Problems solved by technology

[0002] Dental implants are currently one of the best methods for repairing missing teeth. Commonly used dental implants are connected to the bone tissue of the surrounding alveolar bone through a mechanical lock similar to screws. The interface fretting caused by this connection It is one of the important factors leading to the loosening and failure of dental implants, but there is no effective way to solve the bottleneck of interface fretting failure

Embodiment 1

[0034] Example 1: Ti-6Al-4V titanium alloy is selected as the base material of the titanium-based implant, and the construction method of the present invention is used to construct a flexible porous structure layer on its surface. The construction method is: use NaOH solution in a closed container The surface of the titanium-based implant is subjected to high-temperature treatment for at least 1 hour, and nanotubes are grown on the surface of the titanium-based implant in situ, and then the nanotubes formed by the growth are constructed into a flexible porous structure layer. The construction method is specific Include the following steps:

[0035] 1) The titanium-based implant was ultrasonically cleaned with acetone for 2 minutes, then with absolute ethanol for 2 minutes, then with deionized water for 2 minutes, and dried naturally;

[0036] 2) Soak the titanium-based implant in an airtight container filled with a NaOH solution with a concentration of 1.0mol / L, and perform su...

Embodiment 2

[0039] Embodiment 2: Select medical titanium metal TA4 as the base material of the titanium-based implant, and adopt the construction method of the present invention to form a flexible porous structure layer on its surface. The construction method is: use NaOH solution to treat titanium in a closed container. The surface of the titanium-based implant is subjected to high-temperature treatment for at least 1 hour, nanotubes are grown in situ on the surface of the titanium-based implant, and then the nanotubes formed by the growth are constructed into a flexible porous structure layer. The construction method specifically includes the following steps :

[0040] 1) The titanium-based implant was ultrasonically cleaned with acetone for 2 minutes, then with absolute ethanol for 2 minutes, then with deionized water for 2 minutes, and dried naturally;

[0041] 2) Soak the titanium-based implant in a closed container filled with a NaOH solution with a concentration of 1.0mol / L, and pe...

Abstract

The invention discloses a dental implant surface flexible structure which comprises a flexible porous structure layer constructed by nano-pipelines. The nano-pipelines grow on the surface of a titanium-based implant in situ, and a main component of the nano-pipelines is Na2Ti2O5 or Na2Ti3O7. Pores in the flexible structure disclosed by the invention are beneficial for bone tissues to grow into the flexible porous structure layer to form a biological composite structure with a nano-pipeline-bone tissue three-dimensional staggered morphology with the nano-pipelines, and are beneficial for enhancing the bone bonding strength of the implant and an alveolar bone interface. The flexible structure disclosed by the invention has super-hydrophilic performance, certain elasticity and excellent tensile property, after the flexible structure disclosed by the invention is added to the surface of the titanium-based implant, the tribological coefficient of the surface of the titanium-based implant cannot be increased, and the planting difficulty of clinicians in the using process cannot be increased. According to a construction method of the flexible structure, which is disclosed by the invention, simple NaOH solution is used for treatment, i.e., in-situ growth is carried out on the surface of the titanium-based implant to form the nano-pipelines, and operability is high.

Description

technical field [0001] The invention belongs to the field of oral implants, and in particular relates to a flexible structure on the surface of a dental implant and a construction method thereof. Background technique [0002] Dental implants are currently one of the best methods for repairing missing teeth. Commonly used dental implants are connected to the bone tissue of the surrounding alveolar bone through a mechanical lock similar to screws. The interface fretting caused by this connection It is one of the important factors leading to the loosening and failure of dental implants, but there is no effective way to solve the bottleneck of interface fretting failure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flexible dental implant surface structure and a construction method thereof in view of the deficiencies in the prior art. The pores of the flexible porous structure layer constructed on the surface of...
