摘　　要：目的 :研究肌位板对下颌位置的调整作用。方法 :对 10 2例颅颌功能紊乱 (CMD)患者均戴用肌位板 ,戴板后 1周、2周、1月各复查 1次 ,以后每月复查 1次 ,共戴板 3～ 6月。记录戴板后是否出现咬合不稳 ,若有咬合印迹变化者则磨去原有咬合印迹重垫 ,直至不再变化 ,待症状消失后去除板 ,轻咬至肌接触位 ,记录与颌位是否协调。结果 :戴板期间 66例患者的咬合印迹始终不变 ,3 6例患者出现咬合不稳 ,经重垫后 ,咬合板的关系稳定不变。待症状消失后去板。 10 2例患者中 ,12例表现为肌牙位不一致 ,其中前牙早接触 2例 ,先天性垂直距离不足 1例 ,牙尖交错位 (ICP)偏位 9例。结论 :肌位板对下颌位置的调整作用是调正肌位 ,在肌位正常情况下 ,判断肌牙位是否一致 ,从而检出 ICP异常。Objective: To study the effects of muscular position splint on maxillomandibular realignment. Methods: The changes of occlusal impression on splint in 102 craniomandibular disorder (CMD) patients were recorded after wearing the splint 1 week , 2 weeks, 1 month, two to three or six months. If there appeared instability of occlusal impression when biting, the original impression was cleared and new soft resin was placed on its surface in order to get a new impression. The splint was always adjusted to fit well. When the signs and symptoms of CMD disappeared, the splint was worn off. Finally, whether the muscular contact position harmonized with the intercuspal position (ICP) or not was recorded. Results: There appeared two different conditions:①The original occlusal impression remained unchanged in 66 patients; ②Being unfitted in 36 patients, occlusal analysis revealed that 12/102 patients had abnormal occlusion including premature anterior teeth contact (2 cases), natural defective vertical dimension (1 case) and deflected ICP (9 cases). These abnormal occlusion could not be determined before treatment. Conclusion: The muscular position splint can correct the abnormal muscular position. On the premise that the muscular position is normal, the muscular position splint can be used to judge whether the ICP is normal.
