Abstract: An orthodontic appliance for positioning one or more anterior teeth in a jaw of a patient comprising a clear labial component which extends over the labial surfaces of the patient's teeth and which has an anterior portion and a pair of posterior portions on opposite sides of the dental arch. The anterior and posterior portions of the labial component are in direct contact with the exterior surfaces of the teeth so that no other components of the appliance are located between the anterior and posterior portions of the labial component and those exterior surfaces of the teeth. A lingual component is located within the patient's dental arch for supporting the appliance and for applying force to the patient's anterior teeth, the lingual component operating to move the anterior teeth against the anterior portion of the labial component which serves as a reference against which the teeth are positioned.

Abstract: An orthodontic appliance including labial and lingual bodies having teeth-contacting surfaces for acting against targeted anterior teeth of a patient and associated labial and lingual components incorporating spring-loaded biasing means for causing the labial and lingual bodies to act in generally opposed directions and in unison against the surfaces of the targeted anterior teeth. Bands for attaching the appliance to molars and a lingual support component also are provided. The foregoing is applied to a fixed spring aligner, a habit appliance and a bonded crossbite appliance, as well as appliances having new and improved labial and lingual components. The habit appliance includes a labial component to pull anterior teeth into an ideal position, and the aligner and crossbite appliances include labial and lingual components for applying corrective forces to the respective labial and lingual surfaces of the anterior teeth.
