ABSTRACT:
Fabricating polymeric shell appliances for moving a patient's teeth. A first tooth arrangement model is formed by placing models of individual teeth representing the patient's teeth onto a plurality of platforms of a frame approximating a shape and size of a jaw of the patient, wherein each model tooth comprises a coupling member for coupling the model tooth with a platform of the plurality of platforms. A first polymeric shell appliance is formed over the first tooth arrangement model or a copy thereof. At least a second tooth arrangement model is formed by rearranging at least some of the individual teeth relative to the frame. At least a second polymeric shell appliance is formed over the second tooth arrangement model or a copy thereof.
