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.
