If bone structure is too far away from each other, there are limitations to adult and sometimes child orthodontics. Trying to correct bone structure problems with orthodontics alone can worsen the outcome. For those cases, jaw surgery along with braces will give the best outcome. In addition, some jaw problems cause sleep apnea, which can be helped and/or cured with jaw surgery if identified with a sleep study.
All other means of treatment should be eliminated prior to considering jaw surgery. The patient must know all the alternatives and possible complications associated with surgery. The orthodontist must work in conjunction with a surgeon to get the best outcome. Not all orthodontist or surgeons are trained and/or qualified to do jaw surgery. Therefore, it is essential that you ask your orthodontist how many jaw surgery cases they have done and if they are a Board Certified in Orthodontist.
