Introduction: This case study demonstrates the skeletal and dental changes achieved using the Removable Osseo-Restore Appliance^TM (RORA) in an 8-year-old male with an early Class III malocclusion.

Aim: To evaluate the effectiveness of the RORA appliance in correcting the Class III malocclusion.

Methods: The RORA appliance is a removable maxillary device worn full time, including while eating. The device features two sagittal screws that are turned twice a week until 5 - 7 mm of separation is achieved. The patient undergoes evaluation appointments every four weeks. Cephalometric tracings were taken before and after treatment and compared to assess positive skeletal changes, facial growth, and anterior crossbite correction.

Results: The cephalometric comparisons revealed positive skeletal changes and correction of the anterior crossbite. Furthermore, the treatment produced different effects than those typically achieved with facemask treatment.

Conclusion: The RORA appliance was effective in the early treatment of a Class III malocclusion.
