Outline of Final Research Achievements	Bone resorption of 1 to 1.5 mm occurs in the first year when occlusal force is applied to the implant."Microgaps" that exist between implant and abutment is attracting attention as one factor that affects bone resorption. It is said that bone resorption is induced by leakage of bacteria and inflammatory substances from the microgap as stress is applied to the prosthetic device and the microgap is released. In this study, we evaluated the difference in the leakage amount of the bacteria from the microgap in implants with different connection types.
