DENTAL APPLIANCES FOR CREATING OPPOSING COUNTER MOMENTS BETWEEN TEETH

Abstract: a dental appliance may include a first plurality of tooth receiving cavities for anterior teeth and a first plurality of attachment receiving cavities shaped to impart a first plurality of forces and a first counter moment to the anterior teeth, the first plurality of forces being to direct at least one tooth in a posterior direction. the dental appliance may include a second plurality of tooth receiving cavities for posterior teeth and a second plurality of attachment receiving cavities to impart a second plurality of forces and a second counter moment the posterior teeth, the second counter moment being in a direction opposing the first counter moment. at least a portion of the second plurality of forces may be configured to oppose the first plurality of forces. the first counter moment and the second counter moment may be configured to be coupled to form a differential moment.
