– Difficulty chewing/biting food
– Difficulty with swallowing
– Excessive wear of the teeth
 -Chronic jaw/jaw joint (TMJ) pain & headache
– Open bite
– Unbalanced front/side facial-appearance
– Facial injury
– Birth defects
– Protruding jaw
– Receding chin
– Inability to make lips meet without too much straining
– Sleep apnea (breathing problems while sleeping, includes snoring)
– Chronic mouth-breathing & dry mouth

Who Requires Corrective Jaw Surgery?

Individuals who may benefit from corrective orthognathic (jaw) surgery include those who have an improper bite that results from misaligned jaws and/or teeth. In some cases, the lower & upper jaws might grow at different rates. Certain birth defects or Injuriescan affect the alignment of the jaw. Orthodontics can generally correct bite/”occlusion,” problems when teeth are misaligned, corrective orthognathic surgery might be required to correct jaw misalignment.

Evaluating Whether You Need Corrective Jaw Surgery

Your dentist, orthodontist as well as Oral & Maxillofacial Surgeon work closely  to determine if you are a suitable candidate for orthognathic, surgery. The Oral & Maxillofacial Surgeon determines exactly which surgical procedure is appropriate & the actual surgery will also be performed by him/her.

It is very important for a patient to understand that the treatment can include orthodontics before & after surgery, and might take a number of years to complete. Your Oral & Maxillofacial Surgeon as well as  orthodontist understand that since it is a long-term commitment, they will attempt to realistically estimate the actual time that will be required for your treatment.

This type of corrective jaw surgery might reposition all/part of the lower jaw, upper jaw, & chin. When you are fully-informed about your specific case & treatment options, you & your dental team will then determine the complete course of treatment which suits you best.

Corrective Jaw Surgery – The Procedure

– Before your surgery, the orthodontic braces move your teeth into their new position.

– Since your teeth are now being moved into the position that will fit together post surgery, at first, you may think your bite is actually getting worse instead of better.

– However, when your jaws as repositioned by the Oral & Maxillofacial Surgeon during surgery, your teeth will then fit together properly.

– As the pre-surgical orthodontic treatment reaches completion, additional/ updated records, including the x-rays, pictures & models of your teeth, might be taken to help in guiding your surgery.

– Based on the procedure, corrective surgery might then be performed under general anesthesia in a hospital-setting, an ambulatory surgical-center/in the oral &  maxillofacial surgery office.

– The surgery may take between 1-several hours to complete.

– Your Oral & Maxillofacial Surgeon will ensure that your jawbones are repositioned  in accordance with your individual needs.

– In certain cases, bone might be added/taken away/reshaped.

– Surgical plates/screws/wires & rubber bands might be used to securely hold your jaws in the new positions.

– Generally, incisions are made inside the mouth- this is done to reduce visible scars; however, in some cases, small incisions may be required outside the mouth. In the cases where this is necessary, great care is taken to visibly minimize their appearance.

– After surgery, the surgeon will then provide instructions for a modified-diet. This might include solids & liquids. You will also be given a schedule to transition to a normal diet. You might also be asked to avoid using tobacco products & avoid any strenuous physical activity.

– The pain that follows corrective jaw surgery can be easily controlled with prescribed medication.

– Generally, patients are able to return to work/school within 1-3 weeks post surgery, based on how they are feeling.

– The initial healing phase is around 6  weeks,  but complete jaw healing takes between 9-12 months.
