【摘要】：分别采用液相和气相发泡法制备了可注射的多孔硼酸盐生物玻璃基骨水泥(BBGC)。比较了2种发泡方法对骨水泥注射性、抗压强度、孔隙率、抗溃散性和降解性能的影响。研究表明:2种发泡方法制备的BBGC均具有优异的注射性能,注射率达90%。但液相发泡法制备的BBGC样品抗压强度可达(4.28±1.05)MPa,在抗压强度和抗溃散性方面优于气相发泡法。气相发泡法制备的BBGC的开口孔隙率达40%,高于液相发泡法的27%。浸泡产物的X射线衍射和红外光谱分析表明:2种发泡方法制备的BBGC均能矿化生成羟基磷灰石Ca_(10)(PO_4)_6(OH)_2,但是气相发泡法制备的BBGC的矿化性能优于液相发泡法。
[Abstract]:The injectable porous borate biological glass-based bone cement (BBGCN) was prepared by liquid-phase and gas-phase foaming methods respectively. The injectability, compressive strength and porosity of bone cement by two kinds of foaming methods were compared. The results showed that BBGC prepared by two kinds of foaming methods had excellent injection performance. However, the compressive strength of the BBGC samples prepared by the liquid phase foaming method was 4.28 卤1.05 mpa, which was superior to that of the gas-phase foaming method in terms of compressive strength and collapsibility. The opening porosity of the BBGC prepared by the gas-phase foaming method was 40%, which was higher than that of the liquid-phase foaming method (27%). X-ray diffraction (XRD) and infrared spectroscopy (IR) analysis of the soaking products show that the BBGC prepared by the two kinds of foaming methods can mineralize to form hydroxyapatite CaS10 / P _ 4 / T _ 6 / O _ H _ 2, but the BBGC prepared by the gas-phase foaming method is superior to the liquid-phase foaming method.
