Fixed Appliance with Expansion Screw for the Treatment of Primary Anterior Crossbite

Abstract

Anterior crossbite occurring during the primary dentition stage needs immediate correction so that functional, aesthetic and skeletal complications may be avoided in the future. This article describes a fixed appliance with an expansion screw that was successfully used for the treatment of primary anterior crossbite. Crossbite correction was achieved in about six weeks. A detailed description with regard to fabrication of the appliance has also been discussed.
