A New Interactive 3-D Numerical Model of the Human Mandible for Peri-Implant Analysis in-Vivo Compared With Cone Beam Computed Tomography 3-D Quality

Abstract

Dental implants have been widely and increasingly used in the past few decades to support and retain partial and complete dental prosthesis. The fear of failure due to mechanical overloading increased the need for stress-strain analysis along bone-implant interface of the ever growing designs of dental implants. Finite element analysis (FEA) was used by many authors to evaluate stresses around dental implants and to predict their survivability, where to extract a robust FEA model a realistic information system must be used. In this study an interactive 3-D model was retrieved from Computed Tomography (CT) images utilizing, a proposed software are used to obtain high image quality of the jaw bones scanned by 3-D CT compared with Cone Beam Computed tomography (CBCT) output. Identification of different anatomical regions set for mandible cortical and spongy bones with soft tissues by generated 3-D models and validated with real measurements from solid model.
