<p>An improved orthodontic bracket (10, 50, 62, 70, 80, 96, 114, 128) including a horizontally opening archwire slot (22, 93) for a main aligning archwire (23, 118) for allowing crown tipping, limiting root uprighting, and controlling torquing, and a relatively small horizontal uprighting slot, tunnel or lumen (35, 54, 63, 72, 98, 120, 122) extending substantially mesiodistally for receiving an additional small wire (38, 90) for uprighting teeth and eliminating the need to use individual uprighting springs in the final stage of patient treatment.</p> |
