  • Orthodontic brackets also called brackets, are accessories commonly used in the treatment or correction of tooth positioning. To do so, the brackets are glued or fixed to the teeth and interact with orthodontic wires to provide movement of the dental arch.
  • Brackets A widely used type of bracket is the self-ligating bracket.
  • Self-ligating brackets are conceptually defined into two types, interactive brackets and passive brackets.
