With regard to the design of dental implants based on their geometrical characteristics and their influence on the mechanical behaviour of the implant and the response of the peri-implant bone, many pieces of research dealing with the matter can be found in the bibliography. Based on the observation of the geometrical parameters defined in such studies, one additional parameter was considered: the number of threads. After that, with the use of the Ansys Finite-Element-Analysis Software, three different commercial implants were analyzed and the results were taken as a basis for the proposal of a new design varying the geometrical parameter previously proposed. The result of the simulations show that this additional parameter should be taken into account when defining the geometry of the implant.
