Bilateral Maxillary Central Incisor Impaction associated with Developing Supernumerary Premolars in the Mandibular Arch

Abstract

Impaction of maxillary permanent incisor is not a frequent case in dental practice, but its treatment is challenging because of its importance to facial esthetics. Various local causes responsible for impaction, such as odontoma, supernumerary teeth and space loss supernumerary teeth are the main cause of impaction of upper incisor. We report a case of 15-year-old girl with bilaterally impacted supernumeraries in the premaxilla region associated with asymptomatic impacted developing supernumerary premolars in the mandibular arch. The supernumeraries of premaxilla region impeded the eruption of the permanent maxillary central incisors. The impacted supernumerary tooth was surgically removed and brackets bonded to the central incisors to apply orthodontic extrusive force which brought the central incisors down to their proper position in the dental arch.
