Which is the most common osteoinductive material used for bone grafting?

Autogenous grafts, also known as autografts, are considered the most common osteoinductive material used for bone grafting because they are derived from the patient's own body. This eliminates the risk of immune rejection and disease transmission, as the graft's biological properties and the presence of growth factors stimulate new bone formation effectively. Autogenous grafts contain vital osteoprogenitor cells, which are essential for the regeneration of bone, clearly making them the gold standard for osteoinduction in bone grafting procedures.

The other materials, while offering various advantages, do not match the intrinsic benefits of autogenous grafts. For instance, allografts come from other individuals and can carry a risk of immune response or disease transmission, although they are widely used due to their availability. Xenografts, sourced from different species, can provide structural support but generally lack the osteoinductive properties seen in autogenous grafts. Synthetic biomaterials can be designed to support bone regeneration, but they often do not possess the same biological mechanisms for inducing bone formation as autografts do. Therefore, autogenous grafts are recognized as the most effective in promoting new bone growth due to their comprehensive biological compatibility and osteoinductive capabilities.
