Surgical approach to malformation of maxillary central incisor following trauma to its predecessor. Two case reports.

In the case reports, two different approaches have been described to treat the developmental disturbances in the maxillary central incisors due to trauma to its predecessor. The treatment plan was chosen according to the type and severity of the malformations, the exact location and the morphology of the involved teeth. In the first case, the disimpaction of the maxillary right central incisor was achieved with the combined of surgical and orthodontic therapy, that was planned in two consecutive stages. In the second case the severe root angulation and the failure of the previous orthodontic traction made impossible the repositioning of the upper right central incisor, which was surgical removed.
