Zirconium-based amorphous metallic glass dental implant and preparation method thereof

A dental implant and metallic glass technology, which is applied in dentistry, prostheses, dental implants, etc., can solve the problem of not reducing the three-dimensional bone requirement around the implant area, reducing the attack rate of peri-implantitis, and not improving the quality of implants. Stress distribution and other issues can be reduced to reduce the amount of clinical bone graft, which is conducive to long-term success and moderate elastic modulus.

Abstract

The invention relates to a zirconium-based amorphous metallic glass dental implant and a preparation method thereof. The zirconium-based amorphous metallic glass dental implant is prepared from the components in parts by weight: 30-65 parts of zirconium, 0-25 parts of titanium, 0-45 parts of copper, 0-20 parts of aluminum, 0-20 parts of silicon, 0-10 parts of iron, 0-10 parts of zinc, 0-5 parts ofsilver and 0-5 parts of palladium. The dental implant is in an amorphous metallic glass cylindrical rod shape with a diameter being 2-6mm and a length being 4-13mm, a tapping screw thread structure is arranged on the part located in a bone of the dental implant , the screw pitch is 0.7-2mm, a thread depth is 0.3-0.6mm, the thread section is triangular, a notch is formed in the bottom of the dental implant, the notch is located between a first thread and a third thread at the bottom. The zirconium-based amorphous metallic glass dental implant is good in breaking strength, good in biocompatibility and moderate in elastic modulus, has a 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...
