The present disclosure is directed, at least in part, to a self ligating orthodontic bracket system that includes a rotatable member for securing an archwire within a slot of a bracket. Embodiments of the orthodontic bracket system disclosed herein include a bracket body containing the archwire slot as well as tie wings for attaching various orthodontic devices (e.g., elastomeric bands) to the bracket. The rotatable member is rotatable in a first direction (e.g., counter clockwise) relative to a body of the bracket for securing or locking the archwire within the slot, and for rotating in an opposite direction (e.g., a clockwise direction) relative to the bracket body for unsecuring or unlocking the archwire so that it is substantially unrestrained from exiting the slot. Other embodiments include an orthodontic appliance and method of producing and using the same, and preferably employed in a lingual orthodontic system, that includes friction reducing features between an interior of an archwire slot portion of the appliance and an archwire placed within the archwire slot.
