Effect of implant position on the masticatory efficiency of mandibular implant retained partial over dentures

Abstract

Removable partial dentures restoring free end saddles are subjected to vertical, horizontal and torsional forces that may become an adverse during functional and Para functional activities. The problem of disparity of support in distal extension prosthesis has always been a challenge for the prosthodontist, the problem arises from the lack of posterior abutment and the difference in the elastic behavior of supporting structures, the abutment teeth and the ridge
