Orthognathic Surgery
What is Orthognathic Surgery or Corrective Jaw Surgery?
Orthognathic Surgery, known as Corrective Jaw Surgery corrects minor and major dental and skeletal abnormalities. Corrective jaw surgery includes the correction of misaligned jaws and teeth, which will improve speaking, chewing, and breathing. The primary goal is to correct your functional problems, but this procedure can also dramatically enhance your appearance.
What Conditions May Require Corrective Jaw Surgery?
Chronic jaw joint or jaw pain and headaches
Open bite (a space between your upper and lower teeth when your mouth is closed)
Birth defects or facial injury
Unable to make lips touch without strain
Difficulty biting and chewing food
Difficulty swallowing
Sleep apnea (unable to breathe properly while sleeping, including snoring)
Facial appearance is unbalanced from the front or side
Chronic dry mouth and mouth breathing
Excessive teeth wear
Protruding jaw (See Figure 1)
Receding chin (See Figure 2)

  Upper jaw is protruding out causing an overbite   The bone in the front  portion of the jaw is sepaarted and the front is repositioned forward.  
What Causes Jaw Misalignment?
Sometimes, the upper and lower jaws grow at different rates. Also, birth defects and injuries can also cause jaw misalignment. Orthodontics can usually correct bite problems when only your teeth are not aligned; however, corrective jaw surgery may be necessary to correct jaw misalignment.
How Do I Know if I Need Corrective Jaw Surgery?
Dr. Karas will work with your Dentist and Orthodontist to determine whether you need corrective jaw surgery. We will determine which procedure will correct your problem. Your treatment will likely include orthodontics before and after corrective jaw surgery, which can take several years to finish. Dr. Karas, along with your Orthodontist and Dentist will determine the course of treatment that best suits your needs.
What is the Treatment Plan for Corrective Jaw Surgery?
Orthodontic Braces:
Prior to surgery, you will need to wear braces that will move your teeth into a new position. Since your bite is being prepared so your teeth fit together after surgery, you may think that your teeth don’t fit together properly and your mouth is getting worse. However, when Dr. Karas repositions your jaw, your teeth should fit well together.
Closer to surgery, we will take additional x-rays and models of your teeth to ensure that your teeth will be properly aligned during surgery.
Corrective Jaw Surgery:
This procedure can be performed under general anesthesia and can take anywhere from one to several hours to finish. Dr. Karas will reposition your jaw to suit your specific needs. Bone may be added, reshaped, or taken away. You also may require screws, surgical plates, rubber bands and wires to secure your jaws in their new locations. Usually, incisions are made inside your mouth to reduce noticeable scarring. Some cases require some small incisions on the outside of the mouth. We will minimize the appearance if these incisions are necessary.
After Surgery:
Dr. Karas will instruct you to modify your diet, which could include liquids and solids, with a schedule for changing over to a normal diet. You should also avoid using tobacco products and engaging in strenuous physical activity.
Pain after your corrective jaw surgery can be easily managed with medication and you will be able to return to school or work between one and three weeks after surgery. Initial healing takes about six weeks; however, total healing of the jaw bears nine to 12 months.
