The description focuses on the material (PMMA) and the CAD/CAM manufacturing process, with no mention of AI or ML for design, analysis, or manufacturing optimization.
No
The device is described as milling blanks for making long-term temporary crown and bridge work, not for treating a disease or condition.
No
Explanation: This device is a milling blank used to create temporary dental restorations, not to diagnose a condition or disease.
No
The device is a physical milling blank made of polymethylmethacrylate, not software. While it is used in a process involving CAD/CAM technology, the device itself is a material.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for creating long-term temporary crown and bridge work using a CAD/CAM technique. This is a manufacturing process for a dental prosthetic, not a diagnostic test performed on a biological sample.
- Device Description: The device is a milling blank made of PMMA, used to fabricate dental restorations. The process described involves scanning, CAD/CAM design and milling, and finishing. This is a fabrication process, not a diagnostic procedure.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting diseases, conditions, or states of health, or providing information for diagnosis, monitoring, or treatment decisions based on such analysis.
The device is a material used in the fabrication of a medical device (a dental prosthetic), but it is not an IVD itself.

Intended Use / Indications for Use
ZENO®PMMA Discs are milling blanks consisting of polymethylmethacrylate. They are designed for making long-term temporary crown and bridge work and have to be machined with the CAD/CAM technique. ZENO PMMA Discs are recommended for manufacturing substructures of single tooth and bridgework with one or two pontics.

Device Description
ZENO PMMA Discs (A3/B1) are milling blanks composed of hot cured polymethylmethacrylate (PMMA). They are intended to be used by professional dental technicians for making long-term temporary crowns and bridgeworks for the sole use of particular patients.
ZENO PMMA Discs can be machined in all machines of the ZENO Tec system. The manufacturing process of the long-term temporary crowns and bridges consists of different steps. At first the model has to be scanned. In the next step, the restoration has to be designed virtually with the help of the CAD technology. Thereafter, the realization of this design has to be carried out by the CAM technology. In a final step the restoration can be individually characterised with dental veneering composites for improving the aesthetics and it can be pre- and high shine polished.
The ZENO PMMA Discs are offered in two different shades (A3, B1) and thicknesses.

Device description
ZENO PMMA Discs (A3/B1) are milling blanks composed of hot cured polymethylmethacrylate (PMMA). They are intended to be used by professional dental technicians for making long-term temporary crowns and bridgeworks for the sole use of particular patients.
ZENO PMMA Discs can be machined in all machines of the ZENO Tec system. The manufacturing process of the long-term temporary crowns and bridges consists of different steps. At first the model has to be scanned. In the next step, the restoration has to be designed virtually with the help of the CAD technology. Thereafter, the realization of this design has to be carried out by the CAM technology. In a final step the restoration can be individually characterised with dental veneering composites for improving the aesthetics and it can be pre- and high shine polished.
The ZENO PMMA Discs are offered in two different shades (A3, B1) and thicknesses.
Recommended application
With the introduction of the ZENO PMMA Discs, Wieland Dental+Technik offers to the customer for the ZENO TEC System the possibility of producing long-term temporary crowns and bridgeworks with one or two pontics. These could be used, for example, with patients who should receive an implant -supported restoration, in which the long-term temporary restoration has a prophylactic function to prevent any change of the position of the abutment-teeth. In addition, the teeth are protected by the restoration against the influence of bacterial, toxic as well as thermal effects. Furthermore, it becomes possible to check the occlusion, the phonetics as well as the aesthetics.
Comparison with the predicate device
ZENO PMMA Discs are substantially equivalent to the dental device VITA CAD-TEMP. Both devices are acrylate polymers and have identical indication for use, comparable physical, biological, and chemical properties and the same prophylactic, diagnostic and aesthetic function.
Due to the high polymerization grade and excellent material properties of the ZENO PMMA Discs, the restorations possess a high-level safety and effectiveness. ZENO PMMA Discs therefore are as safe, as effective, and performs as well as 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 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.
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.
