Utility arches, originally designed by Ricketts as a part of his Bioprogressive therapy, are one of the most versatile auxiliary arch wires. They can be used for a wide variety of orthodontic tooth movements including protraction, retraction, intrusion and to hold teeth passively. They are also called as 2 × 4 appliances and can be used in both permanent and mixed dentitions. Their construction and applications are well illustrated with case reports.
