The bone consists of approximately 70% inorganic matter and 30% organic matter. The organic matter surrounded by this inorganic matter contains such growth factors as bone morphogenetic proteins (BMP). Through the demineralization process by which inorganic compounds are removed, growth factors such as BMP, which assist in bone repair, are quickly released and promote osteoinduction, contributing to the quality of bone repair. As a 100% allogenic graft material, it is highly biocompatible.
