多孔钽在骨科和口腔医学领域应用的研究进展

Advances in the application of porous tantalum in orthopedics and stomatology

多孔钽小梁金属长期应用于骨科,可促进血管新生、伤口愈合和成骨;近期在钛合金牙种植体中多孔钽的应用也越来越多。多孔钽具有良好的生物相容性及与骨组织相似的弹性模量,与金属钛相比,它能明显促进原代成骨细胞的增殖和分化,促进骨结合,完成骨整合,从而显著提高种植体在骨组织中的二次稳定性,是目前已知最好的金属植入材料之一。现通过回顾以及分析相关文献,对多孔钽材料的特性以及其在骨科和口腔医学领域的应用研究进展作一综述。

Porous tantalum trabecular metal has long been used in orthopedics to promote angiogenesis, wound healing and osteogenesis. More recently, porous tantalum has been increasingly used in titanium alloy dental implants. Porous tantalum has become a popular graft material because of its good biocompatibility and elastic modulus similar to bone tissue. Compared with titanium, it can significantly promote the proliferation and differentiation of primary osteoblasts, and it is one of the best metal implant materials known at present. After implantation, porous tantalum can promote bone bonding and complete bone integration, thus significantly improving the secondary stability of implants in bone tissue. In this paper, relevant literature are reviewed and analyzed to introduce the properties of porous tantalum materials and their application in orthopedics and stomatology.
