Abstract
The treatment for intrusive dislocation is a clinical challenge and must be started soon after the intrusion injury. The affected tooth or teeth must be extruded by using light forces. This case report of traumatic intrusion of permanent central incisors aims to describe and discuss the process of repositioning the teeth in the dental arch. After a domestic accident, a 10-year-2-month-old boy suffered 11-mm intrusion of the maxillary central incisors along with enamel-dentin fracture and subluxation of the maxillary lateral incisors. Treatment started 2days after the incident with an orthodontic extrusion of the maxillary central incisors with a fixed edgewise standard appliance. Orthodontic arches were used, and the force vectors were directed to the desired locations for the repositioning of the teeth. The treatment for extrusion and stabilization of the maxillary central incisors lasted 5months and 22days. Orthodontic traction with a fixed appliance is an effective procedure for the extrusion of both permanent maxillary central incisors intruded after trauma. Correct diagnosis, a short period between the trauma and the beginning of treatment, and appropriate mechanics were determining factors for a successful treatment.
