A comparative experimental investigation of torque capabilities induced by conventional and active, passive self-ligating brackets.

Introduction: A proper selected bracket-archwire combination displays a determining factor in the efficacy of torque applied to a tooth at the final stages of an orthodontic treatment. The objective of the current study was to assess the torque capabilities of various bracket systems combined with diverse archwire materials and cross-sections.

Methods: The study comprised of four different 0.
