Abstract
A method that generally relates to comparing a current dental setup with a series of preset dental setups. More particularly a method where this comparison is used to determine which aligner should be used from a series of dental aligners for proceeding with an orthodontic treatment. Each aligner in the series of previously manufactured aligners is provided for moving the at least one tooth in the patient's teeth from one dental setup to a subsequent dental setup.
Claims5
A method for selecting an aligner from a series of previously manufactured aligners for moving at least one tooth in a patient's set of teeth from an initial dental setup to a final dental setup via a sequence of intermediate dental setups, and where each aligner in the series of previously manufactured aligners is provided for moving the at least one tooth in the patient's teeth from one dental setup to a subsequent dental setup,
- wherein the method comprises a digital workflow for:
- obtaining a digital 3D representation of a patient's set of teeth,
- obtaining a digital treatment plan comprising an initial dental setup, an expected current dental setup and at least two intermediate dental setups representing the dental setup between the initial dental setup and the expected current dental setup and where at least two aligners are provided in the series of previously manufactured aligners for moving the at least one tooth to the respective at least two intermediate dental setups, and
- digitally determine which of the at least two intermediate dental setups have a closest match to the digital 3D representation of a patient's set of teeth,
- wherein the method further comprises selecting an aligner from the series of previously manufactured aligners based on the closest match.
A computer implemented method for determining the correct stage of a planned treatment, wherein the method comprises:
- obtaining a digital 3D representation of a patient's set of teeth,
- obtaining a digital treatment plan comprising an initial dental setup, an expected current dental setup and at least two intermediate dental setups representing the dental setup between the initial dental setup and the expected current dental setup and where at least two aligners are provided in the series of previously manufactured aligners for moving the at least one tooth to the respective at least two intermediate dental setups, and
- digitally determine which of the at least two intermediate dental setups have a closest match to the digital 3D representation of a patient's set of teeth.
