Titanium and titanium alloys are the main materials for implant preparation. Titanium can spontaneously form a high surface energy titanium dioxide surface in an air environment. However, this surface adsorbs inorganic ions and organic hydrocarbons in the air for a short period of time to produce a dense, Change the surface chemical composition and reduce its hydrophilicity. Part of the theory now tends to have a higher biological activity on the hydrophilic surface, facilitating osteoblast adhesion and stretching, thereby promoting early osteogenesis. Therefore, how to improve the hydrophilicity of titanium surface has become a hotspot. In this paper, several methods of improving the hydrophilicity of implants were analyzed and compared, and the osteogenesis effect was reviewed.
