This chapter discusses chronic occluso-muscle disorder, which is a myogenous subset of temporomandibular disorder (TMD) symptoms resultant from occlusally activated muscle hyperactivity. It also describes the computer-guided occluso-muscle disorder treatment known as disclusion time reduction (DTR), that studies repeatedly show reduces many common muscular temporomandibular disorder symptoms. T-Scan-based research since 1991 has determined that a significant etiologic component of occluso-muscle disorder is prolonged (in time) occlusal surface friction shared between opposing posterior teeth during mandibular excursions, that occurs in both normal chewing function and during parafunction. This friction results in prolonged compressions of the periodontal ligament (PDL) fibers of the involved teeth, which when in excursive opposing occlusal contact, also experience pulpal flexure that leads to pulpal neural activation, which together with the periodontal ligament compressions, trigger excess muscle contractions within the masticatory muscles. It is this unique neuroanatomy that incites and perpetuates many chronic muscular TMD symptomatology, that can be readily resolved in patients that meet the diagnostic criteria for DTR candidacy, using the ICAGD coronoplasty that is performed in the maximum intercuspal position (MIP), without employing treatment splints, deprogrammers, appliances, orthotics, or mandibular repositioning. Additionally, this chapter will highlight the newest disclusion time reduction therapy (DTR) studies that support the clinical implementation of this highly effective measured occlusal treatment for occluso-muscle disorder.

This chapter discusses chronic Occluso-Muscle Disorder, which is a myogenous subset of Temporomandibular Disorder symptoms resultant from occlusally activated muscle hyperactivity. Published T-Scan-based research since 1991 has determined that a significant etiologic component of Occluso-Muscle Disorder is prolonged (in time) occlusal surface friction that occurs between opposing posterior teeth during mandibular excursions. This friction results in prolonged compressions of the Periodontal Ligament fibers of the involved teeth, which triggers excess muscle contractions within the masticatory muscles. This chapter describes the neuroanatomy of how the excursive friction induces masticatory muscle hyperactivity and illustrates the patient occlusal factors that promote prolonged occlusal surface friction. It explains the patient section criteria for determining if an Occluso-Muscle Disorder patient is a candidate for occlusal intervention, details the computer-guided Occluso-Muscle Disorder treatment known as Disclusion Time Reduction, and supports this measured occlusal treatment with the research studies that validate using this highly effective Occluso-Muscle Disorder therapy.

ABSTRACT Aims and objectives The objective of the study is to assess the outcome of lengthy root canal sessions (more than 2 hours) on temporomandibular joint (TMJ) and its associated structures. Materials and methods Totally, 250 patients who had undergone root canal treatment that lasted for more than 2 hours were examined for the status of TMJ and masticatory muscles. The second part of the examination was performed after 1 week to check for any pain and tenderness. Data were analyzed using Statistical Package for the Social Sciences (SPSS). Results Results showed that patients of older age suffered from more pain postoperatively. Similarly, women experienced more pain than males. Those patients who were treated for their posterior teeth complained of more pain than those treated for anterior teeth. Conclusion Prolonged root canal sessions result in longer and wider opening of mouth for longer period of time, thus causing harm to TMJ and associated masticatory structures and may give rise to sign and symptoms of temporomandibular disorder (TMD). Clinical significance It is prudent to break treatment sessions into shorter appointments and let patients relax during the treatment to prevent any extra stress on the TMJ and associated masticatory apparatus.

BACKGROUND Masticatory system is a complex functional unit, primarily engaged in chewing, swallowing and breathing functions, and some parts are involved in taste recognition and determination of food consistency. Sophisticated functional performances of speech and emotional expressions are specifically human qualities. Irregularities in occlusion appears to be the precipitating factor in the pathogenesis of myofascial pain dysfunction syndrome. Tek- Scan III records the bite length, number, distribution, timing, duration and the relative force of each tooth contact. It also records the sequence of occlusal contacts in terms of time and the associated force with each occlusal contact. The aim of this study was to treat masticatory muscle disorders with occlusal equilibration, and compare the efficacy of treatment outcomes between selective grinding and stabilization splints using Tek-Scan III. OBJECTIVE Objective of this study was to compare the efficacy of occlusal equilibration achieved through selective griding and stabilization splints using Tek-Scan III. METHODS In this in vivo study, 40 patients with masticatory muscle disorders were selected based on the inclusion and exclusion criteria. The occlusal discrepancies were analyzed using Tek-Scan III. The selected 40 subjects were then randomly divided into 2 groups based on the treatment they recieved; Group I – Selective grinding group (20) and Group II – Stabilization splint group (20). Comparison of pre-treatment and post treatment results were evaluated in terms of pain, mouth opening, left and right side force percentage as recorded through Tek-Scan III and reduction of disclusion time. Statistical analysis was carried out with Kolmogorov Smirnov test, Wilcoxon matched pair test and Mann-Whitney U test. RESULTS Wilcoxon matched pairs test demonstrated that there was statistically significant results ( p = 0.0007) in both the groups for reduction of disclusion time, elimination of pain and improved mouth opening. Patients in Group I showed better results as compared to Group II in terms of disclusion time, pain and mouth opening. CONCLUSIONS Occlusal equilibration brought about by reducing the disclusion time using the Tek- Scan III reduced the symptoms of pain in masticatory muscles. Patients in group I (Selective grinding) however showed better results when compared to patients in group II (Stabilization splints).

Temporomandibular disorder (TMD) encompasses a set of disorders involving the masticatory muscles, the temporomandibular joint and associated structures. It is a complex biopsychosocial disorder with several triggering, predisposing and perpetuating factors. In the etiology of TMD, oral parafunctions, namely bruxism, play a relevant role. The study of bruxism is complicated by some taxonomic and diagnostic aspects that have prevented achieving an acceptable standardization of diagnosis. The aim of this study was to analyze the prevalence of temporomandibular disorders and bruxism in a Portuguese sample.

Introdução: A Disfunção Temporomandibular (DTM) é um quadro patológico que afeta o sistema estomatognático e, frequentemente, acompanhada de dor. Objetivos: Aferir o nível de dor dos pacientes portadores de DTM e a prevalência de sintomatologia articular e muscular. Percebeu-se que a relação entre a origem da DTM e a sintomatologia dolorosa é pouco relatada na literatura. Materiais e Métodos: Trata-se de um estudo descritivo, observacional de corte transversal, desenvolvido com 30 pacientes com DTM, diagnosticado pelo Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). A amostra foi determinada pelas estimativas de atendimento. A associação entre a sintomatologia e a origem da DTM foram verificadas através do teste qui-quadrado, com intervalos de confiança (95%). Foi usada uma ficha clínica para a coleta de dados com idade, gênero e nível da dor, que foi aferido através da Escala Visual Analógica de dor. Resultados: Constatou-se que 26 pacientes eram do sexo feminino e 4 do sexo masculino. Quinze apresentaram idade inferior a 36,5 anos, e os outros uma idade superior a esta. Quanto a origem da DTM, 19 tinham desordem articular e 11 muscular. A categoria moderada foi o nível mais prevalente, seguida do intenso. Determinou-se que não houve associação estatisticamente significante entre as variáveis deste estudo com a DTM. Conclusão: Constatou-se que, os fatores etiológicos analisados isoladamente não influenciam de forma única no desenvolvimento da DTM, mas poderão atuar em conjunto com outros fatores, já que a sua causa é multifatorial.Descritores: Dimensão Vertical; Boca Edêntula; Dor Facial; Síndrome da Disfunção da Articulação Temporomandibular.ReferênciasDworkin SF, LeResche L.

Occlusal changes were important factors in temporomandibular disorder (TMD). It is of interest to evaluate the association of occlusal wear facets in TMD patients. We used a dataset of 49 patients with and without TMD for this study. Occlusal wear facets were evaluated using Smith and Knight tooth wear index. Data shows that teeth wear was present more in patients with TMD (55%). The age group 26-40 years showed high prevalence of teeth wear (grade1) in TMD patients (P value = 0.034). TMD was present more in females than males. Female (54%) patients with TMD showed more teeth wear compared to males. Most patients with TMD showed posterior teeth wear (61%) than generalized teeth wear. Thus, association was present between occlusal teeth wear and TMD patients especially in the age group of 26-40 years. Hence, proper evaluation of occlusal factors will aid in early diagnosis of TMDs.

Level Information

Tooth wear is considered a normal, age dependent, physiological process that leads to the loss of enamel and dentine. However, in some cases the process is so progressive that it may be pathologic. The focus of this chapter is to present the consequences of advanced tooth wear resultant from parafunction, excessive masticatory forces, imbalanced occlusal contacts, and hyperactive masticatory muscles. This chapter also outlines preventative strategies that can predictably reduce the progression of pathologic wear, which employ the T-Scan 8/BioEMG synchronization module. These two objective companion technologies assess the occlusion before, during, and after dental treatment, as well as predictably control the long-term stability of newly installed fixed, implant-supported, or removable prostheses. Their synchronization correlates muscle activity level information directly to occlusal contact force and time-sequencing information, which when applied together in the wear patient can be instrumental in tempering and eliminating pathologic occlusal wear.
