Embodiment 1

[0023] Such as figure 1 As shown, the dental implant 3 prepared in this embodiment is specifically arranged on the lower end of the abutment 2 , and the dental crown 1 is fixedly arranged on the upper end of the abutment 2 . The preparation of described dental implant 3 specifically comprises the following steps:

[0024] The cylindrical dental implant is treated with a surface nano treatment machine to make the implant form a surface nanostructure, such as figure 2 As shown, the surface grain size reaches about 10-50nm.

[0025] Then use 0.5mol / L hydrochloric acid to treat the nanometer surface, so that the surface nanostructure forms micron-scale holes, such as image 3 As shown in a and 3b, the diameter of the micron-sized holes is 100 nm-10 μm, and the micron-sized holes are evenly distributed on the surface of the dental implant.

Embodiment 2

[0027] A surface nano treatment machine is used to process the cylindrical dental implant, so that the implant forms a surface nano structure, and the surface grain size reaches about 50-100nm.

[0028] Then, 1mol / L hydrochloric acid is used to treat the nanometer surface to form micrometer-sized holes on the surface nanostructure. The diameter of the micrometer-sized holes is 100nm-10μm, and the micrometer-sized holes are evenly distributed on the surface of the dental implant.

Embodiment 3

[0030] A surface nano treatment machine is used to process the cylindrical dental implant, so that the implant forms a surface nano structure, and the surface grain size reaches about 100-500nm.

[0031] Then, 1mol / L hydrochloric acid is used to treat the nanometer surface, so that micron-scale holes are formed on the surface nanostructure. The diameter of the micron-scale holes is 100nm-10μm, and the micron-scale holes are evenly distributed on the surface of the dental implant.

Abstract

A dental implant with a surface nanostructure and a preparation method thereof in the field of dental medical technology. The dental implant has a cylindrical structure, a surface grain size of 1 nm to 500 nm, and a uniformly distributed micron-level hole structure. The dental implant prepared by the present invention has good bone tissue compatibility, can induce bone deposition and bone ingrowth faster, improves the bonding rate between the implant and the bone tissue, and enhances the bonding between the dental implant and the bone tissue. Bonding strength, thereby improving the long-term clinical stability and success rate of dental implants.

Description

technical field [0001] The invention relates to a product in the field of dental medical technology and a preparation method thereof, in particular to a dental implant with a surface nanostructure and a preparation method thereof. Background technique [0002] Dental implants can reduce or eliminate bases, bring comfort and aesthetics to patients, restore masticatory function to the greatest extent, promote bone tissue metabolism, delay alveolar bone resorption, and improve patients' quality of life. widely used. Clinical implants are mainly divided into metals and their alloys, ceramics, polymer materials and carbon-based materials. Among them, metal materials such as pure titanium, titanium alloy, and stainless steel have the advantages of good biocompatibility, suitable mechanical properties, and corrosion resistance, and are commonly used dental implants. However, the low interface bonding force between implant and bone tissue and poor long-term stability are the main ...
