Purpose: to analyze and compare the stresses in finite elements of a proposed triangular conical connection in implants, with hexagonal and conical connections. Materials and methods: the solidworks 2017 ® software was used for finite element analysis, a premolar crown on implants (3.8x12mm) with external and internal hexagon, morse cone, conical connection and the new triangular conical proposal were considered. Forces of 150N, 250N and 350N were applied to the premolar. The implants were analyzed using the von Mises stress criterion. Results: At the implant, abutment and crown level, the maximum compressive stress was found in the external hexagon connection. At the level of the abutment with forces of 350N, the lowest tension occurred in the new proposal and the conical (10Mpa). Conclusions: in the 5 designs the maximum stress is concentrated at the level of the neck of the abutment, implant and bone, except for the morse cone. The new triangular conical connection proposal obtained the second lowest stress in the implant; in the bone the stress was less than 0.8Mpa. This suggests that it may be an option that generates less stress in the bone, adding an advantage of having three retention points.
