摘　　要：目的 :分析颞下颌关节紊乱病患者的关节盘前移位的程度的相关因素。方法 :颞下颌关节紊乱病患者 90例 ,在关节造影片上测量关节盘前移位的角度 ,分析关节盘前移位的角度与临床症状、关节骨质变化和髁状突位置的关系。结果 :①可复性盘前移位者的AOB角显著小于不可复性盘前移位组 (P <0 .0 1) ,疾病的迁延 ,没有导致盘移位程度的增大 ;②与可复性盘前移位相比 ,不可复性盘前移位患者慢性期开口度明显变小 ,关节盘前移位的程度更大。结论 :关节盘前移位以及髁状突在关节窝内的非正中位置特征 ,可能与关节组织结构的改建有关。Objective: To investigate the factors related to the of disc displacement in temporomandibular joint disorder(TMD). Methods: The angles of disc anterior displacemen were measured on arthrography of temporomandibular joints in 90 patients with TMD, then the relationship between the angles and symptoms, signs, condyle positions, osteoarthrosis and mouth opening degree were analysed. Results: ①AOB angle in the patients with reducibility of anterior disk displacement(ADwR) was smaller than in those with non reducible anterior displacement (ADw/oR); ②Patients suffered from chronic ADw/oR had smaller degree of mouth opening and larger disc displacement than those with ADwR's. Conclusion: The disc anterior displacement and condyle displacement in glenoid fossa may be correlated with articular remodeling.Prolonging coursees may not always result in the changing of disc structures.
