Краткое описание

The aim of this study was relative variation quantification of the total electric field (EF) sum in a region very close to a dental root of the first molar tooth for two different materials: dentine (before implantation) and titanium (present in a screw after implantation), due to development of electrical charges generated by chewing force on the tooth. Because bone is a piezoelectric material, mechanical strain that is generated by chewing force on bone adjacent to the dental root produces electrical charges. Relative variations in the EF sum values with distance of nodes from the centerline of the root was observed for both cases and studied for two different boundary voltage conditions. Simulation and analysis were performed using the commercial finite-element analysis package ANSYS14. The detailed convergence analysis validated the effectiveness and accuracy of finite-element simulations. Before and after implantation, a significant variation in generation of electric charges at adjacent bone of the dental root was observed. We found that the differences in stress generation at the adjacent bone for those cases were just 5%, on average.
