Demineralized allografts (, Grafton TM, Magnifuse TM DBMs), on the other hand, have been processed in a manner that strips the natural mineral component away from the bone to expose native growth proteins. The native proteins exposed during the demineralization process produce a signal to the body to recruit bone forming cells to that area and form new bone.
