Patent number: 11957536Abstract: Hybrid orthodontic archwire designs are disclosed. Hybrid archwires may have bracket-archwire sections and interproximal archwire sections in which each section can vary in cross-section shape, size, and/or material properties. Bracket-archwire sections may be configured to promote torque control and may have rectangular cross-sections. Interproximal archwire sections may be configured to be bent into force-promoting loops and may have round cross sections. Each archwire section may be straight or bent into any shape. Hybrid archwires may have sliding sections and non-sliding sections. Non-sliding sections may have male connectors configured to prevent the archwire from sliding relative to the orthodontic brackets and/or may have cross-sectional shapes, sizes, or coatings that resist sliding relative to sliding sections. Sliding sections may have linear archwire segments. Hybrid archwires may have distal or posterior non-sliding sections and an intermediate anterior or medial sliding section.Type: GrantFiled: November 25, 2020Date of Patent: April 16, 2024Assignee: Swift Health Systems Inc.Inventors: Hongsheng Tong, Philong John Pham, Allen Huynh, Robert Lee

Patent number: 11911971Abstract: Systems and methods for fabricating indirect bonding trays are disclosed. Physical models of a patient's teeth can be created with non-functional placeholder brackets, impressions of which can be transferred to indirect bonding trays. This can create wells in which functional brackets can be placed into, reducing errors created from transferring functional brackets from the physical model onto the indirect bonding trays.Type: GrantFiled: March 20, 2023Date of Patent: February 27, 2024Assignee: Swift Health Systems Inc.Inventors: Hongsheng Tong, Robert Lee, Philong John Pham, Allen Huynh

INDIRECT BONDING TRAYS, NON-SLIDING ORTHODONTIC APPLIANCES, AND REGISTRATION SYSTEMS FOR USE THEREOF
Publication number: 20240058101Abstract: Non-sliding orthodontic appliances may include an archwire having male fasteners for locking in place with brackets in a non-sliding manner and interproximal loops for exerting forces on the brackets. Appropriate forces may be calculated according to vectors between initial and ideal tooth positions. The brackets may be transferred to a patient's teeth using indirect bonding trays which contain slots for holding and aligning each bracket. The trays may include integrated handles for facilitating handling, may be sectioned into smaller pieces for easier application, and/or may be labeled for facilitating proper registration. Superposition of a digital placement plan and clinical model after bonding may illustrate the accuracy of bracket placement. The archwire may comprise atraumatic ends to avoid patient discomfort. A color registration system can be used to facilitate the attachment of the archwire to the brackets. The archwire may be locked into place with the brackets using crimpable stops.Type: ApplicationFiled: June 19, 2023Publication date: February 22, 2024Inventors: Hongsheng Tong, Philong John Pham, Allen Huynh, Robert Lee, Vijay Dhaka -

Patent number: 11612458Abstract: Disclosed herein are devices, systems, and method for preconditioning lingual tissue for lingual orthodontic treatment, including the application of lingual braces. Protuberances may be affixed to the lingual surfaces of one or more of a patient's teeth prior to the introduction of an orthodontic appliance to allow time for the tongue to adapt to the presence of foreign structures. The protuberances may promote keratinization of the lingual tissue. The protuberances may be removed prior to the application of the orthopedic appliance. The protuberances can be pre-fabricated or fabricated in situ on the surfaces of the teeth. The protuberances may be any suitable material, including metal, polymer, or ceramic.Type: GrantFiled: March 30, 2018Date of Patent: March 28, 2023Assignee: Swift Health Systems Inc.Inventors: Hongsheng Tong, Philong John Pham, Allen Huynh, Robert Lee, Vijay Dhaka

Patent number: 11517405Abstract: An orthodontic appliance may include an archwire and multiple orthodontic brackets. The archwire may fit within a human mouth and contain multiple male connectors. Each orthodontic bracket may have a configuration that facilitates attaching the orthodontic bracket to a single tooth. Each orthodontic bracket may allow one of the male connectors to be locked into the orthodontic bracket with a snapping action. The male connector may be unable to slide with respect to the orthodontic bracket after being locked in the orthodontic bracket. A manual unlocking action may allow the male connector to disengage from the orthodontic bracket.Type: GrantFiled: October 13, 2021Date of Patent: December 6, 2022Assignee: University of Southern CaliforniaInventors: Behrokh Khoshnevis, Hongsheng Tong, Yong Chen, Philong John Pham, Robert Lee
