Patent number: 11963842Abstract: Appliances for intraoral delivery of agents are provided. In some embodiments, an appliance includes a shell having an inner surface and an outer surface, the inner surface defining a plurality of tooth-receiving cavities configured to apply a repositioning force to a patient's teeth, and the outer surface oriented away from the patient's teeth. The appliance can also include a reservoir integrally formed in the outer surface of the shell, the reservoir being configured to store at least one agent. The appliance can further include a membrane covering at least a portion of the reservoir to control release of the agent into an intraoral cavity of the patient. The membrane can include a plurality of pores that are configured to open based at least in part on a temperature of the patient's intraoral cavity to allow the at least one agent to pass therethrough.Type: GrantFiled: July 15, 2022Date of Patent: April 23, 2024Assignee: Align Technology, Inc.Inventors: David Mason, Shiva Sambu, Chunhua Li, Yan Chen

Patent number: 11896457Abstract: Orthodontic positioning devices, and related methods and systems, are disclosed for use with one or more orthodontic elastic members. The disclosed methods may comprise determining the geometries for a pair of orthodontic aligners for use as part of an orthodontic treatment plan. The geometries for the pair of orthodontic aligners may include an upper aligner with a first marking and a lower aligner with a second marking. The first marking may correspond to a position of a first hook, and the second marking may correspond to a position of a second hook. The first hook and the second hook may be configured to engage with an orthodontic elastic member so as to react a force to, for example, generate orthodontic forces on the patient's teeth.Type: GrantFiled: March 1, 2023Date of Patent: February 13, 2024Assignee: ALIGN TECHNOLOGY, INC.Inventors: Eric Kuo, Artem Borovinskih, Shiva Sambu

The disclosed devices may comprise a pair of orthodontic aligners for use as part of an orthodontic treatment plan. The pair of orthodontic aligners may include an upper aligner with a first integrally formed hook and a lower aligner with a second integrally formed hook. The first integrally formed hook and the second integrally formed hook may be configured to engage with an orthodontic elastic member so as to react a force to, for example, generate orthodontic forces on the patient's teeth. Each of the first integrally formed hook and the second integrally formed hook may extend buccally from the upper aligner and the lower aligner, respectively.Type: GrantFiled: March 1, 2023Date of Patent: February 6, 2024Assignee: ALIGN TECHNOLOGY, INC.Inventors: Eric Kuo, Artem Borovinskih, Shiva Sambu

Patent number: 11890159Abstract: Orthodontic positioning devices, and related methods and systems, are disclosed for use with one or more orthodontic elastic members. The disclosed devices are configured to couple with an orthodontic elastic member so as to react a force from the elastic member into the appliance to, for example, generate traction forces on the patient's teeth to produce a desired occlusion. A positioning device includes a patient removable tooth positioning appliance having teeth receiving cavities shaped to receive and apply a resilient positioning force to a patient's teeth. The appliance includes a hook configured to interface with an orthodontic elastic member. The hook can be configured to be offset from a surface of a tooth when the appliance is coupled with the patient's teeth and no elastic member is coupled with the tooth. The hook can be curved so that the hook is more retentive on the aligner. The hook can be reinforced so that the reinforcement resists deformation when the elastic is in place.Type: GrantFiled: August 10, 2022Date of Patent: February 6, 2024Assignee: ALIGN TECHNOLOGY, INC.Inventors: Eric Kuo, Artem Borovinskih, Shiva Sambu

Publication number: 20230301753Abstract: The present disclosure provides method, systems, and devices for expanding arch of teeth. A device for expanding an arch of teeth of a patient can include a removable shell formed of a first material having a number of cavities formed therein. The number of cavities are shaped to receive teeth of a patient. A device for expanding an arch of teeth of a patient can include an arch element extending from the removable shell in a lingual direction and across an arch width of the removable shell. The arch element can be formed of the first material and a second material that is a different material than the first material, can be designed to expand an arch of the teeth of the patient, and can have a width specific to a stage of a treatment plan.Type: ApplicationFiled: March 27, 2023Publication date: September 28, 2023Inventors: Avi KOPELMAN, Shiva SAMBU, Rene M.

Publication number: 20230018058Abstract: A dental appliance having an integrally formed reservoir and/or an ornamental design integrated thereon. The ornamental design can be selected or customized by a patient. The design can be created by directing energy to the dental appliance to alter a material property of at least a portion of the appliance to create the design. Alternatively, a groove or recess can be formed on a surface of the appliance to either mechanically retain an ornamental design or the groove or recess can be filled with ink to form the design. The appliance, including the integrally formed reservoir, can be formed using direct fabrication techniques.Type: ApplicationFiled: July 15, 2022Publication date: January 19, 2023Inventors: David MASON, Shiva SAMBU, Chunhua LI, Yan CHEN
