Cancellous bone grafts are considered to have the greatest osteogenetic potential due to their high content of viable osteoprogenitor cells, which are essential for new bone formation. These grafts are typically harvested from the iliac crest or other areas rich in cancellous bone. The porous and vascular nature of cancellous bone facilitates the infiltration of host blood vessels, promoting the integration of the graft and enhancing the healing process.

This method not only serves as a scaffold for new bone growth but also contains an abundance of growth factors and immature bone cells, which are crucial for osteogenesis. The presence of these factors in cancellous bone grafts significantly contributes to new bone formation, making them a preferred choice in situations requiring strong osteogenic potential, such as in various orthopedic and dental procedures.

In contrast, other methods like freeze-dried bone grafts may lack viable cells, relying instead on the graft's structural integrity and biological characteristics. Marrow grafts are beneficial for their hematopoietic and mesenchymal stem cell content but may not match the robust osteogenic potential of cancellous bone. Lymphocytic bone grafts are not commonly utilized in standard bone grafting procedures and do not provide the necessary properties for bone regeneration like cancell
