Intended Use
The Obsidian™ Milling Blocks is used to fabricate ceramic dental prostheses in the nature of crowns and bridges for posterior and anterior applications using CAD/CAM methods.
Device Description
The Obsidian™ Milling Blocks are a lithium silicate ceramic to be supplied with or without an attached mandrel to be milled using CAD/CAM methods. The product can produce a variety of monolithic restorations with great esthetics, lifelike translucency, and high strength including full-contour crowns, inlays, onlays, veneers partial crowns and substructures due to its excellent machining properties. The milling blocks will be available in the commonly used VITA Classical and Chromascop Bleach shades.
More Information

Not Found

No
The summary describes a ceramic material for dental prostheses and its physical properties, with no mention of AI or ML in its function or manufacturing process.

No.
The device is used to fabricate dental prostheses, which are replacements for missing or damaged teeth, rather than directly treating a medical condition or disease.

No

The device is described as ceramic milling blocks used to fabricate dental prostheses (crowns and bridges), not to diagnose a disease or condition. Its performance metrics relate to material properties (e.g., strength, solubility), not diagnostic accuracy.

No

The device description clearly states it is a lithium silicate ceramic block, which is a physical material, not software. The summary focuses on the material properties and performance of the block itself.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples such as blood, urine, or tissue that have been taken from the human body to detect diseases or other conditions. They are used to provide information for diagnosis, monitoring, or screening.
  • Obsidian™ Milling Blocks Function: The Obsidian™ Milling Blocks are used to fabricate dental prostheses (crowns and bridges). This is a manufacturing process for a medical device that will be placed in the body, not a test performed on a sample from the body to diagnose or monitor a condition.
  • Intended Use: The intended use clearly states the fabrication of dental prostheses using CAD/CAM methods. There is no mention of analyzing biological samples or providing diagnostic information.
  • Device Description: The description focuses on the material properties and how it is used to create dental restorations.
  • Performance Studies and Key Metrics: The performance studies and key metrics relate to the physical and chemical properties of the material and its biocompatibility, which are relevant for a dental restorative material, not an IVD.

Therefore, based on the provided information, the Obsidian™ Milling Blocks are a dental restorative material used in the fabrication of dental prostheses, not an in vitro diagnostic device.

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

To meet the ISO 6872 requirements, various non-clinical and applicable tests were performed in accordance with the Design Verification Plan including a Risk Analysis addressing the impact of changes to the device. The test results for the Flexural Strength, Chemical Solubility, Freedom from Extraneous Material, Radioactivity, and Coefficient Thermal Expansion indicate the Obsidian™ Milling Blocks is comparable to the predicate device.
In addition, the proposed device, Obsidian™ Milling Blocks, have been tested for Cytotoxicity (ISO 10993-5), Sensitization (ISO 10993-10), and Irritation (ISO 10993-10) to meet the biocompatibility requirement and the reports are as follow:

  • The Cytotoxicity Report shows that there was no reaction on any of the cells.
  • The Sensitization Report shows that there was no reaction on the tested subject.
  • The Irritation Report shows that there was no erythema or edema on the test subject.

Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

Flexural Strength: >300 MPa (meeting ISO 6872 requirements)
Chemical Solubility:

§ 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.

Dear Mr. Zehtabchi:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
