Early treatment of Class III malocclusion provides an improvement in facial appearance and corrects the reverse bite. Orthopedic protraction of maxilla is considered best approach in growing Class III patients with maxillary deficiency. Present case report describes the management of a growing 10-year-old boy with skeletal Class III malocclusion using facemask therapy (Phase 1) followed by fixed orthodontic treatment (Phase 2) based upon cephalometric prognostic findings of growth treatment response vector (GTRV). With the successful orthopedic phase of maxillary protraction with facemask therapy for 7 months of period, a significant improvement in profile had been achieved along with the correction in reverse overjet. This was followed by retention with chin cup therapy for a period of 20 months. After a period of 20 months retention, a fixed orthodontic treatment was started with the objective to achieve stable functional occlusion. After 11 months of treatment with fixed appliance therapy a stable functional occlusion was achieved. The patient was placed on Hawleys retainer in maxillary arch and bonded fixed spiral wire (FSW) retainer in mandibular arch. Successful management of growing Class III patient was done using facemask and fixed orthodontic therapy based upon cephalometric prognostic findings of growth treatment response vector (GTRV).
