Abstract
- Dental implant is increasingly used to rehabilitate the masticatory function of missing teeth. Several types of dental implant have been designed to give an optimal stress distribution to the surrounding bone, In this study, six typer of implant were investigated using finite element methods 1)how the variation of cortical bone thickness affects the stress distribution in bony regions depending upon implant types, and 2) which type gives the best characteristics in the sense of stress distribution and stability. The hybrid-type implant with tapered cylinder and screw gave the optimum properties in view of stability and response due to variation of cortical bone thickness.
