Publication number: 20210212803Abstract: 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: ApplicationFiled: November 25, 2020Publication date: July 15, 2021Inventors: Hongsheng Tong, Philong John Pham, Allen Huynh, Robert Lee

Indirect bonding trays, non-sliding orthodontic appliances, and registration systems for use thereof
Patent number: 11058517Abstract: 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: GrantFiled: April 19, 2018Date of Patent: July 13, 2021Assignee: Swift Health Systems Inc.Inventors: Hongsheng Tong, Philong John Pham, Allen Huynh, Robert Lee, Vijay Dhaka -
Patent number: 11058520Abstract: 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: March 7, 2019Date of Patent: July 13, 2021Assignee: University of Southern CaliforniaInventors: Behrokh Khoshnevis, Hongsheng Tong, Yong Chen, Philong John Pham, Robert Lee

Publication number: 20210093422Abstract: 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: ApplicationFiled: September 21, 2020Publication date: April 1, 2021Inventors: Hongsheng Tong, Robert Lee, Philong John Pham, Allen Huynh

Publication number: 20200275996Abstract: An orthodontic indirect bonding tray that may transfer orthodontic brackets, bite turbo, and/or orthodontic auxiliaries is disclosed. The indirect bonding tray may be digitally designed and 3D printed or fabricated based on a bonding model. The indirect bonding tray may transfer the orthodontic brackets, bite turbos, and orthodontic auxiliaries to any tooth surface. The indirect bonding tray may be designed to transfer bite turbos that vary in size, shape, and the amount of bite opening or functional correction.Type: ApplicationFiled: February 28, 2020Publication date: September 3, 2020Inventors: Hongsheng Tong, Robert Lee, Andre Weissheimer

Patent number: 10744070Abstract: A gastrointestinal administration device comprising an elongated tube or track, an anchor and a channel, which allows the proximal end of the tube or track to be wholly secured inside the mouth from where it passes down the lateral oropharynx to the desired site in the gastrointestinal tract. This system may be used to administer nutrients, fluids, medications, nutraceuticals, dietary supplements and/or non-nutrient gastrointestinal stimulants or other therapies directly to a desired site in the gastrointestinal tract in humans and animals for a variety of purposes including novel applications such as weight and glucose control, local administration of medication and storage of a deposit of a therapeutic agent. It may also be used for monitoring of processes inside the gastrointestinal tract.Type: GrantFiled: June 17, 2016Date of Patent: August 18, 2020Inventors: Elizabeth Demetriades, Philong Pham, Behrokh Khoshnevis, Hongsheng Tong
