Abstract

Orthodontic treatment plan of bimaxillary protrusion is four first bicuspid extraction. This case report presents 22-year-old Thai male patient with protrusive upper and lower anterior teeth. The patient was diagnosed with skeletal Class I relationship and dental Class I malocclusion, convex facial profile and protrusive upper and lower lips. The upper right central incisor had previously treated and asymptomatic apical periodontitis with iatrogenic root perforation, resulting in a poor prognosis. The treatment involved fixed orthodontic appliances with the extraction of three first premolars and the upper right central incisor. The upper right lateral incisor was substituted for the extracted central incisor. Treatment outcomes demonstrated a stable occlusion, improved facial esthetics, This case report highlights the successful use of lateral incisor substitution as an alternative treatment approach for patients requiring upper central incisor extraction.
