The aim of this study will be to evaluate the stress distribution generated by the splinted implant-supported prosthesis varying the implants location, pontic and cantiliver configuration, using the finite element method. For this study will be simulated 6 3-D model with aid of CAD softwares Rhinoceros 4.0 and Solidworks 2010 besides InVesalius software that will be used to bone tissue reconstruction. Each model will represent a posterior maxillary bone section simulating type IV bone (cortical and spongy), with presence of 2 or 3 implants (Conexão Sistemas de Prótese Ltda., São Paulo, Brasil) external hexagonal implants, with 4,0mm x 10,00mm, supporting 3-units prosthesis, being: Model 1 - Aligned implants supporting single crowns; model 2 - aligned implants supporting 3-unit splinted prosthesis; model 3 - implant tripod alignment supporting 3-unit splinted prothesis; model 4 - 3-unit splinted prosthesis central pontic; model 5 - 3-unit splinted prosthesis mesial cantilever; model 6 - 3-unit splinted prosthesis distal cantilever. The 3D models will be exported to the software FEMAP 10.2 for pre- and post- processing and mesh generation besides load definition (200N vertical and 100 N oblique (45°)) applied in the internal area of the crown cusp. After, the models will solved by NeiNastran 9.0 finite element software and the results will be visualized by Von Mises stress and maximum principal stress maps individualized as required and necessary for each proposed model.
