Patent number: 11331166Abstract: 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.Type: GrantFiled: July 25, 2018Date of Patent: May 17, 2022Assignee: Align Technology, Inc.Inventors: John Y.

Patent number: 11284976Abstract: To provide a pair of maxillary and mandibular coupled artificial tooth sets applicable to alveolar ridge shapes of an unspecified large number of edentulous patients and having all the parts of 14 teeth coupled into an ideal arch shape and in an ideal maxillomandibular occlusal contact relationship. The present invention provides a pair of maxillary and mandibular coupled artificial tooth sets clearly defining an arrangement region of all parts at the time of arrangement in virtual three-dimensional coordinates, a contact relationship between maxillary and mandibular artificial teeth, and a harmonizing contact/gliding relationship at the time of movement on a mean-value articulator. This enables provision of a high-quality complete denture in which an occlusal relationship required for a complete denture can be established in a short time regardless of a skill of a technician and a difference in shape of an alveolar ridge of an edentulous patient.Type: GrantFiled: May 7, 2019Date of Patent: March 29, 2022Assignee: KABUSHIKI KAISHA SHOFUInventors: Nobutaka Watanabe, Katsushi Tamaki, Kunihiro Fujii, Hirokazu Satoh, Toshiyuki Nakatsuka
