Orthognathic surgery involves correcting issues that have to do with the jaw. It is often done to fix alignment problems where the upper and lower jaw are not perfectly lined up. Such problems can often cause difficulties among patients when speaking or eating, thus necessitating a surgical solution.
The problems that this method is meant to resolve can be caused by a number of issues, including birth defects, development flaws, accidents, and illnesses. Regardless of the cause, it’s worth noting that orthognathic surgery is not done in a single session. It can take upwards of several years to fully fix the jaw problem, depending on the severity of the issue.
