Factors that may increase the risk of problems include:
Talk to your doctor about these risks before the procedure.
The change in your jaw will require a change in the position of your teeth. To prepare your teeth for the surgery, you may have several months of dental care. Your dentist may use braces or similar tools to help shift your teeth into the correct position.
Closer to your surgery, you may have x-ray and models of your teeth done. This will help guide surgical work.
Talk to your doctor if you take any medications, herbs, or supplements. You may be asked to stop taking some medications up to 1 week before the procedure.
You may be asked to not eat or drink anything starting the night before your surgery.
General anesthesia will be used. It will block pain and keep you asleep through the surgery.
The exact procedure will depend on your specific needs. Most incisions will be made inside the mouth. Some incisions may need to be made outside of the mouth.
The specific work done on the bones will depend on your needs. Some steps may include:
The bones will be adjusted until the upper and lower teeth are lined up.
The incisions may be closed with stitches or a special liquid that acts like glue. Gauze may be placed over the surgical wounds. The gauze will stay in place for a few hours after surgery. Rubber bands may also be used with a dental appliance. They will help keep your jaw in alignment until your jaw heals.
After the operation, you will be taken to the recovery room for observation. The gauze may be removed when you wake up.
Ice may be placed around your jaw to decrease swelling.
The length of surgery will depend on the changes made to your jaw. It may be 2-4 hours.
Anesthesia prevents pain during surgery. As you recover, you may have some pain. Your doctor will give you medication to manage any pain.
You may need to stay in the hospital for 2-5 days. If you have any problems, you may need to stay longer.
You will be asked to start with a modified diet. Depending on the details of your surgery, your doctor may recommend just liquids at first or soft solids. You will be given a schedule to work back toward your normal diet.
You will be able to notice cosmetic change right away. Your jaw will need to heal before you can do normal movements. As a result, it may take some time to feel the improvements in bite or jaw movement.
Certain activities will need to be avoided until the jaw is healed. You will be instructed on how to care for the incision site to prevent infection. Dietary changes may be need to be maintained at home until the doctor says it is okay to return to a normal diet. A dietitian will help with meal planning.
Contact your doctor if your recovery is not progressing as expected or you develop complications, such as:
