Graft type with osteogenic, osteoinductive, and osteoconductive properties?

Graft type with osteogenic, osteoinductive, and osteoconductive properties?

• A. Allograft bone
• B. Autograft bone
• C. Demineralized bone matrix
• D. Synthetic bone graft

Answer: (B)

Osteogenic, osteoinductive, and osteoconductive properties describe three ways a bone graft can support new bone formation. Osteogenesis comes from living cells in the graft that can form bone, osteoinduction comes from growth factors that recruit and stimulate progenitor cells to become osteoblasts, and osteoconduction provides a physical scaffold for new bone to grow into. Autograft bone uniquely delivers all three: it contains viable osteogenic cells, inherent growth factors, and a natural scaffold, with the added benefit of no disease transmission or immune rejection. That combination makes autograft the best option when the goal is reliable, rapid fusion. Other grafts may supply one or two of these properties but not all three: allograft bone has limited viable cells after processing; demineralized bone matrix offers strong osteoinduction but typically lacks living osteogenic cells; synthetic grafts provide a scaffold (osteoconduction) but no native cells or growth factors unless supplemented.
