Dentsply introduces Midwest Stylus ATC handpiece

The Midwest Stylus ATC introduces the dental world to Speed-Sensing Intelligence (SSI) and Superior Turbine Suspension (STS), groundbreaking technologies that solve two longstanding challenges facing dentists: load-based variations in speed that can cause stalling and require time-consuming feathering, and bur deflection and chattering that occur at high speeds and can affect accuracy and precision.

It’s the speed

The Midwest Stylus ATC’s Speed Sensing Intelligence automatically optimizes the delivery of power, no matter the load, to provide smooth, consistent cutting 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 Suspension allows the handpiece to operate at speeds of 330,000 rpm under load with no noticeable bur deflection or chattering. 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 absolute maximum in cutting efficiency. No other handpiece on the market today allows dentists to create this degree of precision.

In fact, this smooth, precise control is especially beneficial for margin refinement and fine restorative procedures.

“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 Professional.

“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 Intelligence and Superior Turbine Suspension, 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 surfaces with standard- and short-shank bur compatibility.
• All-day ergonomic comfort; significantly lighter than electric handpieces.
• Brilliant fiber-optic light for superior illumination.
• Low pitch and tone for a more relaxed patient and dentist.

The Midwest Stylus ATC is the most powerful, yet precise, high-speed, air-driven handpiece available in the world today.
