Abstract

The invention discloses a titanium-niobium-zirconium alloy dental implant with high strength, low elasticity modulus and no toxicity and particularly relates to the field of medical materials. The main material used in the alloy dental implant is Ti-13Nb-13Zr alloy. A method for preparing the alloy dental implant comprises the following steps: S1, grinding powder, namely rotating and spinning outa prepared Ti-13Nb-13Zr alloy with plasma laser under argon protection to obtain spherical powder having a diameter of 10-60 microns, and performing vacuum packaging for later use; and S2, processingthe Ti-13Nb-13Zr alloy powder ground in the step S1 by utilizing a metal additive manufacturing process according to an implant appearance preset by a computer. The titanium-niobium-zirconium alloy dental implant is processed by a metal additive manufacturing (selective laser melting) process by adopting the Ti-13Nb-13Zr alloy, has the characteristics of high strength, low elasticity modulus and no toxicity and can meet daily use requirement of dental implants.

Description

technical field [0001] The invention relates to the technical field of medical materials, more specifically, the invention relates to a high-strength, low elastic modulus, non-toxic titanium-niobium-zirconium alloy dental implant. Background technique [0002] Dental implants are an important part of dental implants. Dental implants form long-term stable osseointegration with the alveolar bone in the edentulous area, which is an important guarantee for the long-term restoration effect of dental implants. [0003] At present, mainstream dental implants are made of pure titanium (brand TA1-TA4) or Ti-6Al-4V (brand TC4), which has the following limitations, which will affect the long-term stability of osseointegration: [0004] The brittleness of pure titanium is high, and it is easy to break under excessive external force, and the mechanical strength cannot meet the needs of long-term occlusal force of the implant; [0005] The elastic modulus of pure titanium and Ti-6Al-4V i...
