Prognathism is an extension or protrusion of the lower jaw.
It occurs when the teeth are not properly aligned due to the shape of the face bones.
The condition affects fewer than 1 per cent of the population.
An extended jaw can be part of a person's normal face shape that is present at birth.
It can also be caused by other conditions, such as Crouzon syndrome, in which there is premature fusion of the fibrous joints (sutures) between certain bones of the skull.
Prognathism may develop over time in children or adults as the result of excess growth in conditions such as gigantism.
