Abstract

A dental appliance, a system and a method for treating malocclusions are provided wherein a need for patient cooperation to treat the malocclusion may be reduced. The dental appliance may cause teeth of the user to move into a corrected position. As a result, the patient may not be required to perform an amount of exercise, or like co-operational action, normally required by the patient to correct the malocclusion. In another embodiment, the method of exercise or cooperation performed may reduce an amount of time the dental appliance is worn in the mouth on a daily basis.
