The summary describes a dental ceramic material and system for fabricating restorations, with no mention of software, algorithms, or any technology that would typically incorporate AI/ML.
No
The device is a dental press ceramic system used by dental technicians to fabricate all-ceramic restorations and Prostheses. It is a material used to create dental devices, not a device that directly provides therapy.
No
Explanation: This device is a dental ceramic system used to fabricate all-ceramic restorations. It is a manufacturing material, not a device that diagnoses medical conditions.
No
The device description clearly states that the system consists of "solid glass ceramic (porcelain) pellets" and "porcelain powders," which are physical materials used in the fabrication of dental prostheses. This indicates it is a hardware/material-based device, not software-only.
Based on the provided text, the device "PressX Zr" is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The intended use and device description clearly state that PressX Zr is a dental ceramic used by dental technicians to fabricate dental restorations (crowns, bridges, inlays, onlays, veneers) for direct use in a patient's mouth. It is a material used to create a physical prosthesis, not to analyze biological samples.
- The purpose of IVDs is to provide information about a physiological or pathological state. PressX Zr's purpose is to restore the function and aesthetics of teeth, not to diagnose or monitor a medical condition.
The text describes a dental material used in the fabrication of dental prosthetics, which falls under the category of dental devices, not in vitro diagnostics.

Intended Use / Indications for Use
PressX Zr is a dental press ceramic system that is intended to be used by professional dental technicians to manufacture all-ceramic dental prostheses for the sole use of particular patients.
The indications of the all -ceramic restorations, which are fabricated with zirconium dioxide frameworks and PressX Zr are mainly determined by the specifications of the zirconium dioxide framework materials and are fixed by their manufacturers. Usually, zirconium dioxide frameworks are intended for manufacturing dental crowns and bridges for the anterior and posterior region.
Additionally, PressX Zr can be used to manufacture all-ceramic inlays, onlays, and veneers without zirconium dioxide frameworks.
PressX Zr is a pressable dental ceramic that can be used by dental technicians to fabricate all-ceramic restorations by pressing-over zirconium dioxide frameworks. The indications of these all-ceramic restorations are defined by the manufacturers of the zirconium dioxide (ZrO2) framework material, and normally encompass dental crowns and bridges.
The coefficient of thermal expansion [CTE (25 - 500°C]] of these zirconium dioxide (ZrO2) frameworks has to equal approximately 10 x 10°K1
In addition, PressX Zr can be used to manufacture all-ceramic inlays, onlays, and veneers without zirconium dioxide frameworks.

Device Description
PressX Zr is a dental press ceramic system that is intended to be used by professional dental technicians to manufacture all-ceramic dental prostheses for the sole use of particular patients.
The PressX Zr system consists of solid glass ceramic (porcelain) pellets, which are intended to be pressed onto zirconium dioxide frameworks at high temperature, and of porcelain powders, which are intended to stain these all-ceramic restorations, individually.
After overpressing, the restoration can be finished either by using the staining- or by using the layering-technique. For staining, the PressX Zr powders (Bodystains + Glaze) which are components of the PressX Zr system have to be applied. For lavering, the ZIROX -- powders (a product of Wieland Dental + Technik, K051249) have to be used.
PressX Zr can be pressed onto any zirconium dioxide material, which has a coefficient of thermal expansion [CTE (25-500°C]] of about 10 x 10° K'.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Compared to the predicate device, PressX Zr has a higher flexural strength according to ISO 6872, and "standard crowns" made of PressX Zr have a significantly higher fracture resistance.
For this reason, PressX Zr is at least as safe, as effective and performs as well or better than the predicate device.

Indications for use
The indications of the all -ceramic restorations, which are fabricated with zirconium dioxide frameworks and PressX Zr are mainly determined by the specifications of the zirconium dioxide framework materials and are fixed by their manufacturers. Usually, zirconium dioxide frameworks are intended for manufacturing dental crowns and bridges for the anterior and posterior region.
Additionally, PressX Zr can be used to manufacture all-ceramic inlays, onlays, and veneers without zirconium dioxide frameworks.
There is no limitation of the device regarding the patient population, in which commonly known contraindications for all-ceramic restorations, like bruxism, have to be considered by the dentists.
Comparison with the predicate device
PressX Zr equals the predicate device with regard to the intended use, material constituents, application process (overpressing technique), recommended framework material, biocompatibility and chemical solubility.
Compared to the predicate device, PressX Zr has a higher flexural strength according to ISO 6872, and "standard crowns" made of PressX Zr have a significantly higher fracture resistance.
For this reason, PressX Zr is at least as safe, as effective and performs as well or better than the predicate device.

Dear Dr. Polzer:
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 Novinatio Act (Act) that do not require approval of a premarket approval application (PMA). Tour 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
