Abstract

In order to understand the problems, which occur during the implanting and the prosthetics process, it was highly important to be acquainted with the anatomy of the human skeleton, the way these components are working together to achieve a normal functionality. In this respect CAD parametric software has been used as it allows to define models with a high degree of difficulty. First, the main bone components were defined by using CT images. These images were then transferred to AutoCAD where the outer and inner contours of the bone were approximate to polygonal lines composed by many segments. These contours were transferred to SolidWorks where, step by step, and section by section, the virtual model of the chewing system has been defined. Using the direct measurement method the virtual metallic components used during implant process were generated. The virtual models were then exported to a software for kinematical and FEA simulation. Using similar initial parameters for each case studied (as total force and torque) there were obtained dynamic maps of stress, strain and displacement. Furhermore the results have been analyzed and compared, leading subsequently to the main extracted conclusions
