Where Does Prognathism Occur?

Prognathism happens when your lower jaw, upper jaw, or both halves of your jaw protrude beyond the normal range. It can be caused by a genetic or inherited condition or an underlying medical condition. It can also develop for unknown reasons.

Where is the prognathism located?

Prognathism is a positional relationship of the mandible or maxilla to the skeletal base where either of the jaws protrudes beyond a predetermined imaginary line in the coronal plane of the skull.

How do you know if you have prognathism?

Symptoms of Prognathism
  • Protrusion of either the upper or lower jaw (or both)
  • An underbite or an overbite (depending on the type of prognathism)
  • Difficulty talking.
  • Difficulty eating and chewing.
  • Breathing complications.
