What Is Double Jaw Surgery (Bimaxillary Osteotomy) ?

Double jaw surgery is a surgical operation performed on your jaws to reduce the size of your upper teeth. This type of surgery is used to treat dental problems such as: TMJ disorder, mandibular agenesis, maxilla malformation, cleft lip or palate. There are two types of double jaw surgeries: Bimaxillary osteotomy and Mandibular osteotomies.

How Does Double Jaw Surgery Work?

The surgeon makes a cut in your lower jaw bone, usually at the level of the angle between your upper and lower jaws. A metal plate called a “scissor” is then inserted into this area. The scissor creates a groove which allows food to pass through it. The surgeon uses the groove to pull out some of your upper teeth while leaving others behind. The remaining teeth are either replaced with larger ones or removed completely.

Is Double Jaw Surgery Dangerous?

No, double jaw surgery is not dangerous. However, there have been cases where the surgeon made mistakes during the operation. These errors could lead to infection or even death if they were not corrected immediately. If complications occur, these may include bleeding from the incision site and infections in both jaws.

What Is Double Jaw Surgery Success Rate?

The success rate of double jaw surgery is high. The most common type of double jaw surgery patients are people who suffer from mandibular agenesis. Most people who undergo the procedure have difficulty chewing and swallowing food properly. These problems are eliminated after the operation as teeth can grind food easily and improve chewing capacity. In some cases, double jaw surgery can even help people chew better.

How to Prepare for Double Jaw Surgery?

There are several things you should do before undergoing the double jaw surgery procedure. First, your dentist should give you a thorough examination. This will help determine whether you need the procedure or not. Ask your dentist about any risks and how long the operation takes. You can also talk to a surgeon who has experience in performing double jaw surgeries. Make sure they answer all your questions before making a decision.

You should also make sure that you are in good health before undergoing the procedure. Your blood should be free of any diseases and you should not suffer from heart disease or have any other health problems. Double jaw surgery is also not suitable for people who smoke.

If you are over 40 and have been a smoker for most of your life, it is best to stop smoking at least six months before the operation.
