Abstract:
1. A bracket comprising: a pad for affixing to a tooth of a patient, the pad comprising an occlusal groove; a bracket body including a slot for receiving an orthodontic wire; and a wire guide offset from the slot in a generally apical-lingual or incisal-vestibular direction, the wire guide including wire guide surfaces for guiding the wire and a lateral insertion area comprising the occlusal groove, wherein the insertion area has, in the longitudinal direction of the wire, a curved section through which the wire can be inserted into the wire guide in an elastically deformed state, such that the wire, on forming back to a rectilinear state, locks in the wire guide, wherein the wire guide surfaces enclose the wire in a circular shape when viewed along the longitudinal axis of the wire, such that the wire is held in a longitudinally displaceable manner in the wire guide by the wire guide surfaces and is secured against escaping laterally from the wire guide, wherein the bracket includes an occlusal hook with a widened head, and wherein wire guide surfaces include a lingual pad surface, a vestibular surface of the hook, and an apical surface of the head.
