Objective.本病例对照研究的目的是调查髁突的大小，形状和关节面角度表现出特发性髁突吸收（ICR）与不同程度的髁突骨丢失，并提供额外的信息，为诊断ICR。共纳入ICR患者的154个髁突和42个健康髁突。根据髁状突形态，ICR组进一步分为3个亚组（ICR I、ICR II和ICR III）。利用锥形束CT数据，利用Mimics软件对髁状突的三维模型进行测量和分析。ICR组髁突前后径、横径、高度、表面积、体积、关节面角、髁突颈角、最大截面积、髁突颈截面积与对照组比较差异均有统计学意义（P < .05）。3个亚组之间的许多参数也存在显著差异（P <0.05）。随着疾病的进展，ICR的形态学变化变得更糟，患病和正常髁突之间存在显著差异。各亚组之间存在许多显著差异。后倾髁颈和细长髁颈可能与ICR相关。
Objective. The aim of this case control study was to investigate the sizes, shapes, and articular surface angles of condyles exhibiting idiopathic condylar resorption (ICR) with different degrees of condylar bone loss and to provide additional information for the diagnosis of ICR.Study Design. In total, 154 condyles from patients with ICR and 42 healthy condyles were included. The ICR group was further divided into 3 subgroups (ICR I, ICR II, and ICR III) based on the morphology of the condyle. Three-dimensional (3-D) models of the condyles were measured and analyzed by using the Mimics software based on cone beam computed tomography data.Results. The condylar anteroposterior diameter, transverse diameter, height, superficial area, volume, articular surface angles, condylar neck angle, maximal sectional area, and condylar neck sectional area were all significantly different between the ICR group and the control group (P < .05). There were also significant differences among the 3 subgroups in many of these parameters (P < .05).Conclusions. Morphologic changes in ICR become worse as the disease progresses, with significant differences between diseased and normal condyles. There were many significant differences among the subgroups. Posteriorly inclined condylar neck and slender condylar neck may be associated with ICR.
