| Outline of Final Research Achievements |
In this study, delayed and immediate loaded interfaces between bone and implant surface were analyzed comparatively for implant prosthesis designs in edentulous maxilla using continuous structural and non-linear structural approach of finite element analysis.
The results showed that the peri-implant stress value was greater in IL than in DL, and stress concentrated in trabecular bone, considered weaker, in IL. Longer implant, especially, placed bicortically, could decrease stress in bone. Less number of implant for the edentulous maxilla might increase a biomechanical risk, however, 4 to 6 implant prostheses might work almost same in DL.
