Thanks for the question. As an oral & maxillofacial surgeon, jaw surgery is a very technical dental procedure that is under our dental specialty. Each successful case requires close teamwork and communication between an oral surgeon and orthodontist.

Your oral surgeon will first determine what type of corrective jaw surgical procedure is appropriate in your case. He/she is also the one carrying out the procedure.

I normally do a joint consultation with an orthodontist at our group practice for my patients so that they are clear of the entire process – orthodontics and surgery. During the consultation, a CT-scan and radiographs will be taken so that your dental condition can be correctly diagnosed.

The surgery portion is performed after the pre-surgical orthodontic phase is completed, when your teeth are in the correct surgical alignment.

Here are some common types of jaw surgery:

  • To correct an open bite: some of the bone in the upper jaw is removed and the upper jaw is secured in its new position
  • To correct a protruding lower jaw (underbite): bone in the back portion of the jaw is separated from the front and surgically modified so that the lower jaw can be moved back into proper alignment
  • To correct a receding lower jaw: the bone in the lower portion of the jaw is separated and modified so that a portion of the chin can be repositioned forward

When the jaw is aligned, the new alignment will be held together with screws and plates underneath your gums. These screws and plates are osseointegrated and fully compatible with your body, hence there is no need to take them out.

The surgery is mostly done from the inside of your mouth so that there are no scars on your face, chin, jaw and around the mouth. In some cases, a small cut may be made on the jaw, but it will eventually go away after a few weeks.

You will be under general anesthesia during the surgery so that you are completely unconscious.

How can I reduce the protrusion of my upper lip?

In order to decide which method would most effective, we would need to assess and treat the cause of the protrusion. If it is due to protruding upper teeth which are flaring out and causing the lip to come forward, braces or Invisalign treatment would be ideal to reduce the protrusion. There may be a possibility that extractions of some teeth may be required to provide some space for the upper front teeth to move back into. Sometimes, it may be due to the imbalance of the upper and lower jaws.

Can Invisalign or braces help to fix a slanted jaw without the need for jaw surgery?

It is great that you are thinking about correcting your bite. With skeletal issues such as a slanted jaw, surgery is indeed required in order to achieve a good stable bite. However depending on the degree of skeletal discrepancy (slanted jaw) braces / invisalign are still options for you to consider in order to straighten out your teeth and give you a good smile. Straight and aligned teeth can be achieved but there are limitations so it depends on what your ideal smile is! My suggestion would be to consider all your options and if needed seek a second opinion.
