摘　　要：目的:探讨特发性髁突吸收(idiopathic condylar resorption,ICR)患者髁突在三维方向上的位置特征。方法:纳入符合ICR诊断的患者26例为实验组,无TMJ疾患的骨性I类错[牙合]患者26例为对照组,对TMJ行CBCT扫描,用Mimics 17.0行三维重建,测量髁突位置及方向,行统计学分析。结果:实验组与对照组相比,关节上间隙、轴面倾斜角、关节结节倾斜角减小,髁突的矢状面倾斜角变大,对照组及双侧发病组左右侧对比无明显差异(P<0.05)。结论:ICR患者髁突在矢状向上顺时针旋转,在轴面上向前内方向旋转,且髁突上移位。Objective:To investigate the 3 D position and orientation of the mandibular condyle in patients with idiopathic condylar resorption(ICR).Methods:26 patients with ICR and 26 volunteers without TMJ disorders were included.All subjects received CBCT examation of the TMJs,CT slices were used for 3 D reconstruction and measurments of the condyle with Mimics 17.0 software.Then the parameters of condyle were assessed and statistically analyzed.Results:Compared with the control group,the upper joint space,the axial angle and articular tubercle angle of the ICR group decreased(P<0.05),while the sagittal angle of the condyle increased(P<0.05).There was no significant difference between the left and right sides(P>0.05)of the control group and the bilateral ICR group(P>0.05).Conclusion:The condyle of the ICR patients rotates clockwise in the sagittal direction and axial direction,and the condyle moves upward.
