摘要:

文题释义:
钛(合金)是以钛为主体元素的金属生物材料,包括纯钛和钛合金。纯钛具有无毒、质轻、耐腐蚀性和生物相容性好等优点,但其强度较低,耐磨损性能较差,不适于大承载植入器械。钛合金相对于纯钛,其强度更高,加工性能更好,包括Ti6Al4V、无V钛合金如Ti5Al2.5Fe和Ti6Al7Nb,以及无V无Al钛合金。该文重点关注纯钛和Ti6Al4V。
钽:以钽为主体元素的金属生物材料。钽的原子序数是73,熔点高(达2 986 ℃),密度大(达16.65 g/cm3),韧性好,具有极强的耐腐蚀性,与体液无反应,生物相容性良好,是一种优良的骨科材料。文章重点关注本体钽材和涂层钽。

背景:钽和钛(合金)是目前临床应用最广泛的骨科生物材料,尤其是钽基生物材料,以其优异的耐腐蚀性和骨整合性而被临床医生所青睐。但有关钽基生物材料在骨科应用中是否优于钛(合金),现有研究并无定论。
目的:综述比较性研究钽与钛(合金)生物学性能的文献,分析造成钽和钛(合金)材料体内外生物相容性异同的可能原因。
方法:应用计算机在中国知网、万方、PubMed数据库检索涉及比较性研究钽和钛(合金)的体内外生物学性能的相关文献,检索题目中含有“钽(tantalum)”且题目或摘要中含有“钛(titanium)”,即(tantalum[Title])) AND (titanium[Title/Abstract])的文献,检索截止时间为2020年1月。
结果与结论:在关于比较性研究钽和钛(合金)生物学性能的文献中,临床观察、动物实验、细胞实验结果的结论主要分为2类,一类是认为钽的促成骨能力和抗菌活性优于钛(合金),另一类认为钽与钛(合金)具有相似的促成骨能力和抗菌活性。造成这两种差异性结果的原因主要是钽和钛(合金)的加工方法和表面化学组成、拓扑结构或孔结构等理化性能指标存在差异。

Abstract: BACKGROUND: Tantalum and titanium (alloy) are the most widely employed metallic biomaterials in orthopedics. Tantalum is especially focused because of its excellent corrosion resistance and osteointegration. However, whether tantalum is better than titanium (alloy) as orthopedic materials is still in dispute.
OBJECTIVE: To review the comparative studies on the biological performances of tantalum and titanium (alloy) and analyze the possible causes of the similarities and differences of biocompatibility of tantalum and titanium (alloy) materials in vivo and in vitro.
METHODS: A computer-based search of CNKI, Wanfang and PubMed database was performed for articles relating to the comparative studies on the biological performances of tantalum and titanium (alloy) published until January 2020. The search words were “tantalum” in title and “titanium” in title or abstract, i.e., (tantalum[Title])) AND (titanium[Title/Abstract]). 
RESULTS AND CONCLUSION: Among the comparative studies on the biological performances of tantalum and titanium (alloy), two viewpoints were primarily involved according to the results from clinical follow-up, animal tests, and cellular experiments. One is that tantalum is superior to titanium (alloy) with better osteogenesis and bone formation and stronger antibacterial activity, while the other one is that tantalum has similar osteogenesis and bone formation and antibacterial activity to titanium (alloy). The primary reason responsible for this divergence is that the fabrication method and the surface chemistries, topographical structures or pore structures are different between the employed tantalum and titanium (alloy).
