Abstract: To investigate the biomechanical effects of three removable partial dentures，the 3D finite element analysis(FEA) models of the mandible with molar missing, rehabilitated using traditional, RPI and implantsupported removable partial denture, were built based on models from the Mechanical Virtual Human of China database. The FEA was conducted in ABAQUS6.51. Two types of forces, vertical and oblique force, were loaded on these models. The FEA results suggest that the RPI removable partial denture is more helpful than the traditional RPD against the vertical and oblique loads, and the implantsupported RPD is more helpful than the other two, especially under oblique loading.
