This document is an FDA 510(k) clearance letter for a dental device, not a study report or technical specification document. Therefore, it does not contain the detailed information required to answer your request about acceptance criteria and a study proving a device meets those criteria.

The letter explicitly states: "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..."

This means the FDA granted clearance based on substantial equivalence to existing devices, not necessarily on a new standalone study proving performance against defined acceptance criteria for a novel device.

Therefore, I cannot provide the requested information, which would typically be found in a clinical study report or a detailed test report. The document only contains:

• Device Name: IPS e.max® CAD Crystall/Connect and IPS e.max® CAD Crystall/Add-on Connect (for CAD-On Technique)
• Regulation Number: 21 CFR 872.6660
• Regulation Name: Porcelain Powder for Clinical use

The acceptance criteria, study details, sample sizes, ground truth establishment, and expert information are not present in this regulatory clearance letter.
