Orthognathic and Corrective Jaw Surgery refers to the surgical correction expected to settle substantial abnormalities of the maxilla (upper jaw), the mandible (lower jaw), or both. The abnormality might be a birth defect, a growth defect, or the aftereffect of traumatic injuries to the jaw area.
Orthognathic and corrective jaw surgery is performed by our Oral and Maxillofacial Surgeon Sydney, Dr Ryan Wilgus to correct malocclusion (bad bite) in cases where routine orthodontic treatment has not or won’t be effective. Orthognathic surgeries incorporate the reconstruction of the mandible or maxilla, mandibular ramus, maxilla osteotomy, and mandibular osteotomy.
There are several classifications of malocclusion (the improper meeting up of teeth) which may require orthognathic surgery:
- Class I Occlusion –This malocclusion implies that the lower anterior incisors rest directly behind the upper anterior incisors when the patient bites down. This is regarded as less destructive than Class II and Class III malocclusions.
- Class II Malocclusion – This is identified when the lower anterior incisors lie significantly behind the upper anterior incisors amid the biting process; now and again hitting the soft tissue behind the upper incisors. This is usually referred to as an overbite and can bring about discomfort, bone damage, excessive wear of the front teeth, and tooth loss.
- Class III Malocclusion – This is usually known as an underbite and happens when the lower anterior incisors and lower jaw are positioned past the upper teeth, making the lower jaw significantly more prominent than the upper jaw.

The malocclusion of the teeth can create significantly damaging forces among the five-strong muscles that regulate the closing and opening of the jawbone. These muscles create a tremendous force when clenching, grinding or chewing. Misalignment can genuinely damage the function and tasteful appearance of the teeth from multiple points of view if left untreated, for example:
- Tooth Wear – In the case of an overbite, the pressure and wear on the teeth is not spread equally. This can likewise lead to TMJ, migraine headaches, and tooth loss.

- Tooth Sensitivity – As teeth end up noticeably damaged by constant utilise, the enamel winds up plainly more slender and the nerves are less protected. This lack of insurance 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 additionally poor alignment of the upper and lower jaws.

At the point when the dentist recognises a patient as a candidate for orthognathic surgery, a complete photographic analysis is at first undertaken. This incorporates panore x-rays, cephalometric x-rays, models, impressions, and radiographs.

Orthodontic braces are necessary to align the arches and straighten the teeth before the surgery, and moreover, retainers might be utilised after the surgery.
