Lower Spring Retainer This removable retainer is occasionally used to align lower incisors that have relapsed following orthodontic treatment.
	Lower Hawley Retainer This removable retainer is occasionally used to maintain the alignment of the lower teeth following orthodontic treatment.
	Lower Bonded Retainer This retainer is routinely used to maintain alignment of the lower teeth following orthodontic treatment. It is invisible since it is bonded to the inside surfaces of the lower canines.
	Upper Hawley Retainer This removable retainer is routinely used to maintain the alignment of the upper teeth following orthodontic treatment.
	Upper Clear Retainer This removable retainer is made of clear plastic and is occasionally used as a temporary retainer. It is generally followed up with a conventional upper Hawley retainer.
	Lower Lingual Holding Arch This appliance is typically used to maintain the alignment of the lower incisors following an initial phase of orthodontic treatment. It also holds space for the lower permanent teeth to erupt.
	Upper Nance Arch This appliance is used to hold space in the upper arch by maintaining the position of the six-year molars. This is frequently used following early loss of the baby second molars.
	Maxillary Expander This appliance is most often used in growing patients that have narrow palates. It is bonded to the six-year molars and is activated by the patient. This controlled activation gradually widens the upper jaw with little discomfort.
	Headgear Growing patients with large overbites often require headgear to correct an excessive overbite. The headgear attaches to bands that are cemented on the upper six-year molars. If worn well, a significant reduction in overbite may be seen during treatment.
	Archwires These are the wires that are replaced or adjusted at each appointment during treatment. As they lay in the braces, they gradually align the teeth.
