Irreversible ectopic eruption of maxillary first permanent molars may lead to crowded permanent dentition when it is overlooked. The situation usually requires active treatment. In the presented irreversible ectopic eruption cases, distalization and uprighting of maxillary first permanent molars were achieved using removable orthodontic appliances.
