Mandibular Prognathism Treatment: A Solution to Improve Function and Facial Aesthetics

Mandibular prognathism is a facial deformity characterized by a prominent or protruding mandible, which can affect facial aesthetics and masticatory function. Although commonly known as "big jaw," jaw prognathism can vary in severity, and treatment may be necessary to improve facial function and appearance.

What is Mandibular Prognathism?

Mandibular prognathism is a facial condition in which the lower jaw extends forward more than normal, resulting in a "big jaw" appearance. This condition can be inherited or it can develop due to abnormal growth of the jaw.

People with prognathism of the jaw, also called prognata, may experience difficulties chewing and speaking, as well as dental and breathing problems. Therefore, early treatment of mandibular prognathism can prevent long-term complications and improve quality of life.


Causes of Mandibular Prognathism

Jaw prognathism can be caused by a number of factors, including:

  • Genetics: This condition can be inherited from one or both parents, and can manifest from childhood or during adolescence.

  • Abnormal growth of the jaw: In some cases, jaw prognathism can develop due to abnormal growth of the lower jaw.

  • Eating habits: A diet rich in soft foods and inadequate chewing can contribute to the development of mandibular prognathism.

  • Facial trauma: A severe facial injury can cause a jaw deformity, which can be treated by maxillofacial surgery.

Treatments for Mandibular Prognathism

Treatment of jaw prognathism depends on the severity of the condition, the age of the patient, and the underlying cause. The following are the most common treatment options for mandibular prognathism:

  1. Maxillary Orthopedics

In some cases, maxillary orthopedic treatment may be recommended for mandibular prognathism in children and adolescents. This treatment involves the use of orthotics to guide the growth of the jaw and correct its position. Orthotics can also help improve chewing function and facial appearance.

  1. Orthognathic surgery

Maxillofacial surgery is a common treatment option for mandibular prognathism in adults. During surgery, the lower jaw can be cut and repositioned in conjunction with the maxilla to improve its position, relationship, function, and esthetics.
