Abstract： 目的 通过记录下颌偏斜患者的髁突运动轨迹,研究此类患者髁突运动的规律.方法 下颌偏斜患者31例(男性9例,女性22例),年龄12～26岁,平均18岁.使用CADIAX Ⅲ型髁突运动轨迹轴图描计仪,记录并通过配对t检验和秩和检验分析患者下颌侧方运动时髁突的运动轨迹,并将其与患者下颌偏斜量进行多元线性回归分析.结果 下颌偏斜患者下颌侧方运动时髁突的运动轨迹不对称,偏斜侧的运动位移大于非偏斜侧,差异有统计学意义(P＜0.01);偏斜侧髁突的水平倾斜度小于非偏斜侧,差异有统计意义(P＜0.01).随着偏斜量的增加,偏斜侧与非偏斜侧髁突的位移差距也相应增加,非偏斜侧髁突的位移相应减小,差异有统计学意义(P＜0.05).结论 下颌偏斜患者不仅颅面形态不对称,下颌侧方运动时髁突运动轨迹在长度、角度等方面也不对称,其与偏斜量有一定的相关性.
