Device Description
The Hu-Friedy® brand Symmetry IQ Ultrasonic Scalers are similar to the Ultrasonic Scalers of the predicate device listed above. These devices are intended for use by dental professionals only. These devices generate ultrasonic vibrations intended for use in dental applications such as scaling, periodontal therapy, root canal treatment and cavity preparation. Hu-Friedy will purchase the generators from NSK, Inc. (Nakanishi) and own brand private label the device. The modifications to the Hu-Friedy product are cosmetic in nature and consist mainly of new shape and design to the housing of the control unit. All of the internal electrical and technical specifications are identical to the marketed NSK units. Hu-Friedy currently has a 510k (K053178) approval for the Symmetry line of piezoelectric tips that are compatible with Satelec and NSK piezoelectric ultrasonic scalers. The addition of the Symmetry IQ generators and handpiece will complete our ultrasonic piezo scaling product line. The Symmetry IQ Ultrasonic Scalers have essentially the same design as the predicate device's ultrasonic generators. The Symmetry IQ 2000 series is equivalent to the Varios 150 Lux (Optic), which is an integrated version of the Varios 350 Lux (Optic) to be used in the delivery tray table as a built in system. The Symmetry IO 3000 series is equivalent to the combination of the Varios 550 control unit with the handpiece used in the Varios 350 Lux (Optic). The Symmetry IQ 3000 unit is based on the NSK Varios 560 which is currently pending FDA 510k approval. The addition of a silicone grip to the ultrasonic generator handpiece used in both models is the only significant change and the reason for the new 510k application.
More Information

No
The description focuses on the mechanical and electrical aspects of ultrasonic scaling, explicitly stating modifications are cosmetic and internal specifications are identical to predicate devices. There is no mention of AI/ML terms or functionalities.

Yes
The device is intended for dental applications such as scaling, periodontal therapy, root canal treatment, and cavity preparation, which are therapeutic medical procedures.

No

The device is described as generating ultrasonic vibrations for dental applications like scaling, periodontal therapy, root canal treatment, and cavity preparation, which are therapeutic and restorative procedures, not diagnostic ones.

No

The device description explicitly states it is an ultrasonic scaler that generates ultrasonic vibrations and includes physical components like generators, handpieces, and a control unit. It also mentions hardware modifications and testing.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device is for "dental applications such as scaling, periodontal therapy, root canal treatment and cavity preparation." These are procedures performed directly on the patient's teeth and gums.
  • Device Description: The description focuses on generating "ultrasonic vibrations" for these dental procedures.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (like blood, urine, or tissue) in vitro (outside the body) to provide information about a patient's health.

IVD devices are specifically designed for testing biological samples to diagnose, monitor, or screen for diseases or conditions. This device's function is entirely focused on mechanical action within the oral cavity.

Hu-Friedy performed laboratory tests such as a sterilization study of the handpiece (study #582), biocompatibility testing of the silicone grip(study #574) and ISO 22374 life testing(study#579) of the ultrasonic unit to determine the safety of the Symmetry IQ generators and handpiece.

The decision to private label NSK ultrasonic generators was made after market research and a focus group study(study #581) were conducted by Hu-Friedy. The key features of the Varios line of NSK scalers such as fiber-optic lighted handpieces, easy to read touchpad controls, quick connect components and broad range of power settings met the Hu-Friedy customer requirements.

Dear Mr. Dunn:

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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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 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); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
