Methods of orthodontic treatment using localized energy

A method of modifying an orthodontic treatment, the method comprising:

• receiving one or more images of a patient's teeth during a stage of the orthodontic treatment, wherein the orthodontic treatment includes the use of a plurality of dental appliances each shaped to incrementally adjust a position of one or more of the patient's teeth according to a treatment plan;
• comparing a current virtual model of the patient's teeth based on the one or more images to a target virtual model of the patient's teeth;
• determining that one or more of the patient's teeth are off track based on one or more discrepancies between the current virtual model and the target virtual model;
• and
• modifying a subsequent stage of the treatment plan by implementing local energy radiation to a region of the patient's dental arch using a subsequent dental appliance of the plurality of dental appliances that correspond to the subsequent stage of the treatment plan, wherein the local energy radiation is configured to accelerate repositioning of the one or more of the patient's teeth and to put the one or more of the patient's teeth on track according to the treatment plan.
