Intended Use

The MEGA ISQ is indicated for use in measuring the stability of implants in the oral cavity and maxillofacial region.

Device Story

The MEGA ISQ is a portable, handheld dental instrument used to assess implant stability via Resonance Frequency Analysis (RFA). The system utilizes a Smartpeg (aluminum rod with a magnet) screwed onto a dental implant. A measurement probe on the handheld instrument emits a magnetic pulse to excite the Smartpeg, causing it to vibrate at its resonance frequency. The instrument detects the response signal, calculates the resonance frequency, and displays the result as an Implant Stability Quotient (ISQ) value (0-100). The ISQ value, proportional to implant stiffness, assists clinicians in evaluating stability. The device is used in clinical settings; it does not store data. The MEGA ISQ is a simplified version of the predicate, featuring an LED display and a docking station for USB connectivity, while removing internal RAM and real-time clock functions.

Clinical Evidence

No clinical data was required to support the changes to the Osstell ISQ. Substantial equivalence was established through bench testing, including comparative performance testing against the predicate, material biocompatibility, and conformance to EN IEC 60601-1-2.

Technological Characteristics

Portable handheld instrument; Resonance Frequency Analysis (RFA) principle; LED display (58mm x 37mm); ABS plastic and Dryflex TPE materials; rechargeable power source; USB interface via docking station; sterilization per ANSI/AAMI/ST79:2010/A2:2011; no internal data storage.

Indications for Use

Indicated for measuring dental implant stability in the oral cavity and maxillofacial region.

Regulatory Classification

Identification

#### Device Description:

The MEGA ISQ is an new generation of the Osstell ISQ, (K082523) the system is designed to measure dental implant stability in the oral cavity and maxillofacial region. Similar to K082523, the MEGA ISQ is a portable, handheld instrument that involves the use of the noninvasive technique, Resonance Frequency Analysis. The system involves the use of a Smartpeg (aluminum rod) attached to the dental implant by means of a screw. The Smartpeg is excited by a magnetic pulse from the measurement probe on the handheld instrument. The resonance frequency, which is the measure of implant stability, is calculated from the response signal. Results are displayed as the Implant Stability Quotient (ISQ). The ISQ is a measurement of the stability of the implant and is derived from the resonance frequency value obtained from the Smartpeg.

{1}------------------------------------------------

#### Indication for Use:

The MEGA ISO is indicated for use in measuring the stability of implants in the oral cavity and maxillofacial region.

### Summary of Technological Characteristics:

The modifications to the Osstell ISQ since its previous clearance in K082523 include the following changes:

- Replacing the existing display with a LED display .
- . Removing the RAM memory
- Removing the real time clock .
- Move the USB interface to a dock station .
- A new material is added to the instrument and docking station to improve grip ability .

These minor differences do not affect the safety or performance of the device and do not change the intended use of the MEGA ISQ. These changes were implemented to address the needs of the customer for a basic device which offers the same Resonance Frequency Analysis technology, but does not offer the capability of data storage. The relocation of the USB interface allows a reduce size, as well as allowing for a slightly larger display.

#### Summary of Nonclinical Testing:

Based on the Risk Analysis, the verification and validation tests that were performed and the acceptance criteria applied included:

- . Conformance to EN IEC 60601-1-2
- . Comparative performance testing to predicate
- Material biocompatibility .
- . Updated steam sterilization parameters in accordance with

```
ANSI/AAMI/ST79:2010/A2:2011
```
The proposed device passed all applicable test per IEC 60601-1-2, comparative testing of the new LED display, performance of the USB interface, and performance and biocompatibility of the new material demonstrated equivalent performance to the declared predicate.

#### Clinical Studies:

Clinical data was not required to support the changes to the Osstell ISQ.

### Conclusion:

The change to display, RAM memory, Clock ,USB interface, and additional device material of the MEGA ISQ do not change the intended use nor do they affect the safety and effectiveness as compared to the Osstell ISQ previously cleared in K082523. Therefore the MEGA ISQ can be found substantially equivalent to the Osstell ISQ cleared in K082523.
