Patent ID: 8636508

Claim:
A self-ligating bracket for orthodontics comprising: a base, an occlusal wall extending from the base and having at least one occlusal ligature wing, a gingival wall extending from the base and having at least one gingival ligature wing, a slot, which separates the occlusal wall and the gingival wall from one another and extends continuously in a direction from mesial to distal, a slide, which is held in a guide provided in the occlusal wall and/or in the gingival wall, and in the guide can be shifted in a gingival-occlusal direction between a closed position, in which the slide bridges the slot, and an open position, in which the slot is open in a labial direction, an elongated recess provided in the gingival wall or in the occlusal wall of the bracket and having an opening facing the slide, wherein a longitudinal direction of the elongated recess runs parallel to a longitudinal direction of the slot, and a structure, that can hold the slide in the closed position as well as in the open position, wherein: the structure that can hold the slide comprises a strand, wherein the strand is elastically and elastomerically unyielding, the strand having a cylindrical lateral surface wherein the strand is arranged horizontally in the recess, the strand having a part of the lateral surface facing towards the slide and another part of the lateral surface facing towards the base, is supported in the recess and rests on an elastically or elastomerically yielding plug with the part of the lateral surface facing towards the base and can give way to a movement of the slide because the plug can be elastically or elastomerically deformed by the moving slide; a first stop is provided on the slide, which abuts the lateral surface of the strand in the open position of the slide; on a side of the slide that faces the strand a protrusion is provided on said slide and arranged in such a way that upon displacement of the slide into the closed position, before assuming the closed position, it first abuts the lateral surface of the strand, before the slide can assume the closed position, by the protrusion passing the strand and deforming the elastically or elastomerically yielding plug while passing the strand; sufficient space is available on opposite sides of the protrusion, in order to accommodate a section of the strand protruding from the elongated recess; a second stop is provided on the bracket and the slide abuts said second stop in the closed position, once the protrusion has passed the strand.
