The summary describes dental zirconia blocks used with CAD/CAM technology, focusing on material properties and biocompatibility testing. There is no mention of AI or ML.
Yes.
The device is used to produce dental restorations (implants), which are devices intended to affect the structure or function of the body, falling under the definition of a therapeutic device.
No
This device is Dental Zirconia, used with CAD/CAM technology to produce all ceramic dental restorations. It is a material for manufacturing prosthetics, not a tool for diagnosis.
No
The device description clearly states the device is "Dental Zirconia" in disc shape, made of zirconia powder, and intended for use with CAD/CAM technology to produce physical dental restorations. This describes a physical material, not software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to produce dental restorations (crowns, bridges, inlays, veneers) using CAD/CAM technology. This is a manufacturing process for a medical device that will be placed in the patient's mouth.
- Device Description: The device is described as dental zirconia material used to fabricate these restorations. It's a material for creating a physical device.
- Lack of Diagnostic Purpose: There is no mention of the device being used to diagnose a disease or condition, or to examine specimens derived from the human body.
IVD devices are used to perform tests on samples (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This dental zirconia material does not fit that description.

Device Description
The Dental Zirconia are intended for use with CAD/CAM technology to produce all ceramic dental restorations as prescribed by a dentist.
The Dental Zirconia divided into two categories: Unshaded (Model: DUT) and Pre-Shaded (Model: DUTC).
Both Unshaded Dental Zirconia (Model: DUT) and Pre-Shaded Dental Zirconia (Model: DUTC) are available in discs shape, and in various specifications, which are shares same diameter (98 mm) and combinations of height (10-25 mm).
The color model for pre-shaded dental zirconia includes A1; A2; A3; A3.5; B2; C2; 1M1; 1M2; 2L1.5; 2M2; 3M2; 3M3; 4M2; 5M3 for difference color.
Both Unshaded Dental Zirconia (Model: DUT) and Pre-Shaded Dental Zirconia (Model: DUTC) have same base materials and derived from zirconia powder that has been processed via uni-aixial die pressing, followed by isostatic pressing, to achieve various shapes of uniform density and distribution. The ceramic blocks can be fabricated into various prosthetic dental devices.
The zirconia powder of Dental Zirconia is composed of ZrO2+Y2O3+HfO2+Al2O3. The performance of the Dental Zirconia conforms to ISO 6872:2015 Dentistry: Ceramic Materials.
The Dental Zirconia are disposable device, and provided as non-sterile

Table 1 General Comparison
The proposed device is highly similar to the predicate device in the terms of indication for use, materials processing, color, sterile etc.. The only differences between the proposed and predicate device are:
- The subject device only has disc, while the predicate device has blocks, disc and rod. This a. difference does not raise any safety or efficacy concerns, because both proposed and predicate has the disc shapes, and the proposed device has no other shapes outside the scope of predicate device.
- Both subject device and predicate device has various dimension. This difference does no raise an b. safety or efficacy concerns, because no matter what size will not affect the physical/mechanical and biocompatibility properties of the proposed product, both the subject and predicate device have similar physical/mechanical and biocompatibility properties that met the requirements of ISO 6872 and ISO 10993.
