Orthodontic treatment of a crowding case using segmental arch technique: A case report

Abstract

A 14-year-old female presented with ectopically erupted upper and lower canines and Class I molar relation. First premolar extraction was planned to correct ectopic position of canines. Segmental titanium molybdenum alloy T-loop was used to retract the canines into an ideal position in the upper arch, and Mulligan's bypass arch was used in the lower arch. Post-treatment results showed a correction of ectopically erupted canines, bilateral Class I molar relation maintained, and inclination of incisors improved. At the end of treatment, the patient showed pleased smile with improved smile arc.
