A numerical study for the variation of cortical bone thickness with several dental implants

Abstract

Dental implant is increasingly used to recover the mastication function of tooth. Several types of implant were designed to give an optimal stress distribution in bony regions. In this study, six types of implant were investigated using finite element method and it was studied i) how the variation of cortical bone thickness affects the stress distribution in bony regions depending upon implant types, ii) which types gives the best characteristics in the sense of stress distribution and stability. The hybrid-type implant which cylinder and screw gave the optimum properties in view of stability and response due to variation of cortical bone thickness.
