Systems, methods, and apparatus for correcting malocclusions of teeth

A system for manufacturing an orthodontic appliance, the system comprising:

• a processor;
• and
• memory including instructions that when executed by the process cause the system to:
• measure the positions of a patient's teeth;
• receiving tooth movement constraints;
• measure a first element of a patient's malocclusion of the patient's teeth for one or more types of dental malocclusions;
• generate a plurality of treatment plans based on the measured tooth positions and the tooth movement constraints;
• generate an first interim final position for each of the plurality of treatment plans;
• measure a second element of the patient's malocclusion in the first interim final position for a plurality of treatment plans;
• modify the first interim final position for each of the plurality of treatment plans to correct the element of the patient's malocclusion and generate a final position for each of the plurality of treatment plans;
• select a treatment plan from the plurality of treatment plans;
• generate a model of an appliance for each stage of the selected treatment plan;
• and
• output instructions for fabricating the appliance for each stage of the selected treatment plan based on the model of the appliance for each stage of the selected treatment plan.
