Radiographic assessment (XGenus, De Gotzen SRL, Varese, Italy) confirmed the extrusive luxation of tooth #21, possible alveolar fracture, and incomplete root development of all the maxillary incisors (Figure 1(a)).

The splint was removed after four weeks according to the guidelines for the management of extrusive luxation, and the incisal adjustment was performed (Figure 2(a)). Despite some minor radiolucency caused by a subtle vertical bone defect detectable along the distal portion of the root, clinical and radiographic features of the left maxillary central incisor seemed stable (Figures 2(c) and 3(c)), and normal mobility and percussion sound were recorded; a modest degree of infraocclusion was also evident.

The third follow-up after 6 weeks revealed external root resorption and vertical bone loss on radiographic examination of tooth #21 (Figure 3(a)); therefore, endodontic treatment was undertaken. Tulsa, OK) (Figure 3(b)).
