Abstract:

BACKGROUND: Studies have shown that modifying implant surface through chemical, physical, biological means can enhance the biological activity and favor the occurrence of osseointegration effectively.

OBJECTIVE: To review and compare the effects of different methods of surface modification of titanium on osseointegration.
METHODS: The CNKI, Wanfang, and PubMed were searched by computer using the keywords of “pure titanium, implants, plant, the surface of the implant, surface modification, biological activity, biocompatibility, osseointegration, research progress” in Chinese and English, respectively.
RESULTS AND CONCLUSION: Titanium has good biocompatibility, stable chemical properties and high fracture strength, and therefore it is widely used in implant repair. But titanium is a kind of biological inert material, and shows poor biocompatibility and biological activities. Titanium implants directly implanted into the body is bad for the occurrence of osseointegration. For improving the occurrence of implant osseointegration, the modification of titanium metal surface is one of the most effective methods. Most of the studies have shown that after modification, the implants with osteoinduction effect can promote adhesion, proliferation, differentiation and mineralization of bone cells on the surface. The surface treatment of implants is an important way to improve the performance of implants, such as physics, chemistry, biochemistry modification and so on. After modification, the surface morphology, chemical composition, surface roughness and hydrophilicity of implants can be altered, so as to improve the biocompatibility and biological activity of the titanium implants, and to promote the occurrence of osteoinduction.
