case_images: Maxillary central incisors and canines were bonded and 0.016 niti arch-wire was ligated to prevent an anterior cross-bite from developing [Figure 3].
case_images: (a) Status of the dentition 6 months post-surgery, (b) Functional regulator-3 appliance delivered to maintain the expansion (5 mm) and to promote unimpeded maxillary growth, (c) Extraoral frontal view 6 months post-functional regulator-3 appliance therapy, (d) Extraoral profile view post-functional regulator-3 appliance therapy
