| Research Abstract |
Investigation into the cause of bone resorption after dental implant placement was attempted from the viewpoint of strength of material. Visualization of the strain distributions of mandibular bone model around a dental implant was realized, and quantitative evaluation of the strain distributions under simulated dental occlusion was conducted. Mechanical circumstances of mandibular bone in immediate-loading implantology were more severe than the ones in osseointegration implantol-ogy. The results suggest that immediate-loading implantology which is recently noticed for shortening the treatment period is subjected to bone resorption compared to osseointegration implantology which is the traditional implant method if the dental occlusion force is overloaded.
