Intended Use
Dental Lithium Disilicate Glass-Ceramic is available using CAD/CAM and hot pressing techniques for the preparation of full ceramic crowns, inlays, onlays, veneer and full ceramic 3-unit anterior bridges.
Device Description
Dental Lithium Disilicate Glass-Ceramic is a lithium disilicate ceramic to be supplied in the form of cuboid and cylinder. Dental Lithium Disilicate Glass-Ceramic can be fabricated using CAD/CAM and hot pressing technologies. The device is a glass type material used for aesthetic purposes of full ceramic crowns, inlays, onlays, veneer and full ceramic 3-unit anterior bridges. The ceramics material is composed of SiO2, Li2O, K2O, Al2O3, P2O5, ZrO2 and other oxides. It contains inorganic pigments. The inorganic pigments generate the color on the restorations, after sintering at dental labs, that matches natural color of patient's teeth. The performance of the device conforms to ISO 6872:2015 Dentistry: Ceramic Materials. It is a single-use device, and provided non-sterile.
More Information

No
The device description focuses on the material composition and fabrication techniques (CAD/CAM, hot pressing) of a dental ceramic. There is no mention of AI, ML, image processing, or any software-driven analytical capabilities. The performance studies are bench tests evaluating material properties and biocompatibility against standards.

No.
The device is a material used for dental restorations (full ceramic crowns, inlays, onlays, veneer, bridges) that replace missing or damaged tooth structure for aesthetic and functional purposes, rather than directly treating a disease or condition.

No

Explanation: The device is a material used for manufacturing dental restorations like crowns and veneers. It is a fabricated product, not a tool or system designed to identify or analyze medical conditions or diseases.

No

The device description clearly states it is a physical material (lithium disilicate ceramic in cuboid and cylinder form) used for dental restorations, not a software program.

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

Here's why:

  • Intended Use: The intended use is for the preparation of dental restorations (crowns, inlays, onlays, veneers, bridges) using CAD/CAM and hot pressing techniques. This is a manufacturing process for a medical device that will be placed in the patient's mouth.
  • Device Description: The device is a material (glass-ceramic) used for aesthetic and functional purposes in dental restorations. It is a physical material that is shaped and processed to create a final device.
  • Lack of Diagnostic Purpose: There is no mention of this device being used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. IVDs are typically used to test blood, urine, tissue, or other bodily fluids or samples.

This device is a dental material used in the fabrication of dental prosthetics, which are considered medical devices, but not IVDs.
