Claim:
Self-ligating orthodontic bracket comprising: a support body ( 6 ) having a base ( 7 ) adapted to be fixed onto a tooth, a first slot defined by flat and straight walls, and an access channel ( 20 ) communicating with said first slot ( 9 ), wherein said access channel ( 20 ) is arranged crossing a receiving direction (X) in a direction (Y) slanted at an angle with respect to direction (X) so as to receive therein an arch wire ( 5 ) to impart to the tooth a corrective action when inside said first slot ( 9 ); a retaining element ( 10 ) adapted to engage said arch wire ( 5 ) along at least one engaging direction (Z) so as to maintain said arch wire ( 5 ) inside said slot ( 9 ); said retaining element ( 10 ) having at least one lug ( 10 ′) formed as a unit with said support body ( 6 ) which at least partially delimits and has an inner surface facing said first slot ( 9 ), said inner surface engaging said arch wire ( 5 ) in said engaging direction (Z) by a retaining portion ( 11 ) on said inner surface of said lug ( 10 ′), said lug ( 10 ′) defining said access channel ( 20 ) in a fixed angle relative to said slot; wherein the arch wire is a form-memorizing superelastic wire introduced through said access channel by deformation to reach said slot; and wherein said arch wire is retained by the retaining portion of said lug without requiring the movement of the lug; said self-ligating orthodonic bracket in use being free of retaining ligatures.
