초록
Bone graft has been used to repair one defect caused by disease and trauma, congenital and acquired deformities. Graft materials are autogenous bone, allogenic bone, xenogenic bone, synthetics. Autogenous bone graft is the most superior to other materials for immunologic reaction, compatibility to host tissue, and revascularization. However, autogenous bone graft is required for additional operation and the amount of taking is limited. Autografts are obtained at own expense and also limited in size, shape. In order to compensate these problems, allogenic bone graft has been used increasingly. But allogenic bone graft encounters immunologic complications. Therefore, it has been used after freezing, lyophilization, or demineralization. Allogenic bone processed by only lyophilization includes potential antigenic properties on its surface, therefore it is demineralized to deplete immunologic reaction. Demineralized bone releases BMP and helps the mesenchymal cells transform to the chondroblast to produce cartilage and bone. This reaction is called osteoinducation. Many authors have reported that mineralized lyophilized bone had less antigenicity clinically and favorable bony consideration with host bone. In our department from 1995 to now, we have used banked allogenic bone graft that has been prepared from Wonkwang Bone Bank in 5 cases and mineralized lyophilized bone graft in 2 cases to reconstruct the maxillofacial bone defect after tumor resection and cyst enucleation and cleft alveolus. We will report with literature review that the result is favorable functionally and esthetically.
