She also presented with the maxillary posterior right segment in buccal crossbite (tooth no. 12, 13, and 15) (Fig. 1A) and the absence of 22. The permanent maxillary right lateral incisor (tooth no. 12) was peg-shaped (Fig. 1B and C).

A quad helix appliance was fabricated and cemented (Fig. 2A). Placement of a fixed orthodontic treatment was done to correct the anterior crossbite and to align, level, and manage the spacing of the upper arch (Fig. 2B). To gain the required space for the permanent maxillary right lateral incisor (tooth no. 12), the operator incorporated an open coil spring between teeth permanent maxillary left central incisor and canine (teeth no. 21-23) and permanent maxillary right central incisor and canine (teeth no. 11-13) to gain the required space (Fig. 2B).

The operator used the direct freehand composite method to restore the maxillary right lateral incisor (Fig. 3A). The crown prosthesis was fabricated with HIPC (Bredent, Germany) and cemented with zinc phosphate-luting cement (Fig. 3B).
