Device Story

Piezosurgery Touch and White are table-top piezoelectric ultrasonic devices; console contains irrigation system, power supply, ultrasonic generator, control keyboard. Handpiece connects to console via cord; foot-pedal controls operation. Device uses piezoelectric transducer in handpiece to convert electrical energy into mechanical micro-vibrations of attached insert tips. Generator electronics automatically locate resonant frequency of transducer/tip combination (24-36 kHz). Used by dental professionals in clinical settings for oral surgery, periodontology, endodontics, and restorative procedures. Clinician selects specific tip morphology for procedure; device output (vibration) enables precise bone cutting or cleaning. Benefits include controlled, minimally invasive tissue interaction compared to traditional rotary instruments. This submission adds new insert tip designs to existing cleared systems.

Clinical Evidence

Bench testing only. Comparative performance testing evaluated tuning frequency and vibration amplitude of new inserts against predicate inserts, confirming operation within the 24-36 kHz range. Reprocessing validation performed on worst-case reprocessed tips. Biocompatibility testing (cytotoxicity growth inhibition in L929 mouse fibroblasts) conducted per ISO 10993-5:2009, showing no cytotoxic effects.

Technological Characteristics

#### DEVICE DESCRIPTION 4.

The Piezosurgery Touch and Piezosurgery White use ultrasonic energy to generate mechanical microvibrations of the available tip inserts to perform the dental procedures defined in its intended use.

They consist of a table-top unit (console) containing the irrigation delivery system, the internal electric power supply, the ultrasonic generator, and the control keyboard. They also includes the piezoelectric ultrasonic handpiece and foot-pedal, both connected directly to the console by means cords, and a variety of insert tips designed with different morphologies/shapes to be used for different dental procedures, according to device's intended use.

The table-top units use piezoelectric ultrasonic technology to generate mechanical micro-vibrations of the insert tip attached to the handpiece. A piezoelectric transducer, located inside the handpiece, and driven by the ultrasonic generator electronics, induces vibrations at ultrasonic frequencies in the insert tip.

The ultrasonic generator electronics searches and locates the resonant frequency of the transducer/insert tip combination, which varies according to the geometry/morphology of the insert tip in use. The functional ultrasonic frequency of the device is between approximately 24 and 36 kHz.

Each of the insert tips is available separately.

The purpose of this 510(k) is to add additional insert tip designs to the PIEZOSURGERY TOUCH and PIEZOSURGERY WHITE to extend the number of insert tips already cleared for sale in the US under K122322 and K151248.

#### 7. SUBSTANTIAL EQUIVALENCE

The new insert tips are substantially equivalent to insert tips already FDA-cleared for use with the Predicate Devices or the Reference Device, as follows:

| Subject Insert Tip | Predicate Insert Tip | Predicate/Reference Device 510(k) # |
|--------------------|----------------------|-------------------------------------|
| SLC | OP3 | K043408 |
| SLO-H | OT1 | K043408 |
| SLS | EL1 | K043408 |
| SLE-1 | EL2 | K043408 |
| SLE-2 | EL3 | K043408 |
| PL1 | OT5 | K043408 |
| PL2 | OT9 | K043408 |
| PL3 | OT11 | K151248 |

Finite Element Analysis (FEA) was utilized in the design of the new insert tips to ensure that the resonant ultrasonic frequency of the inserts was within the functional ultrasonic frequency range of the Piezosurgery Touch and Piezosurgery White.

The new insert tips share the same intended uses as the identified predicate insert tips, have very similar operative part shapes, and functional testing has demonstrated compliance with specifications, thus no new issues of safety and effectiveness are raised.

#### NON-CLINICAL TESTING 8.

The following non-clinical performance tests were completed.

# Comparative performance bench testing:

This test compares the performances of the subject inserts (SLC, SLO-H, SLS, SLE1 and SLE2) to their predicate inserts (OP3, OT1, EL2, EL2 and EL3) in terms of tuning frequency and vibration amplitude in order to establish their substantial equivalence, concluding that:

- The tuning frequency of the new inserts and of their predicate inserts is between 24 and 36 kHz, which is the range of the device functional ultrasonic frequency.
- The vibration amplitude of the new inserts and of their predicate inserts have comparable values.

## Reprocessing:

Separate cleaning and sterilization test have been carried out on a typical worst case reprocessed insert tip in order to successfully validate the reprocessing instructions provided with the reusable insert tips.

## Biocompatibility:

A cytotoxicity growth inhibition test in 1929 mouse fibroblasts, in accordance with ISO 10993-5:2009, was also carried out to demonstrate that a typical worst case reprocessed insert tip had "no cytotoxic effects in all extracts in the growth inhibition test with L929 mouse fibroblasts".

#### 9. CONCLUSION

Based on the information contained within this submission, the additional insert tips that are the subject of this submission, are substantially equivalent to the predicate device insert tips with of the Piezosurgery Touch and Piezosurgery White devices. It is concluded that the Piezosurgery Touch and Piezosurgery White devices that have been modified by the introduction of these new insert tips are substantially equivalent to the identified predicate devices cleared under K122322 and K151248, which are already in interstate commerce within the USA.
