Prognathism is a condition in which one jaw (upper or lower) protrudes out further than the other. This condition has been classified as malocclusion and it presents various problems, including the inability to perform ordinary oral functions, worn dentition, and temporomandibular joint (TMJ) disorder. While some mild cases of prognathism can be treated with simple orthodontic treatment, the most effective way to treat this condition is oral surgery. This article talks more about treating prognathism with oral surgery.
Causes of Prognathism
Prognathism is mainly a hereditary condition. Most of the patients are born with a protruding jaw. However, some people develop this problem later in life due to excessive growth hormones in the body. This problem is also suspected to stem from other little-known conditions. The good thing is that prognathism can be treated.
How Oral Surgery Helps to Improve Prognathism
When your jaws are misaligned, you will experience difficulty performing normal oral functions like eating, speaking, and laughing. It can also cause severe pain in your jaw or face as well as relentless headaches. And because your jaws are misaligned, your teeth will make the wrong contact every time you try to bite or chew, resulting in worn-out teeth. Consequently, you will have fragmented or fractured teeth with deep cavities. The protruding jaw will be corrected with oral surgery, allowing you to enjoy a natural occlusion and perform ordinary oral functions comfortably. This surgery can involve aligning the position of your jaw by moving it forward or backward or doing away with the excess jawbone. However, it is important to note that if this functional cross-bite is preserved over time, it can become skeletal, hence the need for early treatment. If you notice this problem in your child, it should be corrected before his or her jawbone is fully grown.
There are two main types of oral surgery used to treat prognathism: bimaxillary surgery and monomaxillar surgery. Bimaxillary surgery becomes necessary when the maxillofacial surgeon needs to intervene surgically on your mandibular and maxillary bones, while monomaxilar surgery is used when the maxillofacial surgeon wants to only act on one of your jaws. In bimaxillary surgery, the maxilla can be moved in three dimensions to make up for its deficiencies and divide it if it shows transversal deficiency.
Then the jaw will be pushed forward or pulled back to align with the maxilla according to the patient’s needs. In both surgeries, a mentoplasty may be necessary to create the desired aesthetic balance. For more information on prognathism, get in touch with Head and Neck today.
