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”
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. View slide
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 Use the Hemostat to place the elastic ties and the orthodontic scaler to remove them
