| Outline of Final Research Achievements |
Effects of titanium granules in the peri-implant bone loss was examined in the present research. First, we overviewed the current scientific knowledge and evaluated the quality of reports. As a result, there was no clinical evidence discussing the influence of titanium granules. In addition, it was shown that the quality of reporting by systematic review on peri-implant inflammation is low. Next, in the rat maxilla, titanium granules were scattered around the implant-abutment interface, and the change of the surrounding bone was analyzed assuming the same situation as the wear occurred. As a result, it was shown that the effect of titanium granules causes peri - implant bone resorption. Though we tried to analyze the mechanism using cultured cells, but we could not obtain the result indicating this.
