【摘要】 利用具有自固化性能的医用硫酸钙(CSH)与具有骨诱导性的生物活性玻璃(BGs)制备了新型的骨修复复合材料CSH/BGs。详细研究了CSH/BGs的力学性能和自固化性能。考察了CSH/BGs复合比例、BGs粒径、CSH长径比及固化液用量对CSH/BGs抗压强度及自固化性能的影响。结果表明:增加CSH/BGs中BGs的含量使CSH/BGs的抗压强度降低;BGs粒径对CSH/BGs力学性能影响显著;增加固化液用量能降低CSH/BGs的抗压强度,增长自固化时间。更多还原

【Abstract】 Bone repairing composite materials(CSH/BGs) basing on medical calcium sulfate(CSH) with self-setting property and bioactive glass(BGs) with osteoconductive property were prepared.The effect of the mass ratios of CSH and BGs,the radius of BGs,the length-diameter ratio of CSH and the solidily liquid amount on the compressive strength and self-setting properties of CSH/BGs were investigated.The results showed that with the increase of the content of BGs,the compressive strength of the composites is decreased.Higher ratio of liquid to powder increases the setting time and makes the compressive strength of CSH/BGs decreased.更多还原
