DENTSPLY Midwest® Stylus™ ATC Handpiece
New handpiece introduces groundbreaking Speed-Sensing Intelligence (SSI) and Superior Turbine Suspension (STS) technologies.
Anew, high-speed air-driven handpiece is delivering an entirely new kind of cutting experience, one that dentists report is as smooth and powerful as it is efficient and easy to use. The DENTSPLY Midwest® Stylus™ ATC is the world's first air-driven high-speed handpiece to automatically adjust speed in response to load, offering superior performance and precision.
The handpiece 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.
Speed-Sensing Intelligence (SSI)
SSI optimizes the delivery of power no matter the load, delivering consistent cutting speeds for unmatched efficiency and 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. This creates the most powerful air-driven high-speed handpiece available, allowing for unmatched cutting efficiency and faster removal of material.
Superior Turbine Suspension (STS)
STS is an exclusive feature of the Midwest Stylus ATC, allowing the handpiece to operate at speeds of 330,000 rpm under load without noticeable bur deflection or chattering.
STS also creates a greater, more consistent transference of power from the handpiece to the bur for maximum in cutting efficiency. No other handpiece on the market today allows dentists to create this degree of precision at 330,000 rpm, according to internal research conducted by DENTSPLY Midwest. This smooth, precise control is especially beneficial for margin refinement and fine restorative procedures.
Controlled Power in a Compact Package
In addition to the proprietary SSI and STS technologies, the Midwest Stylus ATC offers other advantages:
-
Exceptional visibility, access, and maneuverability with the Mini- or Mid-Sized heads
- 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
Numerous Clinical Advantages
After a short learning curve, users are reporting many significant clinical and operational advantages and benefits with the Midwest Stylus ATC system. For example, the ATC quickly cuts through amalgam without stalling because it automatically adjusts the torque to keep cutting. Once the amalgam is removed, the operator can move directly to refining the margin without having to change the bur or handpiece.
Users are also reporting better efficiency in removing PFM crowns. They cut through the porcelain with a diamond, then, using a bur, cut through the metal substructure in one continuous easy motion-often using only one bur on the metal substructure. On tougher new metals, such as zirconia, the ATC still allows fast and easy cutting with a diamond in one continuous movement.
Once the crown is removed, the operator can move directly to fine tuning the preparation to make a pristine margin. ATC lowers the torque to give the operator the finesse to finish the margin under high magnification with extreme accuracy.
Even occlusal reductions are faster because the ATC does not bog down, and it removes more material faster than other typical handpieces. Another area where it shines is in opening up interproximal contacts. ATC cuts smoothly through the contact in one continuous motion with great precision and control.
Conclusion
The Midwest Stylus ATC represents a significant breakthrough in air-driven, high-speed handpieces since their introduction by Midwest in the 1950s. 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. Providing enhanced precision, control, and efficiency will make for a better dental experience for both the dentist and for the patient.
