摘　　要：目的了解关节盘前移位在无症状青年志愿者中发生率,并探讨其颞下颌关节盘和髁突的位置关系。方法根据D race标准确定无症状志愿者中关节盘前移位,并进行分组以及定点和相关数据的测量以确定盘-髁关系,对测得数据进行统计分析。结果 30名无症状志愿者中有7人(23.33%)存在单侧可复性关节盘前移位;髁突发育异常者2人(6.67%);双侧均正常者21人(70.00%)。关节盘-髁突位置的测定数据在各组间有统计学意义。结论磁共振影像检查证实在无症状青年志愿者中存在关节盘前移位。Objective To master the incidence of anterior disc displacement of TMJ in symptomless youth volunteers,and approach the relationship between temporomandibular joint disc and the condyle.Methods Diagnose the anterior disk displacement in the asymptomatic volunteers on the basis of Drace standards,divide them into different groups,locate the point measure the related data and then analyze the data,statistically.Results Among the 30 asymptomatic volunteers,7 volunteers had one-side anterior disk displacement（23.33%）;2 volunteers′ condylar process developed anomaly（6.67%）;21 volunteers were normal on both sides（70%）.There are significant differences between the groups on the relationship of temporomandibular joint disc and condylar process.Conclutions Anterior disk displacement exists in asymptomatic young volunteers,which provides a basis to the study of tempormandibular joint disease.
