Description
Ngoc Bich T. Nguyen and Linh Thuy Nguyen describe braces-only treatment of a thirteen-year-old boy with a Class III bite, where the lower jaw sits ahead of the upper. The 2026 case report notes that his upper jaw was also narrow, causing crossbites front and back plus facial asymmetry, and that the family declined jaw surgery. Three-dimensional imaging confirmed a major width mismatch.
Skeletal expansion of the upper jaw widened it by six millimeters. The lower jaw then settled into a better position on its own, and facial balance improved. Standard angle measures showed the jaw relationship nearing normal while height measures stayed stable. Later braces and elastics finished the bite. The authors credit treating the width problem, while warning against generalizing to severe cases.
