International Journal of Medical Dentistry 57 Gnathology OCCLUSION TIME IN CRANIOMANDIBULAR DISFUNCTION VS. USUAL PROSTHETIC PATIENTS
The currently available data about the role of occlusion in the etiology of TMD's indicate that the occlusal factors seem to be of minor importance. However, some opinions emphasize the importance of individual occlusal features in the etiology of myogenous craniomandibular disorders. The present investigation aims at assessing the differences concerning the occlusion time (OT) in fixed-prosthodontic patients with craniomandibular signs and symptoms versus patients without this disfunction.
... is disfunction. Materials and methods. 37 patients, divided into two groups, who received prosthodontic treatment with fixed partial dentures more than six months ago, were examined by the T-Scan III occlusal analysis system. For each subject, the time elapsed from the first occlusal contact to complete intercuspation (OT) was analysed by system's software. Results and discussion. A significant difference was observed between the two groups regarding the OT values (p = 0.0299), the recorded OT in the disfunction group being longer than in subjects representing the usual prosthetic patients. Conclusions. The subjects with craniomandibular disfunction signs or symptoms are more likely to have an extended occlusion time, compared with the patients with no disfunction signs.
