially, 12 horizontal mattress sutures were utilized to approximate the tissues. The closure must be primary and tension free. Placing the horizontal mattress sutures at the mucogingival junction everts the tissues and releases the tension off the incision line. Further, multiple sutures must be used to prevent suture line opening due to suture failure during the phase of edema (Figure 15). Final incision line closure was completed with continuous interlocking suture with 4-0

A clinical examination (Figure 24A) and CBCT were performed. All tissues remain firm, pink, and asymptomatic. The remaining maxillary ridge has maintained width and bone to the facial of the implants. (Note comparison photos preoperative Figure 24B and postoperative.) Figures 25C-25D demonstrate the augmented bone of the nasal cavity. Figure 25 shows the 2-year postoperative CBCT. Thorough knowledge and experience with the different ridge augmentation and bone manipulation techniques offer reconstructive options that directly improve the quality of life for our patient base. This case presented an onlay graft via a tenting procedure, which offers another option to obtain necessary bone quantity for implant placement. The procedure is relatively simple and may offer more predictable results to traditional block grafting. The patient is continuing her treatment with an immediate placement and immediate load transitional mandibular hybrid denture with five mandibular OCO implants in the A, B, C, D, and E positions in March 2016. Additionally, it has been highly recommended that an implant-retained and tissuesupported maxillary implant overdenture with a locator bar be fabricated. The patient stated that there has been a significant improvement in the quality of her life following her implant reconstruction. This was, and should be, the ultimate goal of our implant treatments.

Using the All-on-4® treatment concept to treat atrophied and over-treated jaws Dr. Reza Faridrad presents a case using the All-on-4 concept for insufficient bone in the posterior maxilla and mandible
I
t has been more than 20 years since the concept of All-on-4® (Nobel Biocare®) (Malo, Lopes, and De Araujo Nobre, 2011) has been introduced into the profession. The treatment of the resorbed edentulous jaws using a fixed implant-supported prosthesis (Malo, Lopes, and Costa, 2008) has always been a challenge for dentists. There are still debates among the profession about the credibility of this treatment modality. Needless to say, that there are other implant companies, such as Zimmer and Bredent (fast and fixed), following the similar philosophy. There is no doubt in my mind that the All-on-4 concept is the treatment of choice (both for me and my patients) when there is insufficient bone in the posterior maxilla and mandible (Rangert, et al., 2005; Malo, Rangert, and Nobre, 2005; Malo, Rangert, and Nobre, 2003; Malo, et al., 2011). Needless to say that the zygomatic implants and quad-zygoma options are available for more severely resorbed maxilla (when there is insufficient bone in the premolar and molar regions). These options will save time for both the patient and the operator without the need for bone-grafting procedures.
Poor planning and rushing into treatment is not uncommon among the profession when it comes to edentulous jaws. There are three types of failures: 1. Short-term — during and shortly after the procedure (e.g., bleeding, lack of primary stability, etc.) 2. Midterm — problems arising in the first few weeks (e.g., infection and mobility in the fixture, loosening of the internal hex screw, problems with the occlusion, poor esthetic results, etc.) 3. Long term — problems arising after a few months and years (e.g., periimplantitis and loss of hard and soft tissues, etc.).
Case study In this case, I have tried to illustrate how the All-on-4 concept helped me to treat a patient and give her teeth, smile, and, more importantly, chewing ability back. Her previous dentist (implantologist) had decided to treat the case in a staged manner using the immediate placement protocol.
Seventy-year-old Mrs. TB was referred to me for a second opinion in 2012. Mrs. TB was treated by a visiting implantologist from California, in Belgium in 2008. The patient presented to me with fixedbridge restorations fitting over the 14 fixtures (unknown manufacturer), seven in the maxilla and seven in the mandible. The halitosis and poor plaque control around the fixtures with readily bleeding soft tissue around those fixtures was a horrible experience. The patient was distressed, and she was in a lot of pain and discomfort. Her chief complaint, not surprisingly, was pain, bleeding, and not being able to chew and eat properly. Nearly all the fixtures were exposed, and the bone loss was well past the first thread (Figures 1-5). There was no mobility in the bridges, but I noticed that the UL1 was looking out of place, and its shade was not matching the rest of the porcelain work. It became clear that this part was soldered onto the bridge separately. The bruxism took its toll, and the sign of it was evident on the worn down ceramic of the lower bridge occlusally (Figure 6).
The success of All-on-4 The success and survival rate of the All-on-4 treatment has been assessed by many clinicians (Malo, et al., 2011; Malo, et al., 2011) and research groups.

An Orthopantomogram (OPG) X-ray and CBCT examinations revealed severe bone loss on the upper fixtures with poor planning for placement. It has been confirmed with the patient that these fixtures were positioned immediately in the extraction sockets for the upper left canine and premolars. In the mandible, the LR5 fixture was perforated and inserted in the right inferior dental nerve canal, and the patient already had anesthesia of the right lower lip. During all the visits the patient had with her dentist (implantologist), she was always reassured that the numbness would be temporary, that the implants and restorations were in a very good shape with minimal bone loss around them, and the dentist was actually very happy with the result.

The high-speed handpiece, trephine, forceps, and implant removal kit were used in order to remove all the previous restorations (Figures 7-10). The alveolar ridge was reduced and trimmed according to the All-on-4 protocol. The fixtures (four upper and four lower) were inserted in the position LR4-5 area and angled away from the mental foramen and previously perforated ID canal. Needless to say, that the patient had some improvement in her numb lip, and she described it as “less heavy” (Figure 19).

All the created sockets and damaged ridges were augmented with Bio-Oss速 (Geistlich), covered using Geistlich bilayer GBR membrane, and primary closure was achieved using Vicryl速 (Ethicon) undyed suture material. After taking impressions, the temporary bridges were made by the technician on site and fitted. The vertical height and occlusion were checked and adjusted. This part of the job took approximately 6 hours. The patient was experiencing less soreness and bleeding from the soft tissue over the ridge as her erosive lichen planus appeared to be less symptomatic; although the condition affected all her mouth, it stayed unchanged on her buccal mucosa and pharyngeal areas. There was obvious improvement over the ridges and floor of the mouth (Figures 12-18 and Figure 20). The final bridges were made and fitted 6 months later, and the patient has fully recovered from her previous experience and managed to eat and chew effectively (after 8 years) with minimal flare-ups from her inflamed oral soft tissues. The bleeding index from the soft tissues around the fixtures was minimal, and the halitosis issue was also resolved (Figures 21-27). Volume 9 Number 2

Conclusion The All-on-4 concept for total rehabilitation is clinically effective but challenging. The survival rates of the implants and restorations is high according to the short-, medium-, and long-term studies. The All-on-4 can be offered routinely to most patients in need of a complete edentulous rehabilitation. The use of NobelGuide (Nobel Biocare®) for computer planning can simplify the treatment if the patient is totally edentulous. IP

Drs. Lyndon F. Cooper and Ghadeer N. Thalji present a simplified approach to divergent implant placement
D
ental implant therapy for the edentulous mandible is highly successful when measured at the level of the dental implant. When component and prosthetic complications are considered, recent systematic reviews suggest that component and prosthesis complications occur frequently. Many of these complications are related to prosthesis design and have been attributed to the cantilever designs that impose significant bending moments and stress on the prostheses and components. The intentional divergence of implants from mutually parallel placement restricted to the parasymphyseal mandible has been proposed (Malo, et al., 2003) and has been recently substantiated by a retrospective evaluation revealing greater than 98% implant success (Malo, et al., 2011). The distal displacement of the terminal implants supporting mandibular implantsupported fixed dentures (ISFD) requires the use of abutments that geometrically reconcile the nonparallel arrangement of the implants and permit relative parallelism of the abutments. The aim of this case report is to illustrate the alternative use of conical interface abutments to simplify the construction of mandibular ISFD supported by four implants with intended divergence.

premolar using a fixed dental prosthesis. A mandibular denture setup was waxed to characterize the position of teeth for the proposed interim denture and final prosthesis (Figure 3). The Class III skeletal relationship was adapted to a Class I tooth arrangement. After reviewing treatment and obtaining informed consent, additional diagnostic measures for the surgical treatment were performed. The mandibular denture was flasked and processed in heat polymerizing resin (LucitoneÂŽ 199, Dentsply) using a conventional compression technique.
Thereafter, the mandibular denture was duplicated using a radiopaque resin (Biocryl-X radiopaque acrylic resin, Great Lakes Orthodontics) polymerized in a custom laboratory putty mold (Figures 4A-4B). A cone beam CT image was made of the patient wearing this radiographic template, and the DICOM files were imported into planning software (Dentsply Implants). Four implants were located within the parasymphyseal mandible and in relationship to the visualized denture teeth (Figure 5A). The implant selection and placement was performed to account for primary stability and osseointegration, restorative dimension, and minimal cantilever length for the available distribution of the implants. The targeted planning goal was to assure that there were at least four implants of >10 mm length, >10 mm of restorative dimension, and >10 mm of anterioposterior implant distribution (English 1990; Rangert, et al., 1989) to permit a cantilever of one premolar and one molar tooth (approximately 15 mm). Achieving these Volume 9 Number 2

Surgical treatment Four implants (OsseoSpeed™ TX, 4.0S x 11mm at the LL4, LR2, and LR4 sites, and a 3.5S x 11mm Dentsply Implants at the LL2) were placed in the parasymphyseal mandible. Under local anesthesia, a mucoperiosteal flap was elevated from the left molar region to the right molar region of the mandible. An alveoloplasty was performed from the left premolar region to the right premolar region with removal of approximately 4 mm of crestal bone (Figure 6A). This resulted in the exposure of a mandibular alveolar crestal shelf of approximately 5 mm-6 mm in buccolingual width and afforded an additional 3 mm of restorative dimension. Using the radiographic template with appropriately oriented 2.5 mm diameter guides drilled for surgical orientation, 2.0 mm osteotomies were placed to 4 mm-5 mm depth through the template. After affirming the proper orientation of the four osteotomies, each osteotomy was sequentially enlarged to 11.0 mm x 3.7 mm for sites Volume 9 Number 2
LL4, LR2, and LR4 and 11.0 mm x 3.2 mm for the LL2 according to the implant manufacturer’s recommended protocol (Figure 6B). Subsequently, 11.0 mm x 4.0 mm or 11.0 mm x 3.5S implants were placed into each osteotomy with primary stability (Figure 6C). Next, a conical interface abutment (Uni-Abutment, Dentsply Implants) was placed with hand torque into each of the four implants, and the mucosa was sutured circumferentially to each of the abutments (Figures 7A-7B). On each of the 20º conical interface abutments, machined-titanium temporary cylinders (Dentsply Implants) were placed with hexed bridge screws using finger pressure only. The access chambers of the cylinders were filled with VPS impression material to exclude acrylic resin. The complete denture was relieved to accommodate the temporary cylinders but with the full extension of the flanges intact. Upon closure, the coincidence of the denture maximum intercuspation at centric relation confirmed that the temporary cylinders did not displace the denture orientation. At that position, each of the four temporary cylinders was incorporated into the denture

using autopolymerizing acrylic resin with a rubber dam placed beneath the cylinders to protect the surgical site. The conversion prosthesis was then refined by removal of the flanges and eliminating the cantilever extension beyond the mesial cusps of the first molar. The prosthesis was delivered using four hex bridge screws, and the access holes were filled with VPS material.
Restorative treatment After 8 weeks of healing, the patient returned for an impression of the abutments to construct the final prosthesis. First, an inter-occlusal record using the existing interim prosthesis at centric relation was taken. Then, the interim conversion prosthesis was removed, the stability of the implants and abutments was verified, and an impression of the implant abutments made at the level of the 20º conical interfaces using a stock tray and VPS impression material.

Figure 11: Diagramatic representation of the extent of divergence that is accommodated by 20º conus abutments. Note that at 40º of divergence, the bridge screw access would be lingual to the incisors (anterior) and within the first molar (posterior). Less divergence (20º-25º) is easily accommodated and readily restored with a short ( ~10 mm ) cantilever.
The master cast was poured to incorporate 20º conical interface analogues without a soft tissue moulage (Figures 8A-8B). A verification index was fabricated using four impression copings and acrylic resin (GC Pattern Resin™) (Figure 9). The verification index was tested clinically to confirm the accuracy of the master cast. The interim conversion prosthesis and the interocclusal record were used to mount the mandibular master cast in correct relationship to the maxillary cast. A shade was taken for fabrication of the final prosthesis using nanohybrid composite/resin teeth (SR Phonares® II, Ivoclar Vivadent®).
Laboratory procedures The fabrication of the mandibular prosthesis required CAD/CAM design and milling of a titanium alloy bar. For this process, the dentist must provide the laboratory or milling center with a) a master cast, b) a verification index that confirmed the position of the analogues in the cast, c) a copy of the mandibular denture, or an impression of the existing conversion prosthesis. No articulator is required for the CAD/CAM design and manufacture of the milled framework. The design of the framework should take account of the position of the teeth and should address concerns of imposed function. In this case, the framework design utilizes an effective “Y” design to provide resistance to deformation and strength (Figures 10A-10B). The regions of the 30 Implant practice

framework distal to the screw access areas are bolstered to account for known stresses that accumulate in this area of cantilever bars. Note that the design is within the contours of the scanned denture and should not interfere with the prosthetic teeth. The distal inclination of the implants does not impede the use of simple abutments as these abutments possess 20º conus interfaces for the framework. In most cases, displacement of the implants leading to access screws exiting the first or second premolar region involves approximately 25º of angulation between the two implants and is easily reconciled by 40º of mutual angulation between two 20º conus interface abutments (Figure 11). There exists no need for an angled abutment component. There is no need to assess the fit of the framework due to the accuracy of manufacture and the provision of the verification index.
Upon delivery of the framework, it is transferred to the articulator and nanohybrid composite/PMMA teeth (SR Phonaris II, Ivoclar Vivodent) were arranged in baseplate wax for try-in and final evaluation (Figure 12A). In this particular case, one implant was placed facial to the anterior tooth plane. This is attributable to the conversion of a skeletal Class III relationship to a Class I dental relationship. One approach to solving the interference of the screw access with the esthetic aspects of the incisor tooth is to construct the acrylic veneer prosthesis with the denture tooth deleted from the position of the offending screw access during processing. This approach was taken in design and implementation of prosthesis construction (Figure 12B). Metal frameworks for implant-supported fixed dentures typically require opaquing of the metal color. This can be done using

different methods that include adhesive and non-adhesive application of materials. Another innovative approach is the anodization of the titanium alloy metal substrate to a pink hue (Figures 13A-13B). This technology is commercially available (AccuFrame® Plus, Cagenix™, Memphis, Tennessee) and was applied in this instance. Following tooth try-in and acceptance by the patient, the fabrication of the ISFD was completed by conventional processing that included tinting of the acrylic resin base using white, red, and melanin shading acrylics (Kayon® denture stain kit, Englewood, New Jersey). Just prior to flasking of the prosthesis, the lateral incisor tooth interfering with bridge screw access was removed from the wax-up (Figure 14). The interface between the tooth and the baseplate wax was refined, and then the waxed denture was finally flasked in plaster. The acrylic resin base and teeth were polymerized and de-flasked, and the prosthesis without the lateral incisor tooth was revealed (Figures 15A-15C). The lateral incisor tooth was easily fit to the recipient acrylic resin housing the screw access, and the entire prosthesis was finally polished.
Delivery and follow-up care The processed denture was delivered using four bridge screws tightened to 15Ncm. Prior to closing the screw access and placement of the lateral incisor tooth, an occlusal photograph was made and given to the patient. All hex bridge screws were covered with cotton pellets. The lateral Volume 9 Number 2

incisor tooth was fit into the recipient acrylic resin housing and bonded into place using ProTech Plus® self-cure hard reline and repair acrylic resin (ProTech Professional Products). The screw access hole exiting the pink denture resin was filled with pinkfibered triad resin (Dentsply), and the screw access holes exiting the premolar teeth were filled with shade A3.5 composite resin (Kerr, Orange, California). These surfaces were covered with Vaseline®, smoothed with a gloved finger, and then light polymerized in order to avoid polishing. The occlusion was verified using articulating paper visualization and bilaterally symmetric contacts in centric occlusion as demonstrated using shimstock (Figures 16A-16E).
Summary The use of conical-design abutments permits the intentional displacement of implants in nonparallel orientations without adding complexity (additional screws, specific angled components, or custom abutments) to the required components for restoration. The 20º configuration illustrated here offers resistance along the abutment/ prosthesis interface that contributes to stability of bridge screws. The use of CAD/CAM manufacture of frameworks does not preclude the use of individual abutments in construction. The placement of abutments of strength and utility enables the clinical management of the prosthesis at a tissue or supratissue level. IP

Dr. Shakeel Shahdad presents a clinical case illustrating replacement of a maxillary canine with a narrow diameter implant in a hypodontia patient
I
mplants are now considered a predictable choice to replace missing teeth; nevertheless, replacement in the esthetic zone remains a challenge. In addition to the challenges posed by the various clinical scenarios, our patients have high expectations; they demand optimal functional and esthetic outcomes. An ideal implant restoration has to re-create gingival esthetics, and for a clinician, the pink esthetics remain the most challenging aspect of the treatment. In recent years, we have become more critical in objectively assessing the outcome with newer indices. Furhauser and colleagues (2005) recommended the “pink esthetic score” (PES) as a means of objectively assessing gingival esthetics in implant restorations, especially single-tooth implants. Besides papillae, the PES combines the height, contour, color, and texture of the peri-implant soft tissues. Achieving an ideal esthetic outcome in implant restorations requires a meticulous approach. The different stages of treatment

Implant treatment in the esthetic zone
CONTINUING EDUCATION The UL3 was positioned in the UL2 space, and a pontic space was present in the UL3 area (Figure 1). A diminutive right lateral incisor was present. The overall dentition was minimally restored, and the pontic space mesiodistally was adequate for a canine width tooth (Figure 2). However, the interradicular space was limited and inadequate for replacement of this tooth with an average diameter implant, ideally suited for a canine tooth (Figure 3). After a detailed discussion, the patient ruled out a resin-retained bridge and preferred to have the tooth replaced with a dental implant. Direct composite buildup was carried out to optimize the diminutive right lateral incisor and reshape the UL3 as the UL2. A narrow diameter, tissue-level type, Straumann速 Roxolid速 hydrophilic implant (3.3 mm diameter NNC) was placed in an
ideal three-dimensional position for a screwretained single-tooth restoration. Submerged healing was allowed for 6 weeks followed by implant exposure surgery.

Conclusion
Figure 13: Radiograph at 2 years, demonstrating wellmaintained bone levels
While the success of osseointegration is now an established fact, the challenge for clinicians is to deliver restorations that esthetically fulfill the objectives of treatment. This clinical case demonstrates how careful assessment and treatment planning can be predictably controlled to fulfill the treatment objectives. A narrow diameter implant was used to replace a canine, which is now feasible to do predictably with the advent of stronger dental implant materials. Despite the non-ideal orthodontic result, the final esthetic outcome with the dental implant and reshaping of teeth with directly bonded composite restorations yielded a great result for this patient (Figures 10 and 11).

In brief: the sausage technique Dr. Istvan Urban explains the processes and concepts behind his innovative — and less invasive — approach to bone regeneration You are widely known for developing the “sausage technique.” Can you explain a little of the theory behind this procedure? Prior to the sausage technique, we had to utilize more autogenous bone blocks, which is a pretty invasive procedure. The sausage technique is minimally invasive compared to this, which is one of the biggest advantages. Now, we can utilize particulate bone graft composed of 50% of autogenous bone scrapings and a xenogeneic bone graft. So by mixing these two together, we need to harvest much less autogenous bone. One big advantage is that the xenogeneic bone graft maintains the volume of the regenerated crest, whereas the autogenous blocks tended to resorb over time, often meaning you had to repeat the procedure. We have more than 10 years of experience with this technique, which shows it is very stable. Why is it called the sausage technique? Well, simply put, it’s because we use a native collagen membrane, which we stretch out with mini-tacks to completely immobilize the bone graft. Using the membrane in this way, like a skin, looks like a little sausage and achieves a very stable bone graft. This membrane beautifully allows the blood vessels to permeate through from the periosteum and the host bone and will resorb in around 4 to 6 weeks. The term sausage technique is not a medical term; rather, it is a technical term to highlight to the clinician that immobilizing the bone graft with the collagen membrane is central to the technique.
How important are the properties of the materials that you use for this technique? They are very important. Let’s talk about the bone graft — Bio-Oss® (Geistlich) is the most well-studied graft material on the planet. It is very successful because it has

38 Implant practice
the structure of native human bone, which allows for connection between the graft and the host bone. The other important property is that it is dimensionally stable — it does not resorb too quickly. Allograft, for example, has poor dimensional stability, so we cannot use it for this technique. The membrane again is native and, again, is very well studied. We know from the research that capillaries from the periosteum can pass through the membrane, which allows for nutrient transfer and vascularization, but at the same time, it does not allow for the ingrowth of soft tissue cells. So it excludes what needs to be excluded and allows what is required for good bone formation.
You have developed a technique that uses a strip of autogenous tissue harvested from the palate, which sits alongside a strip of 3D collagen matrix to gain keratinized tissue. How does this work? We know that keratinized tissue (KT) is really important around implants, but developing it can be quite an invasive procedure. You have to harvest large quantities of soft tissue from the patient’s palate using a free gingival graft (FGG), which is painful for the patient, and often the outcome can be esthetically poor. I consider this new approach to be a little bit like tissue engineering: What we are doing is utilizing a collagen matrix, which is designed to stabilize the blood clot of the periosteal bed and allow the soft tissue cells of the neighboring tissues to migrate and to form within the matrix. If we just use the collagen matrix, we can get some KT, but sometimes we need more than 2 mm-3 mm — after bone grafting, for example, we might need 5 mm or more KT because the mucogingival line has been distorted. In these cases, we can harvest a very thin FGG, which is a source of cells, and position it apically to the collagen matrix — providing cell ingrowth into the collagen matrix. A big advantage of this technique is that harvesting this thin strip of autograft causes
only a negligible amount of pain — something that was observed in our study. Out of 20 patients involved in the study, 19 didn’t recognize the wound from the ministrip graft that was harvested from the palate, which is a very big improvement compared to the FGG, or connective tissue graft. The other thing we see is that since the matrix is collecting cells from palate and cells from the strip of autograft, it is more esthetically pleasing than the FGG. So we have less morbidity, less potential for bleeding, better-looking soft tissue, and very good attached KT. Now, in a new study — to be published soon — we can demonstrate using histology that we are really developing KT with this technique.
You have recently become a board member at the Osteology Foundation. Can you tell us a little bit about your role? For me, it is an honor to be a board member of the Osteology Foundation. I think it’s a great foundation, and the work on the communication committee is really exciting. The foundation already communicates well with dentists, and I think most dental practitioners know and like the major symposiums. But there is still room to develop and reach out to dental communities and communicate, not only through the symposiums, but also throughout the year. For example, if you have a group of dentists running a study club, the Osteology Foundation can support them with speakers, by helping to develop research protocols and ensuring they have a platform where they can communicate with each other, with the Osteology Foundation and with other study clubs. To have a platform where we could standardize documentation and make it easier to evaluate cases would be a big step and would help to promote education, science, and communication between dentists.
Can you tell me a little more about your involvement with this organization and your lecture at the symposium in April? I am lecturing on vertical ridge augmentation at the International Osteology Volume 9 Number 2

I will also talk about the completely resorbed maxilla and utilizing GBR to regenerate in a vertical and horizontal direction — which is very exciting because we are just publishing a study that shows 15 years of follow-up with Volume 9 Number 2

The X-Guide system utilizes the surgeon’s plan to provide turnby-turn guidance during live surgery, giving the ability to visualize precise movements of the handpiece during osteotomy and implant delivery for more exact placement — it’s like GPS for the drill. X-Guide is: • Impressively easy • Remarkably accurate • Incredibly consistent
“The X-Guide system fills the final gap of digital dentistry. Dynamic 3D navigation allows the dentist to use all the 3D digital information at their fingertips in real-time to immediately plan and place implants.” — Dr. Robert W. Emery, Diplomate of the American Board of Oral and Maxillofacial Surgeons

Best of three In the fifth article of his series, Toks Oyegunle looks at the three fundamental pillars of creating a winning marketing strategy
I
f we assume you want increased sales and profit from your dental practice, then what exactly must you do to create a marketing strategy that will help your business to thrive? Before we get into the strategy, here’s a quick recap: This is the fifth article in a six-part series developed to help dentists improve the marketing of their practices. In this series, I am using my “triple M” profitable marketing framework as a tool to clarify exactly what needs to be done to significantly improve your marketing efforts. Over the last few issues, we have delved into the details of this framework separately: What they are, how they work, and how you can profitably apply the framework to your practice. This article will present an overview of all the individual components and how they all fit together. The three basic aspects you need to understand and implement properly are market, message, and media.
Market Simply put, your market represents the universe of current and potential patients. However, who really represents your perfect target market? If we are unclear what we are aiming for, it will be difficult to hit the target! In line with this, I introduced the concept of the “perfect patient avatar”: a detailed

profile of the best patient you can attract to your practice based on the criteria you believe your patients should exhibit. The idea of the demographics and psychographics of your market was explored as a key component of the perfect patient avatar, as this is the only way you can truly understand your market. This detailed level of patient understanding is critical to you being able to attract the best patients effortlessly to your practice because you will know how they think and what they truly want from your practice and why. To understand your patients better, I suggested you analyze your patient database by separating them into three distinct groups: • Best patients • Average patients • Worst patients On one hand, this exercise helps you appreciate your best patients more and figure out ways to give them a delightful experience. On the other hand, it makes it very clear which patients need to be fired from your practice and why. Never be scared to lose problem patients — especially the ones you are sure that you cannot satisfy or convert to become your best patients. It will give you more time and energy to serve your best patients better — and that is always a good idea!
Message Your message is the core essence of your communication with your market. This becomes increasingly easier once it is clear
who your perfect patient is because you can intentionally craft your marketing message to speak directly to the patient’s wants and needs you have already identified. This is why we started by developing a “perfect patient avatar,” and I still strongly advise you to do this for your practice if you are serious about increasing your profit dramatically. Next, identify your unique selling point (USP). This is usually a phrase or sentence that clearly summarizes and explains the key benefits you provide to your patients over your competition. Think of it as a simple marketing message that you can use to communicate with a lead that will easily convert them into a patient. If you’ve not yet developed your USP, the following questions will help you: 1. What are your core strengths? 2. What are patients’ biggest needs? 3. What are patients’ biggest wants? 4. Why will patients choose you over others? Remember, your USP does not need to be cast in stone; it is a dynamic communication tool you will use to easily attract the right patients to your practice on a regular basis. The goal here is to create a message that makes you stand out in an already crowded marketplace. So, start now and put your USP together with the knowledge that you can always change it whenever you want.
Media I gave the following definition of media to ensure you are thinking about your options Volume 9 Number 2
results while decreasing/stopping adverts that do not bring results. You are a small business and simply cannot afford to do the big adverts that large companies do with little or no way to measure the effectiveness of your advertising spending. This testing process will take time, but once you get it right, you will be able to predict the response you will get from certain media with some level of accuracy. This is the feedback you need to plan your advertising investment accordingly.
Never be scared to lose problem patients — especially the ones you are sure that you cannot satisfy to convert to become your best patients.
The basic three
However, if you get this right, you should soon see considerable growth in the sales of your services and products. The following questions will help you to understand what media you should use for profitable marketing: 1. Who are your perfect patients? 2. What media do they use? 3. What media should you use? Once you decide on the ideal media for your practice, you need to test each option carefully by starting small and only increasing your adverts in the media where you get
We have clarified exactly what you need to do to increase your profit by improving your marketing, and it is captured by this simple formula: “Right market x right message x right media = increased practice profit.” Once you get your market right, your message right, and your media right, you will be shocked by the rapid transformation that will happen to your practice. Once you manage to get the three basics right, increased profit will happen naturally as you will be optimized for growth. IP

PRACTICE DEVELOPMENT
the right way: “Media — any platform that enables you to effectively communicate your marketing message and positively influence your target market.” Once again, I want you to take a moment to consider the many different platforms that you may use to communicate your marketing message and positively influence all the potential patients out there to come to your practice instead of the competition. We explored the different media options available to you in the market and considered the merits of some over the others. What is the right media for you to use for the profitable marketing of your practice? Do not underestimate the importance of this question; understanding what media to use, and why, will provide you with invaluable information regarding where you should regularly advertise your practice. It is probably the most important question you can ask regarding your use of media. If you get the answers wrong, you will probably incur considerable advertising costs with relatively few results to show for it. I am sure some of you have already had this experience.
ON THE HORIZON
Small diameter doesn’t mean small choices Dr. Justin Moody discusses his choice for small diameter implants
I
n the beginning of implant dentistry, clinicians’ only choices for small diameter implants were one-piece titanium implants of variable sizes ranging from maybe 1.9 mm to 3.2 mm. The downside to these small diameter, or what many refer to as miniimplants, was that they were one piece, which meant that they had to be loaded immediately. It was this lack of restorative options that kept many from using them and truthfully what caused them to get a
Figure 1: Zirconia hybrid abutment to a 3.0 BioHorizons Ti-Base created by ProSmiles Dental Studio
bad rap. The argument was so heated that online forums and discussion boards had to create second columns for the “mini” implant people. As time has passed, I have found myself placing narrower implants for preservation of buccal bone and soft tissue maintenance. Today is a different story all together as we now have 3.0 mm two-piece implant options with full restorative options and anatomically correct implant bodies; the tapered body allows for better positioning in the anterior for those missing lateral incisors and lower anteriors. This is significant as we can provide the patient with exactly what they need, not just what we can do, if we are limited by the implant or restorative options. We can elect to submerge the implant in a traditional two-stage procedure with a cover screw when the situation calls for it. When the need calls for immediate provisionals and loading, the 3.0 is well equipped to handle most any situation.
These implants are now included in most treatment planning software for use in case design and for fabrication of surgical guides. Cone beam CT machines like the Carestream 8100 3D allow for real-time virtual implant placement as well as easy integration with guide manufacturers like Implant Concierge™. How do you choose a small diameter implant? The BioHorizons® Laser-Lok® tapered internal 3.0 is my implant of choice. Not only do these implants have the LaserLok surface treatment that has shown great bone and soft tissue attachment, but with the reverse buttress thread design, they have amazing initial stability. When I looked at the full line of prosthetic products such as the ability to make hybrid abutments on titanium bases, stock esthetic abutments, and screw retained crowns, it was a no-brainer for me. As technology continues to advance, I’m looking forward to even more options for my patients and my practice. IP

The 3.1mmD Eztetic Implant is designed to offer improvements over similar commercially available implants, particularly in the areas of strength and primary stability. When compared to select competitive implants of similar diameters, the Eztetic Implant achieved a 43% higher fatigue strength.1 In addition, the implant performed exceptionally well in insertion torque and torsional yield strength testing.1 For the first time, three concepts have been combined to create a precise implant-abutment connection designed to reduce micromovement and microleakage. This unique connection consists of a conical interface, platform switch, and Double Friction-Fit™ technology designed to make strong narrowdiameter implants indicated for all anterior areas. The Eztetic implant-abutment connection, along with a Contour Abutment profile, is designed to provide space for soft tissue and esthetic emergence of the restoration. In addition, a wide range of userfriendly restorative options are available, including abutments for cement-retained, custom, and overdenture restoration.

Sani-Soak Ultra from Enzyme Industries Sani-Soak Ultra is an anticorrosive enzymatic cleaner that can be used as an ultrasonic cleaner and/or an evacuation system cleaner. Sani-Soak Ultra is designed to brighten and extend the life of instruments, is nontoxic, and is safe to use on burs and instruments. It is available in Cool Mint or Lemongrass Lavender scent. Sani-Soak Ultra is available in a quart or gallon bottle or a 64-count box of 0.5 oz uni-dose packets. The quart bottle has a built-in “tip and measure” cup, and it yields 64 gallons of cleaner. In an investigation, dental scalers and probes were heavily contaminated with organic soil prior to undergoing processing in an ultrasonic cleaner. The amount of challenge debris on instruments was far greater than what would be expected in clinical settings. After contaminated instruments were processed in an ultrasonic unit for 10 minutes, rinsed, and subsequently visually observed, it was found that Sani-Soak Ultra Enzymatic Cleaner System effectively removed the extensive dried material in >99% of soiled test samples.

DENTSPLY International introduces the CELTRA® DUO zirconia-reinforced lithium silicate (ZLS) Block DENTSPLY International Inc. is offering the new CELTRA® DUO (ZLS) high-strength glass ceramic milling block. The fully crystalized CELTRA® DUO (ZLS) block contains high-glass content and features a zirconia-reinforced lithium silicate microstructure, resulting in a balance of durability, translucency, and opalescence for a beautiful natural-looking restoration. In addition, CELTRA® DUO (ZLS) is the only material that can be processed in two different ways, providing the clinician complete control for each individual restorative case. CELTRA® DUO is a threefold functional zirconia-reinforced lithium silicate (ZLS) block indicated for single unit restorations, including crowns, inlays, onlays, and veneers. The blocks possess the unique capacity to be processed in two ways — either milled and polished, or milled and fired. This dual pathway component renders complete clinician control in determining the appropriate solution to apply for each individual restorative case. Moreover, CELTRA® DUO (ZLS) can be processed by dry fire, eliminating the need for glaze. The ZLS microstructure is composed of fine-grained lithium crystallites that contain high-glass content and an exceptional balance of opalescence, fluorescence, and translucency, resulting in a natural-looking yet exquisite restoration. Additionally, the 10% zirconia reinforces the glass matrix without clouding while yielding high flexural strength properties to provide a robust, easily polished block with detailed margins. CELTRA® DUO (ZLS) can be conveniently utilized with the same milling units used for all-ceramic restorations, including the inLab® MC XL.
