dental implants, finite element analysis, fixed partial denture, infrastructure


The configuration of fixed partial dentures with a suspended or pontic intermediate element, associated with the use of 2 implants at their ends, is usually found clinically. In a situation with a smaller number of implants supporting an eventual 3-element prosthesis, there is a greater biomechanical demand on the entire system. A possible option to reduce the stresses disseminated to the implants and components is to vary the prosthesis infrastructures. Therefore, the objective of this study was to verify and compare the stresses developed on the implants and components according to the variation of the materials of the infrastructures of the prostheses on implants. The von Mises Equivalent Stresses (VMES) were analyzed for quantitative and qualitative assessment of the areas of greatest biomechanical demand. The experimental groups were varied according to the infrastructure used: Acrylic resin (AR), Lithium disilicate (LD), Type IV gold (Au), Titanium (Ti), Nickel-Chromium (NiCr), Cobalt-Chromium (CoCr) and Zirconia (Zr). The methodology used was the Finite Element Method (FEM), with simulations by the Ansys Workbench 10.0 software program. The results obtained allowed observing that, according to the variation of the material used in the prosthesis, there are different stresses generated in the analyzed ductile structures (implants and components). It can generally be concluded that an inversely proportional relationship was found between the stiffness of the infrastructure material and the stresses generated in the implants and components. Thus, more rigid infrastructures are capable of transmitting less stress to the implants and their components, which would be characterized as the best option in order to preserve the implants and components that are closer to the supporting bone.
