What
is surgical orthodontics?
Just as orthodontics repositions teeth, surgical orthodontics (also
known as orthognathic surgery) corrects jaw irregularities to improve the
patients ability to chew, speak, and breathe and for improved facial appearances.
In other words, surgical orthodontics straightens your jaw. Moving the jaws
also moves the teeth, so braces are always performed in conjunction with
jaw correction. This helps make sure teeth are in their proper positions
after surgery.
Who needs surgical orthodontics?
Your orthodontist will consider surgical orthodontic treatment
for non-growing adult patients with improper bites and those with facial
esthetic 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.
How does it work?
During your orthodontic treatment, which usually lasts 6-18 months,
you wear braces and will visit your orthodontist 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),
your orthodontist "fine-tunes" your bite. In most cases, braces
are removed within 6 to 12 months following surgery. After your braces are
removed, you will wear a retainer to maintain your beautiful new smile.
