## Intended Use

The ELEC-LED is intended for use in dentistry for restoration, prophylaxis and endodontic procedures. It provides control for motorized dental handpieces by converting pneumatic output from a dental treatment center.

## Device Story

ELEC-LED is a micro motor controller and display panel used in dental clinics. It receives AC 24V input and converts pneumatic output from a dental treatment center to power and control motorized dental handpieces. The device features three operating modes: Hand control (HD), Press pedal (PP), and Electric pedal (EP). Operators use the display panel to set motor speed, operating mode, light, and spinning direction. The system enables precise control of handpiece rotation (clockwise/counterclockwise) and torque for dental procedures. By providing a controlled interface for electric motors, it assists clinicians in performing restorative, prophylactic, and endodontic tasks efficiently.

## Clinical Evidence

Bench testing only. Testing included ISO 3964 (coupling dimensions), ISO 7494-1 (dental units), ISO 14457 (handpieces/motors), IEC 60601-1/60601-1-2 (electrical safety/EMC), IEC 80601-2-60 (dental equipment safety), IEC 62366 (usability), and sterilization validation (ANSI AAMI ST79, ISO 17665). Biocompatibility testing (cytotoxicity, sensitization, oral mucosa irritation) was performed per ISO 10993-1.

## Technological Characteristics

Micro motor controller with display panel. Brushless motor with internal coolant air. Power supply: AC 24V. Speed: 1,000-40,000 rpm. Max torque: 3Ncm. Connectivity: Pneumatic interface to dental treatment center. Compliance: ISO 3964 (shanks). Sterilization: Validated per ISO 17665. Software: Moderate level of concern.

## Regulatory Identification

A dental handpiece and accessories is an AC-powered, water-powered, air-powered, or belt-driven, hand-held device that may include a foot controller for regulation of speed and direction of rotation or a contra-angle attachment for difficult to reach areas intended to prepare dental cavities for restorations, such as fillings, and for cleaning teeth.

Dear Priscilla Chung:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal

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

statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see

https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

#### Substantial Equivalence Discussion: 6.

The subject device is substantially equivalent to Optima MX INT SI0915/923(K042759). The subject device has the same indications for use and the technological characteristics as the predicate device. It also has the equivalent specifications as the predicate device in almost all parameters. The major difference is that the subject device offers a model without water and air spray hoses, and also a model without LED. However, these differences do not raise a question in substantial equivalence discussion since the user can use water and air spray hoses that are usually provided on a dental chair, and lighting system in the dental office. Since these are optional features, we believe these differences do not raise a concern for substantial equivalence. Based on the comparison and the performance test data, we conclude that the subject device is substantially equivalent to the predicate device.

## 7. Performance Tests (Non-clinical)

Non-clinical bench tests were performed as followings:

- ISO 3964:2016 Dental Handpieces Coupling dimensions
- ISO 7494-1:2011 Dentistry Dental units -Part 1: General requirements and test methods
- ISO 14457:2017 Dentistry Handpieces and motors
- IEC 60601-1, IEC 62366-1, IEC 60601-1-2: Electrical safety and EMC

- IEC80601-2-60:2012: Particular Requirements For The Basic Safety And Essential Performance Of Dental Equipment

- IEC 62366: Application of usability engineering to medical devices
- ANSI AAMI ST79:2017, ISO 17665-1, and ISO TS 17665-2: Sterilization validation

Software documentation for software of moderate level of concern per the FDA Guidance Document for Software Contained in Medical Devices was provided . The test results support that the subject device is substantially equivalent to the predicate device.

Cleaning and Sterilization validation for the motor cable was provided per the FDA Guidance Document for Reprocessing of Medical Device.

Biocompatibility testing (cytotoxicity, sensitization, and oral mucosa irritation) for the direct and indirect patient contacting components was provided per the FDA Guidance Document for the Use of ISO 10993-1.

#### 8. Conclusions:

Based on the information provided in this premarket notification, MICRO-NX Co., Ltd. concludes that the ELEC-LED is substantially equivalent to the predicate device as described herein in.
