Osteogenesis is the formation of new bone by cells found within the graft.
Osteoinduction is a chemical process by which molecules, such as bone morphogenic protein, in the graft convert neighboring cells into bone-producing osteoblasts.
Osteoconductive grafts have no biological influence on surrounding tissues, they form a scaffold onto which migrating cells can form new bone
