Abstract: Objective: To present a good procedure to generate a three-dimensional finite element model of platform switching implant with different materials for biomechanics researches. Methods: The image making software was used to set up the three-dimensional finite element models simulated platform switching abutment connection with alveolar bone complex. Results: The SDD high precision scanner was used to get the accurate shape of the model and keep the wholeness sample. The model had high geometric similarity and the similarity mechanics, and it could reflex the problem of this experiment. Conclusion: The highly-accurate model can be acquired with the help of high precision scanner and PRO-E software.
