Zusammenfassung: | PURPOSE: A bioabsorbable type bioactive glass-ceramic and a preparation method thereof are provided to control the biodegradable speed according to the formulation ratio of glass-ceramics while maintaining the bioactivity. CONSTITUTION: The bioabsorbable type bioactive glass-ceramic comprises 41.4 to 45.75 wt.% of CaO, 35.0 to 47.62 wt.% of SiO2, 1.62 to 14.58 wt.% of P2O5, 0.5 to 14.58 wt.% of B2O3, 0.46 to 4.14 wt.% of MgO, and 0.05 to 0.45 wt.% of CaF2. The bioabsorbable type bioactive glass-ceramic is composed of the first glass and the second glass in a weight ratio of 90:10 to 10:90. The first glass comprises 41.03 to 45.86 wt.% of CaO, 43.97 to 49.14 wt.% of SiO2, and 5 to 15 wt.% of B2O3. The second glass comprises 44.7 wt.% of CaO, 44.7 wt.% of MgO, 34.0 wt.% of SiO2, 16.2 wt.% of P2O5, and 0.5 wt.% of CaF2.
본 발명은 생분해 속도가 늦은 결정화 유리와 생분해 속도가 빠른 결정화 유리를 복합 조성함으로써 생체 활성을 유지하면서 생체 분해 속도가 복합 비율에 따라 조절되는 결정화 유리에 관한 것이다. 본 발명은 산화칼슘(CaO), 실리카(SiO), 산화붕소(BO), 산화마그네슘(MgO), 불화칼슘(CaF), 오산화인(PO)으로 조성된 것을 특징으로 하는 생체 흡수형 생체 활성 결정화 유리를 제공한다. |
