Intended Use
Perfit ZR ST Dental Zirconia blank and Perfit ZR UT Dental Zirconia blank are used for dental restorations using different CAD / CAM or manual milling machines. All blanks are processed through dental laboratories or by dental professionals.
Device Description
The Perfit ZR ST Dental Zirconia blank and Perfit ZR UT Dental Zirconia blank consists of zirconium oxide which compresses ceramic for milling, grinding, and further firing. It is normally pre-sintered and milled by dental technician with CAD/CAM machine for shaping artificial teeth such as crowns, bridges, veneers, inlay etc. The Perfit ZR ST Dental Zirconia blank and Perfit ZR UT Dental Zirconia blank are disc shaped zirconia oxide blanks made available in different versions and chemical compositions of various colors, shades and dimensions and will further process the discs by milling them to make final dental restorations such as crowns, bridges, veneers, inlays and on lays based on the anatomical rendering of the patient's teeth using CAD/CAM equipment. 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. They are available in different models that differ in various specification and color. There are white zirconia products(W) and colored zirconia products, and colored zirconia is also divided into Monolayer(A1, A2, A3.5, A4, B1, B2, B3, B4, C1, C2, C3, C4, D2, D3, D4) color products , Shade multi-layer(A1 SM, A2 SM, A3 SM, A3.5 SM, A4 SM, B1 SM, B2 SM, B3 SM, B4 SM, C1 SM, C2 SM, C3 SM, C4 SM, D2 SM, D3 SM, D4 SM) color products and Trans&Shade multi-layer(A1 TM, A2 TM, A3 TM, A3 TM, A4 TM, B1 TM, B2 TM, B3 TM, B4 TM, C1 TM, C2 TM, C3 TM, C4 TM, D2 TM, D3 TM, D4 TM) color products. The white zirconia is composed of ZrO2+HfO2+Y2O3 and an additional inorganic pigment: Al203 and Other oxide. The color zirconia products are derived from the same zirconia powder as the regular white zirconia powder, with the addition of very small amount of inorganic pigments: Fe203 +Pr203 +Er203. The inorganic pigments generate the color on the prosthetic dental device, after sintering at dental labs, that matches natural color of patient's teeth. The composition of the Dental Zirconia Blocks including the white zirconia and the color zirconia conforms to ISO 13356:2015, Implants for surgery -Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP) and the performance conforms to ISO 6872:2015/Amd1:2018, Dentistry: Ceramic Materials.

The device description focuses on the material composition and physical properties of dental zirconia blanks used in traditional CAD/CAM milling processes. There is no mention of AI or ML in the intended use, device description, or performance studies.

No
This device is a material (zirconium oxide blank) used to manufacture dental restorations like crowns and bridges, not a device that directly provides therapy or treatment to a patient.

No
The device is a material (zirconium oxide blank) used for manufacturing dental restorations, not for diagnosing a condition or disease.

No

The device is a physical dental blank made of zirconium oxide, intended for milling into dental restorations. It is a hardware component, 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 for creating dental restorations (crowns, bridges, veneers, etc.) using CAD/CAM or manual milling machines. This is a manufacturing process for a medical device that will be implanted or placed in the body.
  • Device Description: The description details the material composition and how the blanks are processed to form artificial teeth. This is about the physical creation of a prosthetic device.
  • Lack of IVD Characteristics: The text does not mention any of the key characteristics of an IVD, such as:
    • Analyzing samples from the human body (blood, urine, tissue, etc.).
    • Providing information about a patient's health status, diagnosis, or disease.
    • Using reagents or calibrators for testing.

The device is a material used in the creation of a dental prosthetic, which is a medical device, but it is not an in vitro diagnostic device.

It is normally pre-sintered and milled by dental technician with CAD/CAM machine for shaping artificial teeth such as crowns, bridges, veneers, inlay etc.

The Perfit ZR ST Dental Zirconia blank and Perfit ZR UT Dental Zirconia blank are disc shaped zirconia oxide blanks made available in different versions and chemical compositions of various colors, shades and dimensions and will further process the discs by milling them to make final dental restorations such as crowns, bridges, veneers, inlays and on lays based on the anatomical rendering of the patient's teeth using CAD/CAM equipment. 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.

They are available in different models that differ in various specification and color. There are white zirconia products(W) and colored zirconia products, and colored zirconia is also divided into Monolayer(A1, A2, A3.5, A4, B1, B2, B3, B4, C1, C2, C3, C4, D2, D3, D4) color products , Shade multi-layer(A1 SM, A2 SM, A3 SM, A3.5 SM, A4 SM, B1 SM, B2 SM, B3 SM, B4 SM, C1 SM, C2 SM, C3 SM, C4 SM, D2 SM, D3 SM, D4 SM) color products and Trans&Shade multi-layer(A1 TM, A2 TM, A3 TM, A3 TM, A4 TM, B1 TM, B2 TM, B3 TM, B4 TM, C1 TM, C2 TM, C3 TM, C4 TM, D2 TM, D3 TM, D4 TM) color products.

The white zirconia is composed of ZrO2+HfO2+Y2O3 and an additional inorganic pigment: Al203 and Other oxide. The color zirconia products are derived from the same zirconia powder as the regular white zirconia powder, with the addition of very small amount of inorganic pigments: Fe203 +Pr203 +Er203.

Device Description and Statement of Intended Use 4.

The Perfit ZR ST Dental Zirconia blank and Perfit ZR UT Dental Zirconia blank consists of zirconium oxide which compresses ceramic for milling, grinding, and further firing. It is normally pre-sintered and milled by dental technician with CAD/CAM machine for shaping artificial teeth such as crowns, bridges, veneers, inlay etc.

The Perfit ZR ST Dental Zirconia blank and Perfit ZR UT Dental Zirconia blank are disc shaped zirconia oxide blanks made available in different versions and chemical compositions of various colors, shades and dimensions and will further process the discs by milling them to make final dental restorations such as crowns, bridges, veneers, inlays and on lays based on the anatomical rendering of the patient's teeth using CAD/CAM equipment. 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.

They are available in different models that differ in various specification and color. There are white zirconia products(W) and colored zirconia products, and colored zirconia is also divided into Monolayer(A1, A2, A3.5, A4, B1, B2, B3, B4, C1, C2, C3, C4, D2, D3, D4) color products , Shade multi-layer(A1 SM, A2 SM, A3 SM, A3.5 SM, A4 SM, B1 SM, B2 SM, B3 SM, B4 SM, C1 SM, C2 SM, C3 SM, C4 SM, D2 SM, D3 SM, D4 SM) color products and Trans&Shade multi-layer(A1 TM, A2 TM, A3 TM, A3 TM, A4 TM, B1 TM, B2 TM, B3 TM, B4 TM, C1 TM, C2 TM, C3 TM, C4 TM, D2 TM, D3 TM, D4 TM) color products.

The white zirconia is composed of ZrO2+HfO2+Y2O3 and an additional inorganic pigment: Al203 and Other oxide. The color zirconia products are derived from the same zirconia powder as the regular white zirconia powder, with the addition of very small amount of inorganic pigments: Fe203 +Pr203 +Er203. The inorganic pigments generate the color on the prosthetic dental device, after sintering at dental labs, that matches natural color of patient's teeth.

Our device is essentially identical to the predicate device in terms of indications for use, design, material, and processing between our device and the predicate devices. We have some minor differences are compared with the predicate device. One is that the predicate device includes rod form more than ours. Shape excluding rod form can be considered the same as our product. Another one is that our device including not only single layer color product but also including multilayer color product to satisfy the aesthetic needs. The different colors are originated from the different constituent of color additive (such as Fe203, Er203, and the different aesthetic effects are originated from the different padding method used in the process of dry pressing, they are very small amount(
