Problems solved by technology

[0005] At present, the orthodontic production industry is making great efforts to research and develop this kind of orthodontic arch wire product with gradual correction force value, but no breakthrough has been made. Now only one foreign company has successfully developed it, but due to the high cost, it has not been developed yet. It has been vigorously promoted and used, but there are no related products and reports in China

specific Embodiment approach 1

[0022] The gradient orthodontic force value orthodontic arch wire graded aging heat treatment molding process of the present invention is carried out according to the following steps:

[0023] 1. The upper mold, closely arrange the nickel-titanium round wires of Φ0.41 on the device of the present invention, and the distance of the wire arrangement is 0.3;

[0024] 2. Graded aging heat treatment, the temperature of the salt bath furnace is set to 540°C, and the mold and the wire are put together as figure 1 The anterior part of the area shown in area 1 is first immersed in the salt bath furnace with the front teeth facing down, and the overall decline is at a constant speed of 5mm / min. When the mold is half immersed in the salt bath, it stops falling. After 15 minutes of static heat preservation, the salt bath is quickly taken out, and after 5 minutes of air cooling Rotate the mold 180° and carry out the other half according to the above method. After completion, take out the ...

specific Embodiment approach 2

[0026] The difference between this embodiment and Embodiment 1 is that the graded aging heat treatment described in step 2 is to quickly immerse the orthodontic arch wire 1 area in the salt bath furnace to the centerline of the mold, and then heat it for 20 minutes at a rate of 5 mm / min. Elevate the mold at a constant speed at a constant speed, rotate 180° after being out of the oven for 5 minutes and then perform the above steps, and the rest of the steps are the same as in Embodiment 1.

specific Embodiment approach 3

[0027] The difference between this embodiment and Embodiment 1 is that the staged aging heat treatment in step 2 is a stepwise descending method, such as figure 1 The quick immersion is divided into three stages as shown, the 1st area is quickly immersed and then kept for 7 minutes, the 2nd area is soaked and then kept for 7 minutes, the 3rd area is immersed for 10 minutes, and the air is cooled after being out of the oven. The rest of the steps are the same as the first embodiment.

Abstract

The invention relates to an orthodontic arch wire with gradually changing orthodontic force value and its forming process and device. This kind of orthodontic arch wire gradually changes the orthodontic force value and elastic modulus from the front teeth to the posterior teeth, so that it can provide more reasonable orthodontic force values ​​for different teeth and different patients, and reduces the impact of the orthodontic force on the periodontal ligament. tissue damage. The present invention realizes the gradual change of the orthodontic force value of different parts on a single orthodontic arch wire by changing the cross-sectional shape of different parts of the orthodontic arch wire and adjusting the value of the orthodontic force by means of aging heat treatment.

Description

technical field [0001] The invention relates to a dental arch wire for oral orthodontics and its molding process and device. Background technique [0002] The role of orthodontic arch wire in the field of orthodontic treatment is self-evident. Orthodontic arch wire with brackets (including metal brackets, ceramic brackets, etc.), buccal tubes, belt rings and other products can complete most of the In orthodontic treatment, the function of the orthodontic arch wire is to provide a continuous force value to the teeth during the orthodontic process to complete the movement of the teeth. Orthodontic arch wires can be divided into nickel-titanium orthodontic arch wires, stainless steel orthodontic arch wires, and β-titanium orthodontic arch wires according to their performance. Traditional orthodontic arch wires can no longer fully meet the requirements of the market, so many products of the times have emerged, such as invisible arch wires and colored arch wires. [0003] At th...
