Abstract
The interest in autogenous demineralized dentin matrix (ADDM) graft has been growing in dentistry, however, it was considered that ADDM graft was impossible immediately after extraction because the process of making ADDM is time-consuming. Therefore Authors had studied about the methods of making ADDM graft material immediately after extractiton. The aim of this study is to evaluate the effectiveness and stability of immediate post-extraction ADDM graft by presenting the case reports. In a 20-year-old female patient, bone augmentation using autogenous bone and ADDM which was demineralized by 2% HNO3 for 20 minutes was done immediately after third molars extraction, because of lack of the remaining bone width for implantation on #12,13. After 4 months, implantation and bone biopsy were done. Bone quality was hard clinically. In histologic examination, new bone formation was observed around grafted ADDM without inflammation. This result has showed that ADDM which was demineralized by 2% HNO3 immediately after the tooth extraction is acceptable bone graft material. ADDM has ability of osteoinduction. Further long term evaluation via prospectively designed studies are needed.
