Orthodontic bracket and manufacturing method thereof

Abstract

The invention discloses an orthodontic bracket for teeth and a manufacturing method thereof. The bracket includes a bracket body with a main archwire groove, and ligature wings are arranged on both sides of the main archwire groove in the bracket body. The feature is: an elastic reed is provided under the ligating wing on one side, a secondary archwire groove is formed between the reed and the ligating wing, and a gap between the head of the reed and the edge of the ligating wing There is a notch for the secondary archwire to slide into. The bracket of the present invention has double archwire grooves, and the auxiliary archwire grooves utilize the space below the ligature wings on the bracket body, wherein a reed is provided on the lower part of one ligature wing, and the gap between the ligature wing and the reed is The auxiliary arch wire groove is formed in the area, and the height of the bracket body is not increased, which makes the patient more comfortable and makes the bracket less likely to fall off. It is more convenient and reliable than the self-locking bracket with the main arch wire as self-locking; at the same time, in the later stage of orthodontics, due to the effect of double arch wires, orthodontics is faster and more efficient.

Description

technical field [0001] The invention relates to the technical field of dental orthodontics, in particular to a dental orthodontic bracket and a manufacturing method thereof. Background technique [0002] At present, in the process of orthodontic treatment of oral teeth, the orthodontic bracket is fixed on the tooth surface, and the arch wire passes through the arch wire slot (also known as the square wire slot) on the bracket, and is bound by a rubber ring or a steel wire. The arch wire is directly tied to the bracket ligation wing, and the correction force of the arch wire is transmitted to the teeth through the bracket, so that the teeth can move as expected, so as to achieve the purpose of correcting the teeth. [0003] In the early stage of bracket correction currently used, the ligation rubber ring or the ligation steel wire is ligated on the ligation wing of the bracket, and force is directly applied to the arch wire, which produces a large pressure on the arch wire an...

AI Technical Summary

Problems solved by technology

[0003] In the early stage of bracket correction currently used, the ligation rubber ring or the ligation steel wire is ligated on the ligation wing of the bracket, and force is directly applied to the arch wire, which produces a large pressure on the arch wire and hinders the normal movement of the arch wire, thus Affected orthodontic effect of teeth

At present, there are many kinds of self-locking brackets on the market, including two series of active type and passive type, but they are large in size, especially higher than ordinary brackets, and their structures are more complicated, difficult to manufacture, high in cost, and expensive
