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).
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.
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).
There were difference in condyle position and TMJ morphology between Class I and Class II division 1 malocclusion group in Uygur adult patients.
通过三维锥形束CT（CBCT）比较维吾尔族成人安氏Ⅰ类和安氏Ⅱ类1分类错牙合患者的解剖结构及髁突-关节窝关系差异。
选取64例安氏Ⅰ类和安氏Ⅱ类1分类错牙合患者，对其颞下颌关节进行CBCT扫描。使用SPSS 17.0软件包分析安氏Ⅰ类和安氏Ⅱ类1分类患者髁突形态和位置的差异。
两组患者髁突在颞下颌关节窝中的位置无显著差异；安氏Ⅱ类1分类错牙合组下颌关节窝深度、前间隙和上间隙显著更大（P<0.05），但后间隙显著小于安氏Ⅰ类错牙合组（P<0.05）。
维吾尔族成人安氏Ⅰ类和安氏Ⅱ类1分类错牙合组在髁突位置和颞下颌关节形态上存在差异。
