Embodiment 1

[0041] A method for preparing an antibacterial surface of a dental implant, comprising the following steps:

[0042] S1: The dental implant matrix with titanium dioxide nanotube array coating on the outer surface is immersed in a polytetrafluoroethylene high-temperature and high-pressure hydrothermal kettle;

[0043] S2: Put the polytetrafluoroethylene high-temperature and high-pressure hydrothermal kettle in S1 in a low-temperature sintering furnace, and obtain dental implants by hydrothermal crystallization;

[0044] S3: antibacterial treatment: dental implant grinding treatment: the dental implant is polished with SiC metallographic sandpaper, and the surface of the dental implant is treated to a rough surface. Dental implant cleaning: the pure titanium dental implant is passed through acetone, no Ultrasonic cleaning with water ethanol and deionized water, and natural drying. Put the dental implant in a muffle furnace and heat it at a constant speed. Cool down to room temp...

Embodiment 2

[0052] A method for preparing an antibacterial surface of a dental implant, comprising the following steps:

[0053] S1: The dental implant matrix with titanium dioxide nanotube array coating on the outer surface is immersed in a polytetrafluoroethylene high-temperature and high-pressure hydrothermal kettle;

[0054] S2: Put the polytetrafluoroethylene high-temperature and high-pressure hydrothermal kettle in S1 in a low-temperature sintering furnace, and obtain dental implants by hydrothermal crystallization;

Abstract

The invention discloses an antibacterial surface of a dental implant and a preparation method thereof. The surface of the dental implant is treated with antibacterial treatment, the material of the dental implant is titanium base material or titanium alloy, and the thickness of the antibacterial coating is 50 ‑80nm, the surface of the dental implant is coated with an antibacterial coating, the antibacterial surface of the dental implant is soaked in buffer solvents and organic solvents through antibacterial treatment, which greatly improves the hardness and tensile strength of the dental implant. The antibacterial coating is added to improve the antibacterial property of the dental implant, which solves the problem that the existing dental implant cannot meet people's needs in terms of tensile strength, hardness and antibacterial performance.

Description

technical field [0001] The invention relates to a dental implant, in particular to an antibacterial surface of a dental implant and a preparation method thereof. Background technique [0002] 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. [0003] With the development of implant technology, dental implants have been widely used in the restoration of clinical dentition defects and missing patients. However, after titanium and t...
