The summary describes dental ceramic blanks and coloring liquids, which are materials used in CAD/CAM or copy milling systems for creating dental restorations. There is no mention of any software, algorithms, or data processing that would indicate the use of AI or ML. The performance studies focus on material properties and shelf life.
No
Explanation: This device is a dental blank used to produce restorations like crowns, inlays, veneers, and bridges. While these restorations treat dental issues, the blank itself is a material for manufacturing, not a device that directly performs therapy.
No
This device is a material (ceramic blanks and coloring liquids) used for the fabrication of dental prosthetics (crowns, inlays, veneers, bridges). It is not used to diagnose a medical condition.
No
The device description clearly states it is a ceramic blank and associated liquids for creating dental restorations, which are physical materials, not software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use is for the preparation of dental restorations (crowns, inlays, veneers, bridges) and the coloring of these restorations. This is a manufacturing process for a medical device that will be implanted or placed in the body, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The device is a ceramic blank and a coloring liquid used to create dental prosthetics. It's a material used in the fabrication of a medical device.
- Lack of Diagnostic Purpose: There is no mention of the device being used to analyze a biological sample (blood, urine, tissue, etc.) to provide information for the diagnosis, monitoring, or treatment of a disease or condition.
- Performance Studies: The performance studies focus on the material properties (bending strength, solubility, radioactivity) and biocompatibility of the final dental restoration, which are relevant to its function as a medical device, not its performance as a diagnostic test.
In summary, the Z-CAD® smile blanks and liquids are materials and components used to manufacture dental prosthetics, which are considered medical devices, but they do not fit the definition of an In Vitro Diagnostic device.

Device Description
Z-CAD® smile ceramic blanks are indicated for the production of dental-prosthetic restorations. The blanks named above can be machined with CAM, CAD/CAM or copy milling systems commonly used in dental medical technology to produce dental-prosthetic restorations made from zirconium oxide. This material offers excellent properties with regards to bio-compatibility, stability and aesthetics, which make it the material of choice for the production of restorations for dental crowns, inlays, onlays, veneers, and up to three unit bridges, which in turn combine the advantages of conventional casting technology and full ceramics. Dental technicians are therefore in a position to offer patients the extra added value when finishing the prosthesis.
Metoxit Z-CAD® smile Blanks also includes Z-CAD® Liquids smile-TC. Z-CAD® Liquids smile-TC are ready for use water-based products, which are applied to the milled restauration prior to sintering to achieve individual shades. These liquids are specifically formulated for the dyeing of Z-CAD® smile blanks from Metoxit AG.

(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)

Dear Dr. Gian-Carlo Gullo:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.
