Demineralized bone promotes fast and quality bone repair through the osteoinducton of growth factors such as BMP, which are released during the demineralization process. A scaffold is required for the bone cells produced through this osteoinduction to attach. The cancellous bone has a highly porous, three-dimensional form with high strength inside the bone, which creates an ideal environment for revascularization and bone remodeling. This serves as a scaffold to assist in bone repair. Furthermore, as a 100% allogenic bone graft material, it is highly biocompatible.
