The device description clearly states it is a "millable dental ceramic material made of zirconia" and describes its physical forms (barrels, discs, rectangular, special shapes) and dimensions. This indicates it is a physical material, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the manufacturing of dental prostheses, inlays, onlays, and veneers. This is a structural and restorative purpose, not for diagnosing a condition or analyzing a biological sample.
- Device Description: The device is a millable dental ceramic material. This is a material used in the creation of a medical device (the dental restoration), not a device that performs a diagnostic test.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring specific substances (analytes)
- Providing information for diagnosis, monitoring, or screening
The device is a material used in the manufacturing process of a dental medical device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
In consideration of the International Standard ISO 10993-1, Biological Evaluation of Medical Devices, Part 1: Evaluation and Testing, the same tests performed on the predicate device were performed on the final finished subject device to evaluate: In-vitro cytotoxicity, Skin sensitization, Mutagenicity, Irritation. Biocompatibility testing demonstrated that no issue of biocompatibility arises. Preattau Anterior was tested according to ISO 6872:2008 and is classified as Type II Class a&b and 2a esthetic dental ceramic. The device has been tested for flexural strength, chemical solubility, fracture toughness and CTE.
The results of nonclinical tests demonstrate that the device is equivalent to the predicate device.

Dear Mr. Bisson:
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. 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.

DEVICE DESCRIPTION
PRETTAU® ANTERIOR T0 is a millable dental ceramic material made of zirconia.
PRETTAU® ANTERIOR TO is destined for manufacture with CAD/CAM technology of metal free single-unit anterior and posterior prostheses, implant superstructures, inlays, onlays and veneers as fully anatomical restoration as well as for reduced structures for veneering with ceramics. The device is compatible with commercially available dental CAD/CAM systems must
be validated by the user. The blocks are suitable for all milling units which are able to process presintered zirconia and which have the proper clamping device for the corresponding blank. PRETTAU® ANTERIOR TO is marketed in 25 different outer shapes, i.e. barrel, discs, rectangular, and special shapes; the blocks are produced in various heights from 10mm to 50 mm for each shape.
DISCUSSION OF NON CLINICAL TESTS
In consideration of the International Standard ISO 10993-1, Biological Evaluation of Medical Devices, Part 1: Evaluation and Testing, the same tests performed on the predicate device were performed on the final finished subject device to evaluate: In-vitro cytotoxicity, Skin sensitization, Mutagenicity, Irritation. Biocompatibility testing demonstrated that no issue of biocompatibility arises. Preattau Anterior was tested according to ISO 6872:2008 and is classified as Type II Class a&b and 2a esthetic dental ceramic. The device has been tested for flexural strength, chemical solubility, fracture toughness and CTE.
The results of nonclinical tests demonstrate that the device is equivalent to the predicate device.
SUBSTANTIAL EQUIVALENCE
PRETTAU® ANTERIOR TO equals the predicate device with respect to the indications for use and the fundamental technology, relating to the use of zirconia blocks, the application process (CAD/CAM technology), the biocompatibility and other technical aspects.
The differences in the composition between the new device and the predicate relate to the percentages of yttrium oxide and they have effect on the crystal structure and consequently on the translucency of the device; they have no material effects on the biocompatibility of the device. The composition has not been changed in way that may adversely impact the equivalence with the predicate device.
The PRETTAU® ANTERIOR T0 has a lower mechanical strength than the predicate device (ICE Zirkon Transluzent Plus, 1200 Mpa), due to the fact that the material is completely stabilized with yttrium oxide in order to achieve higher translucency. The resistance to bending is however 600 Mpa, still well above the limits set by ISO 6872:2008.
