The present invention relates to an HA/PLGA composite bone restorative material in which calcium phosphate is incorporated into PLGA using PLGA as a biodegradable polymer and, more specifically, to a production method of an injectable calcium phosphate-PLGA composite bone restorative material, where calcium phosphate is gradually released as PLGA is decomposed, so that a bone formation effect is maintained for a long time.COPYRIGHT KIPO 2017본 발명은 생분해성 고분자의 일종인 PLGA를 사용하여 인산칼슘이 PLGA 내에 함입된 HA/PLGA 복합 뼈수복재로, PLGA가 분해되면서 인산칼슘이 서서히 방출되므로 뼈 형성 효과가 장시간 지속되는 주입형 인산칼슘-PLGA 복합 뼈수복재의 제조방법에 관한 것이다.
