摘　　要：目的:探讨特发性髁突吸收(ICR)患者髁突的三维形态特征。方法:选取符合ICR诊断的患者26例为实验组,无关节疾患的骨性I类错(?)患者26例为对照组,对颞下颌关节(TMJ)行CBCT扫描,利用Mimics 17.0行三维重建,测量髁突大小及形态,并进行统计学分析。结果:实验组髁突体积、表面积变小(P<0.01),前后径、内外径变短(P<0.01),高度降低(P<0.01),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患者髁突相比正常髁突,表现出三维方向上的形态改变,可用来评估ICR的进展、疗效及预后。Objective： To study the three-dimensional characteristics of the mandibular condyle with idiopathic condylar resorption （ICR）. Methods： 26 patients with ICR and 26 volunteers without temporomandibular joint（TMJ） disorders were included. All sub- jects received CBCT examination of the TMJ. Three-dimensional reconstruction of the condyle was conducted by Mimics 17.0 software and the morphologic parameters were measured and statistically analyzed. Results： The condylar volume, the condylar surface, antero- posterior distance, medial-lateral distance and condylar height of the condyle with ICR were smaller than those of the health controls, there was no significant difference between the 2 sides in the controls（P 〉 0.05 ） and in the bilateral onset patients （P 〉 0.05）. Con. clusion： The morphologic change of the mandibular condyle with ICR is characterized by three dimensional decrease.
