rainbow™ LS Block can be used for manufacturing Crown, Veneer, Inlay and Onlay.
rainbow™ LS Block is a dental ceramic made out of Lithium disilicate. rainbow™ LS Block is milled into cores of teeth and then is fired in a furnace to harden the Li2Si2O3. Then, the core is layered with porcelain to make a finished tooth.
The provided information describes the acceptance criteria and performance data for a dental ceramic device named "rainbow™ LS Block," submitted for 510(k) premarket notification. The study primarily relies on bench testing and biocompatibility testing to demonstrate substantial equivalence to a predicate device (IPS e.max CAD).
Here's the breakdown of the information that can be extracted from the document, organized according to your requested points.

§ 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.
