The intraoral clinical examination revealed the complete intrusion of the permanent maxillary left lateral incisor, as well as a gingival laceration (Figure 1).

The radiographic examination revealed that the left maxillary lateral incisor was completely and severely intruded (Figure 2).

The traumatized lateral incisor was splinted from the central incisor to the ipsilateral first premolar using 0.5 mm stainless-steel multistranded flexible orthodontic wire and an acid etch-composite resin technique (Figure 3).

At the same visit, the radiographic examination revealed external root resorption of the adjacent central incisor as a late complication of the luxation injury (Figure 4(a)). In the present case, the teeth were stable and the patient was completely asymptomatic 12 months postoperatively (Figure 4(b)). Also 24-month radiographic examination showed that there were no signs to indicate resorption or infection (Figure 4(c)).

The maxillary lateral and central incisors were found to have remained in position and there were no signs of periapical lesions or resorption (Figure 5).

Also, the clinical findings demonstrated that the chosen clinical protocol was successful as both teeth remained asymptomatic; there was no gingival inflammation or mobility (Figure 6).
