Orthognathic and corrective jaw surgery

Causes, Procedure of Jaw Surgery


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.


Reasons for Orthognathic and Corrective Jaw Surgery

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.
  • Chronic Jaw, Muscle Pain, and Headache – The misalignment of the teeth alters the way the facial muscles interact. Now and again, the meniscus cartilage which serves as a cushion between the jaws can be painfully damaged.
  • Overbite damages loose Teeth – When uneven pressure is constantly exerted in unintended places or soft tissue, adjacent teeth may turn out to be loose in their sockets which cause pain and reduces proper function.
  • 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.


What does Orthognathic and Corrective Jaw Surgery involve?

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. Your oral and maxillofacial surgeon, your orthodontist and your dentist will work together and consider how the corrective surgery will affect both proper jaw function and the stylish appearance of the entire face.

Orthodontic braces are necessary to align the arches and straighten the teeth before the surgery, and moreover, retainers might be utilised after the surgery. Amid maxillary surgery, the upper jaw is moved and might be secured in position utilising small plates, wires, rubber bands, and screws. Surgery on the mandible is performed using bone grafts to align the lower jaw into the correct position. Orthognathic surgery requires a general anaesthesia and a good deal of aftercare. Pain prescription will be prescribed as necessary, and you’ll be given post treatment advice for your recovery. You may likewise be provided with a modified diet (if required).
