METHODS OF FORMING SHAPE ENGINEERED ORTHODONTIC APPLIANCES

Abstract:

The present disclosure relates to shape engineered orthodontic appliances and methods for fabricating the same. Methods of the present disclosure may comprise modifying a first representation of a patient's teeth, wherein the modified representation compensates for a non-elastic deformation resulting from use or wear of the orthodontic appliance. Methods may further comprise defining teeth receiving cavities on the orthodontic appliance, wherein the teeth receiving cavities are shaped to receive and apply a resilient positioning force to the patient's teeth. Methods may also comprise defining exterior portions on the orthodontic appliance using the modified representation of the patient's teeth.
