    Abstract: An orthodontic appliance allowing the terminal ends of the archwire to be oriented and retained in a non-distal direction, as well as a method for using the disclosed appliance, is comprised of an appliance including at least a first and second archwire slot. The appliance is formed with a base and a body, wherein the body has two archwire slots passing therethrough. The archwire slots are arranged so that the archwire may be inserted into the first archwire slot in a distal direction and subsequently inserted into the second archwire slot in a non-distal direction (e.g., a substantially mesial, mesiolingual, mesiogingival, mesiogingivolingual distolingual, distogingival, or distogingivolingual direction). The archwire slots may be oriented as non-parallel to one another with respect to the vertical dimension and/or the transverse dimension. It is contemplated that at least the second archwire slot may be configured with a self-ligating archwire retaining mechanism.
