Abstract: The mechanical stimulus generated by the masticatory forces are necessary to avoid atrophy of the peri-implant bone. The objective of this work is to determine the influence of the porosity of a dental implant on the stress and strain levels generated in the peri-implant cortical and trabecular bones. To carry out the study, a new double-threaded porous dental implant model was used, with variations in porosity levels. The biomechanical behavior of the models was evaluated using the Finite Element Method (FEM), in a maxillary segment with bone quality II, corresponding to the area of the first premolar. In the simulations, static loads were applied to the crown, in the retarded load condition. It was found that the models generated areas with stress and strain peaks at levels higher than those recommended, a behavior accentuated in the implant with greater porosity. However, in both models, most of the forces and deformations generated in the peri-implant bone present levels that must maintain bone density.
