Common Orthognathic Surgery for Correcting an Underbite

Lower jaw surgery: The bilateral sagittal split osteotomy (BSSO) is an operation which is typically used to correct an issue with the lower jawbone. The surgery involves separating the rear part of the jawbone from the front part and then modifying the jawbone to reposition the part of the jaw that carries the teeth further back. 

BSSO is a relatively common procedure, and can be beneficial to those who suffer from a protruding lower jaw which results in an underbite, causing difficulty in eating and speaking.

While this surgery is often used to correct an underbite, and in many cases it can help improve the overall facial structure by providing a more balanced and aesthetically pleasing facial appearance.

In order to ensure the best possible results, patients should consult with their doctor and discuss the risks and benefits of undergoing orthognathic jaw surgery. It is also important to consider the long-term effects of the surgery, as the jaw may need to be adjusted over time.

Mid face surgery : Le Fort Osteotomies

Midface comprises the upper jaw and the nose. Patients with underbite often presents with a deficient upper jaw in combination with a protruding lower jaw. Reposition of the upper jaw is commonly done by cutting the upper jaw at different levels called Le Fort I, II, and III. Le Fort I involves the tooth bearing part of the jaw while Le Fort II extends to a higher level that includes the nose. The Le Fort III Osteotomy is an advanced surgical procedure that involves the reshaping and repositioning of the entire mid face, including the cheek bones. 

Depending on the level at which the mid face is deficient, the surgeon will choose the appropriate Le Fort level to achieve a harmonious and proportionate facial dimension.
