[A comparative assessment of mechanical property between lingual and labial archwires using three-dimension finite element method].

Purpose: The purpose of this study was to investigate the mechanical property of lingual and labial archwires by using finite element method.

Methods: A three-dimensional finite element model including three maxillary left incisors of the 0.022-inch Dentaurum Discovery labial and Ormco 7th Generation lingual brackets was constructed and threaded with corresponding labial and lingual archwires.
