Operative Dental Unit Accessories include air compressors and vacuum units connected to dental operative units to provide compressed air and vacuum capability for powering and driving other attached dental devices. These accessories are essential supporting components of the dental operatory setup and are classified as FDA Class 1 devices under 21 CFR 872.6640, subject to general controls. The product code is NRD, falling within the Dental medical specialty. These devices are exempt from premarket notification (510(k)) and do not carry implant or life-sustaining support designations.

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
