#### Intended Use/Indications for use

The Multipiezo Pro and Multipiezo are piezoelectric ultrasonic dental scalers intended for use, with the appropriate associated tip inserts, in the following dental applications:

- . Scaling: All general procedures for removal of supragingival and interdental calculus/ plaque deposits;
- . Periodontology: Periodontal therapy and debridement for all types of periodontal diseases, including periodontal pocket irrigation and cleaning:
- Endodontics: All treatments for root canal reaming, irrigation, filling, gutta-percha condensation and ● retrograde preparation;
- Restorative and Prosthetics: All general restorative procedures including cavity preparation, removal of . prostheses, amalgam condensation, finishing of crown preparations, inlay/onlay condensation, implants/restorations cleaning.

#### Device Description and Technological Characteristics:

The Multipiezo Pro and Multipiezo devices are dental piezoelectic ultrasonic devices that use ultrasonic energy to generate mechanical micro-vibration of the inserts to perform the dental procedures defined in their intended use.

The Multipiezo Pro consists of a base control unit (console) with two integrated peristaltic pumps which deliver irrigation liquid, contained in two independent detachable 500 ml bottles, to two sterilizable ultrasonic handpieces with connecting cords. The selection of the irrigation fluid occurs automatically when the operator removes the handpiece from the support associated with the tank containing the liquid that the dentist wants to use for the treatment. Only one handpiece can be used at a time.

The Multipiezo device consists of a base control unit with a single integrated peristaltic pump which delivers the irrigation liquid contained in one detachable tank to one single ultrasonic handpiece with connecting cord.

The consoles of both devices are connected to mains power by an electrical cord, and include connectors for the hand piece/s and for the footswitch. The consoles incorporate peristaltic pump/s which provide/s the irrigation fluid contained in the tank/s to the operation site.

The handpiece contains a piezoelectric ultrasonic transducer which is connected to the ultrasonic generator (inside the console) by a cable at one end and to which tip inserts are attached at the other end.

The ultrasonic generator, identical in both devices, is microprocessor-based and uses electronics to generate and control the appropriate drive signal (power and frequency) for the transducer in the handpiece. A touch screen on the console of both devices allows the setting of treatment parameters, as follows:

- Four type of functions (Endo, Perio/Scaler, Restorative, Soft Mode) that can be adjusted through 6 power levels
- . Seven different levels of irrigation (from 0 to 6)
- . Insert tip illumination (on, off or auto)
- Flush function. .

#### Non clinical testing

The Multipiezo Pro and Multipiezo devices comply with the electrical safety and electromagnetic compatibility requirements established by the standards IEC 60601-1 and IEC 60601-1-2.

Bench testing of the subject devices includes:

- Testing to confirm compliance with the safety requirements of standard IEC 60601-1 .
- Testing to confirm compliance with EMC requirements of standard IEC 60601-1-2 .

#### Substantial Equivalence

The substantial equivalence of the subject devices is based on the following predicate devices:

- . EMS Piezon Master 600, manufactured by Electro Medical System SA, 510(k) reference K022328, cleared on 13 August 2002.
- Compact Piezo P2K, manufactured by Mectron Spa, 510(k) reference K102218, cleared on 24 January . 2011.

The technological characteristics and operating parameters of the Multipiezo are identical or very similar to those of the predicate devices. With respect to the functional aspects, the Multipiezo Pro and Multipiezo use the same fundamental technology as the two predicate devices.

Both the subject devices and the predicate devices use same piezoelectric technology to generate mechanical micro-vibration to the inserts to perform the dental ultrasound treatments according to their intended use.

Both the subject devices and the two predicate devices have the ultrasonic transducers housed in the respective handpieces. The transducers of the Multipiezo and of the predicate devices are formed by piezoceramic disks which convert the input electrical power to mechanical vibration of the insert.

Any differences between the subject device and one or other of the predicate devices is not significant with regard to device safety or effectiveness

#### Conclusion

The Multipiezo pro and Multipiezo and the predicate devices share the same general intended use and technology.

The differences existing between the subject devices and the predicate devices relating to technical specifications, performance and intended use are minor and do not affect safety and effectiveness.

The data presented in this submission demonstrate the similarities in the intended use/indications of use and technology existing between the Multipiezo Pro and Multipiezo devices and the referenced predicate devices. and thus supports a finding of substantial equivalence between the subject device and the predicate devices which are already in commercial distribution in the United States.
