摘要：  目的： 研究咬合板加局部激光照射对颞下颌关节紊乱病（TMD）的临床治疗效果。方法： TMD患者225例，随机分为咬合板+局部激光照射组、局部封闭治疗+局部激光照射组、局部激光照射组，每组75人。局部封闭治疗：2%利多卡因1 mL+醋酸强的松龙混悬液2 mL行痛点封闭，每周1次，3～5次为一疗程。咬合板治疗：夜间佩戴下颌平面抬高约4 mm的咬合板。激光治疗：用MDC?鄄500IP型半导体激光治疗机照射颞下颌关节区，1次/d，10 d为一疗程。结果： 总有效率“咬合板+局部激光照射组”为93.33%，“局部封闭治疗+局部激光照射组”为85.02%，“局部激光照射组”为70.67%。组间差异有统计学意义（P<0.05）。结论： “咬合板+局部激光照射”治疗TMD较为有效，值得推广。

Abstract: Objective: To evaluate the clinical effects of occlusal splint and local laser irradiation in the treatment of temporomandibular disorders. Methods: 225 temporomandibular disorder(TMD) patients were randomly divided into 3 groups (75 patients in each) and their treatment results  were retrospectively reviewed. In group A,  occlusal splint and  local laser irradiation were used. In group B, a local block injection were used combining with local laser irradiation. In group C, local laser irradiation were used only. Block injection solution was 1 mL 2% lidocaine and 2 mL acetic prednisolone suspension once a week for 3-5 weeks. An occlusal splint was fabricated to elevate mandible occlusal level for 4 mm at night. MDC-500IP semiconductor laser construction was used to irradiate temporomandibular joint area once a day and  10 days as a period of treatment.  Results: The effective rate of group A、B、C were 93.33%, 85.02% and 70.67% respectively. Conclusion: The occlusal splint combined with local laser irradiation may be a comparatively beneficial treatment for TMD, which is worthy clinical application.
