In the context of bone materials, which is classified as an osteogenic material?

Autogenous bone is classified as an osteogenic material because it contains living cells that can contribute to the formation of new bone. When autogenous bone is harvested from the patient, it provides not only the necessary biological material for grafting but also the osteogenic cells, including osteoblasts, that are crucial for new bone formation. This makes it uniquely effective in promoting bone healing and regeneration.

In contrast, while certain choices like Puros ® allograft and HA alloplast may serve as scaffolds or provide structural support for bone growth, they do not contain living cells that directly form bone. Recombinant BMP-2, although it promotes bone formation by stimulating the activity of osteoprogenitor cells, is not considered an osteogenic material on its own since it lacks the cellular component found in autogenous bone. Thus, autogenous bone stands out as the only material in the context of bone materials that can actively participate in osteogenesis.
