Methods and systems for treating teeth

摘要

A system for repositioning teeth comprises a plurality of individual appliances used with braces. The appliances are configured to be placed successively on the patient's teeth and to incrementally reposition the teeth from an initial tooth arrangement, through a plurality of intermediate tooth arrangements, and to a final tooth arrangement. The appliances may be substituted with braces as appropriate to optimize the treatment of the teeth.

主权项

1. A system for determining a treatment plan for repositioning a patient's teeth from a first arrangement to a target arrangement, the system comprising:
a processor; a display device coupled to the processor; and a data storage device coupled to the processor, the data storage device storing instructions executable by the processor to cause the system to:
receive a digital data set comprising a digital model of the patient's teeth in a first arrangement for determining a severity of a malocclusion of a patient;generate, based on the determined severity of the patient's malocclusion, a first treatment plan having data comprising a plurality of intermediate digital data sets each corresponding to a different successive tooth arrangement for repositioning the patient's teeth from the first arrangement toward a target arrangement, the treatment plan prescribing a first phase and a second phase in a pre-selected order, the first phase comprising successively placing polymeric shell appliances having tooth receiving cavities having different geometries selected to progressively reposition the teeth, the second phase comprising placing a wire and bracket system to progressively reposition the teeth;receive evaluation data indicating whether repositioning of the teeth is progressing in a satisfactory fashion after the patient has been administered at least some of the polymeric shell appliances; andgenerate a second treatment plan data in response to the evaluation data, the second treatment plan comprising a prescribed schedule for transitioning between administering to the patient polymeric shell appliances as in the first phase of the first treatment plan and placing a wire and bracket system to progressively reposition the teeth as in the second phase of the first treatment plan.
