  • Arch wires, Elastic ties and Separators
  • Arch wire
    It serves as a pattern from which the dental arch will take its shape.
    Types of arch wires are:
    • Nickel titanium: very flexible, used during the initial stage of tooth movement.
    • Stainless steel: stiffer and stronger, applies greater force and better stability to control teeth. “the working wire” View slide
    • Beta titanium: combination of strenght and flexibility. Used when many bands have to be placed.
  • Shapes of arch wires
    Round: used during initial and intermediate stages
    Square or rectangular: used during the final stages of treatment to position crown and root in the correct maxillary and mandibular relationship.

  • Separators
    Used when the interproximal contacts are too tight in order to separate the teeth and then be able to seat the bands.
    Use separating pliers to place separators

  • Elastic Ties
    Once the arch wire has been positioned it must be tied into place, the elastic ties stretch around the bracket to hold the arch wire in place. They come in different colors
