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. For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medicaldevices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn).

Indications for Use ELEC Master & ELEC Master Dual are intended for use in general dental applications such as: cutting a tooth for cavity preparation, crown preparation, crown finishing, inlay, filing, polishing, prophylaxis and endodontic treatment. ### 7. Substantial Equivalence Discussion: The subject device is substantially equivalent to A-dec NLZ electric motor system (K163131). 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 spray air pressure & spray water pressure. However this 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 in the dental office. Since these are optional features, we believe these differences do not raise a new question in safety and effectiveness. Based on the performance test data, we conclude that the subject device is substantially equivalent to the predicate device. | | Candidate Device | Predicate 1 | Comparison | |-------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------| | 510(k) Number | K202963 | K163131 | - | | Device Name | ELEC Master<br>ELEC Master Dual | A-dec NLZ electric motor<br>system | - | | Manufacturer | MGNEWTON Ltd. | NAKANISHI INC. | - | | Indications for Use | ELEC Master &<br>ELEC Master Dual<br>are intended for use in<br>general dental<br>applications such as:<br>cutting a tooth for<br>cavity preparation,<br>crown preparation,<br>crown finishing, inlay,<br>filing, polishing,<br>prophylaxis and<br>endodontic treatment. | A-dec NLZ electric motor<br>system is intended for use<br>in general dental<br>applications such as:<br>cutting a tooth for cavity<br>preparation, crown<br>preparation, crown<br>finishing, inlay, filing,<br>polishing, prophylaxis and<br>endodontic treatment. | Substantially<br>Equivalent | | Drive | Electronic-micromotor | Electronic-micromotor | Substantially<br>Equivalent | | Device components | Control unit with hose<br>and electrical motor | Control unit with hose and<br>electrical motor | Substantially<br>Equivalent | | Light (Motor LED) | Yes | Yes | Substantially<br>Equivalent | | Range of rotation speed | 1,000-40,000 rpm | 1,000- 40,000 rpm | Substantially<br>Equivalent | | Rotation Direction | Forward and Reverse | Forward and Reverse | Substantially<br>Equivalent | | Max.
