For competent selection of the most effective method of treatment is required to begin to establish a kind of anomaly, which is observed for a particular child. They are as follows:

  1. Open – when some individual units on the two jaws are not closed completely in the closed state. Often a defect occurs in the front due to prolonged sucking of the thumb or a pacifier, but sometimes on the side. Also contribute to the emergence of such problems may rickets. For correction of this anomaly should remove the original cause, and only then taken for selection of orthodontic appliances. The most commonly used special sling with rubber or traction devices in the form of an expansion plate on springs.
