Outline of Final Research Achievements

The purpose of this study is to development new bioabsorbed mesh onplant system for orthodontic anchorage. Firstly, we prepared a full-thickness osteochondral defect in the patellar fossa of rabbits, added a bisphosphonate (BPs) preparation to bovine tooth-derived Demineralized Dentin Matrix (DDM), which has its own osteochondral repair ability, and investigated osteochondral repair ability in the defects. As a result, we suggested that the addition of high-dose BPs inhibits the osteochondral repair ability of DDM.　Secondly, the study was to identify the effect of Reveromycin A (RMA) on inhibiting bone resorption in OPG KO mice. Moreover, RMA reduce alveolar bone loss in OPG KO mice.
These data suggested that two unique agents for inhibiting osteoclast activity might increase the bone formation on bioabsorbed mesh onplant system.
