Problems solved by technology

This film can improve the corrosion resistance of titanium and promote the deposition of calcium phosphorus layer on its surface, but because it is very thin (10-20nm), it is easily damaged and loses its protective effect

Embodiment 1

[0038] The surface treatment method of the dental implant of the present embodiment comprises the following steps:

[0039] (1) Pretreatment: Polish the titanium-based implant to be treated until its surface is smooth and ready for use;

[0040] (2) pickling treatment: the titanium-based implant pretreated in step (1) is placed in an acid solution for pickling, and is set aside;

[0041] (3) Drying treatment: the titanium-based implant after the pickling treatment in step (2) is cleaned and then dried for use;

[0042] (4) Surface anodic oxidation pretreatment: place the titanium-based implant after the drying treatment in step (3) in the surface anodic oxidation electrolyte for surface anodic oxidation, and set aside;

[0043] (5) Surface micro-arc oxidation treatment: place the titanium-based implant after the surface anodic oxidation pretreatment in step (4) in the surface micro-arc oxidation electrolyte for surface micro-arc oxidation, and set aside;

[0044] (6) Finished ...

Embodiment 2

[0100] The implants prepared by the surface treatment method of dental implants in Example 1 and the implants prepared in Comparative Examples 1-4 were respectively selected for testing (BIC and ITBC values), and the results are shown in Table 4.

[0101] Table 4 comparison of test parameters

[0102]

[0103] combine figure 1 , figure 2 , Table 4, it can be seen that compared with Comparative Examples 1-4, the surface shape of the implant prepared by the present invention is more suitable for the attachment of bone cells, and it can be seen that the implant prepared by the present invention shows the highest cell adhesion. In addition, as a result of histological examination and analysis, it was observed that the implant prepared by the present invention has more mature bone formation. It can be seen that the implant prepared by the present invention is an excellent biocompatible titanium-based implant.

[0104] In summary, the dental implant surface treatment method ...

Abstract

The invention discloses a surface treatment method for a dental implant and belongs to the technical field of dental planting. The method comprises the following steps of (1) pre-treatment: polishinga titanium-based implant to be treated till the surface of the implant is smooth; (2) pickling treatment: placing the titanium-based implant in an acid liquid for pickling; (3) drying treatment: drying the titanium-based implant after cleaning; (4) surface anodizing pre-treatment: placing the titanium-based implant in a surface anodizing electrolyte for surface anodizing; (5) surface micro-arc oxidation treatment: placing the titanium-based implant in a surface micro-arc oxidation electrolyte for surface micro-arc oxidation; and (6) product treatment: flushing the titanium-based implant and drying and storing the same. According to the surface treatment method in the invention, the prepared dental implant is higher in biocompatibility, so that the success rate of oral planting is improved,the treatment time is shortened, and the preparation method is simple and has a good application prospect in the field of oral planting.

Description

technical field [0001] The invention belongs to the technical field of dental implants, and in particular relates to a surface treatment method for dental implants. Background technique [0002] Because of its good biocompatibility, pure titanium is widely used in clinic as oral implant material. However, titanium implants still have many problems, such as poor biological activity, lack of osteoinductive effect, low bonding strength with surrounding tissues, release of metal ions, long healing time, and poor corrosion resistance. The initial implant surface was a machined surface without any treatment. Since pure titanium implants were widely used in the field of stomatology in the 1960s, scholars have tried a variety of surface modification methods to solve the above problems: such as optimizing The surface topography forms smooth, groove-like, and thread-like surfaces, that is, surfaces with different roughness or porosity; such as changing the surface elastic modulus; su...
