维吾尔族错畸形患者髁突位置及颞下颌关节形态的锥形束CT研究

摘要/Abstract

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。

Abstract: 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.
