Lowell K. Anderson, D.M.D.  Oral and Maxillofacial Surgeon 

Your orthognathic team repositions your teeth and reshapes your jaws during the orthognathic surgery process. Your orthodontist, a dentist who specializes in the straightening of teeth, uses braces to move your teeth into correct position for the bite you'll have after orthognathic surgery. Your surgeon, specially trained in this type of corrective jaw surgery, reshapes your jaws and possibly other facial bones during surgery to form a better bite and a more pleasing appearance.
 

An "open bite" exists if thereis space between the upper and lower teeth when the mouth is closed.	Candidates for orthognathic surgery can suffer from "retrognathia" or a receding lower jaw, often called a weak chin.	A prognathic jaw occurs when the lower jaw is overdeveloped and protrudes out beyond the upper jaw.
