The demand of bone graft materials has been increasing. Among various origins of bone graft materials, natural coral composed of up to 99% calcium carbonate was chosen and converted into hydroxyapatite (HA); silicon was then substituted into the HA. Then, the Si-HA was mixed with β-tricalcium phosphate (TCP) in the ratios 100:0 (S100T0), 70:30 (S70T30), 60:40 (S60T40), and 50:50 (S50T50). The materials were implanted for four and eight weeks in a rat calvarial bone defect model (8 mm). The MBCPTM (HA:β-TCP = 60:40, Biomatalante, Vigneux de Bretagne, France) was used as a control. After euthanasia, the bone tissue was analyzed by making histological slides. From the results, S60T40 showed the fastest bone regeneration in four weeks (p < 0.05). In addition, S60T40, S50T50, and MBCPTM showed significant new bone formation in eight weeks (p < 0.05). In conclusion, Si-HA/TCP showed potential as a bone graft material.
骨移植材料的需求一直在增加。在各种骨移植材料来源中,选择了碳酸钙含量高达99%的天然珊瑚并将其转化为羟基磷灰石(HA);然后将硅取代到HA中。接着,将硅-羟基磷灰石(Si-HA)与β-磷酸三钙(TCP)按100:0(S100T0)、70:30(S70T30)、60:40(S60T40)和50:50(S50T50)的比例混合。将这些材料植入大鼠颅骨骨缺损模型(8毫米)中4周和8周。使用MBCPTM(HA:β-TCP = 60:40,Biomatalante,法国布列塔尼维格涅)作为对照。安乐死后,通过制作组织学切片对骨组织进行分析。结果显示,S60T40在4周时骨再生最快(p < 0.05)。此外,S60T40、S50T50和MBCPTM在8周时显示出显著的新骨形成(p < 0.05)。总之,Si-HA/TCP作为骨移植材料具有潜力。
