Through voltage application piezo ceramic rings become stimulated – they

contract and expand. An axial movement is the result of it. It modifies motion to

the instrument (e.g. saw). The instrument becomes horizontal swinging.

The Piezo Principle

Why Piezo?

> The extremely short movements of the working instrument (tip) allowed a

precise and non-traumatic treatment of hard and soft tissue

> These offers micrometrical cuts for minimal invasive surgeries

> the cavitation effect of ultrasonic offers intra-operative-visibility

> High surgical control

> Precision and safety for user and patient

Difference to traditional technologies

Treatment with rotating instruments:

+ Fast

+ Huge assortment of rotating instruments

+ Useable in many application segments

Bone surgery / Implantology

Endodontology

Periodontology

Huge bone loss (diameter of rotating instrument)

Hard vibrations

Dangerous for soft tissue

Difference to traditional technologies

Treatment with surgical saws

+ Fast

+ Practicable method in bone surgery

+ Reciprocating, oscillating and sagittal

movement of saw blades

Huge bone loss (cutting width)

Hard vibrations

Limited application (only saw applications)

9

Difference to traditional technologies

Treatment with Piezo technology

+ Less traumatic

+ Less vibration

+ Not noisy

+ Less bone loss

+ Useable for many applications

+ Strong reduced risk of injury of soft tissue

Starting operation

> The filling function of the coolant hose prevents the piezo

instruments from swinging without load - protecting the

instruments.

> Once the device has been switched on, pressing both the

PLUS/MINUS buttons together activates coolant hose filling without

activating the piezo resonator.

> The filling process is stopped by pressing any button.

> If no button is pressed, the filling function stops after 15 seconds.

> The filling function can be started at any time by pressing both the

PLUS/MINUS buttons together.
