What is the principle of orthodontic technique with self-ligating brackets?

Self-locking orthodontic bracket refers to a device which is made of metal or ceramic and fixed on the surface of teeth with special adhesive in orthodontic treatment. It is used to contain and fix orthodontic wire and transmit orthodontic force to teeth, so as to achieve the purpose of orthodontics.

Self-locking bracket correction technology is a new technology in recent years, which has brought revolutionary changes to fixed orthodontic technology. So that pincushion distortion is more convenient. Its main advantage is that it can greatly reduce the friction resistance between the steel wire and the bracket. Because it adds a door to the bracket, it can directly lock the orthodontic wire in the groove of the bracket, eliminating the constraint of ligating wire or rubber band on the orthodontic wire.

Traditional orthodontic brackets need to be fixed with thin steel wires or rubber bands and correction wires, which is a routine practice, and it is precisely these ligation wires or elastic rubber bands that will delay the correction treatment. Because the orthodontic treatment of moving teeth needs to overcome the friction resistance between steel wire and bracket, the greater the friction, the greater the corrective force, the slower the moving speed and the longer the corrective time.

Compared with the traditional orthodontic technology, the locking bracket has one more locking device than the traditional bracket, just like adding a door to the bracket, which can directly lock the orthodontic steel wire in the groove of the bracket, avoid the restraint of the ligating steel wire or rubber band on the orthodontic steel wire, greatly reduce the friction resistance between the steel wire and the bracket, reduce the stress on the teeth, speed up the tooth movement and effectively shorten the whole treatment time.
