Orthognathic surgery refers to the surgical correction needed to fix substantial abnormalities of the maxilla (upper jaw), the mandible (lower jaw), or both. The abnormality may be a birth defect, a growth defect, or the result of traumatic injuries to the jaw area.
Orthognathic surgery is generally performed by an Oral and Maxillofacial Surgeon to correct malocclusion (bad bite) in cases where routine orthodontic treatment has not or will not be effective. Orthognathic surgeries include the reconstruction of the mandible or maxilla, mandibular ramus, maxilla osteotomy, and mandibular osteotomy.
Reasons for Orthognathic Surgery
The malocclusion of the teeth can create greatly destructive forces among the five powerful muscles that control the closing and opening of the jaw. These muscles generate a tremendous force when clenching, grinding or chewing. Misalignment can seriously damage the function and aesthetic appearance of the teeth in many ways if left untreated, such as:
- Tooth Wear – In the case of an overbite, the pressure and wear on the teeth is not spread evenly. This can also lead to TMJ, migraine headaches, and tooth loss.
- Chronic Jaw, Muscle Pain & Headache – The misalignment of the teeth alters the way the facial muscles interact. In some cases, the meniscus cartilage which acts as a buffer between the jawbones can be painfully damaged.
- Loose Teeth – When uneven pressure is continually exerted in unintended places or soft tissue is damaged by an overbite, adjacent teeth may become loose in their sockets which causes pain and reduces proper function.
- Tooth Sensitivity – As teeth become damaged by constant use, the enamel becomes thinner and the nerves are less protected. This lack of protection can lead to sharp pains when hot or cold foods are eaten.
- Difficulty Swallowing, Chewing, or Biting Food – Each can be associated with muscle pain and/or poor alignment of the upper and lower jaws.
Before any treatment begins, a consultation will be held to perform a complete examination with x-rays. During the pre-treatment consultation process, feel free to ask Dr. Chawla any questions that you have regarding your treatment.
