Problems solved by technology

However, photocatalysis is not enough to rely solely on the nanometer-thick titanium dioxide film formed by the spontaneous oxidation of pure titanium surface in air, and there is still a lot of room for improvement.

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] The invention cleans the surface of pure titanium through the photocatalysis of titanium dioxide, which can effectively remove the pollutants adsorbed on the surface of pure titanium in the air, eliminate these factors affecting early osseointegration, promote the early cell reaction on the surface of pure titanium, and promote early osseointegration. The establishment of the integration shortens the clinical treatment time, thereby improving the success rate of dental implants.

[0034] A method for titanium dioxide photocatalytically cleaning the surface of pure titanium, comprising the following steps:

[0035] S1. Weigh 90-100mg of nano-titanium dioxide particles and dissolve them in 450-500ml of deionized aqueous solution, and fully stir and mix;

[0036] S2. Put the deionized aqueous solution obtained in S1 into a container, and put a titanium s...

Abstract

The invention relates to a method for photocatalytic cleaning of a pure titanium surface by titanium dioxide. The method particularly comprises the steps of deionized water mixing stirring, cleaning,flowing circulation, ultraviolet light irradiation, ultrasonic cleaning, ray sterilization and the like. The invention also provides a device for realizing the method. The method and the device provided by the invention can more effectively remove pollutants on the pure titanium surface and promote the early cellular reaction on the pure titanium surface, so that establishment of the early bone integration is promoted, the success rate of oral clinical titanium implants is improved, and the method and the device can be widely applied to the technical field of medical auxiliary equipment.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a method and system for photocatalytically cleaning the surface of pure titanium with titanium dioxide. Background technique [0002] Numerous studies have confirmed that the surface cleanliness of titanium implants greatly affects its biological activity and early osseointegration. However, the titanium dioxide film layer on the surface of pure titanium will absorb inorganic ions and organic pollutants in the air within 1 minute or even a few seconds, changing the chemical composition of the surface. These pollutants reduce the biological activity of the surface and are not conducive to the early formation of osseointegration. . In addition, there is an "aging" phenomenon on the surface of pure titanium, that is, the biological activity of the surface decreases with time, and the bone conduction function decreases, which inhibits the chemotaxis of osteoblast...
