In osteoinduction, the graft actively stimulates the resident osteoclasts and  Graft Osteoconduction: The facilitation of a bone healing process into a defined However, bone marrow aspirate applied to osteoconductive scaffolds are still  Provide an overview of the methods of bone grafting, as well as be able to distinguish their different osteoconductive properties and their composition. Understand  Types of Bone Grafts. • Autograft. • Allograft. • Bone graft substitutes.

Osteoconductive materials do not induce healing better than transfer of the patient’s own bone. The combination of both osteoconductive and osteoinductive properties similar to that found in autografts can further promote fusion beyond what an osteoconductive scaffold can produce alone.

Surface characterization of bone graft substitute materials

Although all bone grafts are osteoconductive to bone-forming osteoblasts, only a small number of commercially available bone grafts with FDA approval are osteoinductive including demineralized freeze-dried bone allographs (DFDBA) and scaffolds containing bone morphogenetic proteins (BMPs). Osteoconduction means that bone grows on a surface. This phenomenon is regularly seen in the case of bone implants. Implant materials of low biocompatibility such as copper, silver and bone cement shows little or no osteoconduction.

Osteoconductive graft

Osteogenesis is the process of development and formation of bone. Osteoconduction is the ability of bone-forming cells in the grafting area to move across a scaffold and slowly replace it … Currently used bone graft substitutes that primarily offer osteoconductive properties include coralline hydroxyapatite, collagen-based matrices, calcium phosphate, calcium sulfate, and tricalcium phosphate. These products vary considerably in chemical composition, structural strength, and resorption or remodeling rates. The use of this synthetic osteoconductive bone graft substitute with zeta potential control may have positive effect on the controlled sliding of the helical blade and the healing of intertrochanteric fracture.

Osteoinductivity for CaP bone grafts substitutes does occur although it is a bio-product associated with using these materials as an osteoconductive graft.
