The Device Description: Varios 970 consists of the Varios 970 Control Unit, two independent 400 mL irrigation bottles, handpiece, and a wide range of tip inserts. The tip inserts, when attached at the distal end of the handpiece transducer, resonate at ultrasonic frequencies of 28 -32 kHz. The 400 mL bottles each can carry different solutions with independent pumps. The Varios 970 LUX features twin LED lights that last longer, are more durable, and generate less heat than halogen bulbs. Statement of This device, Varios 970, an electronic ultrasonic scaler, is intended for use with an Intended Use: appropriate tip for following use: Scaling, Perio, Implant Maintenance, Endodontic, Retrograde Endo, Restorative (for ----Minimal Intervention/ Finishing/Trimming/ Polishing/Caries of Dentin), Prosthetics (Condensation / Loosening / Plugging) Both the Varios 970 and the predicate Varios75 utilize the iPiezo engine to generate ultrasonic frequencies of 28 -32 kHz. Both have the same operating modes, irrigation Characteristics: modes, and operating time. During the mode of operation, a sinusoidal electrical. signal, at ultrasonic frequency (f > 20kHz), is generated and delivered to the 'piezoelectric ceramic' located inside the handpiece transducer. The electrical signal is converted into mechanical vibrations and propagated to the distal end of the handpiece. Summary of The Varios 970 has been tested in accordance with applicable standards for medical device Test Data: electrical safety, electromagnetic compatibility, and the particular requirements for sterilization. Conclusion: Nakanishi, Inc. considers the Varios 970 Ultrasonic Scaler to be substantially equivalent to the predicate device (Varios 75) listed above. This conclusion is based on the similarities in primary intended use, principles of operation, design rationale, and performance.
