Prognathia

Prognathia is a medical condition characterized by the protrusion of one or both jaws, particularly in relation to the craniofacial structure. This condition can be classified into two main types: Mandibular prognathism (lower jaw protrusion) and Maxillary prognathism (upper jaw protrusion). Prognathia can be a genetic trait, or it can be acquired due to certain medical conditions or trauma.

Types of Prognathia

Mandibular Prognathism

Mandibular prognathism, also known as prognathism of the mandible, is a condition where the lower jaw protrudes beyond the upper jaw. This can lead to a condition known as Malocclusion, where the upper and lower teeth do not align properly.

Maxillary Prognathism

Maxillary prognathism, also known as prognathism of the maxilla, is a condition where the upper jaw protrudes beyond the lower jaw. This can also lead to malocclusion, and may require surgical intervention for correction.

Causes

Prognathia can be caused by a variety of factors, including genetic traits, certain medical conditions such as Acromegaly, and trauma to the jaw. It can also be a characteristic feature of certain syndromes, such as Crouzon syndrome and Basal cell nevus syndrome.

Treatment

Treatment for prognathia often involves a combination of orthodontics and orthognathic surgery. The specific treatment plan will depend on the severity of the condition, the age of the patient, and the patient's overall health.
