This constricted maxillary jaw makes the central teeth protrude. This makes the two front teeth overly prominent. The patient elected to treat this with fixed teeth braces. Thumb sucking past childhood can contribute to this dental arch form.

Treatment of a constricted upper jaw with fixed braces six months post-op. This patient now exhibits a more rounded arch form and a prettier smile. The amount of change in the arch form is limited in an adult – like this case – compared to the amount of change that can occur in a developing adolescent. Photo #2 of 2.
