Subject: Temporary Anchorage Devices in Orthodontics
Date: September 26, 2011
Important NoteThis Clinical Policy Bulletin expresses our determination of whether certain services or supplies are medically necessary. We reached these conclusions based on a review of currently available clinical information including:
PolicyAetna considers a temporary anchorage device (TAD) to be a device that is temporarily fixed to bone for the purpose of enhancing orthodontic anchorage. The procedure includes the device removal.
BackgroundA temporary anchorage device (TAD) is a biocompatible device that is fixed to bone to enhance orthodontic anchorage and/or overcome anchorage limitations. It is used during procedures to move teeth by either supporting the teeth of the reactive unit or by preventing the need for the reactive unit altogether. The TAD is removed after treatment and the removal is considered part of the overall TAD procedure. TADs may be located transosteally, subperiosteally or endosteally and may be fixed to bone either mechanically (cortically stabilized) or biochemically (osseointegrated).
Codes1D7292 -- Surgical placement: temporary anchorage device [screw retained plate] requiring surgical flap. Insertion of a temporary skeletal anchorage device that is attached to the bone by screws and requires a surgical flap. Includes device removal.
