| Research Abstract |
Finite element analysis was performed using a model made from CT image of a person. When young's modulus of the bone prosthetic material was increased, the stress of the filling material was increased, and stress of the peripheral bone was decreased. Further, concentration of strain energy density was presented around the peri-implant bone, the possibility of prediction of bone regeneration state in the peri-implant by the energy density was suggested. The presence of bone prosthetic material reduce the risk of bone loss and promote regeneration of peri-implant bone.
