研究肌位咬合板对颅颌功能紊乱患者下颌运动的影响。方法：采用下颌运动轨迹描记信，记录99例患者戴板前和即刻置入咬合板后自姿势位（MPP）至牙尖交错（ICO）、自然张闭口及最大最快张闭口运动；孪-吞个月后复查（不戴板）。结果：戴板后87．8％CMD患者由MPP闭合至ICO侧后移消失，自然张闭口轨迹一致率由戴板前4％提高到78.8％，最大最快张闭口运动轨迹规则度由15.2％提高至89.9％,速度也显著增加（P＜0.05）.复查显示:咬合正常者MPP至ICP侧后消失,张闭口轨迹一致,速度轨迹规则,速度增加,咬合异常者下颌运动与治疗前相比无变化.结论:肌位咬合板对CMD治疗机理之一是调整异常的下颌运动.
To study the effects of muscle-occlusal plate on mandibular motion in patients with craniofacial dysfunction. Methods: The mandibular movement track records were used to record 99 MPP to ICO, maximally maximal and maximal maxillary maxillary closure in 99 patients before and after the insertion of bite plates. Review after months (no wear plate). Results: After wearing, 87.8% of patients with CMD disappeared after MPP closure to the ICO side, and the consistency rate of natural opening and closing track increased from 4% to 78.8% and the regularity of maximum and slow opening and closing mouth movement increased from 15.2% To 89.9%, the speed also increased significantly (P <0.05) .Review showed: normal occlusion of MPP to ICP side disappeared, open mouth closed trajectory, speed trajectory rules, increased speed, abnormal occlusion of mandibular movement compared with before treatment Change.Conclusion: One of the mechanisms of CMD treatment is to adjust the abnormal mandibular movement.
