The occlusal discrepancy associated with periodontally jeopadized remaining dentition and those supporting structures,caused by partially edentate in molar area,after processing time, decreasing vertical dimension of occlusion, promoting elongation, increasing tooth-mobility without optimal functions, suffers stability of centric occlusion and consecutive lateral excursion. In these conditions,it is quite effective to reconstruct occlusal deficits by splinting-designed RPD.The results of clinically follow-up researches of such patient by EMG-MKG-analyzer were as follows;i) Secondary splinting by RPD stabilizes a centric occlusion and improves equilibration of occlusion with recovery of masticatory function,muscle activity and physiological control mechanisms as the muscle coordination,reveration of EMG-silent periods. ii) Splinting RPD indicates effective occlusal therapy of remaining oral structures.

磨牙区部分无齿导致的牙合不一致在牙周上危害剩余牙列及其支撑结构，处理时间过后，牙合垂直尺寸减小，拉长，牙齿活动性增加，功能不佳，影响正中咬合的稳定性和持续的侧移。应用EMG-MKG分析仪对这类患者的临床随访研究结果如下：1)应用RPD的二次夹板固定稳定了正中咬合，改善了咬合的平衡，恢复了咀嚼功能、肌肉活动和肌电静默期的逆转等生理调控机制。(Ii)RPD支架术是对残存口腔结构进行有效的咬合治疗。
