摘要
早在20世纪50年代研究已发现,在应力作用下生物骨表面的电荷会发生重排,产生电信号,具有压电效应。骨的这种压电特性提示,如果将电活性成分加入移植材料,可能会有助于提高骨的形成速度和质量。随着科学技术的发展以及研究的深入,工业用压电材料已被作为骨替代材料引入医疗领域,模仿生成骨表面电荷从而促进骨愈合。本文就骨压电效应以及压电材料促进成骨机制等方面做简要说明,并对骨组织植入用压电材料的研究与发展前景做一综述。
In the 1950s, studies had found that mechanical stress could rearrange the charges and produce electricity on the surface of the bone. This is called piezoelectric effect. Piezoelectric properties of the bone imply that adding a certain of active electric ingredients to transplant materials may increase the formation speed and the quality of the bone. With the development of science and technology, the piezoelectric materials in industry have been widely introduced into medical field as the bone substitute materials, generating charges on the surface of the bone to promote the bone healing. In this paper, we briefly introduce the piezoelectric effect of the hone, osteogenesis mechanism of piezoelectric materials, and review the progress of the research on piezoelectric materials for bone replacement.
