| Research Abstract |
RAP induction method: We investigated the treatment method for increasing the activity of osteoclasts (RAP) in local alveolar bone by using a rat maxillary first molars. As a result, we confirmed that it is effective to induce RAP induction when performing osteotomy with the depth reaching bone marrow in both labial and palatal sides at for the total of six portion. (2) LIPUS irradiation conditions: We investigated the irradiation method using ultrasound (LIPUS) irradiation, expecting an increase in osteogenic activity. But we did not yet obtain significant results of changes in formation ability of alveolar bone .
