Safety and efficacy of commercially available demineralised bone matrix preparations: A critical review of clinical studies

Dernineralised bone matrix (DBM), a form of allograft, possesses the properties of osteoinductivity and osteoconductivity. A large body of data obtained from extensive preclinicat studies have clearly supported the utility of DBM in human clinical settings. However, it is now recognized that various DBM configurations may differ considerably with regard to their bone inductive activity. Several factors could account for such variability, including the biologic properties of the graft, the host environment, and the methods of allograft preparation. The differing efficacy of DBM products may also depend on differences in particle size and shape, donor selection criteria, protocols for collection and storage, as well as DBM carrier materials. Several comparative studies have confirmed the differences in the osteoinductive potential of various DBM preparations. The purpose of the present review is to provide a critical overview of the current applications of DBM in a clinical setting. (C) 2007 Elsevier Ltd. All rights reserved
