Understanding Orthognathic Surgery

A jaw that’s too small, too large, or crooked can cause problems with chewing, speaking, breathing, and even sleeping. The shape of your jaws also affects the way your face looks. Orthognathic surgery is treatment that reshapes the jaws to improve their form and function.

How Orthognathic Surgery Can Help

Some people are born with poorly aligned jaws. Others develop problems as the bones grow or as a result of an injury. Orthognathic surgery realigns facial bones, making jaws work together better. Surgery is only one part of the treatment process. In most cases, treatment to move and straighten the teeth (orthodontics) is needed before and after surgery. This combination of treatments can relieve problems caused by teeth and jaws that are out of alignment.

Your Treatment Plan

Orthognathic surgery and related treatments can take time, often over a year. Starting treatment and not completing it could leave you with more problems than you have now. So you need to commit to the process before treatment begins. Your plan will likely include a time frame for each stage of treatment. Typical stages and time frames are shown here:
