Correction of Supernumerary Tooth‐Associated Anterior Crossbite in Mixed Dentition Using a 2 × 4 Appliance

Year: 2026

Type: erratum

Abstract: Anterior crossbite is a common tooth alignment discrepancy seen among the paediatric population especially during the mixed dentition stage. There are many causes of anterior crossbite, and the presence of supernumerary tooth/teeth is one of them. Early interceptive intervention is essential to avoid the need for more complex orthodontic treatment later. This case report describes the management of a 10-year-old child who presented with anterior crossbite involving Teeth 21 and 31, leading to gingival recession of Tooth 31. The crossbite malocclusion was associated with a supernumerary tooth in the upper incisor region. Extraction of the supernumerary tooth was performed, and correction of the anterior crossbite was commenced with a 2 × 4 appliance. Adequate stability with a positive overjet was observed at the 6-month review. The 2 × 4 orthodontic appliance may be considered a treatment option for correcting anterior crossbite in patients with poor compliance with removable appliance therapy.
