摘　　要：目的:研究20名云南籍正常成年人40侧颞颌关节(TMJ)位置及形态特征的基线测量值,为成人错畸形患者的相应研究提供参考数据。方法:利用16层螺旋CT,对20名经过筛选符合研究条件的志愿者的40侧TMJ进行扫描,采用多层面重建(MPR)技术对TMJ进行三维重建及参数测量。结果:40侧TMJ中23侧髁突在关节窝内处于中性位,占53%,前移位者占15%(6/40),后移位者占27.5%(11/40)。左右两侧TMJ骨性结构的参数测量左右基本对称,无显著性差异。髁突前斜面倾角与关节结节后斜面斜度高度相关,相关系数r=0.78。结论:正常成人TMJ骨性形态的左右两侧髁突基本对称,髁突在关节窝中基本处于中性位,有较轻度后移倾向,髁突与关节窝之间具有协调和平衡关系。Objective：To investigate the condyle position and parameters of TMJ Joint conformation of 20 adults with normal occlusioni,n order to provide reference data for follow-up study of adult patients with malocclusion.Method：20 volunteers with normal occlusion were selected and scanned with 16-slice spiral CT.The articular spaces of TMJ and pa-rameters of skeletal morphology of TMJ were measured in the multiplanner reformation（MPR）images.Result：23 condyle of the 40 were in a center position in the glenoid fossa,the rate was 53 %t,he rate of anterior displacement was 15 %（6/ 40）t,he rate of retrodisplacement was 27.5 %（11/40）.The parameters of TMJ bone structure after MPR showed there was no significant difference between the two side joints.The Condyle anterior oblique angle and the tuberculum articulare angle have a high correlation（r = 0.78.） Conclusion：The left and right of TMJ＇s skeletal morphology of adults with normal occlu-sion were basically symmetry.Condyle was located in the center position of the glenoid fossa and they have a slight inclina-tion of retrodisplacement,there was a coordination and balance between condyle and glenoid fossa
