The relative occlusal force and real-time occlusal contact timing data provided by the T-Scan technology can be used to manage the insertion occlusal force design of implant prostheses, as their long-term survivability is tied directly to their installed occlusal function. This chapter discusses how in daily dental practice, clinicians spend a great deal of time making corrective occlusal adjustments using solely articulating paper as their intended guide. However, current research shows that articulating paper markings do not measure occlusal force, and that dentists poorly Subjectively Interpret the appearance characteristics of the markings, such that implant occlusal force control is highly compromised, leading to peri-implant tissue loss, de-osseointegration, and elevated frequency rates of breakage of implant restorative components. However, by using the T-Scan technology, the clinician eliminates the subjectivity involved in using articulating paper. This ensures the occlusal design of newly-installed implant prostheses are optimal, ensuring prosthesis longevity. Case examples are presented of how occlusal adjustments that employ T-Scan force and timing data with simultaneously-recorded EMG data aid in implant restoration occlusal force control by not only lessening masticatory muscle hyperactivity, but also by improving the muscle tone and length of the face, head, and neck musculature.

The role of occlusion in the progression of periodontal disease remains a controversial subject. Occlusal force, which is a mechanical stress applied to tissues, has always been considered to not initiate, nor accelerate, periodontal attachment loss resultant from inflammatory periodontal disease. This chapter outlines this controversy in great detail, from the perspective that the absence of a validated occlusal force and timing measuring device that can quantify the occlusion, has contributed to the confusion and questions that exist in the scientific community about the relationship between both periodontal disease and peri-implantitis, and the occlusion. The development of a new occlusal measurement technology that records and analyzes precise and reproducible relative occlusal contact force levels in real-time, independent of a clinician's subjectivity, is helping to change the scientific opinion regarding occlusion's role in periodontal and peri-implant supporting tissue loss. The T-Scan 10 system is particularly adapted for treating patients who demonstrate tissue loss combined with occlusal issues. Indeed, after having controlled the major etiologic and risk factors of periodontal disease and peri-implantitis, adjusting the occlusion after active tissue and implant therapy favors healing. The outcome of periodontal treatment aimed at compromised teeth and dental implants, combined with occlusal force excess control from computer-guided targeted occlusal adjustments, is highly predictable, and is characterized by less inflammation, a decrease of probing depths, and the stabilization of bone levels around teeth and dental implants.

The traditional occlusal indicators used in dental practice are articulation papers, Shim-stock foils, elastomeric impression materials, and occlusal wax strips. These static dental materials have been widely believed to have occlusal force descriptive capability. However, modern material studies are challenging the widespread belief that occlusal indicator materials can measure differing occlusal force levels. This chapter evaluates the force reporting limitations of these static occlusal indicators, and discusses how clinicians subjectively interpret their appearance characteristics to determine differing occlusal force levels. This chapter then compares these non-digital occlusal indicators to the T-Scan computerized occlusal analysis technology, that records and displays precise, quantifiable, relative occlusal force variances, and occlusal contact timing sequences. This digital data aids the clinician in making a more accurate occlusal analysis, and can guide the clinician in the correction of occlusal contact force and timing abnormalities, thereby eliminating the subjectivity that is inherent with traditional occlusal indicator use. This chapter further details the diagnostic occlusal capabilities of the T-Scan's digital force and timing data, by presenting two separate studies that compared measured closure and excursive occlusal contact force and timing parameters in orthodontic and non-orthodontic young adults. A commentary is included regarding the clinical pitfalls of using maximally invasive, subjective interpretation to choose occlusal contacts for treatment instead of employing minimally invasive, computer-guided occlusal contact selection. This last section clearly illustrates to the reader that both patients and dentists will markedly benefit from the implementation of occlusal measurement technology.

The Face

In facial contouring surgery, surgeons operate the facial bone to correct bone morphology and thus achieve esthetic feminine face. To evaluate the face appearance after surgery and rehearse every surgical procedure in facial contouring surgery, simulations for tissue peeling, incising and suturing on the face together with bone burring and grafting on the facial bone are required. This paper presents a method that transforms respective tissue vertices to simulate tissue peeling. The transformation is based on specified incisions and clamps as in real facial contouring surgery. This paper also uses an auxiliary structure to represent and record tissue boundary changes inside the face. The elastic, partially plastic and plastic tissue deformation and wound formation during an incision can be simulated by manipulating these boundary changes. The incised wound recorded in the auxiliary structure is also manipulated to simulate tissue generation in wound healing during a suture. This volume manipulation method is combined with the reported method for bone burring and grafting simulations so that high-quality 3D images for illustrating surgical procedures both on the face and facial bone can be achieved. Simulations of two case examples including tissue peeling, incising and suturing procedures, and three modalities of facial contouring surgery demonstrate the effectiveness of the proposed method and system.

This chapter introduces the Air Indexing method for detecting and quantifying cervical dentin hypersensitivity as a companion to the T-Scan Occlusal Analysis System, which evaluates occlusal force and timing values of contacting teeth. The chapter discusses detection, diagnosis, and treatment of clinical signs and/or symptoms of Cervical Dentin Hypersensitivity (CDH). A 17-year-long retrospective study conducted between 1979 and 1996 is presented that illustrates the correlation between Cervical Dentin Hypersensitivity and its resolution following occlusal adjustment. Resulting stress from occlusal contact force is etiologic for non-carious cervical lesion formation and root degradation. This chapter details how biocorrosion and lost protective glycoproteins hasten the effects of applied force, creating CDH symptoms and cervical abfractions. Lastly, the Air Indexing method of CDH diagnosis is melded with T-Scan occlusal analysis to diagnose and treat CDH symptoms. Together, these two methods yield more CDH/occlusal insight than either method can alone.

Common Clinical Finding

This chapter introduces the air indexing method for detecting and quantifying cervical dentin hypersensitivity (CDH) as a companion to the T-Scan Occlusal Analysis System which evaluates force and timing values for occlusal contacts of teeth. This chapter will also highlight an evidence-based retrospective investigation undertaken between 1979 and 1996 that evaluated associations and/or correlations between diagnosed CDH and its resolution following occlusal adjustment. This retrospective's method described the detection, diagnosis, and treatment of the signs and/or symptoms of the common clinical finding amongst patients with CDH. Stress physics will illustrate how small occlusal contacts magnify the impact that applied occlusal contact force has on the cervical regions of teeth. This resultant cervical stress is etiologic for how non-carious cervical lesions (NCCLs) form and degrade tooth roots. This chapter also explains how biocorrosion from endogenous and exogenous sources produces loss of dentin's protective proteins, glycoproteins, and cementum, which add to the effects of applied occlusal force, thereby creating CDH symptoms and NCCLs. CDH appears resultant from the co-factors of occlusal forces that produce cervical stress, along with biocorrosion, that are both modified by occlusal surface friction. The air indexing method of CDH diagnosis is an objective diagnostic means to detect and quantify CDH symptoms during the formation of cervical lesions. This chapter presents the clinical benefits of melding the T-Scan Occlusal Analysis System with the Air Indexing Method when clinically assessing and treating cervical hard tissue pathologies. The clinician gains significantly more occlusal insight as opposed to using either methodology alone, when air indexing is combined with T-Scan's occlusal contact force and timing data. Lastly, this chapter introduces two case reports of how T-Scan guided occlusal adjustments can be effective at reducing CDH and prohibiting the progression of gingival recession.

This chapter addresses the ongoing controversy regarding occlusion's role in the progression of periodontal disease. Occlusal force has been considered a non-factor in the initiation of periodontal attachment loss. However, the absence of a validated measuring device or quantifying method for analyzing the occlusion has contributed to the confusion that still exists in the scientific community today about the relationship between periodontal disease and occlusion. The development of the T-Scan occlusal measurement technology, which is independent of a clinician's occlusal contact force level subjective assessment, may change the scientific opinion about occlusion's role in periodontal disease. This chapter illustrates how the T-Scan 8 system aids in treating patients who have tissue loss and occlusal issues. Notably, after the major etiologic risk factors of periodontal disease have been controlled, adjusting the occlusion with the T-Scan improves healing outcomes resulting in less inflammation, decreased probing depths, and bone level stability.
