1. A method for manufacturing a shape forming fixture for setting a shape of an orthodontic appliance, the orthodontic appliance being configured to be secured to a plurality of brackets on a patient's teeth, the method comprising:
obtaining a treatment planning digital model characterizing the patient's teeth and the brackets on the patient's teeth in planned positions;
obtaining a current tooth arrangement digital model characterizing the patient's teeth and the brackets on the patient's teeth in actual positions after the brackets have been bonded to the patient's teeth;
for each bracket, determining a difference between a respective actual position of the bracket and a respective planned position of the bracket;
based on the determined difference, creating a shape forming fixture digital model, the shape forming fixture digital model comprising a plurality of securing portions positioned relative to one another to reflect the actual positions of the brackets; and
forming a physical shape forming fixture based on the shape forming fixture digital model.
