Jaw Shape

Long Jaw Skeletal

Patients with long lower jaws often have short upper jaws as well. This gives rise to a crescent-moon side view of the face/ concave face. We call this a Class III jaw. Oftentimes, patient’s teeth are in a reverse bite/ an underbite.

Treatment depends on the severity of the jaw discrepancy. It is possible to camouflage or disguise mild to moderate Class III jaw profiles with braces or Invisalign. Moderate to severe cases may need  long jaw surgery to correct this problem.

In young children, it is possible to intercept and correct a short upper jaw with growth modification.
