Preparation method for medical false tooth

Abstract

The invention discloses a preparation method for a medical false tooth. According to the preparation method for the medical false tooth, the alloy material comprises the following components of 0.6% of Nb, 7% of Fe, 6.5% of Mo, 0.7% of Mn, 12% of Zr, 0.65% of Ge, 3.5% of Ga, 3% of Cr, 2% of Ca, 1.4% of In, 0.03% of C and the balance Ti. According to the preparation method for the medical false tooth, element powder or alloy powder of all elements with appropriate particle sizes is adopted, after the element powder or the alloy powder is mixed, the element powder or the alloy powder is sintered through injection molding, and accordingly the medical false tooth is obtained; the strength of the manufactured medical false tooth is much larger than that of a medical pure titanium material, the medical false tooth is friendly to the oral environment and low in density, and has good smelting and sintering machining properties; the mechanical properties of the medical false tooth are close to those of a real tooth, and the anti-fatigue property and the anti-corrosion property are good.

Description

technical field [0001] The invention belongs to the medical and health field, and in particular relates to a preparation method of a medical denture. Background technique [0002] With the development of modern medicine and materials science, medical prosthetics, artificial joints, bone fixators, dental implants, heart valve covers, etc. are used to manufacture medical devices, prostheses or artificial organs and auxiliary treatment equipment implanted in the human body. The application in the medical and health field is becoming more and more extensive. As this type of operation becomes more and more mature, the demand for artificial joints has increased significantly, and the above-mentioned components have made great progress in terms of biocompatibility, strength, plasticity, and corrosion resistance. At present, the medical alloys used in the medical field mainly include Ni-Cr series, Co series, Ti series, etc. Among them, the Ti-6Al-4V alloy of the Ti series is the mos...

Problems solved by technology

At present, the medical alloys used in the medical field mainly include Ni-Cr series, Co series, Ti series, etc. Among them, the Ti-6Al-4V alloy of the Ti series is the most widely used medical alloy, but it has been found in recent years that Ti- 6Al-4V alloy will precipitate a very small amount of vanadium and aluminum ions during use, and the precipitated vanadium ions are toxic and will cause adverse tissue reactions. Aluminum ions will cause human nervous disorders, reduce cell adaptability and other defects that are harmful to the human body At present, the main solution is to prevent the precipitation of toxic element ions such as vanadium and aluminum to a certain extent through surface coating and other treatment technologies, but this method increases the complexity of the processing procedure and increases the cost, and there will still be some Toxic elements such as vanadium and aluminum are precipitated, and the reliability cannot be guaranteed
