[Advances in studies on distal molar movement with temporary anchorage devices].

Crowding and protrusion of the dentition are often the chief complaint of orthodontic patients. For patients with severe crowding or protrusion, orthodontist often improve their profile with premolar extraction treatment. However, for patients with mild crowding and protrusion, orthodontist usually achieve treatment objective using distal molar movement with temporary anchorage devices (TAD). The present article reviewed the advances in the use of TAD in total arch distalization, including therapeutic effect measured in three-dimensions, factors that affected distal movement and the stability of curative effect.
