Objective: To evaluate two proposals of external geometry of dental implants observing the influence on the stress distribution.
Methods: It was performed the evaluation by finite elements of prototypes of dental implants with different external geometric shapes submitted to different conditions of loading (axial, inclined to 15° and inclined to 30°).
Results: The stress increased as the loading became more inclined. The conical geometry showed itself more stable and transmitted less stress to the bone. Conclusions: I) The system with conical dental implant transmits lower stress to the bone and to the dental implant; II) the safety factor of the implants is high suggesting it supports loadings more aggressive in intensity and direction; III) as the loading becomes more inclined, i.e., the components of the lateral forces increase, the stresses on the bone and on the prosthetic components increase; IV) for all simulations, the systems behaved appropriately so there is no indication of deformation or fracture on the prosthetic components or even bone resorption due to overload.
