rainbow™ Trans is used in the manufacture of a dental core.
rainbow™ Trans is a partially sintered dental ceramic made out of colored ZrO2(Y-TZP). rainbow™ Trans is milled into cores of artificial teeth and then is finally sintered in a furnace to harden the ZrO2. Then, the core is layered with porcelain to make a finished tooth.
The provided document describes the predicate device and the new device (rainbow™ Trans) being submitted for 510(k) premarket notification. The study provided is a comparison of technical characteristics and performance data against established standards, rather than a clinical study involving human subjects or AI performance. Therefore, many of the requested categories (sample size for test set, number of experts, adjudication method, MRMC comparative effectiveness, standalone performance, training set details) are not applicable or cannot be extracted from this type of regulatory submission.
However, I can extract the acceptance criteria and reported device performance from the "Performance Data" section.

§ 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.
