Underbite - TMJ: Is there surgery that will correct an underbite and TMJ? ...Visitor from CA
To answer your question, I am guessing that your definition of an "underbite" is that your lower
jaw sticks out past your upper jaw. If that is the case, surgery is the best option to reduce the size of your jaw.
The diagnosis is important because if the upper jaw is too small and the lower jaw is normal in
size then the surgery has to be on the upper jaw to make it larger. If the upper jaw is normal and the
lower jaw is too large, then the surgery needs to be on the lower jaw to reduce its size.
The diagnosis is determined by profile photography and cephlometic radiograph.
