摘　　要：目的 :分析青春期骨性错[牙合]畸形患者髁突位置与性别及颅面骨骼形态的关系。方法 :使用正畸模拟治疗软件(Dolphin imaging 11.8)对391例15~16岁不同骨性错[牙合]畸形患者的锥形束CT(CBCT)图像进行三维重建,在髁突矢状面上对颞下颌关节前、上、后间隙进行测量并计算髁突相对位置。采用SPSS 23.0软件包分析不同性别、矢状骨面型和垂直骨面型髁突位置的差异,并通过多因素logistic回归模型探讨其关联性大小。结果:单因素分析显示,髁突位置在不同矢状骨面型和性别间具有显著差异(P<0.05)。多因素分析显示,女性发生髁突前移位的可能性是男性的1.942倍(95%CI:1.166~3.236,P=0.011)。2个骨性指标中,右侧关节结节后斜面斜度越大,髁突越易后移,其OR值为1.032 (95%CI:1.000~1.066,P=0.048)。结论:关节结节后斜面斜度可能与髁突后移位有关,女性髁突比男性更易前移。PURPOSE:To analyze the relationship among condylar position and gender and craniofacial bone morphology in adolescent patients with skeletal malocclusion.METHODS:Odontic simulation software(Dolphin imaging11.8)was used to reconstruct cone-beam CT(CBCT)images of 391 patients with different skeletal malformations aged 15-16 years.The anterior,superior,and posterior spaces of temporomandibular joint(TMJ)were measured on the sagittal plane of the condyle to calculate the relative position of the condyle.The difference of condylar position between different genders,sagittal,and vertical skeletal types were analyzed,and the correlation was evaluated by a multivariate logistic regression model with SPSS 23.0 software package.RESULTS:Univariate analysis showed that the condylar position was different between different sagittal facial types and gender(P<0.05).Compared with men,the OR value of anterior condylar displacement in female was 1.942(95%CI:1.166-3.236,P=0.011).The greater of the right articular eminence angle,the easier the condyle moved backward,and the OR value was 1.032(95%CI:1.000-1.066,P=0.048).CONCLUSIONS:The articular eminence angle may be related to the posterior displacement of the condyle,and female condyle is more likely to move forward than male.
