Rho Loop: A Novel Approach for Correcting Unfavorably Rotated Bilateral Teeth

Abstract

Rectangular loops have been advocated for correcting severely malaligned teeth due to their simplicity and range of activation. This article describes a novel design of two rectangular loops used for correcting the bilaterally malaligned teeth without using the molars as anchor tooth. The present Rho loop offers an alternative for improving the position and angulation of severely malaligned bilateral teeth.
