摘　　要：目的 :运用锥形束CT(CBCT)探讨维吾尔族错畸形成年患者髁突位置及颞下颌关节形态特征及其差异,为临床诊治提供依据。方法:对64例维吾尔族安氏I类和安氏Ⅱ类1分类错畸形成年患者的颞下颌关节CBCT图像进行分析测量,采用SPSS17.0软件包对颞下颌关节窝间隙、髁突相关指标进行统计学分析,比较安氏I类和安氏Ⅱ类1分类颞下颌关节形态之间的差异。结果:安氏I类和安氏Ⅱ类1分类成年维吾尔族患者髁突在颞下颌关节窝内的位置无性别差异(P>0.05);安氏Ⅱ类1分类患者的颞下颌关节窝前间隙、上间隙及深度均大于安氏I类患者,后间隙小于安氏I类患者;髁突的内外径及前后径在不同矢状骨面型患者中存在显著差异。结论:维吾尔族安氏I类患者的髁突位置及颞下颌关节形态与安氏Ⅱ类1分类患者存在差异,临床诊治过程中应予以重视。PURPOSE： To compare the anatomy and condyle-fossa relationship difference between Uygur adult patients with Class I and Class Ⅱ division 1 malocclusion by three dimensional cone-beam CT （CBCT）. METHODS： Sixty-four patients with Class I and Class Ⅱ division 1 malocclusion were selected, and the CBCT scans of their temporomandibular joints were taken.The difference of the condylar morphology and location between Class I and Class Ⅱ division 1 patients was analyzed with SPSS 17.0 software package. RESULTS： The position of condyle in the TMJ fossa was not significantly different between the two groups; in Class Ⅱ division 1 malocclusion group, the mandibular fossa depth, anterior joint space and the superior joint space were significantly bigger （P〈0.05）, but the posterior joint space was significantly smaller than those in Class I malocclusion group （P〈0.05）. CONCLUSIONS： There were difference in condyle position and TMJ morphology between Class I and Class Ⅱ division 1 malocclusion group in Uygur adult patients.
