Orthognathic Surgery

What is Orthognathic Surgery?

Sometimes the relationship between the upper and lower jaw requires more substantial realignment than can be achieved with orthodontics alone.

Orthognathic surgery can surgically reposition the jaws, realigning them and improving the way they function. It can lengthen or shorten the jaws, move them up or down or in or out. Surgery is used in conjunction with orthodontics, creating a more harmonious relationship and improving overall facial aesthetics.

Often it is necessary to wear braces before orthognathic surgery, and during healing until teeth and jaws are realigned correctly.

Who Can Have Orthognathic Surgery?

Orthognathic surgery is usually performed after jaw growth is complete, around age 14 to16 for females and aged 17 to 21 for males. Our orthodontist Dr Grove can examine your jaw growth to determine the best time for surgery.

What are the Advantages of Having Orthognathic Surgery?

The jaws need to work harmoniously with each other. Orthognathic surgery can improve overall appearance and can correct facial imbalances such as small chins, crossbites, underbites and overbites. It also protects the jaw joints. When the jaws are not in the correct alignment, it can place stress on the jaw joints (temporomandibular joints), causing pain and inflammation. Additionally, when teeth bite together properly, it reduces the risk of excessive wear and tear that could damage teeth. Biting and chewing is easier, aiding digestion and the lips will close comfortably over teeth. Other potential health benefits include improved breathing and improvement in any speech impediments.

What to Expect During Orthognathic Surgery?

Surgery is generally performed under general anaesthesia inside the mouth, so there are no visible scars. If additional bone is needed, it may be taken from elsewhere such as the hip or rib. Once the jaw is moved into the correct position, it is held in place with tiny screws, plates, wires or bands. Healing after surgery can take several weeks, and once initial healing is complete, teeth are realigned with braces. It is a complex process that can take several years to complete fully, but which can provide benefits that last for life.
