Description

Self-ligating orthodontic bracket The present invention relates to a self-ligating orthodontic bracket. Generally, orthodontic brackets are devices used to correct uneven teeth. Correction of teeth using these brackets is performed by bonding the brackets to the surfaces of the teeth, inserting orthodontic wires into the slots of each bracket bonded to the tooth surfaces, and securing the wires in the slots using fixing parts and binding components, such as elastic rings, configured on the brackets to prevent the wires from slipping out. In this state, the tension of the wires fixed in the bracket slots is adjusted in the desired direction to gradually correct the misaligned teeth over a long period. Therefore, since elastic rings must be wrapped around each bracket to secure the wire inserted into the bracket slot, the work is not only very cumbersome and difficult but also requires a significant amount of time and effort for the connection. As a means to solve this problem, there is a demand for self-ligating orthodontic brackets that allow for simple binding without the operator having to manually bind the wires inserted into the slots using elastic rings.
