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

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

case_images: 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).

case_images: 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)).

case_images: 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).

case_images: 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).
