The aim of this study is to analyze the stress distribution on splinted implant-supported prostheses varying prosthetic connection and implant angulation by means of the three-dimensional nonlinear finite element method. 18 three-dimensional models will be fabricated using the graphical modeling softwares SolidWorks 2010, Rhinoceros 4.0 and InVesalius. Each model will be composed by a bone block from the maxillary molar region (cortical and cancellous bone) Type IV and three dental implants (Conexão Sistemas de Prótese Ltda., Sao Paulo, Brazil), external-hexagon or morse taper implant (4.0 mm) of different lengths (8.5 mm and 10.00 mm), with metal-ceramic crown and 20º cusp inclination. The three-dimensional designs will be exported to the pre and post processing software, FEMAP 10.2, for mesh generation and application of an axial (200N) and oblique (100N) load, then, the analysis will be performed by the finite element software, NEiNastran 9.2. The results will be visualized through von Mises stress and Maximum Principal Stress maps in each individual model proposed.
