rainbow™ Shade is a pre-sintered zirconia(Y-TZP) block for fabrication of single-tooth and bridgework restoration.
rainbow™ Shade is a dental ceramic made out of colored ZrO2(Y-TZP). rainbow™ Shade is milled into cores of teeth and then is fired in a furnace to harden the ZrO2. Then, the core is layered with porcelain to make a finished tooth.
The provided text describes the performance data for a dental ceramic device named "rainbow™ Shade." It includes acceptance criteria and results from various tests, primarily focusing on biocompatibility and physical properties.
Here's an analysis of the provided information regarding acceptance criteria and the study that proves the device meets them:

8. The sample size for the training set
This section is not applicable. The device is a physical material, not a machine learning model, so there is no concept of a "training set" in this context.
9. How the ground truth for the training set was established
This section is not applicable for the same reason as point 8.
§ 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.
