Objective: To report the non‑surgical correction of skeletal Class III in an 11‑year‑old boy using clockwise mandibular repositioning in combination with GEAW (Gummetal Edgewise Archwire) mechanics.

Materials and Methods: Posterior bite‑raising was used to unlock the mandible and register an edge‑to‑edge incisal position for cephalometric analysis (Ricketts). Leveling/alignment were performed with nickel‑titanium archwires, followed by space regaining with coils and multiloop mechanics. Rectangular Gummetal 16×22 then 17×22 archwires delivered GEAW forces, combined with short Class III and vertical elastics to control the vertical dimension and obtain clockwise mandibular rotation.

Results: After 22 months, bilateral Class I relationships, positive overjet/normalized overbite, coordinated arches, and improved soft‑tissue profile were achieved without TMJ symptoms.

Conclusion: In growing patients with a mesofacial pattern, controlled posterior extrusion with GEAW can facilitate clockwise mandibular rotation and reduce the clinical appearance of skeletal Class III without surgery

Dao Quang Huy is a dentist based in Vietnam and an independent orthodontic educator specializing in advanced biomechanics in contemporary orthodontics. His clinical and academic expertise focuses on MEAW (Multiloop Edgewise Arch Wire) and GEAW techniques, with a particular emphasis on managing complex malocclusions and enhancing dentofacial esthetics.

He has designed and led intensive orthodontic training programs that equip clinicians with both a robust theoretical foundation and practical skills in these biomechanical systems. Through these programs, Dr. Huy emphasizes individualized treatment planning and precise force control, enabling predictable and esthetically driven treatment outcomes.

In addition to his educational initiatives, Dr. Huy has been invited as a speaker at eight major orthodontic conferences in Vietnam between 2024 and 2026. He has also authored four publications in international orthodontic journals, focusing on treatment strategies that enhance smile esthetics and facial harmony. His work is dedicated to advancing orthodontic practice through biomechanics-based, patient-centered approaches.
