DENTAL ALIGNERS, PROCEDURES FOR ALIGNING TEETH, AND AUTOMATED ORTHODONTIC TREATMENT PLANNING

摘要

A method, system, and apparatus for orthodontic treatment planning to align a patient's teeth, and dental appliance devices for aligning the patient's teeth based on the method. The method comprises performing pre-staging to evaluate a patient's general oral and periodontal health. Additionally, the method comprises performing a lower arch stage of treatment planning to define movement of at least one tooth of a lower arch, performing an upper arch stage of treatment planning to define movement of at least one tooth of an upper arch, and performing a final arch stage of treatment planning to define articulation of the lower and upper arches. At least one stage is based on a predetermined prior treatment plan. Dental appliances can be fabricated having geometries determined based on at least one stage. Patient wear of successive dental appliances manipulates the patient's teeth to a final, aligned teeth arrangement, as planned by the method.
