In ten healthy subjects, bilateral contacts between opposing cuspid and first molar teeth were recorded during one sequence of unilateral chewing of apple, peanuts, and banana. Unknown magnitudes of mechanophysical (masticatory) forces were inferred to act directly on the chewing-side cuspid teeth in 71% of all masticatory cycles and on the nonchewing-side cuspid teeth in 68% of all masticatory cycles. In addition, unknown magnitudes of mechanophysical forces were inferred to act directly on the chewing-side ...

Recently many postural diseases have been classified among occlusal-functional alterations, mostly on a clinical basis. However some anatomic and physiologic aspects are still unknown. The purpose of this study was to review the literature and to support the correlations by means of a balance platform on a group of 50 patients (30 males and 20 females, mean age 25.8 years) belonging to every Angle classification of malocclusion. The subjects were asked to stand on ...

Objective of this study was to evaluate the diagnostic value of 3-D computed axiography to detect anterior disk displacements (ADD) of the TMJ. 65 patients with MRI confirmed ADD with reduction and 27 patients with ADD without reduction were examined by 3-D computed axiography. 44 healthy volunteers with normal disk position and joint function served as controls. A descriptive analysis of the axiographic opening/closing cycle revealed significantly higher rates of abrupt deviations, accelerations/decelerations ...

Range of motion is used in the examination and diagnosis of many joints. A simple method to measure and record temporomandibular joint range of motion is presented. Correlation of mandibular movement to excursive or lateral movements for a healthy population is described. The maximum incisal opening and lateral movements of 75 subjects, aged 20-50 years, were recorded. The average of maximum opening to lateral movements was found to be 4.4 to 1. A significant ...

Sixty-eight patients ( seven men, 61 women) treated for disk displacement without reduction with extraoral mandibular manipulation followed by splint insertion, physical and drug treatment as needed, were re-examined at the end of treatment and after a subsequent period, ranging from 18 to 147 months. Two parameters were considered: 1. degree of spontaneous mandibular opening; and 2. presence of pain (score 1-4). Mean opening was 28.78 mm before treatment, 42.85 mm after treatment and ...

 In the first part of this series of two papers, the bursa of the tendon of the tensor veli palatini muscle was demonstrated and described histologically. In Part II, the symptoms and the process of diagnosis of bursitis of the hamular process is presented. Additionally, recommended treatment options will be discussed. The article presents three case reports.

As it specifically pertains to temporomandibular disorders (TMD), this article is an educational analysis and discussion of some recently proposed diagnostic criteria, diagnostic methods, and diagnostic decision processes. On the basis of a discussion of classic probability theory, classic measurement theory, and examples using nonparametric inferential statistical tests, it is suggested that certain TMD diagnostic criteria and methods, and their ...

From the late 1970s until the early 1990s, there have been several reports of improved appendage muscle strength and athletic performance. Much of the criticism of using a mouthguard alone or in conjunction with a splint, such as a mandibular orthopedic repositioning appliance (MORA), to enhance athletic performance has been aimed at study designs, controls, periods of time, double blindness, and the placebo effect. Although it would appear that designing a study which pleases both ...

Intra/interrater’s reliability of the coordinates of ten anatomical landmarks on a frontal and a dorsal body posture photograph of 18 subjects was tested. The measurements were conducted by two testers with an interval of seven days between each session. The repeated measurements of each examiner (intrarater) and the first and second measurement of both examiners (interrater) were assessed ...

The pupose of this snoring/sleep apnea study was to assess the role of 3-D magnetic resonance imaging (MRI) of the airway correlated to jaw reposturing/intraoral appliance design. A clinical case is presented utilizing this technology, integrating a diagnostic baseline and follow-up sleep study/polysomnograph. The baseline polysomnography, prior to jaw repositioning appliance design, indicated a respiratory disturbance index (RDI) of 21.5 hypopnea/apneas per hour. The follow-up sleep study, with use of ...
