The role of the occlusion in the etiology and prevalence of temporomandibular disorders (TMD) has not been conclusively demonstrated. Occlusal factors and condyle position asymmetry as deduced from computed tomography (CT) axial scans were correlated with signs and symptoms of TMD in 49 young adults (mean age 24 years, range 15-33 years) with complete or almost complete dentition. A statistically significant correlation was noted between these signs and symptoms and occlusal variables describing asymmetry (the amount and lateral deviation of the slide from 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.
咬合在颞下颌关节紊乱病（TMD）病因及患病率中的作用尚未得到确凿证实。通过计算机断层扫描（CT）轴向扫描推断出的咬合因素和髁突位置不对称与49名牙列完整或几乎完整的年轻成年人（平均年龄24岁，范围15 - 33岁）的TMD体征和症状相关。这些体征和症状与描述不对称性的咬合变量（从后退接触位（RCP）到牙尖交错位（IP）的滑动量和侧向偏差以及前伸偏差和双侧尖牙咬合不对称）之间存在统计学上的显著相关性。似乎咬合差异可能是TMD的一个易感因素，尤其是当它以不对称形式表现时。
