Abstract
Aligners and orthodontic systems are provided. In some embodiments, an aligner includes a polymeric shell including a plurality of tooth-receiving cavities, an interior layer, and an exterior layer. The exterior layer can comprise a discontinuity formed therein. When the aligner is worn on a patient's teeth, the interior layer can interact with the discontinuity to impart one or more forces to facilitate repositioning of the patient's teeth.
