44 normal adults were strictly selected from 450 subjects. Fully corrected lateral tomograms and individual corrected transcranial radiograms were taken in the intercuspid position. The area and linear measurements of the joint space were performed with the aid of a computer. 70 TMJs of the fully corrected lateral tomograms were included in the present study. The measurements of joint space area showed that the normal condylar position is in the center of the fossa basically. However, obvious variations of the condylar position could be seen. Therefore, the concentric position was not the only normal physiological position of the condyle.
从450名受试者中严格筛选出44名正常成年人。在尖牙间位置拍摄全校正侧位断层片和个体校正经颅X线片。借助计算机对关节间隙进行面积和线性测量。本研究纳入了70例全校正侧位断层片的颞下颌关节。关节间隙面积测量结果显示，正常髁突位置基本位于关节窝中心。然而，可以看到髁突位置存在明显变化。因此，同心位置并非髁突唯一的正常生理位置。
