摘要: [摘要] 目的 探讨哈尔滨地区个别正常牙合与骨性Ⅲ类错牙合青年患者颞下颌关节CBCT影像的差异性。方法选取颞下颌关节健康的个别正常牙合志愿者及高角骨性Ⅲ类错牙合患者各40例,两组样本均为哈尔滨地区青年人(年龄为20~28岁)。获取两组牙尖交错位的颞下颌关节CBCT影像,采用Mimics16.0和Simplant O&O软件对颞下颌关节的位置形态进行测量,用SPSS 17.0软件进行统计学分析。结果骨性Ⅲ类错牙合组和个别正常牙合组测量结果比较有8个测量项目有明显差异(P<0.05),分别为MI指数、髁突相对位置、髁突半径值、关节窝深、髁突指数、关节窝指数、两侧关节窝外径、两侧髁突长轴夹角。结论哈尔滨地区骨性Ⅲ类错牙合患者与正常牙合人群颞下颌关节位置形态具有差异。

Abstract: Objective To compare the difference between individual normal occlusion and skeletal Ⅲ class malocclusion young people’s TMJ CBCT images in Harbin. Methods selected health TMJ of individual normal occlusion 40 voluteers and patients with health high-angle skeletal Ⅲ class malocclusion 40 people,The age of young people between 20 to 28 years old in Harbin region.Two groups undergone CBCT in the intercuspal position ,measurement the TMJ morphology and position with Mimics16.0 and Simplant O&O software .The data was analysis SPSS 17.0 software .Results 8 measurements showed significant differences between individual normal occlusion and the skeletal Ⅲ class malocclusion, which were MI,AE′/AC,Condylar radius value,deep of glenoid fossa,index of condyles,index of glenoid fossa,outer diameter of two sides glenoid fossa ,the angle of two sides condylar long axis. Conclusions The morphology and position of TMJ are difference between individual normal occlusion and skeletal Ⅲ class malocclusion in Harbin.
