Abstract :
Achieving correct torque is one of the major goals of orthodontic treatment. Torque when expressed correctly, affects the esthetics as well as stability of teeth. Torque can be achieved either by bending the wire, use of torqueing auxiliaries or incorporating torque in the bracket itself. All these methods have their respective drawbacks leading to adverse effects. Hence, we have developed a new bracket system called Brackets for variable Torque and Rotation (BaTR) which allow us to customize the magnitude and direction of torque within each bracket. These brackets have four legs extended from the base of the bracket which need to be manipulated before bonding. Each bracket offers six options i.e labial torque in three magnitudes and palatal/lingual torque in three magnitudes. This is a very simple, precise and cost effective method, negating the use of conventional mechanics for torque application.
