Abstract: An orthodontic bracket axis indicator for use with an orthodontic bracket including a long slot intersecting with an archwire slot having a base surface and first and second opposed slot surfaces extending from the base surface includes an insert having first and second elongate cross members having first and second top surfaces, respectively, and arranged generally perpendicular to each other such that, when viewed from above, the insert has a generally cruciform shape. First and second grooves extend along the first and second top surfaces of the first and second cross members, respectively, and are each configured to receive an orthodontic tool. The first cross member is configured to be received by the archwire slot and the second cross member is configured to be received by the long slot in order to provide an interference fit between the insert and the orthodontic bracket.

Abstract: An orthodontic bracket for coupling an archwire with a tooth includes a bracket body and a rotatable member. The rotatable member is rotatable between an opened position and a closed position. A retention member secures the rotatable member to the body and a locking mechanism that provides at least one positive stop in the rotation of the rotatable member and that produces a discernible indication when the rotatable member is in at least the closed position. In one closed position, the rotatable member actively ligates the archwire and in the other closed position, the rotatable member passively ligates the archwire. The locking mechanism is separate from the retention member and includes at least one pin that slidably contacts the rotatable member. The pin has a longitudinal axis and the retention member has a longitudinal axis. The axis of the pin is oriented perpendicular to the axis of the retention member.
