The description focuses on the material composition and manufacturing process of a ceramic block for dental restorations, with no mention of AI or ML technology.
No.
The device is a ceramic block used to produce dental restorations like crowns and veneers, which are prosthetic devices, not therapeutic devices.
No
The device description clearly states its purpose is for "fabrication of veneers and of crowns," which are restorative, not diagnostic, functions. It is a material used to produce dental restorations, not to identify or determine medical conditions.
No
The device description clearly states that the device is a "silicate glass ceramic block" and describes its physical properties and manufacturing process, indicating it is a hardware component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description: The description clearly states that CEREC Blocs C In are "industrially manufactured, silicate glass ceramic block used to produce crowns and veneer." These are materials used to create dental restorations that are placed in the body, not used to test samples from the body.
- Intended Use: The intended use is for "fabrication of veneers and of crowns," which are dental prosthetics.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information based on laboratory tests.
Therefore, CEREC Blocs C In falls under the category of a dental restorative material, not an in vitro diagnostic device.

Device Description
CEREC Blocs C In is an industrially manufactured, silicate glass ceramic block used to produce crowns and veneer. The block consists of an inlying, highly-chromatic dentine core and an overlying translucent enamel layer. It is grinded to custom made dental restorations using Sirona CAD/CAM systems. The block is initially manufactured in a sintered state; then, is individually processed to specification. One end plane of a block is mounted to a metal carrier that is inserted in the spindle's clamping chuck of the grinding machine.
CEREC Blocs C In are available in several colors and additional bleach color. The dental restorations obtain their individual color appearance by stain and glaze firing.

§ 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.

CEREC Blocs C In are available in several colors and additional bleach color. The dental restorations obtain their individual color appearance by stain and glaze firing.
8 Scientific Concept
The underlying scientific concept is
- · Processing dental restorations by Sirona Dental CAD/CAM System
- · Restorations are grinded from an CEREC C In by a Sirona CAM machine
Physical and Performance Characteristics 9
9.1 Design
The design of the CEREC Blocs C In is described in section 7, Device Description.
9.2 Material Used
CEREC C In ceramics constitute blocks comprised of silicate glass ceramic. One end plane of a block is mounted to a metal carrier that is inserted in the spindle's
