DBM contains bone morphogenetic proteins (BMPs), which induce and regulate bone formation during embryogenesis and in postnatal life. AIMS AND OBJECTIVES: To investigate the osteoinductivity of DBM augmented with xenogeneic BMP-complex at different doses. MATERIALS AND METHODS: Rat DBM was augmented with BMP-complex purified from porcine diaphyseal bone. RESULTS: Dorsal subcutaneous implantation of 25 mg rat allogeneic DBM augmented with 0, 3, 6 and 12 mg BMPcomplex per gram of DBM resulted in dose dependant upregulation of bone formation on day 21, as scored histologically and biochemically. CONCLUSIONS: Allogeneic DBM can be augmented with xenogeneically sourced BMP-complex to improve DBM performance in vivo. This work demonstrates the potential of BMP-complex augmented DBM to induce new bone formation with improved parameters of bone formation.enSouth African Dental AssociationBone regenerationDemineralised bone matrixBone morphogenetic proteinsBone graft substituteOsteoinductionBone-grafting -- ResearchArticle
