Orthodontic Treatment of Aesthetically Unpleasing Severe Crowding and Anterior Crossbite

Abstract

This case report describes the treatment of a 25-year-old lady with severe crowding in the maxillary and mandibular anterior  segments and anterior crossbite of the maxillary incisors. Treatment consisted of 4-unit extraction of the first premolars and use of open coil springs to open up spaces for the palatally excluded maxillary lateral incisors during fixed orthodontic  appliance therapy. The result of the treatment showed improved facial profile, correction of overjet, and overbite. Therefore, extractions are still helpful in improving treatment outcomes in cases of severe crowding.
