Treatment Planning Demystified

Reading time: 11 minutes

Imagine yourself as a beginning dental student. You attend your first restorative dentistry conference where you hear the term treatment planning. Intrigued and eager to learn how to develop a plan of care for your future patients, you pull out your notebook, pen poised over the page. But by the end of the conference, you’re still no clearer on the concept than when you arrived. Disheartened, you return to school. A year later, the subject has only been touched on briefly in your classes, always within the context of a specific discipline. By the time you’re walking down the aisle with your diploma, nothing has changed. You know all the details but are still unsure how to put them all together.

Treatment planning is implied but never formally taught.

According to Antonio H.C. Rodrigues, CD, CAGS, MScD, a basic understanding of treatment planning is a common problem his students face. In fact, it’s something even experienced dentists struggle with. He defines treatment planning as “giving a solution to a previously identified problem.” The Glossary of Prosthodontic Terms further defines the concept as “a sequence of procedures planned for the treatment of a patient after diagnosis.” In other words, the problem (ie, diagnosis) dictates the solution (ie, treatment).

Successful treatment planning requires intimate knowledge and understanding of the problem, the solution, and any treatment modifiers, which is part of the philosophy of comprehensive care that Dr Rodrigues practices. While treatment planning is a vital part of overall treatment and crucial for long-term success, the process of how to effectively plan a treatment often remains vague and confusing due to the lack of available education. Dental schools are bereft of courses exclusively dedicated to the subject, yet it is too basic a topic to be covered at most scientific conferences. Treatment planning is implied but never formally taught. This oversight in education, coupled with tomes of literature too specialized to be helpful, leaves inexperienced practitioners floundering and overwhelmed.

“While much has been written on treatment planning, most authors tend to concentrate their thoughts within their own specialty,” Dr Rodrigues explains. “Consequently, only a segmented view of the patient’s condition is presented, which may compromise treatment results in the long term.”

The book encompasses treatment planning beyond the specialty, which stresses the importance of cultivating relationships with other specialties to make the best recommendations to meet patients’ needs.

Because there are no set guidelines in planning procedures, students find themselves grappling with endless questions on how to sift through the information to determine what’s important, how to decide what to do first, and how to pull it all together. After observing his students resort to the fickle insights of intuition, Dr Rodrigues developed a comprehensive resource called Treatment Planning in Restorative Dentistry and Implant Prosthodontics. The first of its kind, his book provides a way to systematize the process so it’s not left to a scattershot approach. The need for this philosophy of total care is high due to the current emphasis on predictability, reliability, and successful long-term results.

“My book provides a comprehensive approach to treatment planning, outlining a clear, objective, and simple thinking process that can be easily applied in daily practice,” Dr Rodrigues says. “It essentially provides the reader with a roadmap to be used as a reference from the very initial procedures until the final restorative treatment, always considering the patient in his or her entirety.”

In the past, discussions between different areas of expertise were discouraged in favor of quick solutions, but it’s crucial for clinicians to think beyond their own skillset to maximize treatment success. The book encompasses treatment planning beyond the specialty, which stresses the importance of cultivating relationships with other specialties to make the best recommendations to meet patients’ needs.

History of Treatment Planning

The early days of treatment planning called for brief, quick-hit discussion and immediate recommendation to arrive at a simple solution. This decision was often shrouded in uncertainty and based on the dentist’s empirical experience, without any scientific evidence behind it. The diagnosis was not clearly articulated, especially not to the patient. Furthermore, the patient was not provided with treatment options and usually left treatment decisions up to the dentist’s personal judgment.

“Most complications and failures, particularly in restorative dentistry, are directly or indirectly related to inadequate planning.”

The intent was to solve a specific problem in a specific area, often based heavily on patient request. This led to cases of treatments tailored to patient expectations without further analysis to investigate other potential problems. The result of such segmented care was an inefficient, often detrimental treatment that caused more problems for the patient in the long run.

“Most complications and failures, particularly in restorative dentistry, are directly or indirectly related to inadequate planning,” Dr Rodrigues stresses. “When planning procedures are not carried out accordingly, dentists tend to provide either overtreatment or undertreatment for their patients. Either situation may cause problems in the long term. Therefore a book offering guidelines to help the dentist with the development of predictable planning procedures is of utmost importance.”

“Comprehensive planning is the planning approach that considers the patient as a whole as opposed to the individual specialty planning which focuses mainly on a specific area or problem.”

With Treatment Planning in Restorative Dentistry and Implant Prosthodontics, the previous norm of a short discussion of limited treatment possibilities has been replaced with an open format of informed, in-depth conversations about every realistic solution within the range of available treatment options. Gone are the days of specific problem solving without consideration for the larger context, which led to significant problems being overlooked. Dr Rodrigues urges clinicians to focus on comprehensive patient care to achieve long-term success. In other words, they should make sure the treatment plan is complete before considering specialty options.

“Comprehensive planning is the planning approach that considers the patient as a whole as opposed to the individual specialty planning which focuses mainly on a specific area or problem,” Dr Rodrigues says. “Both planning modalities are of paramount importance for achieving successful results. However, before treating a specific area or problem, the dentist should first become familiar with the patient in his or her entirety.”

Philosophy of Comprehensive Care

Phases of the treatment planning protocol and their requisite procedures: (1) gathering and organization of clinical data and development of the problem list; (2) interpretation of the gathered data and determination of the diagnosis, prognosis, and treatment objectives; (3) analysis of the treatment options and development of the treatment plan; and (4) patient education, treatment plan presentation, and informed consent.

The philosophy Dr Rodrigues practices and advocates for consists of three parts:

  1. A comprehensive approach to treatment planning
  2. Restorative planning principles
  3. The planning process

Executing a comprehensive approach involves keeping all the patient’s dental needs in mind while assessing the vast amount of data necessary to make a plan. Thorough clinical extraoral and intraoral examinations are key for collecting this data. Treatment Planning in Restorative Dentistry and Implant Prosthodontics provides numerous forms to ease data entry and analysis, including examination checklists and questionnaires, problem lists, and treatment plan outlines. The extraoral examination encompasses the head and neck while the intraoral examination covers the entire oral cavity using diagnostic aids, including radiographs; diagnostic casts, wax-ups, and indices; radiographic templates; and clinical photography.

Standardization is important to promote efficiency and facilitate training, so Dr Rodrigues advises that clinicians perform examinations using the same sequence every time. While they may initially adapt the sequence to their unique practice, he recommends the following sequence for the extraoral examination: (1) face as a whole (ie, facial and dentofacial analysis) and (2) mouth (ie, smile analysis). He also recommends the following intraoral examination sequence: (1) oral mucosa, (2) periodontium, (3) teeth, (4) occlusion and TMJs, (5) edentulous areas, (6) possible orthodontic needs, and (7) possible major oral surgery needs. Teeth should first be evaluated individually, then as a group. The recommended individual tooth sequence is as follows: (1) crown, (2) pulp chamber, (3) root canal, (4) lamina dura, and (5) periodontal ligament space from occlusal surface to apex. Intraoral examinations require an assistant to serve as secretary for data input.

Following data collection, there are three principles of restorative planning to consider: (1) making a diagnosis based on the patient’s current state of health, (2) envisioning the patient’s healthy state, and (3) comparing the two. The first principle involves the clinician’s ability to evaluate the patient’s current state and diagnose the problem accordingly. The second principle is to envision the patient’s healthy state and distinguish between acquired problems and congenital problems. The third principle involves comparing the first two principles to develop a plan to return to the normal healthy state.

Elements involved in the planning process.

The final part of the philosophy involves asking what, how, and who. First, clinicians must develop a firm grasp of what treatment planning is. Then they must understand how to treatment plan. This means outlining the objectives that planning procedures should achieve. In the past, treatment planning existed simply to arrive at a plan of action for generating a general treatment outline and formal payment agreement. Today’s treatment plans go one step further by serving as a valuable patient education tool and reliable means of obtaining informed consent.

The dentist’s role has shifted from final authority to expert advisor, and a major goal of ethical contemporary dentistry involves adequately preparing patients to make sound health care decisions in their best interest. This translates to fully informing patients about their individual conditions and outlining all methods available for treatment. Evidence-based decision-making is an essential part of the process, so it is important for clinicians to supplement the discussion with evidence from dental literature and results from their own practices. Clinicians should identify all existing problems or factors that may lead to problems and weigh the benefits and prognosis of each option. The goal of the treatment plan presentation is to relay all findings, including any scientific information necessary for the patient to make an assessment. With that goal in mind, the core objectives of contemporary treatment planning involve developing a total treatment plan, promoting patient education, and obtaining informed consent.

Sample comprehensive treatment plan.

Finally, clinicians must understand who is best positioned to oversee the treatment from beginning to end. There is often disagreement on which specialty to manage the planning process, but Dr Rodrigues believes this role is ideal for the clinician who delivers the restorative therapy. By developing a solid treatment plan, this person is responsible for preparing the patient to make the best treatment choice. Therefore, it is the duty of the treatment planner to maintain clear, organized notes and to make consultations and necessary referrals to other specialists as needed.

Diagram showing all areas involved in the development of a comprehensive plan of treatment.

“A philosophy providing a thought process to be used in all situations, combined with a consistent and methodical approach, would definitely increase both reliability and predictability in long-term results of the dental treatment as a whole.”

“In view of contemporary dentistry, making a diagnosis and planning a treatment implies the professional responsibility to omit nothing of consequence for the patient,” Dr Rodrigues says. “Deviation from this line of thought has become unacceptable and is no longer tolerated. Therefore, there is a distinct need to teach dental students and all professionals involved with restorative procedures to fulfill their responsibility in the management of a comprehensive treatment plan for the patient, and there has long been a need for an efficient method to successfully address this issue. A philosophy providing a thought process to be used in all situations, combined with a consistent and methodical approach, would definitely increase both reliability and predictability in long-term results of the dental treatment as a whole.”

Treatment Planning in Restorative Dentistry and Implant Prosthodontics
Antonio H.C. Rodrigues

Treatment planning is commonly considered one of the most important phases of any dental treatment and vital for achieving successful long-term results. However, most dental schools do not offer courses exclusively designed for comprehensive planning, and comprehensive planning is rarely discussed at scientific meetings because it is considered a basic topic that practitioners should already understand. This knowledge gap leaves practicing clinicians with few options beyond using their own intuition to solve problems, which is highly unpredictable. Therefore, this book presents clinical guidelines for planning treatments in restorative dentistry and outlines a clear, objective, and simple thinking process that can be easily applied in daily practice, essentially providing the reader with a roadmap to be used as a reference from the very initial procedures until final restorative treatment. Part 1 describes how to identify existing problems by gathering, organizing, and analyzing information obtained during clinical examination. Examination checklists and forms are included to ensure that no important information is left out during the evaluation process. Part 2 focuses on providing solutions to identified problems via restorative treatment options, highlighting the use of implant-supported restorations in the treatment of both partially and completely edentulous arches. Part 3 details how to present treatment options to the patient and includes aspects related to patient education, treatment plan presentation, and obtaining informed consent from the patient. Altogether, this book will transform the way you treatment plan your cases.

Are Strong Occlusal Forces Detrimental to Osseointegration?

Technical or mechanical implant-related complications such as fracture of veneering material or abutment screw loosening have a significant force-related etiology. Bone is capable of a long-term adaptive response over a broad range of loading values, but significant forces can cause a pathologic response (Stanford and Brand, 1999).1 This leads to a natural question: Are biologic implant-related complications, such as implant failure or bone loss, also force-mediated? If strong forces are detrimental to osseointegration, research would be expected to demonstrate that bruxers have higher rates of biologic implant complications in comparison to patients who are not bruxers and that patients with force magnifiers such as cantilevers and high crown-to-implant ratios have higher rates of biologic implant complications in comparison to patients without such force magnifiers. Similarly, if strong forces are detrimental to osseointegration, research would be expected to support the concept of “implant-protected occlusion,” which typically consists of recommendations for eliminating cantilevers, narrowing occlusal tables, and decreasing cusp steepness of implant-supported restorations.

Bruxism is a “repetitive jaw muscle activity characterized by clenching or grinding of the teeth and/or by bracing or thrusting of the mandible” (Lobbezoo et al, 2013).2 Etiology of bruxism is multifactorial and consists of a combination of psychologic factors (eg, stress and anxiety), physiologic factors (eg, genetics), and exogenous factors (eg, alcohol and psychotropic medications). Bruxism can be associated with wakefulness or with sleep and is found in up to 30% of the population (Manfredini et al, 2013).3 A formal diagnosis of nighttime parafunction can be made through polysomnography; however, it is impractical for daily clinical use. In clinical practice and in many clinical studies, diagnosis of bruxism is made based on patients’ self-reporting, which may not reflect true presence. Bruxism has been demonstrated to have a negative impact on prosthodontic technical complications, including implant fracture. By contrast, bruxism has not been found to be associated with periodontal tissue destruction (Manfredini et al, 2015).4

The findings of systematic reviews are largely consistent on the topic of association of bruxism and implant biologic complications. Systematic reviews focusing on animal data found no association between overload and peri-implant bone loss in the absence of inflammation (Naert et al, 2012; Chambrone et al, 2010).5,6 Systematic reviews focusing on human data concluded that bruxism is unlikely to be a risk factor for biologic problems around implants (Manfredini et al, 2014; Chrcanovic et al, 2015).7,8 All systematic reviews highlighted the low quality of the underlying clinical studies focusing on this topic, including reliance on self-reporting to diagnose bruxism, inconsistent definitions of implant failure, and poor control for all confounding variables.

A similar conclusion regarding a lack of significant impact of forces on biologic implant outcomes was reached by studies examining high crown-to-implant ratios (Garaicoa-Pazmiño et al, 2014; Ravidà et al, 2019),9,10 poor prosthesis fit (Katsoulis et al, 2017; Slauch et al, 2019),11,12 and the presence of cantilevers.13–15 A review looking at evidence for the use of occlusal splints in bruxers after implant therapy was unable to identify a single clinical trial addressing this topic (Mesko et al, 2014).16 A systematic review on splinting of adjacent implants provided contradictory evidence (de Souza Batista et al, 2019)17; it appears that splinting has no impact on bone levels but is beneficial in increasing implant survival.

Two recent studies (Chrcanovic et al, 2016; Chrcanovic et al, 2017)18,19 came to a different conclusion with respect to the association of bruxism and biologic implant complications. Chrcanovic et al (2016)18 undertook multilevel mixed effects parametric survival analysis to test the association between bruxism and risk of implant failure while adjusting for potential confounders in a group of 2,670 patients who received 10,096 implants. In an important improvement from previous research efforts, formal criteria were used to define and diagnose bruxism. This retrospective study found that implant failure rates were 13.0% for bruxers and 4.6% for nonbruxers (P < .001). The authors’ statistical model showed that bruxism was a statistically significant risk factor for implant failure (HR: 3.4; 95% CI: 1.3 to 8.8; P = .012). Chrcanovic et al (2017)19 used the same population to conduct a case-control matching study to match the bruxers with a group of nonbruxers. Ninety-eight of 2,670 patients were identified as bruxers. The odds ratio of implant failure in bruxers in relation to nonbruxers was found to be 2.7 (95% CI: 1.3 to 5.9).

Little is known about private practice clinicians’ opinions regarding the influence of bruxism and implant treatment outcomes. A recent study (Thymi et al, 2018)20 conducted semi-structured interviews with dentists who were practicing in nonacademic clinical settings and who had significant experience in implant therapy. The authors observed that provision of implant treatments in bruxing patients was generally a well-accepted practice. Complications were often expected, with most being of minor impact. Contradicting attitudes emerged on the topic of bruxism being an etiologic factor for peri-implant bone loss and loss of osseointegration.

Overall, the topic of forces and biologic implant complications is a complex one with incomplete agreement. On balance, existing evidence points to the implant-bone interface being robust and likely stronger than currently appreciated. This is indirectly evidenced by a gradual shift toward the use of smaller implants and prostheses with larger pontic-to-abutment ratios. Little evidence exists to support the concept of “implant-protected occlusion.”

One Surgery, One Time: Revolutionizing Single-Tooth Implant Therapy

Reading time: 9 minutes

Implant dentistry has evolved significantly since Per-Ingvar Brånemark first introduced the idea of osseointegration to North America in the 1980s. This paradigm shift in treatment purpose has led to a transition from primarily integration and survival goals to prioritizing biologic and esthetic goals.

Enter Dennis P. Tarnow, DDS, and Stephen J. Chu, DMD, MSD, CDT, who have worked for three decades as clinicians, instructors, and researchers in domestic and international continuing dental education. The relationship of this world-renowned surgeon and world-renowned prosthodontist duo working hand-in-hand has been an asset to their practice.

“It is difficult to be an expert in both surgery and prosthetics since there is so much to learn and know,” Dr Chu explains. “The best part of working in the same environment is that we can treat the patient without that individual having to run to different offices to accomplish the same goal.”

“When both clinicians are together, the treatment transition from surgery to prosthodontics is seamless.”

Stephen J. Chu

Their close collaboration of 15 years has also resulted in a sense of appreciation for each specialist’s abilities, directly translating to better patient care. 

“The communication and understanding of what must be done for the patient is crystal clear,” Dr Chu says. “Oftentimes when clinicians are physically in separate offices, communication in treatment can be muted. When both clinicians are together, the treatment transition from surgery to prosthodontics is seamless.”

The most recent collaboration of Drs Tarnow and Chu resulted in The Single-Tooth Implant: A Minimally Invasive Approach for Anterior and Posterior Extraction Sockets. Written by clinicians for clinicians, this textbook capitalizes on the idea of “one surgery, one time” and progresses from simple to complex single-tooth implant scenarios.

Immediate Tooth Replacement Therapy

Replacement of a single tooth with a dental implant is one of the most common situations clinicians encounter on a daily basis. In fact, it makes up about half of daily implant cases, many of which occur in the esthetic zone.

Immediate tooth replacement therapy yields survival rates equal to, if not higher than, delayed implant placement. Delayed placement allows for soft tissue maturation and site development prior to placement, but this advantage occurs at the expense of increased treatment time.

On the other hand, immediate placement allows for decreased treatment time, fewer appointments, and higher patient comfort. Most importantly, it makes preservation of the natural architecture of surrounding hard and soft tissues possible at the time of tooth removal, which is a distinct advantage in today’s esthetics-focused culture. This is in line with the ultimate goal of therapy: to preserve, maintain, and protect existing tissues, rather than introducing the opportunity for esthetic error by attempting to recreate lost tissue.

This predictable restorative and esthetic outcome is possible with proper 3D implant placement, platform switching, and soft tissue support with a provisional restoration. However, immediate replacement has its own challenges, the most common being a collapse of the facial ridge with midfacial recession, resulting in integration success but esthetic failure due to loss of the labial bone plate. While immediate tooth replacement therapy is an excellent choice for many cases, it is not ideal for every situation because not all extraction sockets are alike.

Inverted Implant Technique

It is well known that the labial bone plate and soft tissues in the anterior maxilla are at risk of esthetic dilemmas due to their extremely thin diameter (1 mm or less). Preventing greater than 1 mm of tissue collapse—the threshold for esthetic success—is ideal. While wide implants are most effective at achieving stability, narrow implants should still be considered. Altering the implant length is another possibility, but diameter is more effective at achieving stability than length. However, the wider-diameter, tapered implant design is a poor choice.

It is possible to mitigate the width/length dilemma and achieve the “best of both worlds” with a new, unique “body-shift” concept, or “inverted” body implant design.

Even with the modern switch from an implant survival to an esthetic results mindset, it is possible to mitigate the width/length dilemma and achieve the “best of both worlds” with a new, unique “body-shift” concept, or “inverted” body implant design. This innovative, macro hybrid design combines a tapered apical portion with a cylindrical coronal portion, all in a single body.

“The inverted body-shift concept uses the strategy of changing the diameter and shape of the implant in a singular design,” Dr Chu says. “It’s a happy medium: the primary stability of a larger-diameter implant (apically) and the size of a smaller implant where the bone is thinnest (coronally). More graft material can be placed in this coronal chamber, which increases the thickness around the implant. Also, by reducing the top, the distance between the tooth and the implant is increased to preserve the papilla.”

(a and b) The inverta implant design combines a tapered apical portion with a cylindrical coronal portion, all in a singular body. (c and d) Greater space is inherently generated that allows more graft material to be placed, not only labially but also interdentally into the gap, to create a net increased bone dimension.

Ice Cream Cone Technique

The Single-Tooth Implant: A Minimally Invasive Approach for Anterior and Posterior Extraction Sockets walks the reader through three types of extraction sockets. Type 2 occurs when soft tissues remain intact but the labial bone plate possesses a dentoalveolar dehiscence defect, which increases the risk of midfacial recession.

Fortunately, a solution has been developed: a socket repair procedure called the ice cream cone technique, which allows for reconstruction of the buccal plate dehiscence to enable implant placement.

This technique derives its name from the shape of the absorbable cross-linked collagen membrane, which is contoured into a modified V-shape, or ice cream cone shape. This membrane is placed into the socket cone-side first, and the ice cream side is trimmed to cover the socket opening after graft placement. The membrane lines the socket’s buccal tissues while the socket is filled with bone graft material that is compressed into the socket. The pressure of the graft against the buccal tissue holds the membrane in place. Finally, the membrane is sutured to the palatal tissue, covering the socket.

(a) Type 2 socket with intact soft tissue but a midfacial osseous dehiscence defect. (b) Atraumatic tooth extraction without flap elevation. (c) Socket after tooth extraction and debridement. (d) Collagen membrane contoured into a modified V or ice cream cone shape. (e) Placement of the ice cream cone collagen membrane. (f) Socket filled with graft material. (g) The membrane is extended over the socket and sutured. (h and i) Socket after absorption of the collagen membrane and graft incorporation.

“The ice cream cone technique is a simplified way to combine socket preservation of an extraction socket while being able to build back the missing buccal plate of bone at the same time,” Dr Tarnow explains. “This is all done with a minimally invasive procedure that requires no flap. The membrane, which must be made of a collagen that maintains its rigidity after getting wet, is the key to success. The part that is placed into the socket (the cone part) prevents the soft tissue on the buccal side of the socket from migrating into the graft material before the bone does so. It is guided bone regeneration.”

“The ice cream cone technique is a simplified way to combine socket preservation of an extraction socket while being able to build back the missing buccal plate of bone at the same time.”

Dennis P. Tarnow

The authors recommend using a graft material that is a small-particle, mineralized cancellous freeze-dried bone allograft because it compresses well, maintains shape, and resorbs slowly.

“The ice cream part placed over the top of the socket will only last for a couple of weeks,” Dr Tarnow says, “but it is enough time to contain the graft particles and protect the clot during the first phase of healing.”

The Single-Tooth Implant: A Minimally Invasive Approach for Anterior and Posterior Extraction Sockets covers both the inverted implant and ice cream cone techniques in depth, and more.

“This is my fourth time working with Quintessence,” Dr Chu recalls. “It’s about conveying concepts to the next generation, which is our legacy. The book is outlined and constructed in such a way as to teach concepts from more simple to complex case types for single-implant therapy with minimally invasive techniques for both anterior and posterior sites.”

The Single-Tooth Implant: A Minimally Invasive Approach for Anterior and Posterior Extraction Sockets
Dennis P. Tarnow and Stephen J. Chu

The replacement of the single tooth with a dental implant is one of the most common clinical situations practitioners face on a daily basis. While in the past sockets were left untouched for months after tooth extraction before attending to the residual ridge, today it is possible to perform “one surgery, one time,” which is a huge benefit to both the patient and clinician alike. Written by two world-class masters, this book begins with a discussion of the history and rationale for anterior and posterior single-tooth implants, and then it walks the reader through the three types of sockets—type 1, type 2, and type 3—and their various indications and limitations. An entire chapter is devoted to clinical management of posterior teeth, followed by a chapter on cementation and impression-making techniques and complications. The final chapter is a clinical case appendix detailing 11 cases of single-tooth replacement in all types of sockets previously described. The protocols showcased in this book will make patient care faster, easier, simpler, more predictable, and, in many cases, less costly.
