Abstract

Abstract: Objective: To realize the fatigue life of taper lock abutment in platform switching implant with different materials. Methods: The image making software was used to set up the three-dimensional finite element models which simulated the platform switching abutment connection with alveolar bone complex. Results: The rank of fatigue life of these different implant abutment materials was titanium＞zirconia＞alumina. Conclusion: The fatigue life of these implant abutment materials were over 30 years. The key factor of different material fatigue life is the point of stress concentration.

Key words: Platform switching, Three-dimensional , Finite element method , Abutment , Fatigue analysis
