Angle Class III malocclusion is a type of dental and facial irregularity in which the lower jaw protrudes outwards in relation to the upper jaw. This can cause the upper jaw to appear recessed and can also lead to problems with the bite and the overall appearance of the face.

It is named after Edward Angle, who is considered the father of modern orthodontics and classified malocclusion in three classes. Angle Class III malocclusion is the less common compared to Angle Class I and II, and it is characterized by an underdevelopment of the upper jaw, a overdevelopment of the lower jaw, or a combination of both. It can also be caused by a combination of genetic and environmental factors, such as thumb-sucking or mouth-breathing. It’s usually treated with a combination of orthodontic treatment and jaw surgery.

Treatment for Angle Class III malocclusion usually involves a combination of orthodontic treatment and jaw surgery. The specific treatment plan will depend on the individual case and the severity of the malocclusion.

Orthodontic Treatment:

• Braces: Traditional metal braces can be used to correct the position of the teeth, which can improve the bite and the overall appearance of the face.
• Clear aligners: Clear aligners, such as Invisalign, can also be used to correct the position of the teeth, but they are virtually invisible and can be removed for eating and brushing.
• Headgear: A device worn on the head that attaches to the braces, it is used to pull the upper jaw forward and correct the overbite.

Jaw Surgery:

• In some cases, orthodontic treatment alone may not be enough to correct the jaw position, and jaw surgery may be necessary. The most common type of jaw surgery for Angle Class III malocclusion is called maxillomandibular advancement (MMA), which involves moving the upper jaw forward and the lower jaw backward to correct the overbite.
• Another jaw surgery option is a bimaxillary surgery, where both the upper and lower jaw are moved to correct the malocclusion.

It’s important to note that the treatment options and timing may vary depending on the severity of the malocclusion and the patient’s age, as well as the patient’s preferences and goals. A comprehensive evaluation by an orthodontist is necessary to develop a personalized treatment plan.
