Titanium metal osseointegration implant and titanium metal osseointegration implant surface treatment method

Abstract

The invention relates to a titanium metal osseointegration implant, which comprises an implant body, wherein the ragged coarsening bonding surface is formed on the surface of the implant body through sandblasting, shot blasting, plasma titanium spraying or electrolytic corrosion, and the coarsening bonding surface on the implant body surface forms the clean bonding surface having micro pores through acid liquid corrosion. According to the present invention, after the acid corrosion treatment on the implant, the surface impurities can be removed, the osseointegration strength can be increased, and the infection risk can be reduced. The titanium metal osseointegration implant surface treatment method comprises: 1, forming a ragged coarsening bonding surface on the surface of an implant through sandblasting, shot blasting, plasma titanium spraying or electrolytic corrosion; and 2, carrying out acid corrosion on the implant so as to form the clean coarsening bonding surface on the surface. In addition, the implant is treated so as to form the coarsening bonding surface on the surface, and then the acid corrosion treatment is performed, such that the impurities on the implant surface can be removed, the cleaning degree of the implant can be improved, and the infection risk can be reduced.

Description

technical field [0001] The invention relates to the technical field of orthopedic treatment, and more specifically relates to a titanium metal osseointegration implant and a surface treatment method for the titanium metal osseointegration implant. Background technique [0002] Since Professor Branemark of Sweden discovered and created the "osseointegration theory" of titanium metal in the 1950s, titanium metal was first promoted in dental implants. With the general recognition of the "osseointegration theory" of titanium metal, titanium metal It has also been widely promoted in orthopedic fields such as bone trauma, bone joints, bone cages, and various bone nails. [0003] The initial surface of titanium implants was only mechanically processed. With long-term clinical research, it was found that the rough surface of titanium metal is more conducive to osseointegration, and various surface roughening processes of titanium metal have also been produced, such as sandblasting. ...

AI Technical Summary

Problems solved by technology

[0007] 3. Various irregular cracks, micropores and other surface defects will be formed during the roughening process, which will cause some liquid media in the subsequent process, such as cleaning liquid and processed cooling oil, to penetrate into it

In the final cleaning process such as ultrasonic cleaning, it is difficult to clean out the impurities in these micro-gaps, and these oily impurities are very unfavorable for osseointegration.
