NCIt definition : Demineralized allograft bone with osteoinductive activity. Demineralized bone matrices
are prepared by acid extraction of allograft bone, resulting in loss of most of the
mineralized component but retention of collagen and noncollagenous proteins, including
growth factors. The efficacy of a demineralized bone matrix (DBM) as a bone-graft
substitute or extender may be related to the total amount of bone morphogenetic protein
(BMP) present, and the ratios of the different BMPs present. BMPs belong to the transforming
growth factor (TGF) superfamily of proteins.;
