摘　　要：目的:探讨CBCT在评价骨性安氏Ⅲ类错颌患者双颌术后1年髁突位置变化中的应用。方法:收集15例行双颌术治疗的骨性安氏Ⅲ类错颌患者的CBCT资料,应用Mimics 20软件将术前评估及术后1年图像重建并配准髁突模型,记录并分析双侧髁突位置变化情况。结果:骨性安氏Ⅲ类错颌双颌术后右侧、左侧髁突轴位内外旋转分别为(1.24±2.08)°、(3.17±2.56)°,与术前比较差异均有统计学意义(均P<0.05);术前与术后的髁突内外向、前后向及上下向移位差异均无统计学意义(均P>0.05);术前与术后矢状位前后旋转及冠状位内外旋转情况差异均无统计学意义(均P>0.05)。结论:通过CBCT及Mimics 20软件可发现骨性安氏Ⅲ类错颌患者双颌术后1年发生髁突轴位内旋转。Objective:To investigate the change of condylar position of skeletal classⅢmalocclusion with bimaxillary orthognathic surgery.Methods:The CBCT images data of 15 patients who with skeletal classⅢmalocclusion with bimaxillary orthognathic surgery were collected.Preoperative images and one-year postoperative images were reconstructed and registrated with software Mimics 20.Results:The interior and exterior rotation in axial of the bilateral condyle position were significant different between pre-and post-operation(both P<0.05).The anterior and posterior displacement,the interior and exterior displacement and the superior and inferior displacement of the condyle position were no significant differences between pre-and post-operation(all P>0.05).The anterior and posterior rotation in sagittal and the interior and exterior rotation in coronal of the condyle position were no significant differences between pre-and post-operation(all P>0.05).Conclusion:The condyle position of skeletal classⅢmalocclusion with bimaxillary orthognathic surgery was rotated interior in axial.
