Both direct and indirect traction to the miniscrew were used with derotation elasto- meric chains for enhanced control of the final crown and root position (Figs. 3 & 4a–c). The finishing phase was accomplished with braided multistrand stainless-steel 0.018 × 0.025 in. arch wires and intermaxillary elastics. An upper Hawley plate was used for retention after ap- pliance removal in the maxillary arch, and a man- dibular fixed retainer was bonded in the man- dibular anterior segment.
