In the process of repairing of bone defects, bone scaffold materials need to be implanted to restore the corresponding tissue structure at the injury. At present, the repair materials used for bone defects mainly include autogenous bone, allogeneic bone, metal materials, bioceramics, polymer materials and various composite materials. Different materials have demonstrated strong reconstruction ability in bone repair, but the ideal bone implants in the clinic are still yet to be established. Except for autogenous bone, other materials used in bone defect repair are unable to perfectly balance biocompatibility, bone formation, bone conduction and osteoinduction. Combining the latest advances in materials sciences and clinical application, we believe that composite materials supplementedwith Chinese medicine, tissue cells, cytokines, trace elements, etc. and manufactured using advanced technologies such as additive manufacturing technology may have ideal bone repair performance, and may have profound significance in clinical repair of bone defects of special type. This article reviewed to the domestic and foreign literature in recent years, and elaborates the current status of bone defect repair materials in clinical application and basic research in regard to the advantages, clinical options, shortcomings, and how to improve the autogenous bone, allogeneic bone and artificial bone materials, in order to provide a theoretical basis for clinical management of bone defects.
