Embodiment 1

[0042] This embodiment provides a surface treatment process for dental implants, including:

[0043] The surface of the implant was blasted with rutile sand with a mesh number of 35. The sandblasting process is as follows: the angle between the spray gun and the implant is 45°, the distance between the gun nozzle and the implant is 8mm, and the sandblasting time for each implant is 15s.

[0044] After sandblasting, the implants are cleaned and put into acid solution for acid etching. The acid solution includes sulfuric acid, hydrochloric acid and water in a volume ratio of 1:1:2. The acid etching time is 50min, and the acid etching temperature is 65°C. After the acid etching was completed, the implants were ultrasonically cleaned twice in absolute ethanol and deionized water, each time for 10 min.

[0045] The cleaned implant was heated and soaked in NaOH solution with a concentration of 5 mol / L for 24 hours, and the soaking temperature was 60°C. After soaking, cleaning is...

Embodiment 2

[0047] This embodiment provides a surface treatment process for dental implants, including:

[0048] The surface of the implant was blasted with rutile sand with a mesh number of 35. The sandblasting process is as follows: the angle between the spray gun and the implant is 45°, the distance between the gun nozzle and the implant is 8mm, and the sandblasting time for each implant is 15s.

[0049] After sandblasting, the implants are cleaned and put into acid solution for acid etching. The acid solution includes HF, hydrochloric acid and water in a volume ratio of 1:1:2. The acid etching time is 40min, and the acid etching temperature is 55°C. After the acid etching was completed, the implants were ultrasonically cleaned twice in absolute ethanol and deionized water, each time for 10 min.

[0050] The cleaned implant was heated and soaked in NaOH solution with a concentration of 5 mol / L for 24 hours, and the soaking temperature was 60°C. After soaking, cleaning is carried ou...

Embodiment 3

[0052] This embodiment provides a surface treatment process for dental implants. The difference from Embodiment 1 is that the mesh number of the rutile sand is 10 mesh.

Abstract

The invention relates to a surface treatment process of a dental implant and an application thereof, and belongs to the technical field of dental implanting. The surface treatment process of the dental implant includes the steps of carrying out acid etching treatment of an implant treated by rutile sand blasting and carrying out alkali treatment of the implant subjected to acid etching treatment.Sand blasting treatment on the surface of the implant with rutile sand makes the surface of the pure titanium implant free from interference of other impurity elements, and first-order holes can be effectively formed by large-particle sand blasting to promote bone bonding. Acid etching treatment can control the size and distribution of the holes on the implant surface, and makes the implant easierto bind to cells. Alkali treatment after acid etching can change the surface structure of the implant, so the implant has good hydrophilicity, can better perform direct interaction with proteins andcells in body fluid, and has higher biological activity.

Description

technical field [0001] This application relates to the technical field of dental implants, and in particular to a surface treatment process and application of dental implants. Background technique [0002] Implant surface topography is one of the important factors affecting osseointegration. Studies have found that the osseointegration strength of titanium implants with a multi-level hole structure is greater than that of smooth surface implants, and high surface roughness is more conducive to the adhesion of osteoblasts. Some existing implant products have uneven pore structure or no multi-level pore structure, which is not conducive to early osseointegration. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the embodiment of the present application includes providing a surface treatment process and application of a dental implant, and the method optimizes the surface structure of the implant. [0004] In the first aspect, ...
