Self-ligating bracket

Abstract

The invention relates to the field of orthodontic technology, and discloses a self-ligating bracket. The self-ligating bracket comprises a bracket body and a bracket cover, and a depressed arch wire slot which is formed on the upper surface of the bracket body for penetrating the bracket body. One side of the bracket cover is connected to the bracket body by a rotating shaft and is covered on the arch wire slot, and the other side of the bracket cover which is opposite to the rotating shaft is connected to the bracket body by a spacing lock for locking; wherein the spacing lock comprises a lock bolt, a lock slot which is matched with the lock bolt, and a locking mechanism which enables the lock bolt to get in and out of the lock slot. Compared with the prior art, a turning cover type locking mode of the bracket is used, so that the bracket is advantageous in that clinic operation is more convenient, patients are more comfortable, torque control is additionally enhanced, etc. The turning cover type self-ligating bracket has the possibility of mass production due to the simple structure.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a self-locking bracket. Background technique [0002] In orthodontic treatment, the most important treatment method is fixed orthodontics. The fixed appliance system mainly consists of arch wires and orthodontic brackets. The brackets are bonded to the surface of the teeth with orthodontic adhesives, accommodate and fix the archwires, transmit the orthodontic force generated by the archwires to the teeth, and make the teeth arrange and move along the archwires, so as to achieve the purpose of orthodontics. [0003] Traditional orthodontic brackets require ligatures (usually thin wires or rubber bands) to secure the archwires. But the traditional ligation method will delay the course of corrective treatment. This is because during orthodontic treatment, the movement of the teeth needs to overcome the frictional resistance between the arch wire and the bracket. The greater ...

Problems solved by technology

However, on a miniature object with a size of about 2mm, the size of the elastic structure for placing the elastic lock is usually no more than 0.3mm, and the size of these elastic structures is even smaller, so the locking of the elastic lock cannot be reliably completed at all. Task

Therefore, the reliability and sensitivity of these existing clamshell self-ligating bracket designs cannot meet the practical requirements
