<br/><br/> Many advantages of the self- ligating (SL) brackets over the conventional (CL) ones have been claimed . The aim of this study was to evaluate and compare the effect of SmartClip SL brackets and conventional brackets on affecting the rate of passive extraction space closure by the canines and the axial inclination and tip of the teeth in extraction cases during the leveling and alignment stage
