AI Technical Summary

Problems solved by technology

However, because it contains nickel, it may cause allergic reactions in patients
At the same time, the elastic modulus of NiTi alloy is very small, and its elastic deformation is very large when it works. Often the handle end has been rotated many times before the tip of the instrument can actually twist. Most of the elastic deformation is consumed in the length, so the doctor's The hand feeling becomes insensitive, and it is easy to cause misjudgment and twist the instrument into the tooth

Embodiment 1

[0044] Example 1: 1100g of pure molybdenum powder, 500g of pure zirconium wire, 400g of pure tin wire, and 8000g of titanium sponge.

Embodiment 2

[0045] Example 2: 1000g of pure molybdenum powder, 450g of pure zirconium wire, 525g of pure tin wire, and 8025g of titanium sponge.

Embodiment 3

[0046] Example 3: 1300g of pure molybdenum powder, 750g of pure zirconium wire, 375g of pure tin wire, and 7575g of titanium sponge.

[0047] 1. Smelting of materials

[0048] Using the vacuum consumable electrode arc melting method, the raw materials of pure molybdenum powder, pure zirconium wire, pure tin wire and sponge titanium are pressed into consumable electrodes. The melting voltage ranges from 20V to 50V, the current ranges from 1000A to 3000A, and the vacuum degree is not lower than 10 -2 Pa, to obtain the ingot billet, such as Figure 11 shown.

[0049] 2. Processing of billets

[0050] Remove the riser from the ingot, peel off the surface on a lathe to remove defects such as scale and subcutaneous pores, and polish the billet to remove defects such as folds, heavy skin, cracks, etc., and then hold it at 950°C for 2 hours to forge it into a 70mm×70mm square billet , and then gradually forged into a 30mm×30mm square billet, and then rolled into a circle. Rotate ...

Abstract

A root-canal therapeutic device is composed of a bare needle made of TiMoZrSn alloy containing Mo (10.0-13.0 Wt %), Zr (4.5-7.5), Sn (3.75-5.25) and Ti (rest), and a handle. Its advantages are no Ni poisoning, low elastic modulum and rigidity, and high cutting effect.

Description

technical field [0001] The invention relates to a root canal preparation instrument for oral cavity treatment, in particular to a TiMoZrSn alloy root canal instrument. Background technique [0002] Root canal treatment of affected teeth is the most effective treatment for pulp disease and periapical disease. By cleaning, shaping and filling the root canal, the problem of tooth preservation with infected root canal can be solved. Root canal instruments are one of the important root canal instruments used in root canal treatment to shape or extract the residual pulp in the root canal and remove debris. The structure of the root canal system is more complicated due to the different degrees of caries damage, root tip involvement, pulp cavity size, root canal thickness, length and curvature of the affected teeth, and root canal treatment preparation instruments are often used during treatment. Bending with root canal conditions. [0003] Most root canal instruments currently in...
