Patent ID: 10813722

Abstract:
An orthodontic bracket is provided including a hollow housing defining a cavity and having windows for accessing the cavity to allow an archwire to pass through the housing. One or more, and preferably at least two sets of rollers are provided within the hollow housing for reducing the friction on the archwire as it passes through the windows and the cavity of the housing. The orthodontic bracket preferably includes a first set of rollers located adjacent a first or entrance window and a second set of rollers located adjacent a second or exit window. Guide blocks are provided between the sets of rollers to prevent the archwire from kinking or binding within the housing. A mounting block or mesh pad is provided on a rear of the housing to attach the housing to a tooth and a cover is provided on a front of the housing to secure the sets of rollers within the housing. An external hook may be provided on the housing for attaching rubber bands or other tensioning devices to the orthodontic bracket.
