case_images: With severe extrusion of the maxillary molars, more severe on the left side, the maxillary midline deviated 2.0 mm to the right, and the mandibular deviated 1.0 mm to the left. (Figures 1 and 2). The cephalometric measurements and superimposition revealed a proclination of the maxillary incisors and the maintenance of a good profile line (Figure 9, Table 1).

case_images: In spite of the good evolution, there was a reduction in the vertical distance of the maxillary left posterior teeth in relation to the mini-implant, thus making it necessary to replace the buccal mini-implant with a miniplate (Figures 5(a)-5(c)). NiTi springs were also used for the anterior retraction and thus facilitated the correction of the Class II dental relation and the maxillary midline deviation (Figures 5(d)-5(f)).

case_images: Prior to the removal of the maxillary and mandibular fixed appliances, temporary acrylic crowns were affixed over the lower implants, to maintain the recovered vertical dimension (Figure 6).

case_images: Facially, her smile became symmetrical, balanced, and harmonious (Figure 7, facial). After the removal of the appliance, a fixed canine-to-canine retention (0.6 mm), was bonded, and a wraparound-type removable appliance were used for the full duration of a year, after which it was used for another year, but only at night during sleeping hours (Figures 7 and 8).

case_images: The panoramic radiograph shows that the maxillary left molars' alveolar bone level is in good shape, reasonable root parallelism, and implant-prosthetic rehabilitation in the mandibular arch (Figure 9). The cephalometric measurements and superimposition revealed a proclination of the maxillary incisors and the maintenance of a good profile line (Figure 9, Table 1).
