Introduction to metal self-ligating bracket

Self-ligating bracket is a kind of orthodontic device made of metal or ceramic materials in orthodontic treatment. It is fixed on the tooth surface with special adhesive to accommodate and fix the orthodontic steel wire and convey the orthodontic force to the teeth to achieve the purpose of orthodontic.

Metal brackets need to be fixed together with thin steel wire or rubber band and correction steel wire. During correction, moving teeth needs to overcome the friction resistance between steel wire and bracket. The greater the friction, the greater the correction force, the slower the moving speed and the longer the correction time. The metal self-ligating bracket directly locks the orthodontic steel wire in the groove of the bracket, avoiding the binding of the orthodontic steel wire by the ligation steel wire or rubber band. There is a locking device more than the metal bracket, which greatly reduces the friction resistance between the steel wire and the bracket.

Metal self-ligating brackets and ceramic self-ligating brackets are the most popular buccal fixed brackets. The color of ceramic self-ligating is very similar to that of teeth, which is more beautiful than metal self-ligating brackets, and the price is also more acceptable.
