摘要
本文将自制的以氟磷灰石和镁白云母为主晶相的新型微晶玻璃人工骨材料,植入动物骨中112天后。发现这种材料与骨产生了牢固的化学结合。用扫描电镜、X射线能谱和电子探针分析了这种材料与骨结合界面层的生物活性结构,并提出了一个新的结构模型来解释该材料产生生物活性的物理化学变化过程。
A new type of glass-ceramics for bone substitution has been developed. The material contains fluorapatite and Mgmuscovite as two main crystal phases, and is therefore bioactive and machinable. A stable chemical bond between the material and the bone of the animal was formed 112 days after inserting the material into the bone.The bioactive structure of theinterface layer was analyzed with scanning electron microscope, energy dispersive X-ray spot analysis and electron probe, and a new structure model was proposed, to explain the physico-chemical process from which the material obtained bioactivity.
