Abstract

The aim of this study is to analyze the stress distribution in implant-prosthesis unit using external hexagon and internal morse taper implants in the maxilla anterior region, varying the type of bone support in conventional, bicorticalized and sinus lift , by 3-D finite element analyses. Nine 3-D models will be simulated, using some programs to creating models from CT scans (InVesalius - CTI, Sao Paulo, Brazil) and assisted design programs (Rhinoceros 3D 4.0 - NURBS Modeling for Windows, USA; and SolidWorks 2011 - SolidWorks Corp., USA). The models will be consisted by maxillary bone, with the presence of an implant 4.00 x10mm (Conexão Sistema de Implantes Ltda., Sao Paulo, Brazil), with conventional metal-ceramic crown. The 3D models will be exported to the finite element program FEMAP v.10.2 (Siemens Product Lifecycle Management Software Inc.USA) to determine the regions, mesh generation and finite element analysis in to processing program NEiNastran 10 (Noran Engineering, Inc. ., USA). The total load of 178N is at an angle of 0 º, 30 º and 60 º will be applied. The results will be viewed through von Mises stress and maximum principal tension maps in order to assess the individual variations of the stress distribution in bone, in the implant and in the interface crown /implant.
