Desenvolvimento e analise estrutural de prótese de Scaffolds para reconstrução mandibular

Abstract

Mandibular reconstruction has been a challenge for maxillofacials, despite significant advances in medical technology. New types of implants present a new direction in the evolution of mandibular restoration. The design and properties of implants for mandibular reconstruction should be able to recover the anatomy and contour of the lost region, as well as restore functions, including mastication and esthetics. The present work aims to develop and analyze a Scaffold prosthesis for mandibular reconstruction. Using computed tomography for data acquisition, which were converted into 3D files, for the development of the implant, the customized prosthesis was evaluated regarding its functional and aesthetic aspects. The project proved to be effective when subjected to forces that resulted in stresses applying the von Mises criteria that did not extrapolate the yield limit of the material applied in the reconstruction, with the following stresses being obtained 250 MPa, 320 MPa and 658 MPa, applying respectively 250 N, 500 N and 1000 N. Thus, it can be concluded that, by the process presented, it is feasible to elaborate the customized implant.
