The invention relates to a method for producing a set of shell appliances for correcting tooth misalignments in a patient, wherein a target position is established from a current position of the patients teeth, models of the patients individual teeth or of groups of the patients teeth are produced and can be arranged on a support to form a model of a set of teeth. In accordance with the invention, a set of supports is produced, which have a respective fitting position for each of the tooth models, the position and alignments of said fitting positions predefining a position of the tooth model, wherein the positions predefined by the supports form a sequence that leads in steps to the target position, and the tooth models are fitted in succession onto the individual supports, thus producing a respective model of a set of teeth, and a shell appliance is produced from each of these models of a set of teeth by thermoforming.
