摘要：
PURPOSE: A method for manufacturing artificial bone and artificial bone manufactured thereby are provided to apply artificial bone to finger bone or toe bone. CONSTITUTION: A method for manufacturing artificial bone is as follows. Polymethylmethacrylate and polycaprolactone are dissolved in nitromethane and acetone(S2a). The mixture solution of polymethylmethacrylate and polycaprolactone solution is mixed with hydroxy-apatite powder(S2b). Polymethylmethacrylate/polycaprolactone/hydroxyapatite mixture fiber is produced by applying voltage to the mixture solution of polymethylmethacrylate/polycaprolactone/hydroxyapatite solution mixed withe hydroxy-apatite powder(S2c). The mixture fiber of the polymethylmethacrylate/polycaprolactone/hydroxyapatite is reeled on a wire(S2d). [Reference numerals] (AA) Completion； (BB) Mixing HAp powder； (CC) Producing PMMA/PCL/HAP fiber； (S2a) Dissolving PMMA and PCL in nitromethane and acetone； (S2b) Dipping polyurethane sponge in zirconia slurry； (S2d) Reeling PMMA/PCL/HAP fiber on a wire본 발명은 인공골의 제조방법 및 이에 의해 제조된 인공골에 관한 것이다.본 발명은 해면골을 모방하기 위해 폴리우레탄 스폰지를 이용한 지르코니아와 비페이직 칼슘 포스페이트의 지지체를 제조하고, 치밀골을 모방하기 위해 전기방사에 의해 생성된 섬유를 철사에 감싸서 하버시안 구조를 모방하고, 이렇게 섬유가 감싸진 섬유를 다발로 구성한 후 섬유를 다시 감싸서 오스테인 구조를 모방함으로써 천연골의 해면골 및 치밀골을 제조할 수 있다.
