Osteoconduction is best described as which process?

• A. Osteoinduction via signaling molecules
• B. Direct bone formation by host cells
• C. Providing a scaffold for the growth of new bone
• D. Bone remodeling without a graft

Answer: (C)

Osteoconduction is about providing a scaffold that guides bone growth. It involves a porous, biocompatible structure that serves as a lattice for host bone cells to migrate into and lay down new bone along and through the scaffold. It does not rely on signaling molecules to induce bone formation (that’s osteoinduction), nor on living cells in the graft actively forming bone by themselves (that’s osteogenesis). It also isn’t simply remodeling of bone without a graft. So the best description is providing a scaffold for the growth of new bone.
