What is the most crucial factor for the incorporation and healing of non-vascularized autogenous bone graft?

• A. Bone surface area
• B. Cortical to cancellous bone ratio
• C. Graft thickness
• D. Implementation technique

Answer: (B)

The most crucial factor for the incorporation and healing of non-vascularized autogenous bone graft is the cortical to cancellous bone ratio. When grafts are harvested, the ratio of cortical to cancellous bone influences the graft's biological activity and its ability to integrate with host bone. Cortical bone is denser and provides structural stability, but it has less intrinsic healing capacity compared to cancellous bone, which is more vascularized and promotes osteoconduction and osteoinduction. In non-vascularized grafts, the healing process largely depending on the surrounding host bone’s ability to revascularize and provide a suitable environment for bone regeneration. Cancellous bone tends to be more effective for this purpose because it has a higher surface area relative to its volume, which facilitates faster incorporation. Hence, a favorable ratio of cancellous to cortical bone can enhance the graft's overall biological response, favoring healing and incorporation into the recipient site. While other factors such as graft thickness, bone surface area, and implementation technique are relevant to the success of the graft, they do not exert the same level of influence on the biological incorporation process when non-vascularized bone grafts are used. The fundamental interaction of graft tissue with the surrounding biological environment is primarily
