Friction between Archwire of Different Sizes Cross Section Alloy and Brackets Ligated with Different Brands of Low Friction Elastic Ligatures- An Invitro Study

摘要

IntroductionFriction in orthodontic treatment does exist and is thought to reduce the efficiency of orthodontic appliances during sliding mechanics. During sliding mechanics, a friction force is produced at the bracket archwire-ligature unit which tends to counteract the applied force and in turn resists the desired movement.
