Abstract:
A preadjusted orthodontic bracket system for applying torque force to a selected tooth. The system comprises an archwire of substantially rectangular cross-section having first and second side dimensions and a bracket configured to be attached to the selected tooth and including a substantially rectangular slot which edgewise receives the archwire, the slot having a predetermined width and being formed in the bracket at a built-in torque angle. The smaller of the first and second side dimensions of the archwire is less than full-size for the width of the bracket slot and the built-in torque angle of the slot is greater than a full expression of a target torque angle recommended for the tooth by a selected one of the Roth, Andrews, Alexander, Hilgers, Bench, Ricketts, Cetlin and other known preadjusted orthodontic techniques. The archwire and preadjusted bracket, in combination, apply force to the tooth at an actual torque angle which substantially corresponds to the target torque angle recommended for the tooth by the selected orthodontic technique.
