Not Found
This document is a 510(k) clearance letter from the FDA for a dental device called "KATANA Zirconia." It confirms that the device has been found substantially equivalent to a predicate device for its intended use.
The letter does not provide details about a study with acceptance criteria, device performance, sample sizes, expert qualifications, or ground truth establishment. This is a regulatory clearance document, not a clinical study report.
Therefore, I cannot provide the requested information based on the provided text. The document confirms market clearance but does not contain the specific study details you've asked for.

Dear Mr. Wasserman:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

In addition, FDA may publish further announcements concerning your device in the Federal Register.
