Orthognathic surgery is needed when the upper and lower jaw don’t meet correctly because they may be disproportional to each other in size or shape and prevent the teeth from fitting properly. Braces are used to align the teeth, and corrective jaw surgery is used to reposition the misaligned jaws. This not only improves facial appearance, but also ensures that teeth meet correctly and function properly.
People who can benefit from orthognathic surgery include those with an improper bite or whose jaws are positioned incorrectly. Jaw size disproportions arise from the upper and lower jaws growing at different rates, often influenced by genetics. The result can be a host of problems that can affect chewing function, speech, long-term oral health, and appearance. Injury to the jaw or birth defects can also affect jaw alignment. While orthodontics alone can correct many bite problems, the combination of braces and jaw surgery may be required if there is a skeletal discrepancy. Jaw surgery will help correct bite problems that braces alone would not be able to correct.
