Abstract: Background Hyperdontia is a disorder of odontogenesis characterised by excess teeth. Many complications can be associated with supernumerary teeth, such as crowding, tooth displacement, diastema, deep caries, retention or impaction, delayed eruption or ectopic eruption of adjacent teeth, aesthetic problems, neuralgic manifestations, root resorption of adjacent teeth, and dentigerous cyst formation with significant bone destruction. Treatment of hyperdontia depends on the area and number of supernumerary teeth, and also on the presence of pathologic processes that can affect them and/or the teeth of the normal series that could be erupted, retained or impacted.
Case report The present case report describes the clinical management of two impacted supernumerary teeth, which impeded the eruption of the maxillary right central incisor in a paediatric patient. A multidisciplinary treatment approach was planned, including the surgical removal of the supernumerary teeth and the orthodontic correction of the unerupted permanent maxillary right central incisor. Combined surgical and orthodontic treatment resulted in an aesthetically pleasant and balanced occlusion. Thus, early multidisciplinary treatment is required for greater hard and soft tissue preservation.
