Fig. 1. Three-dimensional finite element models. Structure of the implant complex and cross-sectional view of the cylindrical bone near the implant (A). The dimensions of three cases of cementless fixation (CLF) implant prosthesis (RAF, RA, and RNA) and cement-retained (CR) implant prosthesis (B). In each system, the magnified part shows the finite element models of thin resin/cement layer and the represented thickness.
