Orthognathic means "straight jaws", and orthognathic surgery corrects these jaw and facial deformities, usually in conjunction with an orthodontist, so that after the jaws are corrected, the teeth will come together properly.
Sometimes, braces alone can correct a problem with the bite, but when it is severe, usually orthognathic surgery is required. Abnormal jaw and facial development can be genetic or acquired due to disease or injury. When the jaws are not properly developed or proportioned, problems such as difficulty chewing, jaw and facial pain, speech abnormalities and dental problems can result. Using sophisticated surgical techniques, the facial bones can be repositioned in order to restore proper function and facial appearance.
In the past, thin wires were used to support the bones in the new positions, but because this was not stable, the patient also had to endure periods of 6 to 12 weeks of "intermaxillary fixation," or having their teeth and jaws wired together. Not only was this uncomfortable, but oral hygiene was difficult and post-operative weight loss was a problem.
Today, miniature titanium plates and screws are used to fixate the facial bones in their new relationship. This is much more comfortable for the patient, but it is also more stable and predictable.
This, in combination with new instruments and anesthetic techniques, has allowed orthognathic surgery to be safer and more effective, and is much easier for the patient to undergo.
New advances in orthodontics have also allowed the total treatment times to be shortened.
