This study compared the peak isometric strength of the cervical flexors in deep bite temporomandibular dysfunction (TMD) patients while biting in four bite positions: habitual occlusion, edge-to-edge, lateral shift and retruded. These values were then compared to those of the same subjects’ bite positions elevated to a functional criterion (maximum isometric strength of the deltoid muscles). The mean height increase was 2.4 mm with a range of 1.5-3.8 mm. Fifteen of eighteen ...

The objective of this study was to investigate condylar position during different degrees of disk displacement. The degree of disk displacement was evaluated on 1.5 Tesla high-field sagittal MR images of 76 joints (48 patients; mean age 19.4 years) and was classified into three grades (1 to 3). To establish condylar position, the anterior, superior and posterior joint ...

The purpose of this research was to examine the relationship between horizontal condylar angulation and position and joint status in an adolescent population. Submentovertex (SMV) radiographs and MRI (magnetic resonance images) of 95 subjects (56 females and 39 males) between the ages of 10-17 years (mean age 13.3 years) were used for this study. Horizontal condylar angulation as well as A-P and transverse condyle position were determined in relation to a cranial base reference ...

In long face syndrome with skeletal open bite, strongly associated with temporomandibular disorders (TMDs), the trajectories of an incisal point are completely different. It was demonstrated by a longitudinal study that, in these cases, the Articular Compass cephalometric analysis is helpful in the construction of bioelastic appliances to provide a better location for frontal accessories, and thereby in most cases ...

One of the roadblocks to success in treating temporomandibular joint dysfunction (TMD) patients is an accurate diagnosis. The terms “TMJ” or “TMD” are not specific enough to provide definitive treatment. Initially the disorder must be classified as a muscular or an internal derangement problem. Once accomplished, the further diagnostic breakdown of the problem will prepare the patient and the doctor ...

This study was conducted in order to determine the effects of body position on integrated electromyographic (IEMG) activity of anterior temporal and suprahyoid muscles. The study was performed on 15 patients with myogenic cranio-cervical-mandibular dysfunction (CMD) and 15 healthy subjects. IEMG recordings at rest and during swallowing of saliva and maximal voluntary clenching were performed by placing surface electrodes on ...

When the signs and symptoms of temporomandibular joint disorders (TMD) are present, the possibility that occlusal position and mandibular movements are changed is considerable. Accordingly, the presence of occlusal interferences may be misjudged. It is therefore reasonable to consider that occlusal conditions should be examined just after the relief of symptoms. A comparison of occlusal condition in 45 patients with eminence clicking with a group of 60 asymptomatic controls was made. An occlusal examination was ...
