Abstract
An orthodontic bracket having an external rotatable closure member with a plurality of closed positions. The rotatable member includes a body portion that defines an opening for receiving a bracket body. A ligating portion extends from the body portion and has at least one retention arm that forms a lumen in a closed position. An opening defined by the rotatable member receives the cylindrical bracket body. The rotatable member encircles at least a portion of the bracket body. The orthodontic bracket may include a locking mechanism that couples the rotatable member to the bracket body and that provides at least one positive stop in the rotation of the rotatable member. The locking mechanism may include a spring pin and a retention aperture having at least one nonplanar surface. The spring pin slidably cooperates with at least a portion of the nonplanar surface during rotation of the rotatable member.
