Definitions
- the present invention relates to a bone repair material having an effect of enhancing the bond between natural bone and a bone repair material * artificial bone, and a human bone composition.
- Bone transplant is the most frequent type of tissue transplant. Clinically, it is performed after bone loss due to trauma, prolonged healing of fractures, or removal of pseudoarthrosis or bone tumor.
- autogenous bone grafting using a patient's own bone has been widely used as a bone grafting procedure in a living body.However, the amount of autogenous bone used for autogenous bone grafting is limited. It requires two operations, collection and transplantation, which hurts the patient.
- Artificial bones such as metals and ceramics have been developed and used to compensate for the drawbacks of autologous bone transplantation. The role of the implanted bone is to promote osteogenesis and to obtain mechanical support. When artificial bone is used, mechanical support is sufficient, but promotion of osteogenesis cannot be expected.
