Open bite malocclusion

Open bite malocclusion is a type of dental malocclusion where there is a vertical gap or space between the upper and lower front teeth when the back teeth are closed together. This condition can be classified into two types: anterior open bite and posterior open bite.

Etiology

The etiology of open bite malocclusion is multifactorial and can be attributed to both genetic and environmental factors. Genetic factors include skeletal growth patterns and dental development, while environmental factors include habits such as thumb sucking, tongue thrusting, and prolonged use of pacifiers or bottle feeding.

Diagnosis

Diagnosis of open bite malocclusion is typically made through a comprehensive dental examination, which may include dental radiographs and study models of the teeth. The dentist or orthodontist will evaluate the patient's bite and look for signs of open bite malocclusion, such as a gap between the upper and lower front teeth when the back teeth are closed together.

Treatment

Treatment for open bite malocclusion depends on the severity of the condition and the age of the patient. In children, treatment may involve behavior modification to eliminate harmful oral habits, or the use of orthodontic appliances such as a crib appliance or high pull headgear. In adults, treatment may involve orthodontic treatment with braces or Invisalign, or in severe cases, orthognathic surgery may be recommended.

Prognosis

The prognosis for open bite malocclusion varies depending on the severity of the condition and the treatment provided. With early intervention and appropriate treatment, many cases of open bite malocclusion can be successfully corrected.
