摘要
As an important factor affecting the biocompatibility of implant, the surface micromorphology and chemical composition of the biomedical titanium implant determine the stability and service life of the implant, and have been widely studied. It is extremely important to systematically review the research status of surface modification of titanium implants. This paper reviews the research status of the construction of micro-nano structure on the surface of titanium implants and the addition of typical bioactive ions, and the synergistic effects of the combination of the two on promoting cell adhesion, proliferation, differentiation and promoting osteogenesis in animals. Besides, this paper briefly describes the internal regulation mechanism of micro-nano structure on cell behavior. The review indicates that the micro-nano structure and bioactive ions on the surface of titanium implants have a positive effect on the behavior of cells, and implants with both can better promote cell adhesion, proliferation and differentiation. It is more conducive to the osseointegration of the implant and the surrounding tissue after in vivo. Finally, according to the problems of poor antibacterial performance and unclear effect on cells in the current research on surface modification of biomedical titanium implants, the research trend in the field of surface modification is proposed. The research status and future development direction of micro-nano structure construction and bioactive ions addition in the field of titanium implant surface modification are proposed, This paper fills the gap in the surface modification of titanium implant and provides a reference for the future development of titanium implant surface modification. © 2022 Chinese Mechanical Engineering Society.
