Feedback function The iPiezo engine powers the tip according to the pressure applied by the operator and thus behaves like a hand instrument, ensuring stable scaling performance. Autotuning-Funktion Auto tuning automatically adjusts the oscillation frequency to deliver the desired power to the tip. The tip adheres precisely to the tooth surface, enabling the clinician to properly sense the surface condition. Independent unit and chamber The detachable chamber and handpiece make it possible to easily switch between supragingival and subgingival applications and make the unit extremely user and maintenance friendly. User-friendly handpiece and nozzle The slim handpiece provides excellent accessibility and manoeuvrability inside the oral cavity. The long, compact nozzle provides easier access to molars, reducing discomfort to both clinicians and patients by eliminating unnecessary lip and cheek stretching while maintaining a wide operative field. Multi-Foot Control NSK extensively researched foot movement and sensory feeling when developing the Multi-Foot Control to enable clinicians to operate the unit hands-free to facilitate uninterupted procedures. Just using the foot the user can switch ultrasound or powder modes on or off and change power settings. Combined with a hanger, this offers complete hands-free operations.
