Abstract: Methods and systems are provided repositioning teeth of a patient, which employ at least one appliance specific to the patient for placement in the patient's mouth during use. The at least one appliance includes a polymeric shell having a cavity shaped to receive teeth of the upper jaw of the patient. The polymeric shell is integral to a polymeric segment shaped to cover the hard palate of the upper jaw of the patient. The geometry and material properties of the shell is configured such that the appliance adjusts position of the teeth of the upper jaw of the patient during use. The geometry and material properties of the segment is configured such that the appliance adjusts position of the hard palate of the upper jaw of the patient during use.
