Abstract:
An impacted tooth is a tooth that cannot erupt normally when its eruption is blocked or it is erupted in the wrong direction and posi-tion. The most commonly impacted teeth is the third molar, while in the anterior region, the most common is the maxillary canine, followed by the maxillary central incisor and the maxillary lateral incisor. In recent years, the treatment of impacted maxillary incisors often uses open and closed eruption techniques with traction. Although most of the prognosis is good, traction difficulties, root resorption and alveolar bone loss are often encountered in the case of root dilacerations. This article reviews the progresses in the treatment of impacted maxillary incisors.
