How do bonded brackets initiate tooth movement?

Bonded brackets facilitate tooth movement by allowing forces from the arch wire to be effectively transmitted to the tooth. The mechanism relies on the brackets being securely bonded to the surface of each tooth, thus creating a stable connection between the tooth and the arch wire. When the arch wire applies force, the brackets serve as anchors that transfer this force directly to the individual teeth. This transfer of force enables controlled movement, which is essential for achieving the desired orthodontic outcomes.

The effectiveness of this system hinges on the ability of the brackets to maintain their position on the enamel while facilitating the movement prompted by the arch wire. In orthodontics, successful tooth movement depends on the precision with which forces are applied, and bonded brackets are key in ensuring those forces act specifically and consistently on the teeth.
