I am thinking about upgrading to an electric handpiece for more power, but I am concerned about the cost and added weight – are there any air-driven high-speed handpieces that perform like an electric handpiece?

With most air-driven handpieces, the heavier the load, the higher the likelihood of stalling and bur slippage. DENTSPLY Professional has designed the MIDWEST Stylus ATC with patented Speed-Sensing Intelligence to virtually eliminate stalling under heavy loads. The handpiece senses the amount of torque delivered and automatically adjusts torque to maintain peak power. It also limits the speed when the bur is not under load to minimize wear on the handpiece bearings. Midwest Stylus ATC does not weigh as much as an electric handpiece, thereby reducing hand strain.
