Types of Jaw Surgery
There are several different types of jaw surgery available depending on exactly what condition you are experiencing. Some of these include mandibular osteotomy, maxillary osteotomy and genioplasty.
Mandibular osteotomy is used when patients have a receded lower jaw that causes an overbite. To perform this procedure, our oral & maxillofacial surgeon incises the left and right sides of the lower gums, just behind the molars. A cut is made into the bone so that the joint can be relocated to a proper position. The jaw is then held in its new position with plates and screws.
Maxillary osteotomy is used for a similar condition, a receded upper jaw. This leads to an underbite, crossbite, and open bite. Our oral & maxillofacial surgeon incises the upper gums to reshape the jaw and relocate it into the proper spot. Your teeth will be held to your jaw with a plastic wafer. The jaw is then held in its new place with metal plates and titanium screws, like with mandibular osteotomy. We also perform bimaxillary osteotomies, which are used when you need this procedure on both your upper and your lower jaw.
Genioplasty is performed for a receding chin. The procedure is also often performed at the same time as a mandibular osteotomy since the conditions are often related. Our oral & maxillofacial surgeon incises the lower gum and lip in the front. The chin bone is then cut and moved into the correct spot. We hold it in its place using the same plates and screws that we use for the other surgeries.
Surgical preparation will look different for each individual patient. In some cases, our oral & maxillofacial surgeon may require you to wear braces, retainers, mouthguards, and other pieces of dental equipment in the time leading up to surgery.
