A method for bending an arch wire

Abstract

The invention relates to the technical field of orthodontics, and discloses an arch wire bending method. The arch wire bending method comprises the following steps: step 1: introducing a design outline drawing or design curve data of an arch wire into a cutting machine, and using the cutting machine to cut a groove on a thin plate according to the design outline drawing or the design curve data, specifically, the shape of the groove is consistent with the designed shape of the arch wire; step 2: clamping the arch wire to be bent into the groove; step 3: pressing at least one first pressing plate to be above the thin plate; step 4: placing the first pressing plate and the thin plate in a heating device for heating and heat preservation, and after the arch wire is formed, taking the first pressing plate and the thin plate out of the heating device; and step 5: removing the first pressing plate from the thin plate, taking the arch wire out of the groove, and performing the surface treatment on the arch wire. The arch wire bending method has the advantages of simple operation, high bending precision and low cost.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to an arch wire bending method. Background technique [0002] Orthodontic treatment is used by more and more beauty lovers for plastic surgery, not just for health needs. There are many types of aligners, but whether it is a digital labial aligner or a lingual aligner, due to the differences in the optimal dental arch shape and the teeth themselves of each patient, it needs to be bent according to the situation of different patients during the correction process. Individualized archwires can achieve the best correction effect. The various data expressed by the arch wire are crucial to the overall correction effect, so the bending accuracy of the individual arch wire is an important factor for the success of the correction. [0003] At present, the commonly used bow wire bending method is to be bent by a skilled craftsman or by a manipulator. Manual bending has the disadvanta...

AI Technical Summary

Problems solved by technology

Manual bending has the disadvantages of being difficult, time-consuming, and incapable of mass production

If it is bent by a manipulator, the manipulator equipment is expensive, the initial investment is large, and the technology is not mature, and the manipulator can only bend stainless steel and other steel wires with a small springback. For nickel-titanium wire and β-titanium wire, the springback is relatively high. It is difficult for the manipulator to bend the arch wire precisely

In addition, in the process of bending the arch wire, the manipulator is easy to strain the arch wire, causing damage to the internal structure of the metal, making the arch wire easy to break during the correction process, and it is still difficult for the manipulator to bend the arch wire that requires high smoothness. successfully bent out
