Dentoalveolar open bite can be caused by genetics, dysfunctional swallowing, speech disorders, oral habits or mouth breathing due to enlarged lymphatic tissues or allergies. The positioning of the tongue during swallowing and speech and when at rest plays a major role in the development of open bite, aside from any genetic predispositions. Kasparaviciene et al. found that 71.4% of the children included in their study presented with one or more attributes of malocclusion and 16.9% displayed oral habits. They found that digit suckers have a higher incidence of anterior open bite and posterior reverse articulation. The infantile swallow pattern demonstrated a strong association with anterior open bite.
