Which type of graft is most commonly used to obtain bone from the iliac crest?

• A. Endochondral graft
• B. Vascularized graft
• C. Non-vascularized graft
• D. Cellular graft

Answer: (C)

The use of a non-vascularized graft for obtaining bone from the iliac crest is the most common approach in oral and maxillofacial surgery. Non-vascularized bone grafts are typically harvested from sites like the iliac crest because they allow for the procurement of a significant amount of bone while minimizing surgical complications associated with vascularized grafts. Non-vascularized grafts rely on a process called creeping substitution, where the surrounding host bone gradually replaces the grafted bone. This process can be particularly effective in areas where there is adequate blood supply, allowing the graft to integrate over time without the need for its own blood supply. The iliac crest is a favored donor site due to its accessibility and the quality of cortical and cancellous bone available for harvesting. In contrast, vascularized grafts involve the transfer of bone along with its blood supply, typically for more complex reconstructive procedures where blood flow is critical for healing. While vascularized grafts can be beneficial in certain situations, their use is generally less frequent compared to non-vascularized grafts in the context of iliac crest harvesting. Thus, the choice of a non-vascularized graft aligns with the goal of obtaining reliable bone mass for reconstructive needs while facilitating a simpler
