Aim: To present a case with skeletal class II malocclusion and mandibular retrusion treated using Carriere Motion Appliance (CMA). Background: Management of class II malocclusion in adolescent patients by growth modulation is one of the most debated topics in orthodontics. Fixed functional appliances are generally used in the patients who are at the end of the postpubertal growth spurt. However, most of the fixed functional appliances are placed only after the initial alignment and leveling, which takes up considerable duration of time. The Carriere Motion 3D is an efficient and effective way of correcting the sagittal component of class II malocclusion within the first half year of treatment followed by comprehensive therapy using fixed appliances. Case description: A 15-year-old male patient reported with the chief compliant of forwardly placed upper front teeth and functional jaw retrusion. It was treated initially with CMA and class II elastics for mandibular advancement. Simultaneously, lower arch was bonded with MBT 0.022” prescription for alignment and leveling. After 6 months, class I molar and canine relationship was achieved before proceeding with full orthodontic treatment. After 12 months of fixed orthodontics, the treatment goals were achieved. Conclusion: Carriere Distalizer appears to be more comfortable, offer a more positive overall experience, and has fewer side effects. The changes were mainly dentoalveolar in nature, but there were some skeletal changes, particularly in the sagittal and vertical dimensions. Clinical significance: A significant forward displacement of the mandible was the principal element for successful correction of class II malocclusion. CMA provides the best results for class II management, enabling us to treat such cases with a nonextraction approach rather than contemplating extractions.
