肌位板对颅颌功能紊乱症状的治疗作用研究

Effect of Muscular Position Splint on Sings and Symptoms of Cranionmandibular Disorders

目的 :探讨肌位板对颅颌功能紊乱 CMD 症状与体征的治疗作用 .方法 :对 10 5例确诊为 CMD者 ,夜间戴用肌位板 3～ 6个月 ,咬合板使前牙平均加高 2 .6± 0 .8mm.结果 :颅颌功能恢复正常者 5 4例 ,占 5 1.4% ,颅颌功能好转 48例 ,占 45 .7% ,无效者 3例 ,占 2 .9% ,肌位板对疼痛的缓解率最高 ,2周内达 90 % ,弹响是最难消除的症状 .其中盘突关系正常者 ,可复性盘前移位者 ,不可复性盘前移位者临床症状消失率分别为 78.8%、42 .1%和 35 .3% .结论 :肌位板是治疗 CMD症状的较好方法 ,有效率达 90 %以上 ,半数 CMD者颅颌功能可完全恢复正常 ,研究同时发现随颞颌关节病变的加重 ,CMD的症状消失率降低 .

Objective:To investigate the effect of muscular position splint (MPS) on signs and symptoms of Craniomandibular Disorder (CMD) patients.Method:105 patients suffering from CMD wore the splint during night for 3 to 6 month with the verticle dimmension increased 2.6±0.8mm on average.Results:51.4% of the patients had their signs and symptoms disappeared complely,and 45.7% relieved.Pain in muscular and/or temporomandibular joint (TMJ) regions were relieved in more than 90% of the patients whthin two weeks,while clicks was the most difficult to be eliminated.In patients with normal Arthrogam(NA),anterior disk displacement with or without reduction(ADDR,ADDWR),the disappearing rate of signs and sympotoms was accordingly 78.7%,42.1% and 35.3%.Conclusion:MPS is effective for 90% of the CMD patients,and half of these patients had their signs and symptoms returned to normal.The results also indicated that accompanied by the increasing lesions in TMJ the cure rate of signs and symptoms of CMD was decreased.
