Abstract

The invention relates to a titanium-based amorphous metal glass dental implant and a preparation method thereof, comprising: 30-75 parts of titanium, 0-25 parts of zirconium, 0-45 parts of copper, 0-20 parts of silicon, and iron 0-10, 0-10 parts of zinc, 0-5 parts of silver, 0-15 parts of palladium, the diameter of the dental implant is 2-6mm, and the length is 4-13mm; the part of the dental implant located in the bone has a self-tapping thread The structure has a pitch of 0.7-2mm, a thread depth of 0.3-0.6mm, and the cross-section of the thread is triangular. 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 titanium-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] 1 The strength of the material is low, the diameter of the implant is large, and the requirements for the three-dimensional bone mass of the implanted area are relatively high. When the amount of bone in the implant area is insufficient, bone augmentation technology must be used to meet the requirements of implant placement. However, bone augmentation surgery will increase surgical trauma and osseointegration cycle, increase the difficulty of surgery and the incidence of postoperative infection. [0004] 2 The modulus of elasticity of the material is much higher than that of cortical bone. Excessive stress is concentrated on the implant neck, wh...
