Abstract:
Bracket (1) with a pad (3) for affixing it to a tooth of a patient, with a bracket body (5) that has a slot (7) for receiving an orthodontic wire (9), and with a channel-like wire guide (11) which has wire guide surfaces (11F) for guiding the wire (9) and which is assigned a lateral insertion area (13) for insertion of the wire (9) into the wire guide (11), wherein the insertion area (13) has, in the longitudinal direction of the wire (9), a curved section (13A) through which the wire (9) can be inserted into the wire guide (11) in an elastically deformed state, such that the wire (9), on forming back to a rectilinear state, locks in the wire guide (11), and that the wire guide surfaces (11F) enclose the wire (9) in a circle shape, such that the wire (9) is held longitudinally displaceably in the wire guide (11) by the wire guide surfaces (11F) and is secured against escaping laterally from the wire guide (11).
