Orthodontic extrusion of a traumatically intruded permanent incisor: a case report with a 5-year follow up

Abstract

This report presents a case of intrusive luxation of the immature left maxillary central incisor in an 8-year-old girl. Initially, it was decided to allow the intruded tooth to spontaneous re-erupt because it had open apices. After 12 weeks of monitoring for spontaneous re-eruption, there was no clinical evidence of its occurrence. Therefore, orthodontic extrusion was initiated. The intruded tooth was repositioned with a fixed multibracketed appliance. Twenty weeks after the beginning of orthodontic extrusion, the position of the intruded maxillary central incisor was restored to its original position before its displacement occurred. After 5 years, no clinical or radiographic pathology was detected and obliteration of the pulp canal of the intruded tooth was observed radiographically.
