目的：比较锥形束计算机体层摄影（cone-beam computed tomography，CBCT）的调查结果、颞下颌关节紊乱（temporomandibular disorders，TMD）患者和非颞下颌关节紊乱患者的关节间隙进行测量，并对研究结果与临床诊断相关性进行研究。方法：使用锥形束计算机体层摄影（CBCT）附带测量软件测量髁突在矢状位、轴位和冠状位的相对位置，并进行双侧髁突位置对称性的比较。结果：关节上间隙（冠状位）的均值为（2.337±0.691）mm；前间隙均值为（1.712±0.691），后间隙均值为（2.727±0.868），内侧间隙均值为(3.878±1.164），外间隙均值为(1.499±0.805)；其中关节上间隙、前间隙、外侧间隙、后间隙，内侧间隙比较，差异均有统计学意义(P＜0.05)。讨论锥形束计算机体层摄影（CBCT）断层扫描结果与TMD的临床诊断有显著关联。结论：健康成年人髁突位于关节窝中位，双侧髁状突位置基本对称；而且颞下颌关节紊乱病患者髁突一般位于后下位，锥形束计算机体层摄影（CBCT）影像测量是评价髁突位置的有效方法之一，也是比较常用的方法。

Objective This study was to compare cone-beam computerized tomography(CBCT) findings and joint space measurement in temporomandibular disorder(TMD)and non-TMD joints,and to correlate these findings with the clinical diagnosis. Methods The study was conducted on 30 cases of patients diagnosed with temporomandibular joint disorder and 30 cases of temporomandibular joint healthy adult volunteers head CBCT scanning,using CBCT measurement software included with the relative position measuring condylar sagittal,axial and coronal,and Comparison of bilateral symmetry condylar position. Results The joint space(coronal)of mean (2.337±0.691)mm;mean before clearance (1.712 ± 0.691),after a mean interval(2.727 ± 0.868),mean medial clearance(3.878 ± 1.164),outer space mean(1.499 ± 0.805);where in the gap on the joint, the former space,outer space,after the gap, the inner gap differences were statistically significant(P<0.05).Discussion Cone beam computed tomography results and clinical diagnosis of TMD were significantly associated. Conclusion Healthy adults condylar located glenoid fossa the median, bilateral condylar position substantially symmetrical;the next bit,CBCT image measurement after temporomandibular joint disorder patients condylar located is one of the effective method to evaluate the condylar position.
