Patent ID: 7264468

Claim:
An edgewise orthodontic bracket comprising, a horizontally opening archwire slot having directly opposed gingival and occlusal parallel means and, as viewed from the mesial or distal, defining a predetermined torque value and adapted to receive and coact with a main aligning rectangular archwire retained in said slot for controlling the directional movement of the bracket, an archwire coacting with said gingival and occlusal parallel means of said archwire slot, said archwire being slightly occlusogingivally undersized to said slot by at least 0.001 inch, and a mesiodistally extending tunnel or lumen separate from and occlusogingivally inclined to said archwire slot, said tunnel adapted to receive a relatively small flexible wire for applying a force to the bracket such as to cause diagonally opposed areas of the gingival and occlusal means of said slot to substantially engage the gingival and occlusal surfaces of the archwire to cause the bracket to rotate about the long axis of the archwire until the diagonally opposed areas of the slot engage and square up with the gingival and occlusal surfaces of the archwire.
