title: Bilateral buccolingual forces produced by extraoral traction.
abstract: Extraoral appliances have been typically employed to deliver force systems to move teeth in directions parallel to the sagittal plane of the face. Their potential for concurrently producing transverse (buccal or lingual) movement has still not been fully explored. This study considers theoretical and experimental aspects of the magnitude and direction of such forces and related moments.
