Problems solved by technology

However, a large number of applications of the above methods will produce drug resistance and cross-resistance. By regulating the surface, obtaining an antibacterial technology method and implant products that reduce bacterial adhesion and biofilm formation will have important research and clinical use values.

Embodiment 1

[0042] (1) Place the pure titanium implant matrix in a cleaning tank containing a surfactant (specifically PWC-401 cleaning agent, the same below), perform ultrasonic degreasing and cleaning at 60-70°C for 10 minutes, and rinse with purified water Drying, then pickling treatment at room temperature for 15 seconds in an acidic mixed solution containing 12% nitric acid and 5% hydrofluoric acid by volume fraction, rinsed with purified water, and dried for use;

[0043] (2) Put the clean implant matrix in a sandblasting machine, and use 80 μm and 180 μm ceramic sand at a mass ratio of 1:1 for sandblasting treatment under the condition of a pressure of 5 bar and a distance of 0.5 cm. After sanding, the implants were ultrasonically cleaned in acetone, ethanol, and deionized water for 10 minutes, and then placed in a solution containing 15wt% sulfuric acid, 8wt% hydrochloric acid, 1wt% nitric acid, 0.2wt% ethylene glycol, and 0.02g / L perfluorooctanesulfonic acid. Perform high-tempera...

Embodiment 2

[0049] (1) Place the pure titanium implant matrix in a cleaning tank containing surfactant, ultrasonically degrease and clean it at 60-70°C for 10 minutes, rinse with purified water and then dry it. and 5% hydrofluoric acid in an acidic mixed solution at room temperature for 15 seconds, rinsed with purified water, and then dried for use;

[0050] (2) Put the clean implant matrix in the prepared micro-arc oxidation treatment solution (1L of micro-arc oxidation treatment solution contains 6g of calcium formate, 6mL of sulfuric acid, 4mL of hydrochloric acid and 6g of polypropyleneimine with a number average molecular weight of 4000) Among them, the implant matrix is ​​used as the anode, and the stainless steel is used as the cathode, and the DC pulse micro-arc oxidation bioceramic equipment is used for micro-arc oxidation treatment. The process parameters of the micro-arc oxidation are set as: constant voltage mode, and the working voltage adjustment range is forward voltage 150 ...

Embodiment 3

[0055] (1) Place the pure titanium implant matrix in a cleaning tank containing surfactant, ultrasonically degrease and clean it at 60-70°C for 10 minutes, rinse with purified water and then dry it. and 5% hydrofluoric acid in an acidic mixed solution at room temperature for 20 seconds, rinsed with purified water, and then dried for use;

[0056] (2) Put the clean implant matrix in the prepared micro-arc oxidation treatment solution (1L micro-arc oxidation treatment solution contains 8g calcium acetate, 3mL sulfuric acid, 4mL nitric acid and 9g sodium ethylenediene triamine pentaacetate), With the implant matrix as the anode and stainless steel as the cathode, the micro-arc oxidation treatment is carried out with the DC pulse micro-arc oxidation bioceramic equipment. The process parameters of the micro-arc oxidation are set as: constant voltage mode, and the working voltage adjustment range is forward voltage 150~300V , Negative voltage 0V, pulse frequency 100Hz, duty cycle 5%...

Abstract

The present invention belongs to the fields of dental implants and surface treatment, and relates to a dental implant, an implant tooth and a preparation method of the dental implant. The dental implant is divided into two parts of a neck region and a body region along an axial direction, and the neck region has anti-microorganism properties and the body region has osteogenic properties by controlling a surface microstructure. The provided dental implant has super hydrophilicity / hydrophobicity. Aiming at the neck region of the dental implant, the specific structure based on the structure enables the dental implant to have super hydrophobicity and anti-microorganism functions, solves a major clinical demand that adhesion and proliferation of oral bacteria in junction areas between soft andhard tissues of the dental department lead to peri-implant inflammation to cause loss of the implant, and forms an effective biological seal; and aiming at the implant body, a multi-level micron morphology based on the surface structure enables the dental implant to have super hydrophilicity, and is also more conducive to adhesion and proliferation of osteoblasts.

Description

technical field [0001] The invention belongs to the field of dental implants and surface treatment, and in particular relates to a dental implant used for replacement in case of loss and defect, an implant tooth and a corresponding preparation method thereof. Background technique [0002] The dental implant is divided into two sections along the axial direction, one is the body area of ​​the dental implant, which is in contact with the hard tissue of the dental alveolar bone; the other is the neck area of ​​the dental implant, which is in contact with the marginal dental Groove bone and soft tissue contact. To achieve and restore the occlusal function of teeth, dental implants need to achieve rapid osseointegration and prevent bacteria from adhering to the upper neck area of ​​the implant, so as to prevent bone resorption due to peri-implantitis caused by bacterial adhesion and growth to form a bacterial film , eventually leading to the problem of implant loss.
