a hook, extending from and integrally formed as a single piece with the curved rod, on a rod portion away from an anterior end of the canine tooth during treatment, for attachment to a traction elastic, the hook located between the canine attachment bracket and the molar tube;
wherein the distal end of the curved rod engages at least one surface of the molar tube to exert a distal force and a partly rotational force on the molar tooth when under a force of the traction elastic on the hook; and the curved rod is curved in the in the buccal-lingual plane.
