Abstract
The objective of present study is to determine the effect of the tilted angle of dental implants supporting the maxillofacial prosthesis on the stress and strain distribution of the dental implants, abutments and bone. Present authors already determined the stress and strain distribution of the abutment and the superstructure body supported by three implants. In this study, the material properties of bone and titanium were substituted to the 3 dimensional finite element method (3DFEM), then the stress and strain were analyzed. We subsequently discussed the better implant alignment. Finally, a human-friendly implant and a superstructure body having longer life than usual were designed. The result suggested that tilted implants should be designed their tips separating each other like a root of plant.
