Publication number: 20200121421Abstract: Apparatus, system, and methods for utilizing one or more computing devices to stage the movement of teeth during an alignment treatment are disclosed. The computing device receives an electronic representation of the patient's teeth in their initial position and an electronic representation of the teeth a final position for each tooth. A route each tooth will travel to reach its final position is determined, and the teeth are scheduled to move according to a movement pattern. Moreover, the schedule of movement takes into account a maximum rate of tooth movement for each tooth, the path of movement for each tooth, the distance each tooth needs to move, any needed tooth staggering, any needed round-tripping or tooth movement slowing. The invention also includes techniques for determining an optimum number of stages for the treatment based on the schedule of movement.Type: ApplicationFiled: December 20, 2019Publication date: April 23, 2020Inventors: Ian Kitching, Alexander Dmitriev, Alexey Vishnevskiy

Patent number: 10383704Abstract: A method for fabrication of an orthodontic device having tooth-fitting cavities, such as an aligner, using layer-by-layer printing of a single or multiple polymeric materials. The cavities of the appliance or an appliance mold are defined by the boundaries of the multiple layers, encapsulating up to fourteen teeth of a patient, and shaped to apply a load to at least one tooth that is sufficient to cause movement of the tooth, and remodeling of the adjacent bone. In the case where the cavities form an appliance mold, the mold is used to form a positive model and an appliance is formed thereon. A series of such appliances may be used to treat malocclusion of teeth, each appliance used in series to incrementally move one or more teeth from initial positions toward a desired final position. The appliance may be fabricated with a variety of disclosed materials, and may include auxiliary features for interaction with other orthodontic elements.Type: GrantFiled: January 10, 2013Date of Patent: August 20, 2019Assignee: Ormco CorporationInventor: Ian Kitching

Publication number: 20180165818Abstract: A method for registering imageries of a tooth includes integrating imageries to roughly register two imageries. The method includes cross-sectioning the imageries through the tooth and moving one imagery relative to another one. Moving includes at least one of rotating and translating an imagery and may be relative to a characteristic feature of the tooth in the imagery. The tooth may be an anterior tooth, such as an incisor. Cross-sectioning may be at the characteristic feature in a sagittal plane, a transverse plane, and a coronal plane. And, moving may include at least one of rotating and translating the second imagery on a plane-by-plane basis in each plane. The method may include evaluating an error in the position of the imageries and repeating moving the imageries. A dental registration system includes a first imaging system and a second imaging system to capture different imageries of the teeth.Type: ApplicationFiled: November 17, 2017Publication date: June 14, 2018Inventors: Evan Yifeng Tsai, Ian Kitching
