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

1, the protection of soft tissue is different: the self-locking bracket can effectively avoid the damage to soft tissue and is safer to wear. However, ordinary bracket correction technology needs to fix some small steel wires and arch wires with each other, so it is easy to cause soft tissue injury in this process.

2. The influence of ligature wires is different: there are ligature wires around ordinary brackets, but there are no ligature wires around self-locking brackets. Self-locking brackets use slight light force to move teeth because of low friction, so users are more comfortable to wear and can reduce discomfort and pain.

3. Different characteristics: The shape design of the bracket is mainly to strengthen the adhesion with the tooth surface. The shape of the base surface of the bracket is suitable for the shape of the lip and cheek surface of each tooth, and there is a metal mesh or etched bottom plate, so that the bracket is firmly adhered to the tooth surface by adhesive. Self-locking bracket correction technology can greatly reduce the friction resistance between steel wire and bracket.

Precautions:

1. Because the friction between the archwire and the bracket is extremely low, the archwire is easy to slide in the groove, so an anti-skid device must be added to the archwire. The principle is not to hinder the teeth from sliding or decongesting.

2. Even without tooth extraction, the dental arch is prone to cracks, especially in the case of tooth extraction. Therefore, after the gap is closed in the stainless steel wire stage, attention should be paid to maintaining contact between teeth.

3. Try to avoid using devices that may limit the width adjustment of posterior dental arch, such as maxillary TPA, Nance arch, rapid arch expansion device, extraoral arch, etc.
