Abstract

This project aims to analyze the stress on implant-supported fixed prostheses over morse taper implants, single unit and splinted prostheses, in the posterior region of the maxilla varying the length of the implants, and prosthetic fixation, by use of three-dimensional nonlinear finite element method. 12 three-dimensional models will be simulated with the assistance of CAD programs Rhinoceros 3D 4.0 (NURBS Modeling for Windows, USA) and SolidWorks 2011 (SolidWorks Corp, USA). The bone portion will be obtained by use of InVesalius (CTI, São Paulo, Brasil). Each model will represent a section of bone of the maxillary posterior region in the form of a type III bone block (cortical and trabecular), with the presence of 3 morse type implants with 4,0mm in diameter and different lenghts (7,0mm, 8,5mm, 10mm, 11,5mm) 1mm below the cortical bone supporting prosthesis of 3 elements with metal-ceramic crowns. The three-dimensional models will be exported to the pre and post processing program FEMAP v.11.0 (Siemens Product Lifecycle Management Software Inc. USA) for mesh generation and configuration of load of 400N axial and 200N oblique (45º) applied at each dental cusp. The analysis will be performad by NEiNastran 11 (Noran Engineering, Inc., EUA) and results will be displayed using von Mises tension maps and maximum principal stress tension maps that will be individualized for each proposed model as necessary.
