Dental appliance with repositioning jaw elements

A non-transitory computing device readable medium storing instructions executable by a processor to cause a computing device to perform a method, the method comprising:

• scanning the patient's dentition with a scanner to form a virtual image of the patient's jaw;
• generating a virtual model of the jaw based on the virtual image;
• identifying a jaw position of a misaligned jaw of a patient from the virtual image of the patient's jaw;
• providing a treatment plan for the patient, the treatment plan including instructions to apply tooth repositioning forces to reposition at least one tooth of the patient and to apply jaw repositioning forces to modify the jaw position of the misaligned jaw;
• generate virtual representations of a first repositioning jaw element and a second repositioning jaw element;
• virtually modeling application of the jaw repositioning forces between the first repositioning jaw element and the second repositioning jaw element to obtain a virtual model of the application of the jaw repositioning forces on the virtual model of the patient's jaw;
• identifying one or more constraints limiting the application of the jaw repositioning forces to the misaligned jaw, based on the virtual model of the application of the jaw repositioning forces;
• and
• providing adjustment instructions to adjust the first repositioning jaw element and the second repositioning jaw element to accommodate the one or more constraints.
