Nonlinear finite element analysis of three implant–abutment interface designs

Abstract

Modeling of dental implant systems with nonlinear finite element analysis (FEA) can differentiate their resistance to physical stress. Chun-Bo Tang of Nanjing Medical University, China, along with dental and engineering colleagues in Nanjing, tested the FEA method in a study of three commonly used designs of implant from different countries. In three dimensions, they simulated the stresses of a force of 170 newtons exerted at an angle of 45° onto the top of the attachment point or abutment of each system. From their results, Tang and colleagues concluded that none of the implants was likely to fail under such a force. The way the implants distributed stress, however, suggested that the design from the USA was superior to those from Germany and Sweden, and was likely to be displaced a smaller distance when in use.
