1. Increase mechanical support and structural stability: Artificial bone has good mechanical properties and can provide additional support and stability for the transplantation site. Mixing artificial bone and autogenous bone can combine their advantages and increase the mechanical strength and stability of the transplanted site.

2. Expand the range of available bone sources: Autologous bone transplantation needs to extract bone tissue from patients themselves, but sometimes the quality of autologous bone or the amount of autologous bone that can be extracted from patients is insufficient. Mixed use of artificial bone can expand the range of available bone sources and alleviate the problem of insufficient supply of autologous bone.

3. Reduce surgical trauma: Autologous bone transplantation requires additional surgical steps and incisions, which may increase the risk of surgical trauma and complications. Mixed use of artificial bone can reduce the dependence on autologous bone, thus reducing surgical trauma and surgical risk.
