Abstract
The play between the preadjusted brackets and undersized archwires accommodate the anatomic variations of teeth, with some loss of torque control. Full size archwires should be used with customized brackets to fully control the torque. However, this does not guarantee the treatment result similar to the ideal model setup that was used to fabricate customized brackets. Nevertheless, customized brackets have their value in that it may reduce the round-trip tooth movements by reducing bracket repositioning or wire bending. Customized brackets will prevail in the future along with the progress of 3D printing technology.
