Abstract:
Background: Intrusion is an injury considered one of the most severe luxation injuries to affect permanent teeth, a difficult injury to treat and is associated with several complications.
Aim: Presentation of management outcome of an intrusive luxation of immature permanent incisor. The case: A seven years old girl who presented with severe intrusion of an immature maxillary permanent right central incisor. Management and outcome: Initial management of waiting for spontaneous re-eruption resulted into partial re-eruption of the intruded tooth. No further re-eruption six months after injury compared to what was present at the seventh week. Orthodontic extrusion was done using a Nance appliance followed by Orthodontic brackets six weeks later. These resulted into complete re-eruption and proper alignment of the intruded tooth.
Conclusion: Orthodontic repositioning of an intruded maxillary permanent incisor can be successfully achieved using a modified Nance appliance even when commenced at a late time after un-progressive passive re-eruption.
