Comparative analysis of passive play and torque expression in self-ligating and traditional lingual brackets

ConclusionsSTb and ALIAS brackets generated the lowest passive play; STb and In-Ovation  L brackets showed the lowest angle of play at the greatest torque expression. These measurements allow to understand the accuracy of lingual systems and at the same time the amount of overcorrections to be applied in the setup in order to obtain high quality orthodontic treatments.
