Am. Raustia et al., CORRELATION OF OCCLUSAL FACTORS AND CONDYLE POSITION ASYMMETRY WITH SIGNS AND SYMPTOMS OF TEMPOROMANDIBULAR DISORDERS IN YOUNG-ADULTS, Cranio, 13(3), 1995, pp. 152-156
The role of the occlusion in the etiology and prevalence of temporoman
dibular disorders (TMD) has not been conclusively demonstrated. Occlus
al factors and condyle position asymmetry as deduced from computed tom
ography (CT) axial scans were correlated with signs and symptoms of TM
D in 49 young adults (mean age 24 years, range 15-33 years) with compl
ete or almost complete dentition. A statistically significant correlat
ion was noted between these signs and symptoms and occlusal variables
describing asymmetry (the amount and lateral deviation of the slide fr
om the retruded contact position (RCP) to the intercuspal position (IP
), deviation of protrusion and asymmetry in bilateral cuspid occlusion
). It seems that occlusal discrepancy can be a predisposing factor to
TMD, especially when it is asymmetrically expressed.
