Summary

Introduction

Utility arches were introduced by Dr Robert Ricketts in the late 1950.The utility arch is one of the most versatile auxiliary arch wires that can be used in various stages of orthodontic treatment in either mixed or permanent dentition. Contemporary, fullbanded edgewise orthodontic approaches have assumed that the most efficient method of effecting rotations and leveling the deep curve of Spee in the initial phase of treatment is through the utilization of a series of light, continuous round arches.[1] Utility arches originally developed to counteract the tipping occurring in the buccal segments in the extraction cases by utilizing the so called immutable lower anteriors as anchor unit to hold molar and second premolar uprightning during retraction.[2]. Construction-The Utility arch is a continuous arch wire that extends across both buccal segments, but made of different wires for different purposes and based on which arch it is used in. It encompasses only six teeth i.e. two permanent molars and four incisors so it is called as 2×4 appliance.
