摘　　要：根据骨的压电现象 ,从细胞、组织、力学和电学相容性的角度分别考察了压电陶瓷材料与骨组织的生物相容性。结果显示该压电陶瓷材料与骨组织的生物相容性良好 ,对细胞的生长形态和增殖情况无不良影响 ;材料——骨界面形成骨性结合 ;材料的力学性能亦能满足要求 ;尤其在与骨组织的压电性能相匹配方面展现了优势 ,可引导新生骨质定向沉积。显示了压电陶瓷作为一种新型的修复材料的良好应用前景。Based on the piezoelectric effect of nature bone, the biocompatibility of a piezoelectric ceramic and bone tissue is observed and studied in four aspects, cytocompatibility, tissue-compatibility, mechanical compatibility and electro-compatibility. The results show that the piezoelectric ceramic is biocompatible. It is not harmful to the morphology and proliferation of L929. There is osteal combination between the piezoelectric ceramic and bone. Its mechanical properties are also suitable for bone replacement. Especially, it can induce the growth of osseous tissues along the chosen direction according to the piezoelectric properties of bone. It is envisaged that the piezoelectric ceramic may be developed and used as a novel material for bone replacement.
