Intended Use
"Dental Zirconia Block (Model: HT-plus, ST, SHT, UT, 3D-Pro)" is intended for use with CAD/CAM technology to produce all ceramic dental restorations as prescribed by a dentist. All blanks are processed through dental laboratories or by dental professionals.
Device Description
"Dental Zirconia Block (Model: HT-plus, ST, SHT, UT, 3D-Pro)" is derived from zirconia powder that has been processed through various molding and sintering techniques – into their final net shapes. These blanks are then further fabricated into various prosthetic dental devices intended for use in the production of artificial teeth in fixed or removable dentures, or for jacket crowns, facings, and veneers. The zirconia powder is composed of ZrO2 , Y2O3, HfO2 and other oxides. The performance of formed zirconia dental blanks conforms to ISO 6872, Dentistry, Ceramic Materials. "Dental Zirconia Block (Model: HT-plus, ST, SHT, UT, 3D-Pro)" is ceramic dental blanks designed for the manufacture of ceramic dental prosthetic devices. The dental prosthetic devices are fabricated by CAD/CAM machining processes. All prosthetic dental devices are intended for single use applications. At the dental lab, the blanks are held to the CAD/CAM machine which is used to machine to the final dental restoration. At the completion of the machining steps, the dental restoration is fired (i.e., sintered) in the oven to harden the ZrO2 so that its final properties can be achieved. "Dental Zirconia Block (Model: HT-plus, ST, SHT, UT, 3D-Pro)" is supplied in different shapes, such as blocks, disc, and semi-disc, or customer ordered shapes. It is also supplied in the combinations of 21 different colors, and single and multi-layer aesthetic effect. The different colors are originated from the different constituent of color additives (such as Fe>O3, Er>O3); and the multilayer aesthetic effect is originated from the different padding method used in the process of dry pressing.
More Information

No
The summary describes a material (zirconia blocks) used in CAD/CAM processes for dental restorations. There is no mention of any software, algorithms, or data processing that would indicate the use of AI or ML. The performance studies focus on material properties and biocompatibility.

No
This device is a material (zirconia blocks) used to fabricate dental restorations, which are prosthetic devices, not therapeutic devices. It replaces a missing body part, which is a prosthetic function, not a therapeutic one.

No

This device is a material (zirconia blocks) used to fabricate dental restorations, not to diagnose a condition.

No

The device description clearly states that the device is a physical material (zirconia blocks) used in the fabrication of dental restorations. It is not a software program.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to produce dental restorations (artificial teeth, crowns, etc.) using CAD/CAM technology. This is a manufacturing process for a medical device (the dental restoration), not a diagnostic test performed on a biological sample.
  • Device Description: The description details the composition and processing of a material (zirconia) used to create dental prosthetics. It does not describe a device used to analyze biological samples or provide diagnostic information.
  • Lack of Diagnostic Function: The device's function is to be shaped and sintered into a dental restoration. It does not interact with or analyze biological samples to provide diagnostic results.
  • Performance Studies: The performance studies focus on the material properties of the zirconia block (strength, solubility, etc.) and its biocompatibility, which are relevant to its use as a dental restorative material, not a diagnostic device.

IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens derived from the human body (like blood, urine, tissue) to provide information for the diagnosis, monitoring, or treatment of a disease or condition. This device does not fit that description.

ર્સ્વ Device Description:

"Dental Zirconia Block (Model: HT-plus, ST, SHT, UT, 3D-Pro)" is derived from zirconia powder that has been processed through various molding and sintering techniques – into their final net shapes. These blanks are then further fabricated into various prosthetic dental devices intended for use in the production of artificial teeth in fixed or removable dentures, or for jacket crowns, facings, and veneers. The zirconia powder is composed of ZrO2 , Y2O3, HfO2 and other oxides. The performance of formed zirconia dental blanks conforms to ISO 6872, Dentistry, Ceramic Materials.

"Dental Zirconia Block (Model: HT-plus, ST, SHT, UT, 3D-Pro)" is ceramic dental blanks designed for the manufacture of ceramic dental prosthetic devices. The dental prosthetic devices are fabricated by CAD/CAM machining processes. All prosthetic dental devices are intended for single use applications. At the dental lab, the blanks are held to the CAD/CAM machine which is used to machine to the final dental restoration. At the completion of the machining steps, the dental restoration is fired (i.e., sintered) in the oven to harden the ZrO2 so that its final properties can be achieved.

"Dental Zirconia Block (Model: HT-plus, ST, SHT, UT, 3D-Pro)" is supplied in different shapes, such as blocks, disc, and semi-disc, or customer ordered shapes. It is also supplied in the combinations of 21 different colors, and single and multi-layer aesthetic effect.

The different colors are originated from the different constituent of color additives (such as Fe>O3, Er>O3); and the multilayer aesthetic effect is originated from the different padding method used in the process of dry pressing.

5.7 Indications for Use:

"Dental Zirconia Block (Model: HT-plus, ST, SHT, UT, 3D-Pro)" is intended for use with CAD/CAM technology to produce all ceramic dental restorations as prescribed by a dentist. All blanks are processed through dental laboratories or by dental professionals.
