T1 Premium-Class



PREMIUM – T1 Turbines. 
Perfection that fits into your hands.

The instruments in the T1 Premium class provide maximum accuracy and perfect work results. Innovative, first-class technology, extra light titanium 
sleeve and ergonomic design ensure that T1 CONTROL, T1 Boost and T1 mini satisfy every requirement. The Premium Class Turbines lie perfectly 
balanced in your hand.

T1 mini's small head gives you a perfect view, while T1 CONTROL's patented speed control allows a consistent and noise-free work and T1 Boost
offers maximized performance – extremely quiet.


  • Ergonomic lightweight titanium sleeves
  • Significantly more power with smaller head size
  • DLC coated ceramic ball bearings
  • Due to the 4-nozzle- spray the turbines are the most quiet within their class
  • Protective-Head-System (PHS ) with dual anti-retraction stop




The T1 Premium class will win you over

Work becomes fun: Top quality for first-class treatment.

T1 CONTROL – The power lies in the consistency

The power of the T1 CONTROL lies in its consistent torque.

Less is more. The patented CONTROL function ensures one-of-a-kind torque and continuous powerful preparation. With constant high torque at a speed of 250,00 rpm, Sirona shows that the power of a turbine in no way depends on the pure rotation speed. You can drill quickly – without stopping to pick up speed again – that way you save valuable work time.

The consistent speed during preparations and thus to prevent thermal damage to the tooth. At the same time, this consistency also reduces significantly the noise level.

The patented CONTROL function

Controlled speed

The highspeed handpiece independently controls the speed, so you no longer need to stop to pick up speed again.

Mode of operation

While rotating, the O-ring  expands due to centrifugal force. This results in less driving air reaching the rotor, so that the rotational speed is kept at approximately 250.000 min-1.

As soon as the bur touches the tooth, the O-ring  becomes smaller due to the reduction in centrifugal force, and the driving air to the rotor increases. The optimum working speed of approx. 250.000 min-1 is thus maintained.

T1 Boost - more powerful, smaller, quieter

As a dentist you know good results highly depend on the performance of your instruments: More power in your hand means less effort for you.

The 23 watts of the Boost variant allows for working almost without interruption with even more torque, combined with a significantly lower noise and reduced head size - More power, more torque, more efficiency.

T1 mini – Do more with mini heads.

With the extra small mini head options you get optimum access to the molar region and a perfect view of the preparation site. T1 mini owns an impressive head size (height: 12.7 mm, diameter: 10.2 mm) to torque ratio.
