This study aimed to verify and compare these stresses in prosthetic infrastructures according to the variation in the material used to make them. The von Mises Equivalent Stresses (VMES) were qualitatively and quantitatively analyzed in the most significant stress areas in these infrastructures, which were divided into different experimental groups: Cobalt-Chrome (CoCr); Nickel-Chromium (NiCr); Titanium (Ti); Zirconia (Zr); Lithium disilicate (LD); Type IV gold (Au) and Acrylic resin (AR). They were then analyzed using the Finite Element Method (FEM) to verify the stresses developed, as well as their intensity and scope, using a color scale generated in a virtual computer analysis environment (Ansys Workbench Software). The results allowed us to observe that different stresses are generated in the material used in the prosthetic infrastructure, depending on its variation. A directly proportional relationship was found between the stiffness of the material and the stresses generated, meaning that greater rigidity results in greater stresses.
