Research Abstract |
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.
