title: Effect of positional loading of three removable partial denture clasp assemblies on movement of abutment teeth.
abstract: Tests demonstrated that the degree of movement of the abutment tooth for a distal-extension base using three different clasp designs was a function of the location of loading. Thus, the null hypothesis, there is no significant difference in the degree of movement of the abutment tooth around the axis of rotation as a function of the position of loading, has been demonstrated to be invalid based on the data obtained in this investigation.
