<p>An orthodontic bracket (10) having a bracket body (12) configured to be mounted to a tooth (23) includes an archwire slot (16) having a base surface (40) defining a base plane (58) and a slide engagement track (48, 50, 52, 54) defining a transition plane (60). The translation plane (60) is angled with respect to the base plane (58). A ligating slide (14) is engaged with the slide engagement track (48, 50, 52, 54) of the bracket body (12) and movable along the slide engagement track (48, 50, 52, 54) and parallel to the translation plane (60) between an opened position, in which an archwire (18) is insertable into the archwire slot (16), and a closed position, in which the archwire (18) is retained within the archwire slot (16). The transition plane (60) is angled with respect to the base plane (58) so as to prevent the ligating slide (14) from contacting the gingiva (61) surrounding the tooth (23) when the ligating slide (14) is moved to the opened position.</p> |
