A Mandibular Hawley Appliance is most often comprised of stainless steel clips (clasps) on the posterior teeth, a wire (labial bow) across the front teeth, and a polished acrylic framework along the inside of the mouth, reinforced with stainless steel wires.
The Mandibular Hawley Appliance is used to maintain a previous orthodontic result or to simply prevent undesirable movement of the teeth. Typically, patients wear a retainer full-time for three months following active orthodontic treatment. Thereafter patients wear retainers nightly and at home for nine additional months. Retainers will be worn during sleep hours indefinitely after the first year of treatment.
