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

DESCRIPTION OF THE DEVICE The OK handpiece is a reciprocating contra-angle handpiece that is used in connection with an air motor. The rotational force of the air motor is transmitted to the handpiece head through the shaft of the handpiece body, and the rotational force of the shaft is converted into vertical reciprocating {4}------------------------------------------------ motion in the head. The OK handpiece is a reprocessing medical device. Users must steam sterilize before each use, and clean thoroughly after use. The OK handpiece does not have water/air spray and light supply. Therefore, the air motor connection of the handpiece is designed to comply with the coupling size of TYPE 1 of ISO 3964. For the strip connecting to the OK handpiece, you must use Orthok-Strips and OK Proxofile of Jaintek Co., Ltd. #### INDICATION FOR USE 5.

Predicate device 1 has a water spray function, but subject device does not have a water spray function. However, since the predicate device 2 also does not have a water spray function, the presence or absence of the water jet function does not affect safety and effectiveness. Since the bur extraction force of the predicates devices is unknown, it is not possible to compare ### 510(K) SUMMARY {6}------------------------------------------------ them equivalence. But, since the extraction force of the subject device satisfies the requirements of ISO 14457, safety and effectiveness are not affected. The subject device, predicate device 1, and predicate device 2 have different RPM ranges. However, since the RPM range of the target device is within the RPM range of the preceding device, safety or effectiveness is not affected. An accurate comparison of the raw materials for human contact between the subject and predicate devices cannot be made due to lack of information. However, since the suitability of the raw material has been verified through biocompatibility evaluation, it does not cause any problems with safety or effectiveness. #### 7. SUMMARY OF NON-CLINICAL DATA Non-clinical tests were conducted to verify that the proposed device met all design specifications as was substantially equivalent (SE) to the predicate device. The test results demonstrated that the proposed device complies with the following standards: ### () Bench Test The subject device is complied with the following performance standards: - ISO 3964 Third edition 11-2016, Dentistry Coupling dimensions for handpiece connectors ● - ISO 14457 Second edition 2017-10, Dentistry - Handpieces and motors ### O Biocompatibility The subject device is manufactured from 304 stainless steel, which has been evaluated for the following biocompatibility in accordance with ISO 10993-1:2018. - ISO 10993-5:2009 (In vitro Cytotoxicity) - ISO 10993-10:2010 (Skin Sensitization) ● - ISO 10993-10:2010 (Oral mucosa irritation) ### O Sterilization The subject device is provided non-sterile. The end user must sterilize according to the recommended parameters (Pre-vacuum, 135 degrees/3 minutes sterilization, 30 minutes drying) using an autoclave before use. In this sterilization parameter, the subject device meets Sterility Assurance Level of 1E-6 and has been verified according to the standards below. - ISO 17665-1:2006, Sterilization of health care products - Moist heat - Part 1: Requirements for the development, validation, and routine control of a sterilization process for medical devices - ISO/TS 17665-2:2009, Sterilization of health care products - Moist heat - Part 2: Guidance on the application of ISO 17665-1 - ISO 11138-1:2017, Sterilization of health care products - Biological indicators - Part 1: General requirements - ISO 11737-1:2018, Sterilization of medical devices - Microbiological methods - Part 1: Determination of a population of microorganisms on products - ANSI/AAMI ST79:2017, Comprehensive guide to steam sterilization and sterility assurance in health care facilities {7}------------------------------------------------ ### 10. SUMMARY OF CLINICAL DATA Clinical Data was not required to demonstrate the substantial equivalence. ## 11. CONCLUSION OK Handpiece is manufactured from biocompatible raw materials. In addition, it has the similar indication for use, the same design characteristics, and similar performance as the predicate device. And the substantial equivalence of the subject device was confirmed through a non-clinical testing. Therefore, the OK Handpiece has been proven to be equivalent to a predicate device.
