Patent number: 10799324Abstract: An orthodontic bracket for coupling an archwire with a tooth includes a bracket body that has an archwire slot adapted to receive the archwire. A movable member is engaged with the bracket body and is movable between an opened position and a closed position. The bracket body and movable member are made from a transparent or translucent ceramic for improved aesthetics. The bracket body may include one or more stop surfaces that limit movement of the moveable member in the gingival direction. The bracket body may include a support surface that is positioned lingually of a labial edge of the archwire slot. The moveable member may include a bracket-engaging portion having a first surface confronting the bracket body and a slot-covering portion having a second surface confronting the archwire slot, the first and second surfaces being offset from one another.Type: GrantFiled: September 27, 2013Date of Patent: October 13, 2020Assignee: Ormco CorporationInventors: Jonathan Yeh, Rodolfo Rodriguez, Farrokh Farzin-Nia

Publication number: 20180042700Abstract: An orthodontic bracket includes a bracket body and a ligating member. The ligating member retains an archwire in an archwire slot and includes archwire control structure including projecting portions spaced apart in a mesial-distal direction with a recessed area therebetween. The recessed area and the projecting portions overlie the archwire slot. The recessed area may include a flat or a curved surface in a mesial-distal direction. The recessed area and projecting portions may define a radius of curvature that is less than the radius of curvature of the archwire seated in the slot. The archwire contacts one or both the projecting portions resulting in a larger moment arm and better rotational control of the bracket with the force applied by the archwire.Type: ApplicationFiled: October 26, 2017Publication date: February 15, 2018Inventors: Albert Ruiz-Vela, Farrokh Farzin-Nia, Ronald J.

Patent number: 9827073Abstract: A self-ligating orthodontic bracket for captivating an archwire with a tooth. The bracket includes a bracket body mountable to a tooth and a self-ligating mechanism having an archwire slot and a ligating slide. The ligating slide is movable between an open position in which an archwire is insertable into the archwire slot and a closed position in which the archwire is retained in the archwire slot. The bracket body may be formed from a non-metallic material, such as a polymer, a filled polymer composite, or a ceramic, and the self-ligating mechanism may be formed from a metal. The bracket may include a resilient engagement member with a detent positioned to engage an aperture or throughhole extending through the ligating slide when the ligating slide is in the closed position.Type: GrantFiled: September 27, 2013Date of Patent: November 28, 2017Assignee: Ormco CorporationInventors: Farrokh Farzin-Nia, Albert Ruiz-Vela

Patent number: 8672676Abstract: An archwire assembly comprises an archwire with a crimpable sleeve adapted to slidably move along the archwire so as to be positioned between two adjacent brackets of orthodontic braces. The archwire assembly further includes a stop applied to the archwire and adapted to limit the movement of the sleeve along the archwire. The stop may include removable stops where the sleeve is movable along the archwire between the stops. The removable stops may be movable along the archwire with the application of a sufficient force. The stop may also include a friction-creating substance applied to either the sleeve or the archwire such that it takes a sufficient force to move the sleeve along the archwire. The stop may also include a partially crimped sleeve applied to the archwire such that it takes a sufficient force to move the sleeve along the archwire.Type: GrantFiled: May 21, 2012Date of Patent: March 18, 2014Assignee: Ormco CorporationInventors: Farrokh Farzin-Nia, Todd I.
