AI Technical Summary

Problems solved by technology

However, there are still some unresolved technical problems in the above-mentioned implants, mainly because the material itself does not have the function of promoting or inducing osteogenesis. After the material is implanted into the bone, it takes a long time to form an osseointegration with the bone tissue.

Abstract

The invention discloses a method for preparing TiSrO on the surface of a titanium implant 3 Coating method. In this method, the pure titanium implant is subjected to sandblasting and double acid treatment, and then placed in a hydrothermal solution containing strontium ions for hydrothermal treatment surface modification, and a layer of multi-level pores and nano-scale protrusion structures can be formed on the surface of the implant. The appearance of the protuberance-containing layer on the surface is strontium titanate crystal structure and anatase crystal phase structure, which can promote the differentiation of osteoblasts and stem cells into bone, and has good wettability, so it has a wide range of application values .

Description

technical field [0001] The invention relates to a bioactive artificial tooth root implant, in particular to a preparation of TiSrO on the surface of a titanium implant 3 Coating method. Background technique [0002] For the surface structure of implants, people have made many attempts, such as smooth surface machined, rough surface sprayed with hydroxyapatite, rough surface sprayed with titanium slurry, etc., after long-term follow-up research. It has been generally accepted that implants with a rough surface and a threaded structure are more conducive to osseointegration, and the rough surface formed by sandblasting and acid etching has more advantages, which is more conducive to guiding osteoblast chemotaxis than the rough surface formed by spraying. Accelerates osseointegration. [0003] The surface of the Branemark implant and Replace? implant produced by Sweden Norbel-pharma company adopts TiUnite? surface (porous titanium oxide structure) or hydroxyapatite coating (b...
