AI/ML Overview

The provided text describes the regulatory clearance of a dental material, BruxZir® NOW, and its comparison to a predicate device, Perfit FS Dental Zirconia Fully Sintered Block. The information primarily focuses on demonstrating substantial equivalence rather than a study proving the device meets acceptance criteria in the context of an AI/ML device.

However, I can extract the relevant performance data and acceptance criteria as described for the dental material itself. The document does not describe an AI/ML device, an MRMC study, or a standalone algorithm performance study. It's about a physical dental material.

Here's the information based on the provided text, interpreted for the dental material:

§ 872.6660 Porcelain powder for clinical use.

(a)
Identification. Porcelain powder for clinical use is a device consisting of a mixture of kaolin, felspar, quartz, or other substances intended for use in the production of artificial teeth in fixed or removable dentures, of jacket crowns, facings, and veneers. The device is used in prosthetic dentistry by heating the powder mixture to a high temperature in an oven to produce a hard prosthesis with a glass-like finish.(b)
Classification. Class II.
