Bone Allograft - an overview ScienceDirect Topics

Bone graft extenders are a form of allografts that are used as viable substitutes, with the most common being demineralized bone matrix (DBM). 3,16–18 DBM is prepared via an elaborate process involving harvesting and cleaning of cortical bone that is subsequently ground and demineralized through acid extraction, generating a noncollagenous ...

Evaluation of bone allograft processing methods: Impact on ...

Jun 20, 2019  In an ever-aging society the demand for bone-defect filling grafts continues to gain in importance. While autologous grafting still prevails as the gold standard, allografts and xenografts present viable alternatives with promising results. Physiochemical properties of a graft strongly depend on the processing method such as the decellularization protocol.
