Abstract
Methods and apparatus fit a set of upper and lower teeth in a masticatory system by generating a computer representation of the masticatory system and computing an occlusion based on interactions in the computer representation of the masticatory system.
Claims78
A method for fitting a set of upper and lower teeth in a masticatory system of a patient, comprising:
- providing a static occlusion determined from a computer representation of the masticatory system;
- modeling an ideal set of teeth;
- automatically updating the computer representation of the masticatory system of the patient based on the ideal set of teeth;
- and
- optimizing the position of the patient's teeth to fit the ideal set of teeth;
- and
- generating a plurality of appliances having cavities, said appliances having cavities 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.
4 more elements
A method for fitting a patient's teeth, comprising:
- scanning the teeth to generate a computer representation of the teeth;
- determining an occlusion from the computer representation of the teeth;
- generating a plurality of appliances for the teeth in response to the determined occlusion, wherein the appliances comprise shells having cavities and wherein the cavities of successive ones of the shells have different geometries shaped to receive and resiliently reposition teeth from one arrangement to a successive arrangement.
