D. Osteointegration – bonding of the host and the graft material, resulting in new bone present in the graft

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
