Problems solved by technology

The dental implant obtained by this method has a micro-nano multi-level microstructure, which solves the problem of insufficient bonding between the surface structure and the base; With the prolongation of the storage time, the chance of the surface of the dental implant being polluted by hydrocarbons in the air is greater, and the biological activity of the dental implant is lower; there are researches on the bone contact rate of the uncontaminated implant with the new surface treatment ( BIC) can reach more than 90%, while the aged pure titanium implant BIC is only less than 60%, and after ultraviolet (UV) irradiation can reach 100% BIC, this is because UV irradiates TiO 2 The photocatalytic effect occurs to generate photogenerated hole-electron pairs with strong redox ability, and the TiO 2 Hydrocarbon degradation of surface contamination makes it have a higher BIC than newly treated pure titanium implants, but UV is inconvenient in clinical use, and poor protection will hurt the surrounding medical staff and patients, and generate ozone, etc. harmful gas

Embodiment 1

[0036] A dental implant, the surface of which is treated by:

[0037] 1) Cleaning of pure titanium dental implants: Ultrasonic cleaning of pure titanium dental implants with acetone, absolute ethanol, and deionized water for 15 minutes each, and natural drying;

[0038] 2) Sand blasting treatment: the dental implant treated in step 1) is sprayed with aluminum oxide particles with a diameter of 120 μm under 0.45 MPa air pressure, the nozzle is 1 cm away from the pure titanium implant, and the nozzle is perpendicular to the dental implant and sprayed evenly for 30 seconds, so that The surface of the dental implant has uniform primary holes; then it is ultrasonically cleaned with acetone, absolute ethanol, and deionized water for 15 minutes, and then dried naturally;

[0039] 3) Surface acid etching treatment: Mix 18% HCL and 49% H2SO4 with deionized water to mix the prepared hydrochloric acid and sulfuric acid at a volume ratio of 1:1, and completely immerse the dental implant a...

Embodiment 2

[0047] A dental implant, the surface of which is treated by:

[0048] 1) Cleaning of pure titanium dental implants: Ultrasonic cleaning of pure titanium dental implants with acetone, absolute ethanol, and deionized water for 10 minutes each, and natural drying;

[0049] 2) Sand blasting treatment: spray the dental implant treated in step 1) with aluminum oxide particles with a diameter of 100 μm under 0.45 MPa air pressure, spray the nozzle 0.5 cm away from the dental implant, and spray the nozzle perpendicular to the dental implant for 20 seconds, so that The surface of the dental implant has uniform primary pores; then it is ultrasonically cleaned with acetone, absolute ethanol, and deionized water for 10 minutes, and then dried naturally;

[0050] 3) Acid etching treatment on the surface of pure titanium implant: use deionized water to prepare 18% HCl, 49% H 2 SO 4 Mix the prepared hydrochloric acid and sulfuric acid at a volume ratio of 1:1, completely immerse the dental...

Embodiment 3

[0058] A dental implant, the surface of which is treated by:

[0059] 1) Cleaning of pure titanium dental implants: Ultrasonic cleaning of pure titanium dental implants with acetone, absolute ethanol, and deionized water for 20 minutes each, and natural drying;

[0060] 2) Sandblasting treatment: spray the dental implant treated in step 1) with aluminum oxide particles with a diameter of 150 μm under 0.45 MPa air pressure, spray the nozzle 1.5 cm away from the dental implant, and spray the nozzle perpendicular to the dental implant for 40 seconds, so that The surface of the dental implant has uniform primary holes; then it is ultrasonically cleaned with acetone, absolute ethanol, and deionized water for 20 minutes, and then dried naturally;

[0061] 3) Surface acid etching treatment: Mix 18% HCL and 49% H2SO4 with deionized water to mix the prepared hydrochloric acid and sulfuric acid at a volume ratio of 1:1, and completely immerse the dental implant after step 2) in the bis ...

Abstract

The invention discloses a dental implant and a surface treatment method thereof. The surface treatment method for the dental implant comprises the following steps of dental implant cleaning, sandblasting, surface acid etching, surface nanocrystallization processing, soaking, calcinating, and cleaning and the like, so that the dental implant adopting a micron and nanometer mixed structure and having the visible-light catalytic activity through nitrogen doping is obtained. The dental implant achieves preferable hydrophilia, protein adsorption capacity and good biological activity.

Description

[0001] technical field [0002] The invention relates to the technical field of biomedicine, in particular to a dental implant and a surface treatment method thereof. [0003] Background technique [0004] Dental implant refers to a kind of medical device that is surgically implanted into the jawbone to fix and support dentures; the fixation method can be transgingival, that is, a part of the dental implant is exposed outside the gums as a foundation post; or completely buried Placed under the gums only to support removable dental restorations. According to needs, dental implants can be made into various shapes such as cylinders, blades, and spirals, and can be composed of different materials such as metals, ceramics, polymers, or natural substances, or composited from the aforementioned materials. [0005] At present, the surface treatment methods of dental implants mainly include sandblasting and acid etching, laser treatment, micro-arc oxidation and other methods. The s...
