摘要： 目的: 利用CBCT对比TMD患者双侧颞下颌关节,分析髁突-关节窝位置形态与前牙咬合的关系。方法: 对47例患者进行CBCT影像学检查,测量患者双侧关节间隙、关节窝深度。从髁突位置形态变化、关节窝深度,分析患者前牙咬合型与TMD的关系。结果: CBCT显示所有患者双侧关节对称。前牙咬合异常与髁突位置变化有相关性,其中深覆盖深覆牙合患者及深覆盖患者髁突明显后移位(P=0.011,P=0.0004)。前牙咬合正常的患者髁突骨质发生骨关节病的几率增大(P＝0.005)。结论: TMD 的病因复杂多样,咬合异常只是其中一个因素。

Abstract: Objective: To analyze the relationship between the position and morphology of condyle and anterior teeth occlusion by CBCT. Methods: The bilateral joint space and depth were measured to analyze the relationship between anterior teeth occlusion and TMD in 47 TMD patients using CBCT examination. Results: No significant changes were found in bilateral joint in all patients. There was close association between anterior teeth occlusion and condylar position, in which the condylar of overbite combined overjet patients and sole overjet patients were moved backward (P= 0.011 and P=0.0004). The incidence of osteoarthrosis was increased in patients whose anterior teeth occlusion was normal (P=0.005). Conclusion: The etiology of TMD is complex and multifactorial. Occlusal condition is just one factor.
