    Impacted teeth are those which remain enclosed within the jaws maintaining the integrity of their physiological peri coronary sac during the arrival of their normal eruption. It is presented the case of a 10 -year -old- female patient, who attended to Orthodontics due to a clinical absence of the upper right permanent incisor. The patient presented Angle Class III occlusion, a protuberance of 1 mm exceeding 1 mm and 2/3 of the crown, cross bite in 21, 22, 23 and transposition between 12 and 13. The X-ray examination evidenced an inverted tooth with incisal edge to the base of the nostrils, and a slight flattening on the floor of the nostril in the same side. The orthodontic treatment was performed to uncross the bite and place the 12 and 13 into their proper position. She was inter-consulted with the Maxillofacial Surgery Department, where she was surgically treated and a surgical link was made to bring the tooth to its normal position. A year after the surgery the tooth is located in a normal position and the space is maintained by means of orthodontic appliances.Se denomina dientes retenidos a aquellos que, una vez llegada la 茅poca normal de su erupci贸n, quedan encerrados dentro de los maxilares manteniendo la integridad de su saco pericoronario fisiol贸gico.
