本实验选用自行研制的复合生物陶瓷(简称CBC)植入4只成年杂种狗的下颌骨体部人造骨缺损处。术后3月处死动物获取标本,在组织学观察的同时,取部份标本经处理后用扫描电镜和X线能谱仪对该材料与骨组织结合界面进行观察研究、结果表明复合生物陶瓷与骨组织呈直线骨性结合。关于其结合机理,经分析认为可能与离子交换后Ca,P聚集界面和磷酸盐物质扩散沉积于界面有关。 In this experiment, 4 adult mongrel dogs were implanted with artificial bone defect of the mandibular body by self-developed composite bio-ceramic (CBC). Animals were killed after 3 months to obtain the specimens. At the same time of histological observation, some specimens were processed and observed by scanning electron microscopy and X-ray energy dispersive spectroscopy. The results showed that the composite bio-ceramic and Bone tissue was linear bony union. With regard to its binding mechanism, the analysis suggests that it may be related to the diffusion deposition of Ca and P aggregates and phosphate materials on the interface after ion exchange.
