Embodiment 1

[0068] The amorphous alloy endodontic file manufactured in this embodiment specifically uses a ZrCuAlPd amorphous alloy ingot to produce the endodontic file.

[0069] The manufacturing of the endodontic file for endodontic surgery is performed under a vacuum of 10 -3 Under the protection of Pa under the vacuum state, the raw material alloy ingot is used to form the endodontic file embryo body by suction casting, and then to be twisted and cooled at the supercooled liquid phase temperature. The specific steps include the following steps:

[0070] a) Ingredients: Calculate the required raw material components according to the required amorphous alloy material components, and accurately weigh the raw materials whose component purity is above 99.9%;

[0071] b) Feeding: Put raw materials into the vacuum die casting machine (vacuum degree is 10 -3 Pa) in the feeding device, and added to the melting device by the feeding device;

[0072] c) Melting: The raw materials are melted by induction ...

Abstract

The invention provides an amorphous alloy dental pulp file and a manufacture method thereof. Compared with the traditional dental pulp file prepared from a titanium-nickel memory alloy, the novel dental pulp file has excellent properties such as high strength, high hardness, high elasticity, high surface smoothness, high fatigue strength and the like as well as corrosion resistance; meanwhile, the manufacture method of the dental pulp file is simple, machining can be performed at a lower temperature, and the dental pulp file can be manufactured with methods such as twisting, rolling, weaving, impressing and the like.

Description

Technical field [0001] The present invention relates to the field of medical instruments, in particular to a novel endodontic file and a manufacturing method thereof. Background technique [0002] The endodontic file is a commonly used medical product in modern endodontic medicine. It is mainly used to remove damaged gums so that the tubular space can be cleaned and filled with biocompatible materials. Since the endodontic file needs to be rotated in the tooth and drilled out of the tubular space, it is required to have high strength, high elasticity, corrosion resistance and other properties. [0003] Currently, titanium-nickel memory alloy is mainly used as the original material for endodontic files. Although this kind of endodontic file has higher strength and higher elasticity, there are still reports that titanium-nickel endodontic files will break, which not only increases the risk of surgery, but also makes this kind of tooth The use of endodontic files is restricted, whic...
