Orthognathic Surgery

Corrective jaw surgery (orthognathic surgery) treats and corrects abnormalities of the facial bones, specifically the jaws and teeth. Often, these abnormalities cause difficulty associated with chewing, talking, sleeping, and other routine activities that most people take for granted. Orthognathic surgery corrects these problems and, in conjunction with orthodontic treatment, will improve the overall appearance of the facial profile.

Dr. Yi will consider surgical orthodontic treatment for non-growing adult patients with improper bites and those with facial aesthetic concerns. Jaw growth is usually completed by age 16 for girls and 18 for boys. All growth must be completed before jaw surgery can be performed. However the pre-surgical tooth movements can begin one to two years prior to these ages.

During your orthodontic treatment, which usually lasts 6-18 months, you wear braces and will visit Dr. Yi for scheduled adjustments to your braces. As your teeth move with the braces, you may think that your bite is getting worse rather than better. However, when your jaws are placed into proper alignment during orthognathic surgery, the teeth will then fit into their proper positions.

Surgery is performed in the hospital with an oral surgeon, and can take several hours, depending on the amount and type of surgery needed. In lower jaw surgery, the jawbone behind the teeth is separated and the tooth-bearing portion is moved forward or backward, as needed. In upper jaw surgery, the jaw can be repositioned forward or backward, or the jaw can be raised or lowered. Certain movements may require the jaws to be separated, with bone added/removed to achieve the proper alignment and stability. Other facial bones that contribute to alignment may also be repositioned or augmented.

When you have completed surgery, you should be able to return to school or work within two weeks. After the necessary healing time (about 4-8 weeks), Dr. Yi “fine-tunes” your bite. In most cases, braces are removed within 6-12 months following surgery. After your braces are removed, you will wear a retainer to maintain your beautiful new smile.
