Abstract Purpose: The present study was done to evaluate the effects of different types of abutments on the rate and distribution of stress on the bone surrounding the implant by dynamic finite element analysis method.Material and methods: In this study two ITI abutment models, one-piece and multi-piece, along with fixture, bone and superstructure have been simulated with the help of company-made models. Results: The Maximum Von Misses Stress (MVMS) was observed in the distobuccal area of the cortical bone near the crest of implant in two implant models. In the multi-piece abutment MVMS was more than the one-piece model (27.9 MPa and 23.3 MPa respectively).Conclusion:Based on the results of this study it can be concluded that the type of abutment has influence on the stress distribution in the area surrounding the implant during dynamic loading.
