摘要:
[摘要]目的：通过测量骨性Ⅲ类错牙合畸形面部偏斜不对称患者的牙、骨骼标志点与参考平面之间的线距，研究其与面部偏斜
程度之间的相关性，分析面部偏斜患者的特征。方法：收集符合纳入标准的新疆地区成人骨性Ⅲ类错牙合畸形人群治疗前CT
影像51例(男20例，女31例) ，使用Mimics Research 19.0软件进行CT三维重建，最后在Geomagic Wrap (64 bit)软件辅助
下，测量标志点与三个参考平面之间的线距，采用 SPSS21.0 软件包对数据进行统计分析。结果：偏斜组偏斜侧Rmn、Rma、
Jr、MdF、MtF、U6MB至矢状面（S）的距离大于偏斜对侧，MdF、MtF至冠状面（C）的距离小于偏斜对侧（P ＜0.05）。非偏
斜组除MtF至矢状面（S）的距离有左右侧差异（P ＜0.05），其余测量指标无统计学差异（P ＞0.05）。偏斜组中Me-S与偏斜
侧MtF-S呈极强正相关（r =0.805,P =0.000），与偏斜对侧MtF-S呈强负相关（r =-0.796,P =0.000）。结论：偏斜组除矢状向
不调外，还伴有水平向旋转及牙性代偿，可依据MtF-S判断偏斜程度。非偏斜组患者仅有上下颌骨的矢状向不调，左右侧对
称性较好。

Abstract:
Abstract: Objective By measuring the line distance between the teeth, bone landmarks and reference plane of patients
with skeletal Class Ⅲ malocclusion facial asymmetry, and studying the correlation between these and the degree of facial
asymmetry, the characteristics of patients with facial asymmetry are analyzed. Methods We collected 51 CT images (20 males
and 31 females) of adults with skeletal Class Ⅲ malocclusion in Xinjiang that meet the inclusion criteria, and then used Mimics
Research 19.0 software for CT 3D reconstruction, and finally the line distance between the landmarks and the three reference
planes were measured in Geomagic Wrap (64 bit) .The data were analyzed by SPSS 21.0 statistical software. Results The Rmn,
Rma, Jr, MdF, MtF, U6MB to the sagittal plane (S) is greater than the opposite side in deviated side of the subjects in facial
asymmetry group, the distance from MdF, MtF to the coronal plane (C) is less than the opposite side of the deviation (P ＜0.05).
Except for the distance between MtF and sagittal plane (S), there was a difference between the left and right sides (P ＜0.05)
in facial symmetry group, and there was no statistically significant difference in the other measurement indicators (P ＞0.05).
In the facial asymmetry group, Me-S was strongly positively correlated with the MtF-S in deviated side (r =0.805, P =0.000),
and strongly negatively correlated with MtF-S (r =-0.796, P =0.000 )in the opposite side. Conclusion In addition to the sagittal
discrepancy,the facial asymmetry group is also accompanied by horizontal rotation and dental compensation. The degree of
asymmetry can be judged according to MtF-S. In the facial symmetry group,the upper and lower jaws were unbalanced in
sagittal direction and the bilateral symmetry was better.
