Mandibular deviation

mandibular deviation

As the name implies, mandibular deviation is a skeletal malformation in which the mandible is deviated to one side. Midline discrepancy can be clearly seen in this anomaly. Mandibular deviation can be congenital or acquired. In the acquired type, the jaw usually deviates to one side as a result of inappropriate fracture and fusion in childhood.

Weakness of one side of the face is another cause of mandibular deviation, where the jaw tilts to one side. mandibular deviation also occurs due to dental interference in the maxilla and mandible as well as untreated posterior cross bite. In some patients, TMJ enlarges in one side due to an unknown reason, resulting in jaw deviation or so-called hemimandibular hypertrophy.

Mandibular deviation treatment

If diagnosed at an early age, jaw deviation can be treated through orthodontics alone. However, orthodontic surgery may be required if treatment is performed at an older age, especially after puberty.

Treatment methods in childhood include the use of a hybrid functional appliance, posterior cross bite correction or early dental contact correction. If jaw deviation is due to hemimandibular hypertrophy, no treatment is performed and the TMJ is allowed to be grown until the growth ends, and then orthodontic surgery will be performed.

The following images show a patient with jaw deviation caused by maxillary and mandibular dental interferences.

The patient referred at the age of 12 and surgical treatment was recommended due to an obvious jaw deviation. But only orthodontic treatment was performed because of disagreement of the patient with surgical intervention. The following images show the patient after orthodontic treatment. The following images show a patient with jaw deviation caused by maxillary and mandibular dental interferences.
