Orthodontic Bracket

US Patent:
2012012, May 17, 2012
Filed:
Jan 3, 2012
Appl. No.:
13/342582
Inventors:
Juergen Bathen - McMinnville OR, US
Raphael L. Greenfield - Delray Beach FL, US
Rolf Hagelganz - Dundee OR, US
International Classification:
A61C 7/34
US Classification:
433 14
Abstract:
An orthodontic bracket mountable on a tooth for use in retraction mechanics to facilitate movement of teeth along an arch, which includes an archwire-receiving member rotatably mounted on a base and structured to freely rotate when tipping a tooth during sliding of the bracket along an archwire thereby minimizing friction between the archwire and bracket to significantly decrease the required retraction force, and treatment time, thereby minimizing the possibility of root resorption and maintaining the integrity of the root and surrounding bone. A locking pin for locking the member against rotation is employed when uprighting the tooth from a tipped position.
