Abstract

본 발명은 생체 흡수성 친수성 재료로 이루어지는 다공성 구조체의 표면에 생체 흡수성 고분자 재료로 이루어지는 표면층을 갖는 복합 다공질체에, 골 유도인자를 함유하는 것을 특징으로 하는 골 형성용 이식체에 관한 것이다. 바람직하게, 생체 흡수성 친수성 재료는 젤라틴, 히알루론산, 히알루론산 유도체, 콜라겐, 콜라겐 유도체, 키토산, 키토산 유도체 및 트리에탄올아민 알기네이트로 이루어지는 그룹에서 선택되는 1종 이상의 화합물을 포함하며, 생체 흡수성 고분자 재료는 폴리락트산, 폴리락트산 폴리글리콜산 공중합체 및 폴리〔비스b-카복시페녹시)프로판〕무수물과 세바신산과의 공중합체로 이루어지는 그룹에서 선택되는 1종 이상의 화합물을 포함한다. 본 발명의 골 형성용 이식체는 성형성 ·조적성에 있어 우수하고, 생체내 골 신현성에 적하한 내부 구조를 지니기 때문에, 골 이식은 이식체의 주변부 뿐만 아니라 이식체의 내부에서도 일어난다.
