摘　　要：目的利用CBCT测量并比较不同矢状骨性错高角型成年女性患者的髁突相关参数(体积、表面积、关节前间隙、上间隙及后间隙),为临床提供参考。方法从青岛市口腔医院影像科CBCT资料库筛选骨性错高角型成年女性患者,分为骨性Ⅰ类、Ⅱ1类、Ⅲ类,各30例。将样本的CBCT影像以DICOM3.0医学数字图像通讯标准存储,用软件Mimics10.01读取并进行髁突三维重建,测量上述相关并进行统计学分析。结果 3组左、右侧髁突的相关测量项目差异无统计学意义(P>0.05);对于髁突关节前间隙、关节后间隙,3组间差异均有统计学意义(P<0.05);对于髁突关节上间隙,骨性Ⅰ类与骨性Ⅱ1类间差异无统计学意义(P>0.05),骨性Ⅰ类与骨性Ⅲ类、骨性Ⅱ1类与骨性Ⅲ类间差异均有统计学意义(P<0.05)。结论不同矢状向骨性错高角型成年女性患者的髁突位置具有一定差异性。Objective To measure and compare condyle-related indexes(volume,surface area,anterior space,upper space and posterior space)in adult female patients with different sagittal malocclusions with the aim of providing a reference for clinical treatment.Methods The CBCT database of Qingdao Stomatology Hospital was searched to identify patients with high-angle adult skeletal malformations with the following classifications:classⅠ(n=30),classⅡ(n=30),and classⅢ(n=30).The CBCT images associated with the sample population were stored according to DICOM3.0medical digital image communication standards.Mimics10.01software was used to read and prepare three-dimensional reconstructions of the condylar,and the above-listed indicators were measured and statistically analyzed.Results There were no significant differences between the right and left sides among the three groups(P>0.05).For parameters including condylar anterior joint space and post-joint space,the differences among the three groups were significant(P<0.05).There was no significant difference in parameters related to condylar articular space between classⅠand classⅡ(P>0.05).The differences between skeletal classesⅠandⅢand between skeletal ClassesⅡ,andⅢwere statistically significant(P<0.05).Conclusion Condylar position varies among high-angle adult woman with skeletal malocclusions with different sagittal skeletal patterns.
