Problems solved by technology

However, one or more of sulfuric acid, phosphoric acid, hydrochloric acid, and nitric acid is still used as the compounding agent of the electrolyte in this method, which is dangerous to the operator during use and does not meet the requirements of environmental protection; The auxiliary additives of the liquid use polymer compounds such as polyacrylamide. Polyacrylamide is synthesized from monomer acrylamide. Monomer acrylamide is a neurotoxic agent that can damage the nervous system. The coating prepared by this method is micro There may be toxic substances in the pores, and its safety needs to be further confirmed; the oxide layer map obtained by this method shows that the surface of the substrate is an anatase titanium dioxide film, but the anatase TiO 2 lower content

Abstract

The invention relates to the technical field of treatment of oral cavity dental implant surfaces and in particular relates to a preparation method of an anatase type micron-grade tubular structure active coating of a titanium and titanium alloy dental implant surface. The preparation method comprises the following steps: carrying out sand-blasting roughening treatment on the titanium and titaniumalloy dental implant surface; carrying out ultrasonic washing and drying on the implant surface; taking the implant as an anode and putting the implant into oxidized electrolyte; taking a stainless steel sheet as a cathode and carrying out liquid-state plasma oxidization treatment to form a two-grade micro-pore active coating; after carrying out the ultrasonic washing and hot water washing on theimplant, drying by blowing compressed air. According to the anatase type micron-grade tubular structure active coating prepared by the preparation method, a first-grade hole has a typical micron-gradetubular structure feature and a second-grade hole and the first-grade tubular structure hole has height difference to form a gradient structure, so that the surface roughness of the coating is extremely increased.

Description

technical field [0001] The invention relates to the technical field of surface treatment of oral dental implants, in particular to a method for preparing an anatase-type micron-scale tubular structure active coating on the surface of titanium and titanium alloy dental implants. Background technique [0002] Since Professor Branemark put forward the theory of osseointegration in the 1870s, implant technology has been widely used and achieved success in the field of oral cavity. Osseointegration is considered to be an important indicator to measure the success of implant. The surface morphology and surface activity of the implant itself are the key factors affecting the osseointegration strength. Studies in recent years have shown that rough surfaces can stimulate cell activity, promote good osseointegration at the implant-bone interface, and improve the success rate of implant surgery. The rough surface increases the surface area of ​​the implant without changing the volume ...
