摘　　要：目的 :了解北京地区形态正常人群颞下颌关节的形态特点。方法 :自 370 0人中筛选出正常成人 75例 ,(其中男 34例 ,女 4 1例 ,年龄 17 2 4岁 )通过严格的TMJ临床检查将之分为健康关节组和TMD患者组 ,利用计算机技术对其ICP位颞下颌关节标准薛氏位片进行测量分析。结果 :正常成人髁突位置及关节窝形态性别差异不明显 ,双髁突位置及关节窝形态基本对称 ,使用张震康法时 ,健康关节组 1n(P/A)均值为 0 16 39,TMD组 1n(P/A)均值为 0 0 5 2 2 ;使用Cohlmia法时 ,健康关节组 1n(P/A)均值为 0 1939,TMD组 1n(P/A)均值为 0 0 0 79,且两组间均存在显著性差异 ,关节窝形态在健康关节组与TMD患者组不存在显著差异。结论 :有TMD症状的正常成人髁突在关节窝中的位置比具有健康颞下颌关节的正常成人显著偏后。前者髁突多接近居中位 ,而后者的髁突多为稍偏前位。Objective:To investigate the morphologic characteristics of TMJs of adult subjects with normal occlusion in Beijing aera Methods:Seventy five adults with normal occlusion(34 males,41 females)were selected,aging from 16 to 25 years old,divided into healthy and TMD groups.TMJ transcranial lateral oblique radiographs were taken and analyzed with the computer aided diagnosis and management system.Results:Condyle fossa relationship and morphology of glenoid fossa were found no significant difference between genders.Bilateral condylar position and glenoid fossa configeration were found fundamentally symmetric.According to ZhangZhenkangs method,the mean value of ln(P/A) of TMD group was 0 0522;while that of healthy group was 0 1639;Using Cohlmias method,the mean value of ln(P/A) of TMD group was 0 0079;while that of healty group was 0 1939.These differences were found significant between two groups.Conclusion:The study showed that condylar positon in the glenoid fossa of adult subjects with TMJ symptoms were more posterior than that of normal adult subjects.Most condyles of TMD group were nearly concentric,while condyles of healthy group positioned more anteriorly.
