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. Sirney, Todd I. Oda

Publication number: 20100129765Abstract: An orthodontic apparatus includes an orthodontic bracket and an orthodontic member removably coupled thereto. The orthodontic member includes an engaging member configured to engage a tie wing of the bracket in non-contact relation with the archwire such that the member exerts no active forces on the archwire. A bumper extends from the engaging member so as to cover a side of the bracket and thereby prevent or reduce contact between the bracket and opposing teeth. The orthodontic member may include a support pad and/or nubs for limiting movement of the member relative to the bracket. The orthodontic member may also include decorative elements for aesthetic purposes.Type: ApplicationFiled: November 19, 2009Publication date: May 27, 2010Applicant: ORMCO CORPORATIONInventors: Jason A. Mohr, Ronald J. Sirney

Patent number: 6328562Abstract: A bite correcting appliance for correcting an overbite or underbite condition of a patient includes upper attachment structure, lower attachment structure and a stretchable, close coil spring connected between the upper and lower attachment structures. The close coil spring exerts a pushing force on the lower jaw as the patient's mouth closes and is substantially non-prestressed or non-preloaded. At least one end of the appliance includes a deformable or crimpable portion allowing selective locking and unlocking to the corresponding attachment structure. Upper and lower attachment members are connected with the close coil spring by both threading and crimping to the spring.Type: GrantFiled: September 1, 2000Date of Patent: December 11, 2001Assignee: Ormco CorporationInventors: Ronald J. Sirney, Craig A. Andreiko
