摘要:

文题释义:
钛植入物骨整合:是指在人体活的骨组织与钛种植体之间发生的牢固、持久而直接的结合,即负载力量的种植体的表面与有活力的骨组织之间存在结构上和功能上直接的联系,种植体与骨组织之间没有任何结缔组织存在,不间隔任何组织。
生物化学改性:起初是作为化学改性的变异出现,是指通过将特定的蛋白、多肽、生长因子、多糖和核苷酸固定于种植体表面,这样可使生物活性分子直接在骨与植入体之间发挥作用,诱导成骨细胞增殖、分化和矿化,更为直接有效地促进骨整合。

背景:钛及钛合金因具有良好的机械性能和生物惰性等被广泛应用于骨科植入领域。
目的:综述不同的生物分子搭载到钛植入物表面对骨整合的影响。
方法:由第一作者应用计算机以“titanium,osseointegration,biochemical modification,coating”为英文检索词,以“钛,骨整合,生物化学改性,涂层”为中文检索词,应用计算机检索PubMed、Web of Science、维普、万方、中国知网数据库中1991-2020年已发表的相关文献,并进行筛选、归纳与总结,最终纳入104篇相关文献进行综述。
结果与结论:钛植入体表面单一的物理和化学修饰方式主要是间接影响细胞行为,而生物分子涂层可以直接参与生物过程,这在诱导骨形成方面更有效,不仅显著提高了骨与植入体之间早期的骨整合,还降低了因炎症反应导致的手术失败及假体翻修发生率。虽然钛植入物的生物化学改性可以直接参与生物过程,但是目前还有许多问题尚待解决:生物活性物质在钛植入体表面的长期稳定性、释放的速率以及钛植入物与机体细胞和组织之间的作用机制问题还需进一步研究,从而得到骨与钛植入物之间的早期和长期的骨整合。

Abstract: BACKGROUND: Titanium and titanium alloys are widely used in the field of orthopedic implantation, because of their good mechanical properties and biological inertia.
OBJECTIVE: To review the effects of different biomolecules on titanium implant surface on osseointegration.
METHODS: PubMed, Web of Science, VIP, Wanfang, and CNKI were searched using “titanium, osseointegration, biochemical modification, coating” as keywords in Chinese and English for relevant articles published from 1991 to 2020. Finally, 104 articles were included in result analysis after screening and summarizing.
RESULTS AND CONCLUSION: The single physical and chemical modification of titanium surface is mainly affecting the cell behavior indirectly, and the biomolecular coatings can be directly involved in the biological process, which is more effective in bone formation, not only greatly improves the early osseointegration between bone and the implants, but also reduces the incidence of surgical failure and prosthesis revision due to inflammatory reaction. Although the biochemical modification of titanium implants can be directly involved in the biological process, there are still plenty of problems that need to be solved: the long-term stability, releasing rate, and mechanism between the implants and cells and tissues need to be further studied to achieve early and long-term osseointegration between bone and the implants.

Key words: titanium, implants, osseointegration, surface modification, biochemical modification, coating, biomolecule, osteogenic differentiation
