Jaw surgery, or orthognathic surgery, is a corrective surgical procedure to realign or reshape the jawbones. It addresses functional issues, such as difficulty chewing, speaking, and breathing, as well as aesthetic concerns by improving facial symmetry and jaw alignment. This surgery can correct overbites, underbites, crossbites, and open bites, often enhancing both facial appearance and oral health. Typically performed by an oral and maxillofacial surgeon, jaw surgery may involve repositioning the upper or lower jaw, or both, and is commonly used alongside orthodontic treatments for optimal results.
