1Derful™ Zirconia blanks are indicated for use in prosthetic dentistry to create porcelain (ceramic) prostheses (dentures, crowns and bridges) in the anterior applications and not used solely as an implant. 1Derful™ Zirconia blanks are intended to be milled and fully sintered by Dental Professional or Dental Laboratory before use.
1Derful™ Zirconia are disc shaped dental porcelain zirconia oxide blanks that come in various sizes that are used in custom restorations by the dental laboratory. The dental laboratory will further process the blank by milling the blank based upon the anatomically rendering of the patient's teeth (done at the dental office) through "Computer Aided Drafting/ Computer Aided Machining (CAD/CAM). Once the custom rendered blank is milled the product is fully sintered and colored (if required) and fitted to the patient's teeth as dentures, crowns or bridges. 1Derful™ Zirconia blanks are composed of zirconia ceramics (ZrO2) based on yttria- stabilized tetragonal zirconia (Y-TZP). Shading oxide will also be used to create the need shade in the disc. These three oxide materials are Fe2O3, ErO3, Co3O4 & Er2O3.
The provided text describes the non-clinical testing performed for the 1DERFUL™ HS & 1DERFUL™ HT Zirconia blanks. It does not mention any clinical studies, multi-reader multi-case studies, or human-in-the-loop performance. Therefore, information regarding those aspects cannot be extracted.
Here's a breakdown of the requested information based on the provided text:

§ 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.
