Outline of Final Research Achievements

Success of implant treatment is considered to depend on the control of infection and force against the implant. However, the research regarding force control is insufficient and the evidence is required. This research aimed to use the patients’ CT data for diagnosis of implant treatment with 3-D finite element analysis method and clarify the condition which causes absorption of the residual alveolar bone around the implants. The results showed that the design of restoration and the number of implants affects the force against implants. Moreover, the direction of the force against an implant was found to be significant for this influence.
