Appl. No.:

17/727393

Inventors:

- San Jose CA, US

Juan Carlos Alvarez - Watsonville CA, US

International Classification:

A61C 7/36
A61C 7/00
A61C 7/08

Abstract:

A set of stabilizer aligners includes an upper stabilizer aligner for an upper dental arch of a patient and a lower stabilizer aligner for a lower dental arch of the patient. The upper stabilizer aligner comprises a first set of cavities that conform to a dentition of the upper dental arch and a first set of stabilizing features. The lower stabilizer aligner comprises a second set of cavities that conform to a dentition of the lower dental arch and a second set of stabilizing features. Stabilizing features in the second set of stabilizing features are configured to contact opposing stabilizing features in the first set of stabilizing features. The upper stabilizer aligner and the lower stabilizer aligner prevent jaw movement of the patient while the upper stabilizer aligner is worn on the upper dental arch, the lower stabilizer aligner is worn on the lower dental arch, and the upper stabilizer aligner is engaged with the lower stabilizer aligner.

Abstract:

System and method for developing a treatment plan for achieving a treatment goal including creating a virtual model of a dental patient's dentition; transforming the virtual model of the dentition using virtual prosthodontics to facilitate achievement of the treatment goal; transforming the virtual model of the dentition using virtual orthodontics to facilitate achievement of the treatment goal; iterating on the transforming steps until substantially achieving the treatment goal; and generating an orthodontic treatment plan and a prosthodontic treatment plan based upon the substantially achieved treatment goal

International Classification:

Abstract:

Embodiments relate to aligners that are capable of immobilizing a patient's jaw after orthognathic surgery while also applying forces to reposition a patient's teeth. In embodiments, a processor determines, for a treatment stage, a dentition for an upper dental arch and a lower dental arch. The processor applies one or more stabilizing features to the upper dental arch and the lower dental arch. The processor determines whether the one or more stabilizing features will prevent jaw movement while the upper dental arch is engaged with the lower dental arch. Responsive to a determination that the one or more stabilizing features will prevent the jaw movement, the processor stores a first digital model comprising the dentition for the upper arch and the one or more stabilizing features for the upper arch and stores a second digital model comprising the planned dentition for the lower arch and the one or more stabilizing features for the lower arch for each increment of treatment.
