A new, high-speed, air-driven hand- piece is promising an entirely new cut- ting experience for dentists, one that is so smooth, powerful and efficient, it doesn’t feel like work anymore. The Dentsply Midwest® Stylus™ ATC is the world’s first air-driven hand- piece to automatically adjust speed in response to load, offering superior performance and precision. The Midwest Stylus ATC introduc- es the dental world to Speed-Sensing Intelligence (SSI) and Superior Tur- bine Suspension (STS), groundbreak- ing technologies that solve two long- standing challenges facing dentists: load-based variations in speed that can cause stalling and require time- consuming feathering, and bur deflec- tion and chattering that occur at high speeds and can affect accuracy and precision. It’s the speed The Midwest Stylus ATC’s Speed Sens- ing Intelligence automatically optimiz- es the delivery of power, no matter the load, to provide smooth, consistent cut- ting speeds for unmatched efficiency and the fastest removal of material. A sensor in the coupler picks up the frequency of vibrations caused by the speed of the rotating bur. When the bur encounters a higher load that would normally cause a decrease in speed, a signal from an advanced “electronic brain” in the control source increases air pressure and thereby the rotation of the turbine, thus increasing speed. The opposite occurs when the bur encounters a lighter load. In other words, in a split second, the handpiece knows when to deliver more power or when to reduce power. It’s the suspension The ATC’s Superior Turbine Suspen- sion allows the handpiece to operate at speeds of 330,000 rpm under load with no noticeable bur deflection or chatter- ing. This provides outstanding control, every time. The STS also creates a greater, more consistent transference of power from the handpiece to the bur for the abso- lute maximum in cutting efficiency. No other handpiece on the market today allows dentists to create this degree of precision. In fact, this smooth, precise con- trol is especially beneficial for margin refinement and fine restorative pro- cedures. “This is the greatest breakthrough in high-speed, air-driven handpieces since their introduction by Midwest in the 1950s,” said Len Litkowski, DDS, and director of professional relations and clinical research for Dentsply Pro- fessional. “Bringing electronic control to the dental handpiece to provide a constant speed, even under load, will make the dentist’s experience more efficient, effective and stress-free,” he said. Controlled power in a small package In addition to Speed-Sensing Intel- ligence and Superior Turbine Suspen- sion, the Midwest Stylus ATC offers these advantages: • Exceptional visibility, access and maneuverability with mini or mid- sized head. • Outstanding swivel for freedom of movement. • Enhanced access to posterior sur- faces with standard- and short-shank bur compatibility.
