Implants Today

While implants have the mechanical availability to attach many different prosthetic options, many factors must be taken into consideration before a final prosthetic choice is made for the patient. The decision amongst the prosthetic choices available to attach to a implant is based upon treatment planning.

This month’s Implants Today topic is dental implant prosthetic options. This is a broad topic in the field of dental implants, one where we find that there are now many treatment choices for the patient. While dental implants have the mechanical availability to attach many different prosthetic options, many factors must be taken into consideration before a final prosthetic choice is made for the patient. The decision amongst the prosthetic choices available to attach to an implant is based upon treatment planning.

One of the first questions I ask patients is if they are open to wearing a removable implant-supported option. While a removable implant-supported prosthesis can be a more affordable than a fixed option, there are disadvantages to consider. The main disadvantage to a removable implant-supported prosthesis is that this choice is less like natural teeth than fixed options. Removable implant-supported options that are partially tissue-supported also are susceptible to bone loss in the tissue-supported areas and the inherent problems associated with any bone loss. Unless finances are the determining factor, in my experience I have found that most patients would rather have a fixed implant-supported option.

From a fixed prosthetic standpoint, it seems that fewer screw-retained acrylic hybrid options are now being chosen and utilized as a treatment option. The success rate of zirconia as a screw-retained option has increased the use of zirconia for full-arch implant-supported prostheses. Zirconia, especially as a monolithic option, reduces and virtually eliminates the problems of porcelain chipping and the loss of teeth from the prosthesis. While there might be slightly higher laboratory costs associated with the fabrication of a full-arch screw-retained zirconia prosthesis, these costs should be compared to the financial impact (and stress) for the clinician and patient that can result from fractured teeth seen often with acrylic and metal hybrids. There are other clinical benefits of zirconia versus acrylic. Zirconia, having the highest modulus of elasticity of any product available in dentistry along with its inherent low porosity and susceptibility to attract debris, allows for the observed high success rate with this prosthetic option. In addition to the cost of repairs, there is often a loss of patient confidence seen with hybrid acrylic bridges that can negatively affect the dental practice. Some thoughts when choosing among the different treatment options for a patient.

This month, we have 2 excellent articles in our Implants Today section. Dr. Edward Kusek presents an article showing the resurrection of a failing implant case using the latest technologies and clinical expertise, and Dr. Tim Kosinski discusses proper preparation for prosthetically driven implants and demonstrates the ways in which the latest technology, implant design, and techniques, can help the clinician manage a challenging case.

Narrow-Body Dental Implants

The Implant Practice

Implant Fixtures and Abutment Considerations

This month’s Implants Today topic is narrow-body dental implants. As the multibillion-dollar market for dental implants grows, many new companies are entering the market worldwide. Each company offers implants with different surface textures, connections, components, and sizes. The diversity of situations for clinicians placing implants mandates that different sized implants be made available. Patients vary in the height, width, and density of available bone required to place implants. Each size of an implant, in relation to the height and width, has a direct relationship to the components, connections, and surface textures, so there is a great deal of biomechanical engineering involved in the design and manufacturing process for an implant to be successful. All the fundamental design principles that the late Dr. Carl Misch used to speak and write about sum up what is needed to create a successful dental implant. When a doctor chooses to use an implant, the reasoning behind the design should be considered, and one must make sure the prosthetic components that are attached to the implant are available from the manufacturer. This is also true for high-tech reasons such as scanning jigs and Implant Stability Quotient (ISQ) scale readings with an Osstell meter, for example.

Choosing the correct size implant to treat edentulous areas requires a knowledge of hard- and soft-tissue biology, emergence profiles, and how this all relates to implant design. The advantage of narrow-body implants is that the needed spacing of 3.0 to 4.0 mm between implants, and 2.0 to 3.0 mm between teeth, can be obtained more easily with these available implant size options. The spacing of implants is one of the key principles for clinical success due to bone needing adequate vascularity to survive. Once bone is lost, so is the surrounding tissue with all the negative aesthetic and functional problems associated with that tissue loss.

The emergence profile around the implant must be considered, as well as its biomechanical strength. When replacing a molar, if the space is wide, an implant that is narrow might create a poor emergence profile, like a lollipop on a stick. In a full-arch case, I have used 3.4-mm implants in between 3.8-mm and 4.0-mm implants, but not to support the entire arch by themselves.

In our Implants Today section this month, we have 2 great articles related to narrow-body implants. Dr. Todd Shatkin et al’s “A Mini Dental Implant Alternative to All-on-Four” shows an alternative option to larger body implants using mini implants with a clinical protocol that has worked well for many clinicians. The article by Dr. Ahmad Soolari et al focuses on the correct use of a narrow-body implant to fill a lower mandibular edentulous space in a unique manner that fit the clinical situation at hand.

The Implant Practice

Implant Fixtures and Abutment Considerations

Tribute to Carl E. Misch, DDS, MDS, PhD (hc)

 

As dentists, we are all in one way or another involved with implants. The high success rate seen industry-wide with implants makes them the first choice for edentulous areas of the mouth for every practitioner. All dental specialists include implants as an option in interdisciplinary treatment plans when communicating with GPs.

One of this month’s Implants Today topics is the implant practice. As dentists, we are all in one way or another involved with implants. The high success rate seen industry-wide with implants makes them the first choice for edentulous areas of the mouth for every practitioner. All dental specialists include implants as an option in interdisciplinary treatment plans when communicating with general practitioners (GPs).

Any GP can choose to focus on implant treatment whether it be the surgical or prosthetic phases (or both). I recommend it; the decision to become involved with the placement and restoration of implants has been the best practice decision I have ever made. I enjoy the responsibility of, as the late Carl Misch said, “replacing millions of years of evolution that has failed.” I feel the awareness of that responsibility of replacing a natural event brings the needed respect that implant dental treatment commands. Once you choose to be involved with implant treatment as a practitioner, you will see how challenging it is (in a good way). Implant dentistry has been called a surgical discipline with a prosthetic component. This inter-relationship of surgery and prosthetics lends to a multitude of discussions and learning opportunities about many areas of dentistry. Dentists who wish to make implants a part of their treatment options need to be knowledgeable in aesthetic dentistry, occlusion, bone grafting, soft-tissue grafting, medical history, treatment planning, dental biomechanics, exodontia, orthodontics, and more. Being educated about every aspect of dentistry is what makes implant dentistry so enjoyable and engaging.

As the clinician gets more involved with implant treatment, especially the surgical aspects, the more involved the entire dental team must be. For me, running a practice with a strong surgical and prosthetic emphasis requires a true team effort. This month, we have an excellent article by Dr. Charles Schlesinger that addresses this issue. He emphasizes, amongst many other points, the importance of involvement by the entire team when delivering implant treatment. In my practice, this starts with the team members at the reception desk. When my receptionist takes a phone call from a patient asking about implant treatment, the call is immediately passed on to our implant treatment plan coordinator. The coordinator then determines the next steps that will eventually involve various dentists, assistants, hygienists, and more. I feel the entire team in an implant practice should be educated about all aspects of implant treatment. Team efforts are rewarding!

In another informative article this month, Dr. Barry McArdle discusses the clinical aspects of abutment design related to peri-implantitis. Clinical topics such as this and Dr. Schlesinger’s are all a part of learning about the implant practice.

The angle and platform height at which an implant is surgically placed can be corrected through various implant manufacturers’ components as well as by using custom abutments. Some implant companies have angle corrections built right into the implant fixture itself;
however, these require more exacting placement positions.

This month’s Implants Today topic is implant fixtures and abutment considerations. The choice of how a final prosthetic solution attaches to the dental implant(s) involves various factors and is a fundamental concept in implant treatment. The 2 main considerations for an abutment choice are (1) the angulations or platform height of the implant(s) and (2) the soft-tissue height around the implant(s).

The final prosthetic option, as determined by a properly prepared treatment plan, should dictate the positions and numbers of dental implants to support that prosthetic decision. This is called prosthetically driven implant dentistry. The abutment that connects the prosthesis with an implant can address the variability of a patient’s hard- and soft-tissue anatomy and is the buffer between a prosthetic goal and the patient’s hard- and soft-tissue anatomy.

The angle and platform height at which a im-plant is surgically placed can be corrected through various implant manufacturers’ components as well as by using custom abutments. Some implant companies have angle corrections built right into the implant fixture itself; however, these require more exacting placement positions. Multi-unit abutments are a way to correct the angle of an implant, allowing the screw hole to be redirected. Multi-unit abutments come in various angles and heights. The disadvantages of using a multi-unit abutment include the following: an additional microgap, increased costs, and a connection with the potential to loosen. Ultimately, ideal surgical placement should be performed to create optimal implant platform heights and angles based upon the desired prosthetic outcome.

The tissue height around an implant is also the result of the surgical technique used and correct treatment planning. If the ideal tissue height cannot be achieved after hard- and soft-tissue grafting and manipulation, then abutments can be used to bring an implant platform to a more coronal position. Ideally, an implant platform should be 1.0 to 3.0 mm below firm keratinized tissue. When an implant platform is more than 3.0 mm below the keratinized tissue, there is an increased propensity for soft-tissue problems and more pain with prosthetic try-ins. Ideally, it is better to achieve the correct platform height by employing correct surgical procedures than to gain that height through prosthetic parts (such as a tall multi-unit abutment).

In this month’s issue of Dentistry Today, we have a cover-featured article by Implants Today Advisory Board member, Dr. Jack Piermatti. Dr. Piermatti expertly discusses the details of different abutment choices in implant dentistry. Dr. Daniel Drake has contributed an article on the latest technologies in implant dentistry. Lastly, our editor-in-chief Dr. Damon Adams and I would like to announce the addition of Drs. Charles Babbush, Paul Fugazzotto, and David Little to our distinguished list of Implants Today Advisory Board members.

Bone Grafting for Dental Implant Placement

Listening to Carl lecture was not only educational but entertaining. He was humorous, answered questions quickly and accurately, and always exhibited total confidence. Every time I heard Carl lecture, it was always a different experience, even when the topic was the same. He was a gifted orator who made learning fun.

So many of our lives have been positively affected by Dr. Carl Misch’s presence on this planet. His passing early in January was a great loss to our profession and many will miss him dearly. I will remember Carl for the incredible positive impact he made on my career and in my life. I know I am not alone in feeling this way, because he had such an influence on so many of my colleagues and their patients. Carl exemplified focus, commitment, and passion for not only implant dentistry but also for dedication to excellence in life.

As I look back on his accomplishments during his 69 years, the breadth of his work is nothing short of amazing, with a CV that could be a book itself. Carl was a prosthodontic specialist with an implant certificate and master’s degree from the University of Pittsburgh School of Dental Medicine. The Misch International Implant Institute has educated more than 4,500 dentists and has been the primary educational venue for 6 dental school specialty residences with an ongoing physical presence in 9 countries. As a Fellow of the Misch International Implant Institute, I can personally say that this is one of the best educational venues for surgical and prosthetic dental implant training available anywhere. The reason, I feel, that the Misch Institute is so successful is the consistent principles that are taught, all based on Carl’s benchmark textbook Contemporary Implant Dentistry, now in its third edition, and on his book Dental Implant Prosthetics, now in its second edition. Contemporary Implant Dentistry has been published in 9 languages and is the go-to reference book for students taking their fellowship and diplomate exams with the International Congress of Oral Implantologists and American Academy of Implant Dentistry. Carl was also politically involved, honored, and a leader in all the major implant organizations.

Carl was not only an educator at his institute but was also a clinical professor and director of oral implantology in the department of periodontology at the Maurice H. Kornberg School of Dentistry at Temple University. Beyond that, Carl had lectured in every state in the United States as well as 47 countries. Listening to Carl lecture was not only educational but entertaining. He was humorous, answered questions quickly and accurately, and always exhibited total confidence. Every time I heard Carl lecture, it was always a different experience, even when the topic was the same. He was a gifted orator who made learning fun. In 2004, I had the honor to co-author with Carl one of his 250 articles, which was published in Dentistry Today.

I first met Carl in 1999, and when he signed his textbook and wrote “let the force/area be with you,” I knew I had met a special person. Eighteen years later, I can say my life has been enhanced by his presence on this earth and I will miss my mentor and am grateful for his gifts to all of us.

Dr. Damon Adams, our editor-in-chief, and our editorial team, who have all worked with Carl on numerous articles published in Dentistry Today, will sincerely miss this true icon in dentistry.

The aesthetic zone represents the center stage for implant placement. This is true in a patient with a high lip-line when smiling as all aspects of implant treatment are immediately visible to the patient and all others who may interact with the patient. Treatment in the aesthetic zone is even more scrutinized than other areas of the mouth.

This month’s Implants Today focuses on dental implants in the aesthetic zone. The aesthetic zone represents the center stage for implant placement. This is true in a patient with a high lip-line when smiling as all aspects of implant treatment are immediately visible to the patient and all others who may interact with the patient. Treatment in the aesthetic zone is even more scrutinized when compared to treatment in other areas of the mouth. For example, the steps for provisionalization are a crucial aspect of treatment since the type of provisional and shape of the provisional can help set up the emergence profile of an implant site.

Implant Site Development (March 2012, Wiley-Blackwell) by Drs. Michael Sonick (an Implants Today advisory board member) and Debby Hwang covers the concept of setting up sites for implant placement in depth. It also includes chapters by other prominent experts, such as Drs. Craig Misch and Scott Ganz (also advisory board members). I recommend this textbook because site development is so important; just like constructing a building, each foundational step sets up for the success desired in the final result.

The multidisciplinary topics that must be taken into account with implant treatment in the aesthetic zone include but are not limited to: soft-tissue site development, vertical and horizontal bone augmentation concepts, socket preservation materials, immediate versus delayed placement, the role of a CBCT scan, growth factors, provisionalization options, emergence profile and abutment considerations, soft-tissue biotype assessment, and implant spacing and depth. This is a true merging of surgical and prosthetic principles, as treating a patient for tooth replacement in the aesthetic zone requires a sound understanding of many principles that must come together for success. This is why I personally enjoy implant dentistry so much—there is so much to know and implement clinically. When you approach treatment with this kind of respect, treatment becomes a true passion as a clinician. Our patients’ lives are being changed and everyone benefits. This is certainly an endeavor worth pursuing!

While the principles for implant treatment success in the aesthetic zone are used in other areas of the mouth, the anterior region mandates that almost every principle be used. As Dr. Carl Misch said, “Don’t place your first implant on a central incisor in a patient with a high lip-line!” Learn dental implant principles in less demanding areas of the mouth while building expertise and clinical skills. Lastly, don’t just read and watch; step in and do it! The best way to learn is to do and to experience.

This issue presents an outstanding article by Dr. Michael Sonick et al that sums up the many aspects of success mentioned here. Also, Drs. Todd Schoenbaum and Chandur Wadhwani contribute excellent content that focuses on the screw-retained versus cement-retained restorative options in the aesthetic zone, and Dr. Dino Javaheri presents a simplified chairside technique for both temporary fabrication and impression taking.

Treatment Planning for Implant Dentistry

We would like to focus on the various CBCT-generated implant guides that are available and look at their advantages and disadvantages. A CBCT-based implant guide is a state-of-the-art concept that represents the highest aspects of implant technological advancements. 

This month’s section revisits guided implant surgical applications, a topic that will appear in each December issue. We will focus on the various CBCT-generated implant guides that are available and look at their advantages and disadvantages. A CBCT-based implant guide is a state-of-the-art concept that represents the highest aspects of implant technological advancements.

Of the 3 categories of guides available, tooth-supported guides for quadrant implant dentistry is the most predictable and simple of the guided implant scenarios. A tooth-supported guide has little room for error, as it is a hard-tissue-supported guide that is supported by teeth that are visible and accessible. This is different than a bone-supported guide, which is more complex surgically and more involved to create.

Soft-tissue-supported guides for full-arch implant dentistry are appropriate when the final full-arch implant-supported prosthesis does not required alveoloplasty. If alveoloplasty is required for prosthetic thickness or to hide the prosthetic smile interface, then a bone-supported guide is needed. A soft-tissue-supported guide can be used when extractions are being done concurrently at the time of surgery, but extractions can create complexities with a soft-tissue-supported guide. An example of extractions causing a complexity with a soft-tissue-supported guide is if extractions cause the ridge shape to change during the process, rendering an inaccurate fit of the preplanned guide on the ridge.

Bone-supported guides for full-arch implant placement are by far the most technically advanced guide in both the presurgical planning and during the procedure itself. Bone-supported guides in full-arch treatment require that aggressive flaps be done in order for the guide to fit. When extractions are being performed, in addition to alveoloplasty, the complexities are furthered. In the situation of extractions and alveoloplasty, these full-arch guides are either stackable guides or multiple guides. These advanced guides are, in general, associated with higher costs for the doctor and require more time to plan and have delivered to an office.

Another scenario that has become more popular as technology has improved, are the dynamic navigation systems based on motion tracking technology. There are a few systems available now for this that are FDA approved. The concept is to take a prosthetically driven plan from a CBCT scan, and then place the implants in the correct position freehand with the assistance of an on-screen program guiding with precise feedback. While there is a learning curve with this technique, the concept certainly offers some exciting potential.

Implants Today advisory board member Dr. Randolph Resnik offers an excellent article that exemplifies many of the points I presented here. Randy’s dual-scan technique shows an accurate way to represent the prosthetic end result on a CBCT scan. As time goes on, guided-implant surgery and its related technologies will become even more innovative.

Also featured this month, Dr. L. Stephen Buchanan addresses today’s need for general practitioners to learn how to start placing and restoring dental implants in their own office.

Bone Grafting for Dental Implant Placement

Treatment Planning for Implant Dentistry

The Future of Implant Dentistry

Everything related to implant dentistry involves a strong understanding of human craniofacial anatomy. To treatment plan, a clinician must have knowledge of anatomical concerns such as the sinuses and the locations of the mental foramens, the incisal foramen, the mandibular nerve....

November’s Implants Today topic is bone grafting for implant placement. If you are a dentist focusing on dental implants as a treatment modality, then bone anatomy, bone physiology, and bone grafting should be understood on every level. Every aspect of implant dental treatment—from treatment planning and surgery to prosthetics—is dependent upon the clinician having adequate knowledge about bone science. Even a medical history review is related to understanding many things about bone science. An example of this is the relationship between the osteoporosis drugs (bisphosphonates) and the risks of osteonecrosis. Understanding the science behind why there is a risk with respect to how bisphosphonates work, allows for an optimal medical history review and improved treatment planning with the patient. This is just one example of many that justify the importance of a good understanding of bone science on the part of the clinician who places implants.

Understanding Bone Anatomy and Physiology
It is important for the clinician to have a strong of understanding bone anatomy and physiology. Everything related to implant dentistry involves a strong understanding of human craniofacial anatomy. To treatment plan, a clinician must have knowledge of anatomical concerns such as the sinuses and the locations of the mental foramens, the incisal foramen, the mandibular nerve, the infraorbital foramens, and much more. As I reference in many of these editorials throughout the year, a CBCT scan is imperative for the true understanding of anatomical relationships and pathology. The patient’s anatomy dictates both bone grafting and implant placement surgery. Understanding bone physiology is also important. When placing a bone graft material into an extraction site, or to graft the lateral wall of a ridge, the clinician should understand the physiological process that is happening at the site. Through understanding the actual process, the clinician can make the right surgical and grafting material choices. When a clinician chooses a graft material, that choice should be based on the size of the defect. The larger a defect is, the more osteoinductive properties a graft should have. Through understanding that defects with less walls of bone have less vascularity, the choice to use autogenous or an alloplastic bone would be made. This shows how knowledge of both bone anatomy and bone physiology is important and how they both interrelate.

Grafting Quadrant Dental Regions
Not only is gross anatomy important, but understanding the soft- and hard-tissue anatomy of different regions of the mouth is as well. An example is the anterior maxillary region versus the posterior mandibular region. The anterior maxilla is the most demanding area to graft in the mouth. If there is 2 mm of papilla loss in a patient with a high smile-line, it could affect the entire case. That 2 mm of papilla height loss can be associated with extraction technique, implant spacing, soft-tissue concerns, and more. Successful bone grafting is also related to knowledge of prosthetics. In the anterior region, ovate pontics at the time of grafting can create improved hygiene and aesthetics.

The posterior regions of the mouth create challenges other than aesthetic concerns. In the maxillary posterior region, the sinus is the main concern and how to manage it when grafting. Both lateral wall sinus grafts and osteotome lifts are common ways to graft for implant placement. These could occur during implant placement or may be staged before, depending on the case. In the mandibular posterior regions, the mandibular nerve is the dictating factor. In general, both the maxillary and mandibular regions are anatomically wide due to the ridge size. The width of the ridges affects the choice of graft materials and membranes that might be needed. As with all bone grafting, the blood supply is an important consideration.

Grafting in Relation to Full-Arch Treatment
When a full arch is being treated for tooth replacement, the considerations are different than with quadrant grafting and implant placement. The prosthetic choice for the full-arch treatment plan dictates the grafting protocol. If the treatment plan is for a screw-retained prosthesis that has pink gingiva (Misch fixed prosthesis 2 [FP2] and FP3) then, more than likely, the clinician will be reducing the height of bone and grafting in any extraction site defects. This is because adequate prosthetic height is needed and in the maxilla the high smile-line should hide the gingival prosthetic junction. When the prosthesis doesn’t require a pink gingival area (Misch FP1), then bone is not taken away but instead grafted to be maintained or increased. Different prosthetic choices dictating the grafting treatment plan.

Featured Articles
This month, Implants Today advisory board member Dr. Craig Misch presents an outstanding article that shows how advanced the science of bone grafting has become. Craig is both an oral surgeon and a prosthodontist, and as a dual specialist, his article brings out many key concepts that are involved with bone grafting and implant dentistry. The tissue engineering advancements that he presents, tied in with advantages of an autogenous bone block, show a true blending of concepts. Between what has been presented above, and the excellent content of Craig’s comprehensive article, the reader can begin to grasp how successful interdisciplinary bone grafting is.

Also this month, Dr. Ahmad Soolari and Mr. Amin Soolari exemplify the principles of the need to graft bone to support implant placement. This article also shows the clinical choices of grafting materials, membranes, and the timing of an implant case.

Treatment planning is about communicating treatment recommendations clearly to a patient. Unless the doctor and team are united in a common direction and culture, the many facets of presenting a treatment plan may not appear to be coordinated, and therefore, will not be as effective to a patient.

This month’s Implants Today topic is treatment planning for implant dentistry. Of all of the topics we revisit each year, treatment planning is the most important, since it requires a combination of practice management and clinical disciplines. It is the starting point of many things that affect our patients’ lives.

THE IMPORTANCE OF A MISSION STATEMENT
When a dentist treatment plans an implant case, whether it is one implant or an entire arch, there are many clinical decisions and core individual philosophical opinions behind the plan. I believe a clinician should have a core practice vision, also known as a mission statement, that backs up any presented treatment plan. This vision statement defines the goals and culture of the dental practice, and from that vision statement, all interactions with a patient are driven. The reality is that most dental practices do not have a written vision statement. The reason for that is perplexing, as the concept of setting goals, writing them down, and committing to a vision statement is recommended in almost every New York Times best-selling leadership and business book. As dentists, we are running a business, and the core philosophy of having a vision statement for your dental practice for success is ubiquitous to all businesses.

A mission statement is not just about the bottom line of your practice. It is about representing your personal vision as a committed statement that affects your employees, your treatment decisions, and ultimately the business as a whole. I believe patients can sense the culture of a dental practice when they first call the office and again once they arrive. The vision statement and practice culture sets the tone for everything that occurs in a dental practice. Think about the vision and culture of the Ritz Carlton Hotel chain, or Lexus as a car manufacturer. These companies are both committed to excellence, and everything that they do, from their products to customer services, represents their vision and mission statements. Their visions create choices such as the quality of the towels Ritz customers touch to the leather the Lexus customers sit on. As a dentist, having a defined vision will translate to the front desk employees’ communication skills, to the efficiency of clinical care, and even to the quality of materials a doctor chooses to use on his or her patients. I believe that without a strong vision statement, treatment planning will not be as effective. Treatment planning is about communicating treatment recommendations clearly to a patient. Unless the doctor and team are united in a common direction and culture, the many facets of presenting a treatment plan may not appear to be coordinated, and therefore, will not be as effective to a patient.

Treatment Plans Solve Problems
Our patients usually come to us with a problem needing a solution. The problem could be replacing failing teeth or replacing missing teeth. We are honored with that responsibility and should appreciate the vulnerability of our patients’ feelings as they come to us for help. There are many subliminal background factors involved when we communicate our treatment plans with the goal of a patient accepting and also affording that treatment. A vision statement, which is put in writing and committed to, is the backdrop behind the implementation of every treatment plan given to a patient. When presenting a treatment plan, there are many facets to consider: clinical decisions, material choices, staff involvement choices, technology choices, and office environment choices that directly affect your patient’s life. Behind all of those components are marketing decisions for your practice that help bring that patient in for treatment. Again, I recommend that every dental practice, whether an implant-focused one or not, define their practice with an individualized, written vision statement that incorporates the identity of the practice and owner’s core beliefs.

A practice vision statement affects many aspects of attracting patients and treating them. This starts from the first contact a patient has with a dental practice. This could be the front desk staff or an advertisement a patient may have seen. A vision statement of excellence, appointed by the leader (owner) of the practice that a staff collectively commits to, will affect the decisions that shape advertisement choices and staff dialogue that helps a patient choose a dental practice for his or her treatment. This vision statement also affects the patient’s experience after arriving at the practice.

A vision statement might incorporate a focus of providing the latest technology in a practice. That commitment directly affects the quality of treatment. I have often highlighted the important role of technology with respect to ideal implant treatment in these monthly Implants Today introductions. Choosing the latest technology is based on core choices. This directly affects treatment planning. For instance, having an in-office CBCT machine has many benefits to both treatment planning and actual treatment. In my practice, I see a higher treatment plan acceptance rate since we often take a CBCT at a patient’s first implant treatment visit. By doing this, I feel a patient shows his or her level of commitment to treatment, as well as my commitment to being current and state of the art. This means a lot to patients, as they are making financial decisions and are feeling vulnerable.

Core practice visions should also incorporate scheduled communication between staff and the practice leaders. When a dental team is well coordinated with respect to communication of a proposed plan and practice values, there are many benefits. First, the patient is more likely to accept treatment. Beyond that, all informed consent forms are adequately presented, the financial arrangements are clearly communicated, and in the end, there is increased medical legal protection and reduced problems as a case is planned.

Standard operating protocols (SOPs) should be established with all aspects of patient communication and treatment. A leading dental consultant, Dr. Bill Blatchford, often recommends checklists similar to what an airplane pilot does. SOPs and good staff communication through scheduled meetings, as well as defined coordinated staff roles, creates an ideal treatment plan presentation for a patient. I have found, once again, in my practice that presenting implant cases and following up on the plans are best done with a team. My practice incorporates a philosophy of having me, as the implant surgeon, build trust and confidence with the patient, then having my clinical assistants and financial treatment coordinator follow up with the details. It makes sense from a practice management standpoint. None of this happens by chance; it has to be preplanned through core practice vision commitments.

This month, one of our Implants Today advisory board members, Dr. Scott Ganz, presents an article entitled “Enhanced Diagnosis and Treatment Planning for Implants.” This article exemplifies the principles outlined in this introduction by demonstrating how a commitment to excellence in technology and continuing education translates to ideal treatment planning. Scott’s commitment to providing the absolute highest level of CBCT-based treatment results in his patients receiving the best care possible. This month’s other offering under the topic of implants is by Dr. Rick Winter et al and describes a multidisciplinary case that demonstrates how to treat a patient with a severely atrophied mandible, vastly improving the patient’s function and self-esteem.

CLOSING COMMENTS
If you hoped to read this introduction and see more clinically based treatment planning steps, then I might have disappointed you. My intention was to use this venue to share core concepts behind those clinical steps. Our goal as implant dentists is to provide clinical excellence; however, without a core plan to communicate those clinical steps, financial steps, appointment steps, follow-up hygiene steps, etc, those clinical steps may either not be chosen by the patient, or miscommunications could hamper a great treatment experience for the patient, thus creating possible subsequent patient relation issues.

In summary, treatment planning is done from a core practice vision that is created by the clinician as a leader of the practice. As a leader who has created a solid written vision, your treatment team will then help your patients who are looking for the best solutions to their clinical problems get the ideal treatment they deserve. Treatment planning, as I have laid out, involves so many things. Under your direction and leadership, everyone involved, from the team to the patient, will benefit.

As clinicians, we are replacing teeth that have evolved and changed throughout thousands of years. Maxillary molars, for example, have 3 roots instead of 2, because the bone is softer and the forces are greater in the posterior of the mouth.

It has already been one year since the Implants Today section was first published. I want to thank Dentistry Today’s editor-in-chief, Dr. Damon Adams, for the invitation to be the editor of the implant section and for fostering a shared vision between us for this exciting new content. The support and encouragement of the entire editorial team and the positive feedback from our readers are also very much appreciated. I would also like to acknowledge and thank all the members of our world-class Implant Advisory Board who, during the past year, have contributed excellent and clinically relevant articles aimed at the GP reader. It takes dedication and a lot of time to write a quality clinical article and, through those efforts, Dentistry Today has been able to offer an abundance of solid information this past year that should have the potential to make a positive impact on your practices and patients. Damon and I would also like to encourage our clinician readers to submit implant articles to Dentistry Today for editorial review and, if accepted, publication. When our readers and colleagues contribute interesting clinical case report articles, a culture of shared knowledge is created. It is this concept of shared knowledge upon which our editorial content in Dentistry Today was founded.

The “Future of Implant Dentistry” was the inaugural topic last September. This, along with the other 11 topics that were covered throughout the year, will be revisited each year. By revisiting the specified topics that cover the many aspects of implant dentistry, a fresh annual retrospective can be realized. Implant dentistry is an evolving discipline and, through re-examining, these same well-rounded topics and fresh perspectives can be presented. With our potentially content-rich topics, such as guided implant surgery, implants in the aesthetic zone, implant overdentures, cone beam CT (CBCT) for implant dentistry, and 8 other exciting implant-related topics, new information will be updated and discussed each year.

The future of implant dentistry continues to be exciting, evolving, and more predictable. The dental implant industry a billion-dollar enterprise that is supported by improved materials, technologies, and various clinical procedures every year. I would like to look at the future of dental implant treatment with the grounding perspective of first looking at the past. As clinicians, we are replacing teeth that have evolved and changed throughout thousands of years. Maxillary molars, for example, have 3 roots instead of 2, because the bone is softer and the forces are greater in the posterior of the mouth. Cuspids have longer roots to support the forces of occlusion in extrusive movements. Through this historical and evolutionary perspective, one can appreciate any future progress with dental implants with respect of the daunting task and responsibility at hand. Dr. Carl Misch has been speaking on this perspective for many years. The future of successfully replacing what nature has created—and then sometimes fails—with implants requires the latest technologies, techniques, materials, and continuing education (CE).

FUTURE TECHNOLOGIES
As computer technology advances, there is a direct impact on implant dentistry and the potential for increased success. There are a growing number of companies that offer CBCT machines and software planning programs. Better resolution, faster scans, and the availability of virtual planning are examples in the arena of technology improvement. More sophisticated Internet technology at higher speeds has allowed clinicians and laboratory teams to share treatment planning information and to foster better collaboration among clinicians as well as those professionals representing different specialties who work together on the patient’s behalf. CBCT scanning and associated CAD/CAM technologies can now be used to plan and mill an entire case, with digital files following the surgical positions all the way to the provisional and final prosthesis. This is true for both quadrant implant dentistry and full-arch replacement teeth. The technological advances to measure the initial and post-integrated stability of dental implants have also impacted the success of treatment. The Implant Stability Quota (ISQ) measures the true bone-to-implant contact, as opposed to the perceived torque value. Through having an ISQ reference number, clinical loading decisions can be made with an objective value behind them. This information is especially useful for decisions related to immediately loaded implants.

Intraoral scanning technologies have evolved to a level that can totally replace manual tray impressions with dental implants. A digital scan of an implant requires an appropriate impression coping that correlates to the appropriate implant system library. Currently available scan copings are affiliated with closed systems specific to an implant company. In the future, open digital impression systems will allow for more dentists to utilize this technology. Once a digital intraoral impression is made, that information can be used to design a custom abutment, the provisional, and final crowns. Through digital intraoral scanning, the entire workflow can be digital with great accuracy. Models that are either CAD/CAM milled or 3-D printed can be used. The availability of chairside box scanners allow a clinician to scan a prosthetically approved full-arch bridge provisional so that a zirconia duplicate can be milled as the permanent restoration. Box scanners have substantially reduced in price and size of the units, making them easier for clinicians to obtain.

FUTURE TECHNIQUES
Surgical and prosthetic techniques for implant dentistry are closely related to technological advances as well as materials and CE. When a clinician adapts a new technique for implant treatment, it is often tied into advancements in other areas of implant dentistry. Immediate loading of dental implants is an example. Through advancements in implant design, and the availability of measuring implant stability with an ISQ reading, immediately loaded implants have become more predictable. As immediate loading becomes more mainstream, there will be more case studies upon which to grow our knowledge base, then to share that information through educational venues.

Another example of a technique that is based on technology is the increased use of growth factors in everyday implant treatment. Years ago, it was expensive and cumbersome to obtain platelet growth factors. Now, via technological advances and the ability to share information, platelet-based growth factors, such as platelet-rich plasma and fibrin, can be obtained and processed in a simple and inexpensive manner. Many other techniques are trending with the advancement of implant dentistry: conservative sinus grafting techniques, extraction techniques, soft-tissue grafting, and hard-tissue grafting are all areas that have evolved and will continue to do so, from technology, materials, and advancements in education.

FUTURE MATERIALS
Implant dentistry is a material-oriented discipline. From the implant itself to prosthetic parts, materials impact the success rates of implant treatment. In the past few years, there has been a trend toward innovative implant designs to help stabilize hard and soft tissue around implants. There are more choices from implant manufacturers as far as different heights and widths of implants. Manufacturers have offered an increase in shorter implant options in the past year, due to material designs and time-tested proof of success in the industry. Materials are also partially dictated by demand, with manufacturers listening to trends in the industry.

Zirconia continues to increase in the implant industry as a material for both implant design and prosthetic options. There are now 2-piece zirconia implants available allowing for 2-stage options and increased clinical applications. Major implant companies are also starting to create zirconia implant options, showing a trend and a real presence of increased use of zirconia in the implant world. CAD/CAM technology, which has led to the creation and use of zirconia implant bridges and crowns, continues to grow. In addition, there is a trend toward increased acceptance of zirconia, as this material shows continued success as a prosthetic option. There is also an increase in the use of 3-D printing for provisionals and models, as this technology has demonstrated increased accuracy during the past few years, while becoming more affordable. This also ties into the trend of a total digital workflow. There is even a milled-then-sintered metal option that is awaiting US Food and Drug Administration approval and should be available soon. This would further simplify designing and creating metal bars for smaller laboratories.

FUTURE EDUCATION
The collaboration of clinical experience based on technology, materials, and techniques is really what the future of implant dentistry is grounded upon. The sharing of information in journals, courses, and online is where true growth in this industry occurs. With digital technologies advancing, this will become even more prevalent and will assist the growth and success of implant dentistry as time goes on. Webinars, online planning sessions, and live online telecasts are just a few venues available for implant education. The many online education groups such as Dental XP and VuMedi offer thousands of hours of CE that were not available just a few years ago. Technology has also increased the quality of these presentations, allowing for an even higher level of quality education. Online planning and case sharing are also becoming mainstream, even furthering treatment planning collaborative efforts. All of this exchanging of information will propagate growth in the implant field, and I believe this will exponentially increase as time goes on.

This month, Implants Today Advisory Board member Dr. Natalie Wong’s article exemplifies the future of implant dentistry and how the collaboration of technology, materials, and techniques can create excellence in dental implant treatment. The guided case presented truly shows how advanced the industry has become, where a digital plan is physically implemented based on milled guides and a pre-created provisional restoration is delivered at the time of surgery.

It is from the publication of excellent cases like these that clinicians from all over the world can share and learn about the latest technology, techniques, and materials to further advance the future of implant dentistry. Here at Dentistry Today, we envision this collaboration of science and technology only increasing and leading to even more predictable implant treatment for the future.

CBCT Planning for Implant Dentistry

Dental Implants: Prosthetic Options

 

Since its invention and the ability to look at the human body in a 3-D perspective, advancements have made it practical for clinicians to either own a CBCT or have access to a mobile CT unit. Scan times and radiation levels have decreased, making CTs safer and more practical to have in a clinical setting.

This month’s Implants Today topic focus is on cone beam computed tomography (CBCT) planning for implant dentistry. In 2012, Implants Today Advisory Board member Dr. Scott Ganz and I authored a 3-part article series in Dentistry Today entitled, “The CT-Based Team Approach to Care” (Part 1, Part 2, Part 3). This series discussed how treatment planning, surgery, and prosthetics relate to a CBCT scan and the team approach. I bring up that article series to remind us how important CBCT has become for every aspect of implant dentistry including treatment planning, surgery, and prosthetics. In the time since the its inventors, Hounsfield and Cormack, received the Nobel Prize for Medicine in 1979, CT technology has greatly impacted implant dentistry and is a large part of the current success with dental implants.

Since its invention and the ability to look at the human body in a 3-D perspective, advancements have made it practical for clinicians to either own a CBCT or have access to a mobile CT unit. With multiple CBCT companies in competition with one another, the scan times and radiation levels have decreased substantially and the size of the CT units have all decreased during the past 37 year as well, making CTs safer and more practical to have in a clinical setting.

TO BUY OR NOT TO BUY?`

I am often asked for advice on which CBCT machine to purchase, and if a practitioner can support the costs involved and realize a decent return on investment (ROI) from the CBCT equipment. Choosing the right CBCT machine for a dental practice is a decision that mandates investigation of the style and size of the unit, ease of operating features, cost, associated software, and how fast the unit could be serviced, if needed. These are all somewhat subjective considerations, dependent on each clinician’s situation. Only after through research can that decision be made; doing this research will educate the clinician on many levels to ensure that the right choice has been made, making it easier to introduce this new technology into the practice and to patients.

So, how does a clinician know if a practice can financially support a CBCT machine, or if it would make more sense to utilize a mobile CT unit that comes directly to the dental facility after making an appointment? The answer to that is based upon various considerations, with the most important being: “Where does the clinician want to be in a year or so, from a vision standpoint?” If one has a vision to do more implants, and the clinician has the skills to perform implant dental treatment, then an on-premises CBCT machine has a high potential to make a positive ROI. One should know that the ROI for a CBCT machine is not calculated as simply as how many CT scans are being taken and how much a clinician is being paid for the scan itself. The immediate information to which a clinician can have access, and discuss with a patient by having a CBCT machine right on premises, offers many benefits that are sometimes overlooked when looking at ROI. As an example of the efficiency brought to the table by having this technology readily available, a CBCT can be taken on a new patient and the clinician can then review the information and offer a treatment plan at the first visit. It is not only impressive to the patient but also offers a large convenience factor. In my practice experience, having an on-site CBCT has led to an increased treatment acceptance rate.

There are other clinical advantages that can make having an on-site CBCT a good choice. In my practice, we often take a post-extraction CBCT before immediate implant placement, either in a full arch or in a quadrant. Having a CBCT machine on the premises allows for immediate placement of implants with CBCT guidance. Although a mobile CBCT unit could provide the same result, it would be logistically more cumbersome. Another clinical advantage of an on-site CBCT are follow-up CBCT scans on bone grafts, pathology, and complications. Having an on-site CBCT for these purposes offer many advantages to a practice.

CBCT Scans Routinely in Implant Dentistry: The Standard of Care?

In my opinion, a CBCT scan should become the standard of care for implant placement. There is not yet a full consensus among dental implant experts that use of a CBCT in implant dentistry is the standard of care. While many dental implants can be placed successfully without a CBCT scan, if there is a complication, a clinician could be asked why a CT was not taken. There is really not a defendable answer, since mobile CBCT units and other CBCT machines are now so readily available. I simply do not believe a clinician should take the chance of delivering implant dentistry without the detailed information that CBCT technology provides.

Furthermore, I also believe that there is no area of the mouth of which a clinician can justify that a CBCT should not be taken. The inferior alveolar nerve in the posterior mandible can be identified in CBCT software programs so that it can be properly avoided. A CBCT scan in the posterior mandible can also identify the angulations of the lingual wall so as to avoid perforations. The information offered in the CBCT scan can be utilized with either a guided or nonguided approach. In the posterior region of the maxilla, a CBCT scan can offer information to the location of the sinus wall, allowing the clinician to utilize osteotomes or lateral wall grafting, as indicated. In the process of making the most educated decisions possible, a panoramic radiograph does not offer the detailed information that CBCT technology provides. The anterior mandible presents many challenges that a CBCT scan can help navigate. A CBCT scan in the anterior mandible can not only help avoid lingual cortical plate perforations, but can also help prevent many other prosthetic and surgical complications. The anterior maxilla offers many challenges for the clinician, as the final prosthetic result is visible in most cases, depending on the patient’s smile-line. Bottom line? Having a CBCT scan for evaluation in the anterior maxilla can help avoid a multitude of prosthetic and surgical complications.

Professional Evaluation of the CBCT Scan

Once a CBCT scan is taken, I recommend that an evaluation of the CT scan is done with a formal report by a board-certified radiologist. It once again negates any risk of missing pathology on a scan that one, as a clinician, is (or may be) responsible to see and relay to a patient. After utilizing radio­logy reports as a standard for many years, I have seen many pathological situations that I would not have found on my own. These include carotid artery blockages, tumors and cysts in the cranial area, airway issues, vertebral pathology, and more. The minimal fee for the radiology report is justified in my opinion, and it is a real plus simply for peace of mind. Most dentists are not educated enough in the arena of radiological findings and interpretation to match the training and knowledge of a radiologist.

DICOM Data: CBCT Software Programs

The Digital Imaging and Communications in Medicine, or DICOM, data from a CBCT scan must be read by a CBCT software program for planning and diagnosis. Most CBCT companies have a resident software program that is part of the CBCT purchase. There are also independent company software CBCT programs that are more robust than standard software programs and come with a CBCT purchase. These “after-market” programs that read the DICOM data can offer advantages such as accurate anatomic implant placement on the program, advanced nerve mapping, improved detail 3-D mapping of prosthetic structures, portals to order surgical guides, and more. It is an advantage for a clinician to be able to utilize the CBCT software program in planning an implant case. Adept utilization of a CBCT program allows the clinician to offer a patient valuable and immediate information.

CLOSING COMMENTS

It is clear that CBCT scans are the backbone to successful dental implant treatment. I find this topic extremely important in the realm of implant treatment. CBCT scans offer an advantage to success for implant placement in every area of the mouth, for single implant placement or full arch and for bone grafts. As a clinician involved with implant dentistry, I recommend you embrace this technology that is safe, accurate, and offers a substantial tool toward successful implant treatment for patients.

ARTICLE LINEUP

This month, we have selected exceptional implant articles for our readers. Dr. Ara Nazarian presents a full-arch cement-retained zirconia implant case in which CBCT information played a vital role. Ara utilized information/data from CBCT scans to create 3-D models and surgical guides. The process that he showcases demonstrates the ultimate in the utilization of the CBCT process using digital technology to ensure a predictable prosthetic success.

Implants Today Advisory Board member, Dr. Michael Scherer, also presents an excellent article that shows how a CBCT scan can be used to plan for an overdenture case. This further shows how CBCT scans translate to success when executing both removable and fixed implant prosthetic options.

I have also authored an article on CBCT scans related to full-arch implant restorations. This article incorporates many of the principles mentioned in this section and it is my hope that it helps stress the points introduced above in this month’s introduction to Implants Today.
