How you prepare

In most cases, an orthodontist places braces on your teeth before surgery. Braces are usually on for 12 to18 months before surgery to level and align your teeth in preparation for surgery.

Your orthodontist and oral and maxillofacial surgeon work together to develop your treatment plan. X-rays, pictures and models of your teeth are part of the planning for your jaw surgery. Occasionally, the difference in the way teeth fit together will require either reshaping of the teeth, covering the teeth with crowns or both to complete correction.

Three-dimensional CT scanning, computer-guided treatment planning and temporary orthodontic anchoring devices may be used to help in the movement of teeth and decrease your time in braces. Sometimes these efforts completely eliminate the need for jaw surgery.

Sometimes virtual surgical planning (VSP) will be used to guide your surgeon to fit and correct the jaw segment position during the procedure for the most optimal result.
