These are but a few of the pearls found in this year’s beautifully produced annual resource for the dental technician and restorative clinician.

Surgical Management of Maxillofacial Fractures

Yoh Sawatari

The facial skeleton is comprised of vertical and horizontal buttresses and the intersections they create; maxillofacial fractures occur when these buttresses sustain more force than they can withstand. The objective when managing these fractures is to reverse the damage that these buttresses sustained and restore appropriate facial dimensions. Not all fractures propagate in the same pattern, so surgeons must compartmentalize the face and define the character of the individual bones. This book approaches the face one bone at a time, outlining how to evaluate each type of fracture, the indications for surgery, the surgical management, and any complications. Specific protocols for clinical, radiographic, and CT assessment are included, as well as step-by-step approaches for surgical access and internal reduction and fixation. Isolated fractures are rare with maxillofacial trauma, and the author discusses how to sequence treatment for concomitant fractures to ensure the most successful outcome. This book is a must-have for any surgeon managing maxillofacial fractures.

The Oral-Systemic Health Connection: A Guide to Patient Care, Second Edition

Edited by Michael Glick

As the oral-systemic health connection continues to be the focus of an overwhelming amount of scientific literature, it is important for dentists to stay informed in order to be a reliable source of information for their patients regarding both oral and overall health. This second edition of The Oral-Systemic Health Connection: A Guide to Patient Care explores the connections between oral infections and systemic diseases/conditions, incorporating feedback from scientists, practitioners, and policymakers. In addition to updated chapters about cardiovascular disease, diabetes, inflammation, and adverse pregnancy outcomes, authors have contributed new chapters about antibiotic prophylaxis, the genomic connection, common risk factors, and the economic impact of this connection. Because interpreting this research can be challenging, new chapters about causal frameworks and biostatistical assessment have been added, and specific clinical considerations for providing dental care to patients with certain conditions have been included in selected chapters. Besides providing readers with up-to-date information on the complex connection between oral and general health, this book prepares oral health care professionals to critically read and evaluate new research to ultimately benefit their patients’ overall health.

Next-Generation Biomaterials for Bone & Periodontal Regeneration

Edited by Richard J. Miron and Yufeng Zhang

New and innovative biomaterials are being discovered or created in laboratories at an unprecedented rate, but many of them remain entirely foreign to practicing clinicians. This book addresses this gap in knowledge by summarizing some of the groundbreaking research performed to date on this topic and providing case examples of these biomaterials at work. The book begins with a review of the biologic background and applications of bone grafting materials utilized in dentistry. The principles of guided tissue and bone regeneration are covered in detail, including many recent advancements in barrier membrane technologies as well as use of platelet-rich fibrin and various growth factors, and many next-generation materials that will optimize future bone and periodontal regeneration are presented. The final chapter is designed to help clinicians select appropriate biomaterials for each specific regenerative protocol. Much like one implant size and shape cannot be utilized for every indication in implant dentistry, one bone grafting material, barrier membrane, or growth factor cannot maximize regenerative outcomes in all clinical situations. This textbook teaches clinicians how to utilize biomaterials in an appropriate, predictable, and evidence-based manner.

The Sinus Bone Graft, Third Edition

Edited by Ole T. Jensen

As research proceeds on treatment of the resorbed posterior maxilla, new techniques and innovations continue to be adopted to solve this clinical problem. While the previous edition of this book provided detailed information on the types of grafting materials and procedures available at the time, this completely revised version looks to the future with new strategies for treatment, some of which avoid grafting altogether. This book not only reviews the time-tested lateral window approach for sinus elevation and grafting but also describes a variety of techniques to approach the sinus transcrestally with or without grafting material. One section of the book is devoted entirely to the different types of implants and implant placement techniques available, many of which are designed specifically to avoid sinus elevation. In addition to clinical case studies and descriptions of how to perform specific surgical procedures, this book includes discussions on the science of bone formation and how continued research brings us closer every day to the ultimate goal of using tissue engineering to completely regenerate new teeth.

The Ortho-Perio Patient: Clinical Evidence & Therapeutic Guidelines

Edited by Theodore Eliades and Christos Katsaros

Although most orthodontic curricula provide courses on interdisciplinary orthodontic-periodontic treatment, there are still surprisingly few resources on the topic. Written by leading scholars in the field, this book provides a broad analysis of the topic from both the periodontal and orthodontic perspectives. The authors systematically analyze the scientific and clinical interactions of these specialties by reviewing all the available evidence and using case studies to demonstrate principles discussed in theory. The result is a text that outlines the treatment fundamentals and shows how to improve the therapeutic outcomes involving orthodontic-periodontic interventions.

Flowable Composite Resins: Esthetics at Your Fingertips

Kratochvil’s Fundamentals of Removable Partial Dentures

Ting-Ling Chang, Daniela Orellana, and John Beumer III

In the 1960s, Professor F. J. Kratochvil recognized the importance of biomechanics in removable partial denture (RPD) design and used these principles to develop a new design philosophy. This “RPI system”—a clasp assembly consisting of a rest, a proximal plate, and an I-bar retainer—changed how clinicians approach partial denture design and is now used throughout the world. This textbook provides an overview of Kratochvil’s design philosophy and the basic principles of biomechanics it is based upon. Topics include components of RPDs and their functions, design sequences for maxillary and mandibular RPDs, and techniques for surveying and determining the most advantageous treatment position. A chapter dedicated to digital design and manufacturing of RPD frameworks highlights new technology in this emerging field. Additional topics include optimizing esthetic outcomes through attachments and rotational path RPDs as well as applying the RPI system to patients with maxillofacial defects. The authors provide illustrations of clinical cases throughout the book as well as an illustrated glossary of prosthodontic terminology. This textbook will prepare students and general practitioners to design and fabricate a biomechanically sound RPD framework for just about any dental configuration they encounter.

Kratochvil’s RPD Design Principles Five Decades Later: How Today’s Prosthodontists Continue to Build Upon His Legacy

Posted on December 20, 2018 by Michelle Hartman

Reading time: 12 minutes

Few technologic advancements in human history remain the same forever. As improvements are made, technology changes and evolves until, in some cases, the present-day technology looks nothing like its predecessor: compare the device you’re reading this on to the Z3 or the Manchester Baby—the differences are quite stark, especially if you’re using a handheld device. But some inventions achieve such a high level of innovation that they leave little room or need for further improvement. Such is the case with Professor F. J. Kratochvil’s RPI system for removable partial denture (RPD) design, which has remained in use worldwide since its introduction in 1963 and continues to influence modern RPD design.

Professor F. J. Kratochvil, conferring with Dr Arun Sharma.

“Few people changed the practice of prosthodontics like Prof Kratochvil did,” explains Ting-Ling Chang, DDS, Section Chair of the Division of Advanced Prosthodontics at the School of Dentistry of the University of California, Los Angeles. “Prof Kratochvil’s most notable contribution to our discipline was the development of the so-called ‘RPI system’ of RPD design: a clasp assembly consisting of a rest, a proximal plate, and an I-bar retainer. He was one of the first to recognize the importance of biomechanics in RPD design and used these principles to develop a whole new design philosophy. His initial article in The Journal of Prosthetic Dentistry in 1963 (and later his textbook) forever changed the way dentists approach partial denture design.”

Fifty-five years later, Dr Chang has authored a new textbook titled Kratochvil’s Fundamentals of Removable Partial Dentures along with two of her colleagues from the UCLA Division of Advanced Prosthodontics: Assistant Clinical Professor Daniela Orellana, DDS, and Distinguished Professor Emeritus John Beumer III, DDS, MS. The book is a testament to the enduring design of Prof Kratochvil’s RPI system, and it demonstrates a rare instance of success in the challenge of developing innovations that go beyond merely improving upon present technology for the short term and instead achieve a level of innovation with lasting relevance in a rapidly changing field like prosthodontics.

The Difference in the Design

“Many of Prof Kratochvil’s original design features have been incorporated into other current RPD designs,” Dr Beumer explains. “For example, almost all modern designs incorporate proximal plates and use the mesial rest concept when restoring edentulous extension defects. Currently, the only major difference currently between popular designs is the type of retainer used. Two other popular retainer types besides the I-bar include the circumferential clasp in association with the RPA system and the wrought wire retainer.”

“The main difference between Prof Kratochvil’s RPI system and other RPDs used today is the biomechanical consideration and the favorable outcomes offered by the RPI design, especially for extension-base RPDs,” Dr Chang adds.

That biomechanical consideration inherent in the design of the RPI system is exactly what made Prof Kratochvil’s work so groundbreaking in the 1960s and what maintains its relevance today. “The reason Prof Kratochvil’s design has remained scientifically sound,” Dr Orellana explains, “is because the biomechanics of teeth and RPDs have not changed. Before him, RPDs were considered a transitional appliance to complete edentulism. Prof Kratochvil was one of the first clinicians to recognize the importance of biomechanical consideration in RPD design because he was thinking about RPDs as a long-term versus transitional treatment. One of the most significant improvements his system provides over others is that the RPI design is a stress-relieving design that allows for rotation of the appliance without exerting detrimental forces to the abutment tooth, which was a complete change from the effects of previous RPD designs on the abutment teeth.”

(a) Placement of the rest adjacent to the edentulous extension area may produce a tipping force during function, which opens the contact between the abutment tooth and the adjacent tooth. (b) Moving the rest away from the edentulous area produces a direction of force that tends to maintain contact with adjacent teeth, resulting in multiple-tooth support and acceptable directions of force application.

Proximal plates are plates of metal in contact with proximal surfaces of the abutment teeth. They should extend 2 mm onto the mucosa of the alveolar ridge (arrows).

Indeed, RPDs have long borne the reputation of being detrimental to the remaining dentition when employed long-term. “This misconception,” Dr Beumer explains, “is largely based on clinical reports published in the 1950s and 1960s before Prof Kratochvil developed his system. During this time, the acrylic resin portion of the RPD frequently came into contact with the surfaces of the abutment teeth, and, after a period of use, the porous acrylic resin would become infiltrated with oral microorganisms, predisposing the abutment teeth to caries and periodontal breakdown. In Prof Kratochvil’s design, the use of a metal proximal plate mitigated this risk because the metal is nonporous. Biomechanics played its role as well, but I think the use of the metal proximal plate was equally impactful in improving outcomes because of the additional feature that its use united and consolidated residual arch segments, permitting a wider and more equitable distribution of occlusal forces. Of course, patient oral compliance continues to be the most important factor in the survivability of any prosthetic option we employ, whether it be fixed, removable, or implant-retained. Patients who have a history of multiple tooth loss are often noncompliant with regard to oral hygiene, and this factor was often not taken into account with early RPD clinical outcome reports.”

Dr Chang expounds on the biomechanical improvements offered by Prof Kratochvil’s design and how that can impact the health of the abutment teeth: “The reason the general perception persists that RPDs will compromise the health of the abutment teeth is because many RPDs delivered today include little to no consideration of the biomechanical aspect during their design. Laboratory surveys show that many RPD designs are done by laboratory technicians who have never seen the patients or the clinical situations. Back in the clinic, many clinicians feel less confident in designing RPDs because more and more dental schools have and continue to reduce the curriculum time devoted to removable prosthodontics. Studies show that a well-designed RPD does not compromise the health of the abutment teeth in patients with good oral hygiene. The two key factors there are: (1) a well-designed RPD and (2) good patient oral hygiene. As clinicians, unfortunately we can only truly control the first factor, and this book is written to promote that goal and help readers provide quality prostheses for their patients so we can change this widespread misperception.”

(a) The circular anteroposterior strap is favored for most maxillary RPDs because it combines maximum rigidity and strength with minimum bulk. The rests on the canines provide indirect retention. (Courtesy of Dr A. Davodi, Beverly Hills, California.) (b) The position of the posterior strap should be anterior to the vibrating line and terminate adjacent to but just short of the hamular notch. As such, the acrylic resin of the denture base can cover the tuberosity and smoothly transition with the RPD framework.

RPDs Versus FPDs Versus Implants

No modern conversation about treatment options for restoring missing teeth would be complete without mentioning implants, and it does seem to correlate that as interest in implants among both clinicians and patients increases, interest in and education devoted to RPDs decreases. Implants are largely discussed and positioned as the ideal solution for missing teeth: a fixed, subgingival replacement system that to the patient looks and behaves like natural teeth.

“Implant technology is very popular among clinicians,” Dr Chang explains, “because of its profitability and high patient interest. But as clinicians we also need to acknowledge the fact that implants are not the best option for everyone. In fact, there are many circumstances where RPDs are the best option for the patient. Just to name two: patients with a large deficiency in hard and soft tissue, making it challenging to achieve optimized esthetics using fixed partial dentures (FPDs) or implants, as well as patients with systemic health factors at play that contraindicate implants or financial limitations that prevent both FPDs and implants. Likewise, it is important to discuss situations where a combination of modalities may be desirable. For example, some patients cannot afford a fixed prosthesis supported by multiple implants. Instead, we can consider placing one or two implants and an RPD for an implant-enhanced RPD solution.”

(a) Pneumatized maxillary sinus. (b) Resorption of bone over the inferior alveolar nerve. Both preclude implant placement in the absence of site enhancement.

“As a clinician,” Dr Orellana emphasizes, “it is important to integrate individual clinical expertise with the best available scientific evidence during the decision-making process for patient care.”

As someone whose clinical experience spans both before and after the introduction of dental implants, Dr Beumer offers a unique perspective: “Osseointegration is the most impactful phenomenon introduced to the dental profession in my career,” he states, “and has been widely promoted to the public by commercial interests. However, as I frequently remind my students, the functional outcomes offered by implant-supported prostheses frequently are no better than the functional outcomes offered by RPDs. I have even emphasized this point in my textbook Fundamentals of Implant Dentistry: Prosthodontic Principles (Quintessence, 2015). Moreover, RPDs frequently provide a superior esthetic outcome when compared with implant options. Given this information and the cost difference, most patients will choose RPDs. However, if they have the financial resources, many patients prefer to be restored with a fixed implant–retained and supported prosthesis.”

(a) Bilateral extension-base RPD. (Courtesy of Dr R. Faulkner, Cincinnati, Ohio.) (b) Bilateral extension areas restored with a single implant connected to a natural tooth abutment. The mastication efficiency of the RPD is equivalent to that obtained with the implant-supported FDP.

So when treatment planning, if a patient is a suitable candidate for an RPD or implant-supported prosthesis and the expected functional outcomes are the same, how do clinicians guide their patients through the treatment options? When one of the major differences affecting patient choice—cost—results in higher profitability for the clinician, how do clinicians present the options fairly and appropriately?

“With regard to patient satisfaction,” Dr Beumer explains, “I present all treatment options to the patient with their pros and cons and let the patient make the choice. I also provide input and give them my opinion as to which option best meets their needs. In my experience, most patients select a an RPD, the main reasons being cost, insufficient bone to receive implants in the desired sites, and the prospect of the multiple surgeries needed for implants. I also emphasize the need to consider conventional treatment options when I present my lectures on implant prosthodontics to students.”

“As a clinician,” Dr Chang states, “I prefer the RPI system as my first choice if there is no other contraindication. RPI RPDs offer superior esthetics and favorable biomechanical outcomes. It is a simple, elegant, and very hygienic design compared with other clasp assemblies. But the consideration of prosthodontic tooth replacement treatment options for partially edentulous patients always starts with listening to the patient first. Each patient has unique expectations and prior experiences; understanding their concerns and their priorities should always be your first step. The prosthodontic process is a patient-centered and shared decision-making process. In many cases, RPD may be the most suitable tooth replacement option due to various patient factors, and it is our duty as responsible prosthodontists to continue to offer this modality.”

(a to f) I-bar retainers provide superior esthetic results with minimal metal display. Only the tips are visible in most patients.

The Future of RPDs

With the rise in implant dentistry, there will be inevitable shifts in removable prosthodontics. One of these shifts has already presented itself in changes to education curricula in dental schools worldwide.

“We see reduced curriculum time devoted to RPDs in many dental schools, both in the classroom and the clinic, in order to free up curriculum time for emerging fields such as implant, esthetic, and digital dentistry in the DDS programs. But RPD treatment will never become obsolete because the need to restore partially edentulous patients will never go away; indeed, the partially and fully edentulous population will only continue to grow. That is why it’s important to offer other resources for clinicians and recent graduates such as reference books like our textbook as well as continuing education in RPDs.”

In addition to the changes in educational program design, advances in digital dentistry are also impacting RPDs and creating new and exciting possibilities.

“I think digital design and CAD/CAM technology is very exciting,” Dr Chang enthuses. “It is a very robust tool in improving efficiency and accuracy for our patient care. As an educator, I see a huge impact on creating fun and visual learning experiences using the digital design software. However, digital design and CAD/CAM will not change the RPD treatment principles or the RPI design concept.”

(a) Digitized master cast. (b and c) Virtually designed RPD framework. (d and e) Cast framework seated on the stone master cast. (f) Completed prosthesis seated intraorally. (Courtesy of Dr J. Jayanetti, Los Angeles, California.)

“I believe the Kratochvil RPI concept represents a near end point of the evolution of RPD design,” Dr Beumer states, “and that this system will represent the standard for the foreseeable future. The most recent innovations have addressed retainer designs, such as the wrought wire clasp (Brudvik) and the RPA system (Eliason), and both have employed proximal plates and the mesial rest concept. Also, the RPI system subsequently developed by Krol adopted all of Prof Kratochvil’s principles but differs only by a slightly shortened proximal plate.

“Prof Kratochvil was a logical, disciplined, and creative thinker who was willing to challenge the accepted dogmas of his day. It is interesting to note that when he first introduced his concepts, he was frequently criticized by the dental establishment. The points of innovation now—CAD/CAM and digital dentistry—will only affect the means of fabrication or adjudicate the treatment planning process. The design concepts promoted by Prof Kratochvil will continue to endure.”

While the peripheral aspects of RPD treatment, including the methods of fabrication, materials, and treatment-planning software, will continue to evolve, one important factor will stay the same—the biomechanics of the human dentition will not change, and therefore any rehabilitative solutions to replace the missing dentition will continue to follow these same rules. And as the partially edentulous patient population grows, RPDs will remain an important treatment option for clinicians dedicated to serving their patients’ best interests, meaning Kratochvil’s Fundamentals of Removable Partial Dentures will be an important addition to the shelves of prosthodontists for years to come.

Early-Age Orthodontic Treatment

Aliakbar Bahreman

This book presents readers with the information necessary to understand the morphogenesis of orthodontic problems, to differentiate among various conditions, and to apply early intervention approaches to optimal effect. Through integration of basic science and clinical practice, detailed case reports, and abundant illustrations, the author provides an overview of dental development, from tooth formation to permanent occlusion; emphasizes the developmental stages that must be recognized during patient examination to facilitate differential diagnosis; presents clear, step-by-step instructions for different treatment options; and demonstrates the benefits achieved by intervention in developing malocclusions and guidance of eruption. The discussions in part 1 of the concept of early-age treatment and the basic foundation of occlusal development empower practitioners to detect anomalies and intervene as necessary. Part 2 consists of chapters explaining the ontogeny, diagnosis, and early detection of, as well as the proper intervention for, nonskeletal problems. Part 3 includes chapters on early intervention for dentoskeletal problems in the sagittal, transverse, and vertical dimensions. This book cuts through the controversy surrounding early versus late treatment and shows that clinicians must decide on a case-by-case basis when to provide orthodontic treatment.

Cephalometry in Orthodontics: 2D and 3D

Edited by Katherine Kula and Ahmed Ghoneima

Cephalometrics has been used for decades to diagnose orthodontic problems and evaluate treatment. However, the shift from 2D to 3D radiography has left some orthodontists unsure about how to use this method effectively. This book defines and depicts all cephalometric landmarks on a skull or spine in both 2D and 3D and then identifies them on radiographs. Each major cephalometric analysis is described in detail, and the linear or angular measures are shown pictorially for better understanding. Because many orthodontists pick specific measures from various cephalometric analyses to formulate their own analysis, these measures are organized relative to the skeletal or dental structure and then compared or contrasted relative to diagnosis, growth, and treatment. Cephalometric norms (eg, age, sex, ethnicity) are also discussed relative to treatment and esthetics. The final chapter shows the application of these measures to clinical cases to teach clinicians and students how to use them effectively. As radiology transitions from 2D to 3D, it is important to evaluate the efficacy and cost-effectiveness of each in diagnosis and treatment, and this book outlines all of the relevant concerns for daily practice.

3D Cephalometry: Is It Right for Your Orthodontic Practice?

The Tongue

Edited by Andreas Filippi and Irène Hitz Lindenmüller

As the largest organ in the oral cavity, the tongue not only plays a primary role in masticatory and speech function—it is also a significant indicator of health, demonstrating signs of both oral pathologies and diseases that can affect the entire body. Because no health care provider gets the opportunity to examine a patient’s tongue as often as the dentist, it is essential for dentists to recognize when there may be a problem with the tongue and what the problem is. In addition to an overview of tongue anatomy and general diagnosis and treatment recommendations, this book contains an atlas of more than 50 specific diseases and health concerns that may present signs and symptoms in the tongue. Each is outlined in a quick-reference table describing etiology, prognosis, and more and is accompanied by photographs of different ways the condition can present. A true diagnostic aid, this guide will allow clinicians to identify and address any abnormality a patient’s tongue may exhibit.

Clinician’s Handbook of Oral and Maxillofacial Surgery, Second Edition

Edited by Daniel M. Laskin and Eric R. Carlson

There are frequent situations in which oral and maxillofacial surgeons find themselves in need of an immediate answer to a clinical problem. However, this can involve a time-consuming search for the appropriate reference source. This book continues the format of the previous edition by providing a single place to quickly find information on a diverse range of clinical topics, including dentoalveolar surgery, maxillofacial trauma, craniofacial anomalies, and oral pathology. All of the previous chapters have been updated, and new chapters on implantology, cleft lip and palate, maxillofacial reconstruction, oral squamous cell carcinoma, and cosmetic surgery have been added. Moreover, increasing the size of the book has allowed for the inclusion of many summary charts, tables, clinical photographs, and radiographs, which was not possible in the previous version. As a result, this new edition provides expanded information in an improved format.

Although this book is designed as a quick reference source, familiarizing oneself with its content in advance will both add to the reader’s general knowledge base and improve the ability to find information quickly in urgent situations. Residents in oral and maxillofacial surgery should find its content particularly useful during their clinical training, and the concise organization of the material should also be helpful to them in retaining information when subsequently preparing for the American Board of Oral and Maxillofacial Surgery.

Short and Ultra-Short Implants

Edited by Douglas Deporter

Research has shown that short implants are not only a viable option but oftentimes a superior one that carries fewer risks for the patient and dentist, especially in resorbed jaw sites. As clinical trials continue to underscore the safety and efficacy of short implants, more dentists are considering their use with real interest, and this book provides the information clinicians need to incorporate short implants into their own practice. The book reviews the clinical effectiveness of short implants and then describes treatment protocols for the various types of short implants and their placement in different areas of the mouth. Case presentations demonstrate the recommended techniques and showcase the results.

Energizing our ingenuity and imagination, this book lays the groundwork for dentistry’s vibrant and exciting future.

Autologous Blood Concentrates

Arun K. Garg

Since the discovery of platelet-rich plasma (PRP) 25 years ago, interest in the use of autologous blood concentrates as adjuncts to surgical treatment has exploded. As more and more medically useful components of autologous blood concentrates have been identified, a host of unique acronyms such as PRF, CGF, PRGF, and more have surfaced, resulting in significant confusion among clinicians as to which material to use and when. Written by one of the original co-discoverers of PRP, this book tackles this issue of “too much information” by illuminating the science behind the clinical use of autologous blood concentrates as adjuncts to surgical treatment and helps to establish a foundation of practical knowledge for clinical use. The first part of the book summarizes the current literature from all aspects of medicine currently using autologous blood concentrates, showing both the possible applications as well as the limitations of these biologic materials. The second part of the book provides step-by-step instructions and richly illustrated treatment protocols for a number of applications for autologous blood concentrates specific to the practice of implantology and oral and maxillofacial surgery. Comprehensively researched and expertly written, this book is a must for clinicians who are just beginning to incorporate autologous blood concentrate treatment into their practice as well as experienced practitioners.

Botulinum Toxin for Facial Harmony

Altamiro Flávio

The mastery of dentistry brings esthetic knowledge of the face that is applicable to more than just the teeth. In the process of performing a complete facial analysis, the practitioner can identify asymmetries and concerns localized to an area—such as the forehead, eyebrows, nose, or lower face—and offer Botox therapy to increase facial harmony. This book outlines the many clinical uses for Botox, with detailed illustrations and case presentations to support each procedure. The first part of the book covers systematic facial analysis, photographic documentation, and how to plan treatment. Special attention is paid to the anatomy and physiology of the face and the identification of injection points. Detailed treatment instructions for dosage, syringe type, and needle size are included for each procedure, as well as guidelines on how to evaluate results anthropometrically to determine whether esthetic treatment goals have been met. This stunning book will change the way you approach facial analysis and widen your esthetic treatment options for patients.

Oral Structure & Biology

Ralf J. Radlanski

Knowledge of the structures of the orofacial region from the macroscopic scale to the molecular level and pathologic changes to those structures enables practitioners to successfully treat patients or seek treatment options. This book presents the structural biologic foundations underpinning dental and oral medicine. Beginning with an overview of the anatomy of the mouth and moving on to the evolution of the oral structures and pre- and postnatal development of the oral cavity, related facial structures, and the teeth, this book describes each part of the orofacial region in terms of its morphology, tissue structure, cellular properties, and development. Functioning as both a textbook for dental students and a reference manual for experienced clinicians, this compendium of the structural biologic foundations of clinical work in dental and oral medicine allows practitioners to integrate current research in molecular biology into a solid framework of knowledge.

Clear Aligner Technique

Sandra Tai

Clear aligners are the future of orthodontics, but digital orthodontics evolves so rapidly that it is hard to keep pace. This book approaches clear aligner treatment from a diagnosis and treatment-planning perspective, discussing time-tested orthodontic principles like biomechanics and anchorage and demonstrating how to apply them to orthodontic cases using these appliances. Each chapter explains how to use clear aligners to treat a given malocclusion and teaches clinicians how to program a suitable treatment plan using available software, how to design the digital tooth movements to match the treatment goals, and finally how execute the treatment clinically and finish the case well. This clinical handbook will prepare orthodontists and dental students to exceed patient expectations with the most esthetic orthodontic appliance currently available.

The Tongue: What Dentists Should Know About Treating It

Posted on November 8, 2018 by Michelle Hartman

Reading time: 8 minutes

The fields of medicine are largely divided based on organs or organ systems. Gastroenterologists treat the digestive system, cardiologists treat the cardiovascular system, pulmonologists treat the respiratory system, etc. Dentistry itself is largely defined by the treatment of teeth, although dentists also treat the entire oral cavity as well as the jaw and face. But which medical professional is responsible for monitoring the general health of the tongue? In their new book The Tongue, Andreas Filippi, Prof Dr med dent, and Irène Hitz Lindenmüller, Dr med dent, are putting forth the argument that dentists are the perfect candidates to treat the tongue and should therefore develop their knowledge base regarding its evaluation and treatment.

“There are a number of medical professionals who have the opportunity to observe a patient’s tongue,” Prof Filippi states. “Specialists and general practitioners alike regularly look into the oral cavity or throat of their patients. The tongue is the largest organ within this field of vision, yet practitioners have relatively little detailed knowledge about it. Dentists in particular see their patients’ tongues regularly during the course of routine dental check-ups, whereas an ear, nose, and throat specialist or general practitioner only gets to see the tongue when examination of the patient requires it.”

Dentistry should not concentrate solely on the teeth.
Andreas Filippi, Prof Dr med dent

By nature, dentists have the most opportunities to observe and identify changes or pathologic signs in a patient’s tongue. However, there is a deficit in dentistry where knowledge of the tongue is concerned.

“In training as well as in continuing professional development,” Prof Filippi states, “relatively little attention has so far been paid to the tongue. This is evident in everyday clinical practice from uncertainties about the visible or sometimes invisible changes to the tongue—for example, burning tongue—that occasionally crop up. However, the tongue not only exhibits a multitude of normal variations and pathologic changes, but it also tends to reflect the general medical, internal, diet-related, and mental state of our patients. It cannot and should not be ignored.”

“Dental practitioners should always examine the tongue,” Dr Hitz Lindenmüller adds, “because the oral mucosa and especially the tongue mirror the health of the body and soul. The tongue can give you important information about pathologic disorders and systemic diseases that, often, even the patients are unaware of. Examining the tongue costs you 1 additional minute of time at maximum, yet it is worth that much and more because you acquire so much information about the patient’s oral and general condition.”

To drive her point home, Dr Hitz Lindenmüller provides the following example from her practice: “One day, a young female patient presented with papules on the gums and on the tongue. Based on those clinical findings as well as an examination of her arms and hands, it was discovered that the clinical findings were pathognomonic for a mucosal neuroma syndrome called Cowden syndrome. This diagnosis was significant because patients with Cowden syndrome are at increased risk of developing cancer; in fact, it was later found that her father, who died of cancer, likely shared the same gene mutation that causes Cowden syndrome.”

(left) Patient with distinct mass in the anterior tongue area. The surface exhibits papillomatous papules. (right) The patient with Cowden syndrome has a cobblestone-like tongue surface.

Prof Filippi offers practical guidance on exactly how dental practitioners should evaluate the health of the tongue. “During a thorough dental examination,” he advises, “the borders, underside, and base of the tongue as well as the floor of the mouth should be inspected as a basic principle. If there are any visible or merely palpable changes, further diagnostic investigation should be discussed and—depending on the results—suitable treatment initiated.”

In addition to its connection to generalized and systemic disorders and diseases, the tongue also plays an important role in many of aspects of routine dental care.

“The dorsal surface of the tongue is the only oral mucosa to have a microrough surface,” Prof Filippi explains. “Hence, the tongue harbors more than half of all oral microorganisms, which live there in a highly organized biofilm that protects them against chemical and mechanical influences. Aerobes are more likely to be found on the surface, and anaerobes can be found in the depth of the tongue. These anaerobes reside in the fissures of the strikingly rugged filiform papillae, which are only present on the dorsal surface of the tongue.

When it comes to caries prevention, clean teeth are only one consideration.
Andreas Filippi, Prof Dr med dent

“Treatment of the consequences of microbiologic diseases in the oral cavity such as caries and periodontitis is the most common type of work done in dental practices. Some causal microorganisms may reside on the teeth or in the periodontal pockets, but a great many reside on the tongue. Even if great skill and effort is put into cleaning individual periodontal areas, this may not actually have a sustained impact on reinfection of the periodontium. Consider the current debate about the benefit of dental floss or the fact that the market introduces new toothbrushes each year that supposedly clean better than past toothbrushes. When it comes to caries prevention, clean teeth are only one consideration. In light of this growth of knowledge in prevention and therapy, modern medicine is fortunately focusing more and more on the largest site of oral microorganisms: the tongue. This is illustrated by examples such as full-mouth disinfection, modern halitosis treatment, and the idea of caries prevention by means of tongue cleaning. Fundamentally, dentistry should not concentrate solely on the teeth. It is not without reason that universities in many countries have departments such as Oral Medicine, Oral Diagnostic Sciences, or Oral Health—a trend that should spread across the globe.”

The health and function of the tongue also have an enormous impact on a patient’s quality of life. The functions of the tongue range from those that are necessary, such as speaking and moving food around in the mouth during mastication, to those that make life infinitely more enjoyable, like tasting. Prof Filippi emphasizes that all functions of the tongue deserve concern from practitioners when they are impaired in a patient.

If one or more of the functions of the tongue is restricted, quality of life can be greatly impaired.
Andreas Filippi, Prof Dr med dent

“The tongue performs many important functions,” Prof Filippi explains, “and if one or more of those functions is restricted, quality of life can be greatly impaired. Many people suffering from advanced dysfunction or even complete loss of individual functions can also suffer from depression as a result. In addition to objective findings, subjective complaints also require careful evaluation. Articulation as well as the senses of touch and taste are so important to quality of life that patients who undergo radiotherapy to the head and neck area repeatedly report complaints. In addition to mucositis, these patients suffer severe impairment of their sense of taste—things taste differently or blander than usual. In some cases, patients develop aversions to particular foods and stop enjoying things they used to like eating. Fortunately, these sensory disturbances usually go away after oncology treatment is finished. Subjective complaints also play a growing role in the aging population, who often require drug treatment in the general medical practice. For example, a decrease in saliva flow rate is a common problem that can lead to redness, inflammation, fungal infections, and a burning sensation of the tongue. This frequently demands an interdisciplinary approach to provide satisfactory help to patients whose quality of life is often impaired.”

In order to address the gap in clinical knowledge regarding the tongue and to aid practitioners in diagnosis and treatment, Prof Filippi and Dr Hitz Lindenmüller developed their book The Tongue as a practical tool for clinicians.

“Today’s dental practitioners do not receive adequate education and training on the tongue,” Dr Hitz Lindenmüller explains. “We wrote this book to function as the missing link—to connect current research to clinical practice.”

“The aim of this book,” Prof Filippi states, “is to shed light on the tongue from the perspective of current academic literature. It is designed as an illustrated atlas and reference work rather than as a textbook in order to best serve clinicians when diagnosing and treating changes in the tongue. A further aim is to communicate the latest knowledge to students of dentistry and medicine for the benefit of their eventual patients.”

By strengthening their basis of knowledge regarding the tongue and its associated health concerns, clinicians will be able to provide better overall care to their patients and act as first responders by catching signs of underlying illnesses when symptoms elsewhere in the body may otherwise go unnoticed by the patient and the clinician. The result is a stronger standard of care that addresses the health of the largest organ in the oral cavity.

Andreas Filippi, Prof Dr med dent, is Professor, Senior Physician, and Deputy Head at the Department of Oral Surgery, Oral Radiology, and Oral Medicine at the University Center for Dentistry of the University of Basel in Switzerland. He founded the Dental Accident Center in 2006 and the Center for Salivary Diagnosis and Drying of the Mouth in 2016. Prof Filippi is active in various professional societies and has published and lectured extensively in the fields of oral medicine and oral surgery.

Irène Hitz Lindenmüller, Dr med dent, is Senior Assistant at the Department of Oral Surgery, Oral Radiology, and Oral Medicine at the University Center for Dentistry of the University of Basel in Switzerland, where she has been in charge of oral mucosa consultations since 2001. Since 2008, she has also practiced as an oral surgery specialist in an orthodontic practice. Dr Hitz Lindenmüller is active in the field of oral medicine and oral surgery as a speaker and author of numerous technical papers.
