Intended Use
Erran Dental Zirconia are indicated for the production of artificial teeth in fixed or removable dentures, or for jacket crowns, facing, and veneers.
Device Description
Normally, Erran Dental Zirconia are offered in blocks and powder and the size as shown below in Table 5-1, and are similar to the sizes and shapes of the predicate device. There are two types of our device, one is block, another is powder. The main difference is that the blocks are made by powder, zirconia blocks is prepared and have a fixed shape, while zirconia powder is used to directly product the shape of the tooth. Erran Dental Zirconia are derived from Zirconia powder that has been processed into their final net shapes. Erran Dental Zirconia have are then being further fabricated in to all-ceramic restoration such as crowns, bridge, veneers, inlay/onlay. The zirconia powder is composed of ZrO2+Y2O3+HfO2+Al2O3 with its composition conforms to ISO13356-2015, Implants for Surgery-Ceramic Materials Based in Yttria-Stabilized Tetragonal Zirconia(Y-TZP). The performance of the dental zirconia conforms to ISO 6872-2015, Dentistry: Ceramic Materials.

No
The device description focuses on the material composition and physical form of dental zirconia, with no mention of software, algorithms, or data processing that would indicate the use of AI/ML. The performance studies described are standard bench testing for material properties.

No
The device is a material (zirconia blocks and powder) used to produce dental restorations, not a device that provides therapy.

No

The device is a material (zirconia blocks and powder) used for the production of artificial teeth, which are used as a restorative solution rather than for diagnosing a condition.

No

The device description clearly states that the device is offered in physical forms (blocks and powder) and is composed of specific materials (ZrO2+Y2O3+HfO2+Al2O3). It is a physical material used for creating dental restorations, not a software application.

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 production of artificial teeth in fixed or removable dentures, jacket crowns, facings, and veneers. This is a direct medical device used for restoration and prosthetics within the mouth.
  • Device Description: The device is described as zirconia blocks and powder used to fabricate dental restorations. This is a material used in the manufacturing process of a medical device, not a diagnostic test.
  • Lack of Diagnostic Function: There is no mention of the device being used to test samples from the human body (blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
  • Testing: The testing described focuses on the material properties and biocompatibility of the zirconia, not on its ability to detect or measure biological markers.

IVD devices are specifically designed to perform tests on samples taken from the human body to provide diagnostic information. This device is a material used to create dental prosthetics, which falls under the category of a medical device, but not an IVD.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Bench testing was performed per ISO 6872-2015 and internal procedures to ensure that the Erran Dental Zirconia met its specification. All tests were verified to meet acceptance criteria. Biocompatibility testing was performed to verify the equivalent safety of the materials that are used.

Tests were conducted following the recommended procedures outline in the FDA recognized consensus standard of ISO 6872-2015, ISO7405-2008 and ISO 10993-1-2009, and results meet all relevant requirements in the test standards.

Key results:

  • Chemical Composition(%): Meet the ISO 13356-2015
  • Appearance: There is no spot cracks and foreign matter on the surface of Erran Dental Zirconia.
  • Size(mm): Meet the requirement.
  • Density (g/cm³): Meet the requirement.
  • Sintering density (g/cm³): 6.025 (Not less than 6.02)
  • Fracture Toughness (post sintering) (MPa): The samples met the criteria. (At least 8 samples of the 10 samples have a fracture toughness greater than 800)
  • Chemical solubility (µg/cm²): 12.42 (

§ 872.6660 Porcelain powder for clinical use.

(a)
Identification. Porcelain powder for clinical use is a device consisting of a mixture of kaolin, felspar, quartz, or other substances intended for use in the production of artificial teeth in fixed or removable dentures, of jacket crowns, facings, and veneers. The device is used in prosthetic dentistry by heating the powder mixture to a high temperature in an oven to produce a hard prosthesis with a glass-like finish.(b)
Classification. Class II.
