Background: One of the most difficult procedures in orthodontics is space closure, which necessitates a thorough understanding of biomechanics to prevent unfavourable side effects.Despite the wide range of appliance designs, space closure can be accomplished using friction or frictionless mechanics; each method has pros and cons.In this study, we aim to use the self- ligating brackets which is a cost - effective approach to evaluate the anchorage loss and velocity of canine retraction compared to conventional bracket.
