Orthognathic surgery is performed on the jaws to put them in to the correct position. This will improve a person’s ability to chew and speak. Breathing may become easier for some people. The surgery may also improve facial appearance.
Jaw problems that may be corrected by orthognathic surgery include jaws that are too large, too small, too far forward, too far back, or crooked. There may be a significant gap between the upper and lower front teeth.
The causes can vary. For example, the problem may have a) been present at birth, b) developed as the jaws grew, c)occurred due to trauma or disease.
When a person needs orthoganthic surgery, it is usually performed in conjunction with orthodontic treatment to correct problems with the occlusion, commonly called “bite” (that is, the contact of the teeth between the upper and lower jaws as they meet during chewing or when the jaws are closed).
Dr Poon will discuss your individual needs and whether orthoganthic surgery is required for your presenting situation. If so, she will refer you to the appropriate oral maxillo-facial surgeon to assess your needs.
