Q

What is osteogenesis?

A

A graph that supplies and supports bone forming cells. Bone formation requires the cellular machinery to fabricate its structural components

30
Q

What is osteoinduction?

A

Materials that have the capacity to induce bone formation when placed into a site where no bone formation will occur these materials recruitment single stem cells or their project infiltrate material of tissues and induce multipotential cells to multiply and become cells that make up regenerating bone Callus
