Using orthognathic surgery, a maxillofacial surgeon can reestablish face balance by working on the bones that support the teeth. This type of surgery is recommended when you have obstruction problems caused by a disharmony between the upper and lower jaws that cannot be treated by braces. A bad alignment of the jaws can lead to eating and breathing problems and be harmful to the wellbeing of the patient. An orthognathic surgery can also be suggested to fight sleep apnea problems. A well-established treatment plan will carefully be laid out by a competent medical team that will answer all of your questions.
