Abstract: Self-ligating bracket for orthodontics has a base, an occlusal wall extending from the base and occlusal ligature wing, a gingival wall extending from the base and gingival ligature wing, a slot, which separates the occlusal wall and the gingival wall from one another and extends continuously in the direction from mesial to distal, and a slide, which is held in a guide provided in the occlusal wall and/or in the gingival wall. The guide can be shifted in the 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 labial direction. A structure holds the slide in its closed position as well as in its open position.

Abstract: The invention relates to an orthodontic tool for opening a self-ligating bracket, having a body (10) which carries on its end a tappet (12) for displacing a clamp (5) of the bracket out of its closed position and into its open position, an annular groove (13) being situated between the tappet and the body, in which an upper edge of the bracket engages in displacement of the clamp (5) out of its closed position and into its open position between the tappet (12) and the body (10) for axial positioning of tappet (12) with respect to the bracket to be opened.

Abstract: An orthodontic expansion screw having two bodies whose distance from each other can be changed by means of a spindle that engages both bodies. The spindle includes an actuation part for effecting a torque for readjusting the spindle, and a straight-line guide for engaging both bodies and guiding the bodies along two guide axes that are parallel to each other while preventing a relative rotation of the bodies when their distance from each other is being changed. A friction brake is provided that presses onto the actuation part of the spindle and thus generates a frictional force that renders a rotation of the spindle in both directions of rotation more difficult in order to prevent inadvertent readjustment of the spindle.

Abstract: A self-ligating bracket for use in orthodontics includes a bracket also closeable by a slide which is undetachably held in both a closed position and in an open position. The slide is easy to open and to close, which gives the bracket an acceptably attractive appearance and which provides little risk of food residues getting trapped that are difficult to remove.

Abstract: Then invention relates to an orthodontic bracket comprised of a base (2) for the fastening on a tooth and a bent yoke (3a) that can swivel between an open position, in which between the base (2) and a free end of the yoke (3a) is space for the inserting of a wire (4), and a closed position in which the yoke (3a) embraces an inserted wire (4), that is then held between said yoke and the base. Pursuant to the invention it is provided that on the base (2) is fastened a holding tongue (5) for the twisting-resistant holding of a wire (4) embraced by the yoke (3a).
