Theraptic occlusal function in geriatrically maturated partially edentate mouth by removable partial denture

磨牙区部分牙列导致的牙合差异与牙周危害相关的剩余牙列及其支撑结构，经过时间的处理，使咬合的垂直尺寸减小，促进伸长，增加了牙齿的活动能力，但没有最佳的功能，影响了中心咬合的稳定性和连续的侧向偏移。在这种情况下，用夹板设计的RPD重建咬合缺损是非常有效的。emg - mkg分析仪对该患者的临床随访研究结果如下：i) RPD的二次夹板稳定中心型咬合，改善咬合的平衡，恢复咀嚼功能、肌肉活动和肌肉协调等生理控制机制，恢复肌电沉默期。ii)夹板RPD表明对剩余口腔结构进行有效的咬合治疗。

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.
