The linear motion contra angle of the TorqTech series and the Ortho-Strips always are a perfectly matched instrument system that is outstandingly suited for carrying out interproximal reduction in orthodontics.  

The contra angle converts the rotary movement of the motor into a strong, linear motion. Given the 4:1 gear ratio and a wide range of number of throws, TorqTech is an optimal instrument to use for your treatments.
