Claims24
A method for fitting a set of upper and lower teeth in a masticatory system of a patient, comprising:
- modeling a set of teeth in a predetermined position;
- and
- generating a plurality of one or more appliances having cavities, said appliances having cavities and wherein the cavities of successive ones of the plurality appliances have different geometries shaped to receive and resiliently reposition teeth from one arrangement to a successive arrangement.
A method for fitting a set of upper and lower teeth in a masticatory system of a patient, comprising:
- modeling a set of teeth in three or more predetermined positions;
- and
- generating an appliance having cavities for each of the three or more predetermined positions, said appliance having cavities and wherein the cavities of successive ones of the plurality appliances have different geometries shaped to receive and resiliently reposition teeth from one arrangement to a successive arrangement.
A method for fitting a set of upper and lower teeth in a masticatory system of a patient, comprising:
- modeling a set of teeth using three or more predetermined molds or casts;
- and
- generating an appliance having cavities for each of the three or more molds or casts, said appliance having cavities and wherein the cavities of successive ones of the plurality appliances have different geometries shaped to receive and resiliently reposition teeth from one arrangement to a successive arrangement.
