(Summary description)At present, the application of dental implant prosthesis in stomatology is more and more widely, and titanium is the common material of dental implant system. Titanium is a kind of inert metal material with poor biological activity, which is easily wrapped by a layer of fibrous membrane after implantation. Lack of initiative in the process of osteosynthesis leads to long time of osteosynthesis, poor initial stability and low long-term success rate. At the same time, the low hardness, fatigue strength and wear resistance of pure titanium lead to the loosening of abutment fastening screws, pitting, wear and corrosion failure of connection threads during the use of titanium implants, which greatly reduces the reliability and service life of the implant system. After the treatment and modification by the isoion equipment, the water droplets from the contact Angle tester slipped from the top of the implant, and the Angle value could not be determined and approached 0. It has been proved by previous experiments that the surface of dental titanium implants becomes superhydrophilic after plasma treatment under the corresponding process gas and other conditions, which plays an important role in medical treatment. The special wettability is one of the important properties of surface materials, mainly determined by the microscopic geometry and chemical composition of the surface material, because of its unique physical and chemical properties and its successful application in finishing, lubrication, bonding, foam, waterproof and biomedical materials has aroused a lot of interest. The adsorption and proliferation experiments of osteoblasts showed that the oxidized surface of plasma equipment had better biological activity than that of heat treatment. We tried to prepare superhydrophobic surface through molecular self-assembly, and the contact Angle was higher than 130 degrees. The conversion and control between superhydrophilicity and superhydrophobicity can be realized by plasma modification in plasma equipment.
