Wide range of applications

Experience high-speed preparation

Effortless opening of cavities, easy cutting of crowns and bridges, removal of old fillings at lightning speed and finishing of preparation margins with ultimate precision.

Crown and cavity preparations

Preparation of cavities and crowns with minimal effort

The constantly high bur speed of 320,000 rpm allows efficient, controlled and precise performance of high-speed tasks.

You cannot only open cavities effortlessly, but also shape crown preparations safely and guarantee effective treatment.

Cut crowns and bridges

Cut crowns and bridges faster

Whether ceramic or metal, the removal and cutting of extremely robust, indirect restorations is a mighty challenge for the dentist and instrument alike.

The Primea Advanced Air allows you to set the recommended speed for the specific instruments and enjoy optimal, constant removal rate.

Remove fillings

Remove fillings safely and efficiently

From A for amalgam to C for composite to Z for zirconium dioxide: the Primea Advanced Air allows you to remove old fillings quickly and safely. The optimal ratio of minimum heat development to high removal rate is achieved at a speed of 160,000 rpm.

Controlled finishing

Controlled finishing

With the Primea Advanced Air you can perform this sensitive step with a constantly low bur speed of just 60,000 rpm.
This allows you to profile the preparation surface even more minimally invasively and finish the preparation margins with even more control than with a classic turbine handpiece.

Advanced Air technology

Advanced Air technology

With the Advanced Air technology, loss of speed is a thing of the past. A sensor in the head of the turbine measures the actual rotation speed of the bur on the tooth constantly. As soon as the speed threatens to slow, the control module adjusts the air supply immediately so as to ensure the constant removal of tooth structure.

Automatic power adjustment

Air control

• Speed setting
  You can set the required/recommended bur speed for the respective application on the display.
  
  
  • Speed check
    The speed actually measured in the bur head is checked against the set speed.
    
    
    • Speed regulation
      If the actual speed deviates from the set value, the air supply is accordingly adjusted immediately.

Tactile feedback

Additional function: operating mode

Whilst the set speed is always maintained constant under increasing pressure in »Power« mode, »Tactile« mode permits reduction of the speed. This makes it possible to perform sensitive steps with even more control and even more minimally invasively.
