The finding of supernumerary teeth in the oral cavity is a common occurrence, and they are interesting because of their potential to lead to aesthetic and functional alterations. When they are present in the anterior area of the maxilla, they may cause complications, such as late tooth eruption or impaction of the central incisors. They affect from 0.5 to 3.8% of the population, with men being more affected.
This article describes two cases of impaction of the permanent maxillary left central incisor, due to the presence of a supernumerary tooth in the parasagittal area of the pre-maxilla, as well as the surgical and orthodontic procedures adopted.
