Problems solved by technology

[0003] First, it cannot reduce the demand for three-dimensional bone volume around the implanted area, reduce the amount of clinical bone graft and reduce a series of complications caused by large-scale bone grafting; second, it cannot improve the stress distribution of the implant when it is subjected to external force, so that it does not uniform; third, it cannot reduce the attack rate of peri-implantitis, which is not conducive to the long-term success of implants

Abstract

The invention relates to a zirconium-based amorphous metal glass dental implant and a preparation method thereof, comprising: 30-65 parts of zirconium, 0-25 parts of titanium, 0-45 parts of copper, 0-20 parts of aluminum, silicon 0‑20 parts, 0‑10 parts of iron, 0‑10 parts of zinc, 0‑5 parts of silver, 0‑5 parts of palladium, the dental implant is an amorphous metallic glass cylindrical rod with a diameter of 2‑6mm and a length of 4‑13mm; The part of the dental implant located in the bone has a self-tapping thread structure with a pitch of 0.7-2mm and a thread depth of 0.3-0.6mm. The thread section is triangular. between the first thread and the third thread. The invention has good fracture resistance, good biocompatibility, moderate elastic modulus and certain antibacterial effect, and is a good metal implant material.

Description

technical field [0001] The invention relates to a bionic design, in particular to a zirconium-based amorphous metal glass dental implant and a preparation method thereof. Background technique [0002] Most of the existing dental implants are made of pure titanium or titanium alloy, which mainly have the following problems: [0003] First, it cannot reduce the demand for three-dimensional bone volume around the implanted area, reduce the amount of clinical bone graft and reduce a series of complications caused by large-scale bone grafting; second, it cannot improve the stress distribution of the implant when it is subjected to external force, so that it does not The third is that it cannot reduce the attack rate of peri-implantitis, which is not conducive to the long-term success of implants. Contents of the invention [0004] The purpose of the present invention is to provide a zirconium-based amorphous metal glass dental implant, which can significantly reduce the requir...
