The hypothesis, “dental occlusion plays a significant causal role in temporomandibular disorders”, has been a central point of contention for many decades in the attempt to understand these disorders. Recently, certain authors have asserted that the scientific literature does not support this hypothesis. Yet many clinicians working in the TMD arena continue to believe that various dental occlus...

Masticatory movements are studied for decades in odontology; a better understanding of them could improve dental treatments. The aim of this study was to describe an innovative, accurate, and systematic method of analyzing masticatory cycles, generating comparable quantitative data. The masticatory cycles of 5 volunteers (Class I, 19 ± 1.7 years) without articular or dental occlusion problems w...

The effect of vertical dimension of occlusion (VDO) on maximizing isometric deltoid strength (IDS) was measured in subjects with deep overbite. Sixteen female dental students with deep dental overbite and no history of temporomandibular joint disorder (TMD) were used as their own control and tested for isometric strength of the deltoid muscles, using a hand held strain gauge. Measurements were ...

The application of a virtual dental patient with dynamic occlusion during esthetic restoration in digital workflow is described. An intraoral scanner, facial jaw motion analyzer, and cone beam computed tomography were used to transfer data construct the patient. With aid patient, predictability accuracy can increase throughout treatment, simplifying clinical evaluation prosthesis adjustment imp...

INTRODUCTION In this study, we investigated tooth-wear patterns in adolescents with either normal occlusion or Class II Division 2 malocclusion. METHODS The sample consisted of dental casts from 165 subjects that were divided into 2 groups: 115 normal occlusion subjects (mean age, 14.3 years) and 50 complete Class II Division 2 subjects (mean age, 13.9 years). Dental wear was assessed by usin...

Extensive oral processing of food through dental occlusion and orbital mandibular movement is often cited as a uniquely mammalian trait that contributed to their evolutionary success. Save for mandibular translation, these adaptations are not seen in extant archosaurs or lepidosaurs. In contrast, some ornithischian dinosaurs show evidence of precise dental occlusion, habitual intraoral triturat...

abstract introduction. the study for beauty can be traced back to the earliest civilizations. many factors influence the perception of beauty, and esthetic dentistry continues to grow as a major part of overall dentistry. one of the most important factors in beauty of the teeth is the proportion of them to one another, and golden proportion is determined to be 1.618. the purpose of this study w...

In part 1 of this study, it was discussed that dental occlusion/temporomandibular joint (TMJ) status is functionally connected to general body health. The purpose of this part of the study was to attempt to formulate a conceptual account, the "fascial connection theory for TMJ and other parts of the body," to explain the functional connection between TMJ and other parts of the body. The first h...

The present study was performed on dental casts and lateral cephalometric films of 30 Caucasian Brazilian individuals (15 males and 15 females) aged 18 to 27 years and 4 months, all presenting normal occlusion and satisfactory facial profile. The aims were to investigate the existence of dental discrepancies according to Bolton's criteria, to obtain mean values for overbite, overjet, curve of S...
