The unique double impeller heightens torque by up to 50 percent, and improves torque stability – including under high levels of strain. The device’s steady removal power promotes silky smooth preparation, with substantially greater precision.
Even the Ultramini series, with their only nine millimeter in diameter heads, deliver a unique preparation power ranging up to 20 watts.
The air from the drive nozzles drives the primary impeller. The exhaust air is channeled via ribs and drives the second impeller. The result: extremely high and steady torque, even under a load.

This unique design produces 18W of power for the Ultra M, 20W for Ultra E, 22W for Standard, and 25W* for the High Torque series. Cuts smoothly through ceramic and metal prostheses with ease.

* Power measurements are based on ISO 14457:2017.
TwinPower Turbine 4H: Measured at a pressure of 0.29MPa at the handpiece itself. 

Thanks to the unique and patented quick-stop system, tooth preparation with TwinPower becomes more precise, and your patients experience greater comfort during treatment. This in turn also reduces the risk of injury.
The unique TwinPower Plus quick-stop system enables the turbine to stop in only two seconds without any jolts or hesitation. This in turn promotes tooth preparation accuracy and efficiency.

The zero suck-back effect promotes optimal hygiene:

1. The drive air flows into an anti-suck back diffuser (ASBD) that is located inside the impeller capsule. The ABSD builds up air pressure thanks to the centrifugal force engendered by rotation.
2. The rotation and centrifugal force enable the air to flow into the ASBD, where it remains compressed – even after the drive air ceases to flow.
3. The compressed air in the ASBD is expelled on the lower side of the head.
4. The exhaust air is also expelled by the impeller on the lower side of the head, via the ASBD.
5. The air pressure that builds up in the ASBD prevents pressure loss in the head, thus completely eliminating the suck-back effect.

The most powerful TwinPower Turbine yet with up to 47 watts of power. The new TwinPower Turbine G-Series features a redesigned true rotor and narrow torque ripple design to deliver up to 47W of power and smooth, strong cutting. Its unrivaled power makes it one of the most powerful air-driven handpieces available today. Even when cutting through the hardest materials, like Zirconia**. All while retaining Morita’s patented Zero Drawback Technology, Quick-Stop, and the ease of visibility of the TwinPower Turbine line. Super High-Torque at 47W of power (G-Series only) Easy Access and Visibility Built-in Infection Control with patented Zero Drawback Technology Safe, rapid braking technology.

The small instrument heads of the Ultra series with a diameter of 9 mm provide not only a clear and direct view of your work area but also sufficient room for movement when treating molars. The head angle of 15° adds to treatment comfort. For this reason these turbines are particularly suitable for dental work on children and older patients as both these age-groups have difficulty opening their mouths very wide.

The new coupling system in the TwinPower turbines is also compatible with devices made by other manufacturers.

Thanks to their compact and lightweight design, our TwinPower turbines deliver outstanding operating comfort, even when used intensively. Their extremely light weight (only 50 grams) reduces strain on the hand and finger muscles and tendons.

The latest advances in fluid dynamics eliminate the highly uncomfortable noise generated by high speed turbines that operate in the 6 to 7 kHz range. As a result, preparation work with the turbine is quieter and more agreeable for both the dental practice team as well as the patient.

Excess drive air is channeled sideways almost imperceptibly, in order to spare the patient the normally uncomfortable sensation engendered by the stream of cold air from the turbine handpiece. Neither patients nor the practice team experience any unpleasant sensation of cold at the preparation point.

The fiberglass light guide guarantees a constant brightness (25,000 lux) and significantly improved stability even after countless sterilization cycles in the autoclave (135° C).

The easy to handle and highly precise metal clamping system ensures that preparation instruments remain in place. At the same time, the push-button clamping system has been designed and endurance tested for a long service life.
