What is the difference between self-locking brackets and ordinary brackets? Which is better?

Both have their own characteristics. The main difference is that they are different in nature, principle of action and characteristics, as follows:

First, the nature is different.

1, self-locking bracket

Self-locking orthodontic bracket refers to a device made of metal or ceramic and fixed on the surface of teeth with special adhesive during orthodontic treatment.

2. Bracket

Bracket is an important part of fixed orthodontics, which is directly bonded to the crown surface by adhesive, and archwires exert various types of orthodontic forces on teeth through brackets.

Second, the principle of action is different

1, self-locking bracket

It is used to accommodate and fix orthodontic steel wire and transmit orthodontic force to teeth, so as to achieve the purpose of orthodontics.

2. Bracket

Made of stainless steel, bioceramics or composite resin, its main function is to fix the arch wire, so that the arch wire can play a better role and transmit orthodontic force, thus controlling the three-dimensional movement of teeth and achieving the purpose of orthodontic treatment. Third, the characteristics are different.

1, self-locking bracket

Compared with the traditional bracket, the self-locking bracket has an additional locking device, which can directly lock the orthodontic steel wire in the groove of the bracket, thus eliminating the restraint of the ligating steel wire or rubber band on the orthodontic steel wire, greatly reducing the friction resistance between the steel wire and the bracket, reducing the stress on the teeth, accelerating the tooth movement speed and effectively shortening the whole treatment time.

2. Bracket

The usual practice is to fix the correction lines together with thin steel wires or rubber bands, and it is these ligatures 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.
