Abstract:
Objective To investigate the the treatment of class Ⅲ malocclusion by orthognathic surgery combined with postoperative orthodontics.Methods Nine patients with skeletal class Ⅲ malocclusion were treated by surgery-first approach without pre-surgical orthodontic from January 2012 to August 2014.The studied sample consisted of 7 women and 2 men (aged 15-28 years old, mean age 19.7 years), who had obvious mandibular protrusion.2 to 3 days after surgery, intermaxillary traction was used to made the maxilla and mandible together by board;we replaced a rubber band every 2 to 3 days and lasted for four weeks.We would dismantle board and performed conventional orthodontic treatment after patient's facial swelling subsided, and the positional relationship between the jaw stabilized.Results The face type of 9 patients were greatly improved after orthodontic treatment for 6.5 to 19.5 months.Patients and their family members felt satisfied, and their occlusal function returned to normal.At 3 to 32 months follow-up, the postoperative appearance and occlusion were becoming good without obvious signs of recurrence.Conclusions The surgery-first approach is an effective method to treat skeletal class Ⅲ malocclusion.
