摘　　要：目的研究RW板治疗颞下颌关节紊乱病(TMD)前后髁突位置的改变,以探讨RW板的治疗机制。方法选择2016年1—7月在福建医科大学附属口腔医院正畸科就诊的TMD患者20例,在RW板治疗前后分别拍摄颞下颌关节锥形束CT(CBCT),并测量患侧髁突的关节间隙。比较治疗前后关节上、前、后间隙的改变。结果治疗后患侧髁突的关节前间隙减小、后间隙增大,差异有统计学意义(P<0.05);关节上间隙的改变差异无统计学意义(P>0.05)。结论 RW板可使髁突向前移动,使髁突趋于关节窝正中。Objective To investigate condylar position before and after occlusal splint treatment in patients with temporomandibular disorders（TMD）and to study the treatment mechanism. Methods Twenty patients with TMD were chosen from January to July 2016 in the Department of Orthodontics,Hospital of Stomatology,Fujian Medical University.The image of cone-beam computed tomography（CBCT）was photographed before and after RW splint treatment. Measurements of the spaces of TMJ were made to compare the change of condular position. Results Anterior space decreased but posterior space increased after treatment by occlusal splint（P〈0.05）,but there was no statistically significant chang in superior space（P〉0.05）. Conclusion After the occlusal splint treatment,the condyle may move forwards to get centered in glenoid fossa.
