摘要
本文对碳/碳化硅(C/SiC)复合材料植入体界面上的生物行为进行了研究。在兔子下颌骨上的植入实验证明,该材料具有良好的生物相容性。EDAX分析发现,在界面的植入体一侧,钙和磷的含量增加,特别是钙的富集比较明显。距界面愈远,增加量愈少。说明在植入以后,体液中的钙和磷向植入体内有扩散作用。
<ABSTRACT>
Light microscopy (LM), X-ray diffraction (XRD), scanning electron
microscopy (SEM) and energy dispersive analyzer of X-ray (EDAX ) tech-
niques have been used to study interface between carbon/silicon carbide (C
/SiC ) composite implant and bone. The C/SiC was inserted in lower jaw of
the two rabbits for 4-months. It is shown that the C/SiC composite provids
for excellent hard-tissue and softtissue biocompatibilities. The intimate
contact between C/SiC implant and bone is observed. An new interesting
phenomenon is that the content of calcium (Ca ) in implant adjacent to the
interface have obviously increased for 4 months postimplantation.
