Effect of two clasping assemblies on arch integrity as modified by base adaptation

Abstract

It is quite apparent from the results of this experiment that the importance of tissue support for distal-extension removable partial dentures cannot be overstated. It would appear that good adaptation of the base far outweighs the importance of clasp design on a well-fitting framework for a distal-extension removable partial denture. When appropriate, regular recall evaluation of removable partial dentures and implementation of indicated readaptive procedures are not available, close base adaptation can be lost because of ridge resorption. As this loss occurs, the clasp design begins to play an increasingly influential role in abutment tooth movement during function.
