Jaw (Orthognathic) Surgery

Orthognathic surgery repositions the upper and/or lower jaws to correct functional skeleto-facial malrelationships. Examples of functional skeleto-facial malrelationships include:

  1. Mandibular Prognathism: Lower jaw is too long and too far forward. Chin appears too large.
  2. Mandibular Retrognathism: Lower jaw is too short and retruded. Chin appears too small.
  3. Maxillary Open Bite: A vertical gap or opening between upper and lower front teeth when back teeth are closed.
  4. Maxillary (vertical) Excess: Upper jaw is too long creating the appearance of a long and narrow face. Often, too much gum shows when smiling. At rest, lips are often parted. Conscious muscle posturing is required to maintain lip closure. Mouth breathing is common and causes excessive drying of gum tissues creating chronic gingival inflammation.
  5. Maxillary (vertical) Deficiency: Upper jaw is too short making face appear too round and “squatty.” Often shows little or no upper teeth when smiling.
  6. Maxillary (transverse) Deficiency: Upper jaw is too narrow resulting in a dental crossbite, i.e. upper posterior teeth are positioned inside lower posterior teeth.
  7. Maxillary or Mandibular Asymmetry: Upper or lower jaw midline is skewed to left or right.
