Their main feature is that they do not require the elastic ligatures that attach them to the wire, which are necessary in other types of brackets. Instead, the design of self-ligating brackets incorporates a movable flap that secures the wire to the bracket and reduces friction. This makes the movement of the teeth faster, facilitates the orthodontist’s work, and shortens adjustment visits.

Furthermore, the absence of elastic bands makes them easier to clean and maintain, making the treatment more comfortable and faster.

Self-ligating brackets are a novel orthodontic technique that, with 20 years of history, has sparked debate about the effects of friction on the duration of orthodontic treatments. Their main novelty is a different binding system, visible in the design of the brackets.

Other types of orthodontics, such as those using metal or aesthetic brackets, have elastic bands that keep the arch attached to the brackets, guiding its movement. However, this movement occurs more slowly due to the friction that the band exerts on the wire.

The flap present on each bracket allows the wire to remain fixed without the need for elastic bands, making tooth movement easier and less painful.

Furthermore, the square design of these brackets and the unique fixation make their hygiene easier and adjustment sessions quicker, without the need to change ligatures.
