摘　　要：为研究AngleⅡ2错髁突运动规律,选择45例志愿者随机分成2组,用髁突描记仪记录每位志愿者的髁突运动。AngleⅡ2错开闭口运动时双侧髁突的前后向最大移动量和最大空间位移量均小于正常;向右侧方运动时,右侧髁突的前后向最大移动量大于正常,差别有统计学意义。AngleⅡ2志愿者髁突运动轨迹较典型,以开闭口轨迹矢状位移小为主要特点。15 cases with Angle Ⅱ^2 malocclusion without TMD（ I12 group） and 30 volunteers with normal occlusion（ normal group） were enrolled. Condyle movement was recorded during mandibular movement with computer aided diagnosis axiograph （CADIAX）. During open/ close movement, The condyle movement was significantly smaller in Ⅱ^2 group than that in normal（P 〈 0.05）. During mediotrusion/right movement, the right sagital distances were smaller in U 2 group than in normal. These findings suggest that the tracings of condyle movement in the subjects with Angle Ⅱ^2 malocclusion have classical characteristics, especially the sagittal distance of movement is smaller during open/ close movement.
