Upper Jaw Protrusion


An overgrowth of the upper jaw results in a protruding or excessively long upper jaw (maxilla). In such cases, there is an inability to close the mouth normally. It also leads to a “gummy” smile where too much of the gums is seen while smiling. This can be treated with a cosmetic jaw surgery procedure called Anterior Maxillary Osteotomy. The upper jaw is shortened, reshaped and realigned to be more proportionate.

Orthognathic Surgery Before After Picture

The shape of the nose is influenced by the shape of the upper jaw. Sometimes, the sharpness of the nose is not obvious because the upper jaw is too big and protruding. Occasionally, correcting the shape, size and position of the upper jaw also results in giving the nose a sharp pristine look. More severe variations in the shape of the nose can be corrected along with jaw correction in the same surgical procedure.

This cosmetic jaw correction surgery greatly improves function and enhances cosmetic appearance of the face. Since this procedure is done completely inside the mouth, there are no scars. Commonly, this is done in conjunction with orthodontic treatment, which straightens the teeth. This results in a facial profile that is pleasing or in fact even more beautiful to look at.

Upper Jaw Protrusion

Upper jaw protrusion, also known as maxillary prognathism, is a condition where the upper jawbone (maxilla) grows excessively or is positioned too far forward. This can lead to several cosmetic and functional issues, including:

  • Facial asymmetry
  • Overbite
  • Breathing difficulties
  • Excessive gum exposure when smiling
  • Difficulty in closing the mouth
  • Speech problems


There are two primary treatment options for upper jaw protrusion: orthodontics and surgery.


Orthodontic treatment can correct mild to moderate cases of upper jaw protrusion. This usually involves wearing braces or other dental appliances to gradually shift the upper jawbone into a more appropriate position. Orthodontic treatment can also align the teeth and improve the bite.


Surgery is the preferred treatment option for severe cases of upper jaw protrusion. The two main types of surgery for upper jaw protrusion are:

  1. Le Fort Maxillary Osteotomy: This procedure involves cutting and repositioning the entire upper jawbone. It’s typically used for patients with severe prognathism or those who haven’t responded to orthodontic treatment.
  2. Anterior Maxillary Osteotomy: This procedure involves cutting and repositioning the front portion of the upper jawbone. It’s typically used for patients with mild to moderate prognathism.

Both Le Fort maxillary osteotomy and anterior maxillary osteotomy are major surgical procedures that require a skilled oral and maxillofacial surgeon. Post-surgery, patients can expect some pain and swelling. They’ll also need to follow a soft diet for several weeks and may need to wear a splint or mouthguard to protect the healing bone.

Other Treatment Options

In some cases, other treatment options may be considered for upper jaw protrusion. These include:

  • Genioplasty: This procedure involves moving the chin forward to balance out the protrusion of the upper jaw.
  • Bone Grafting: This procedure is used to add bone to the deficient areas of the jawbone.
  • Fillers: Fillers can be used to temporarily improve the appearance of the upper jaw.
Choosing the Right Treatment

The best treatment for upper jaw protrusion will depend on the severity of the condition and the individual patient’s goals. It’s important to consult with an experienced oral and maxillofacial surgeon to discuss the risks and benefits of each treatment option.
