The device description and performance studies focus on the material composition and biocompatibility of a dental stain, with no mention of AI/ML or related technologies.
No.
The device is a stain material for color characterization of dental restorations, not a therapeutic agent that treats or prevents disease.
No
The device is a stain material used for color characterization during the laboratory fabrication of dental restorations (jacket crowns, facing crowns, inlays, and onlays), not for diagnosing conditions.
No
The device description explicitly states it is composed of materials like dimethacrylate monomers and inorganic fillers, which are physical components, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "Color characterization for: 1) Jacket crown, 2) Facing crown, 3) Inlay and onlay." This describes a material used in the fabrication of dental restorations, not a test performed on a biological sample to diagnose a condition.
- Device Description: The description clearly states it's a "tooth shade resin material" used for "laboratory fabrication of jacket crown, facing crown, inlay and onlay restorations." It's a material for creating a physical product.
- Lack of Diagnostic Purpose: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing information for the diagnosis, treatment, or prevention of disease.
- Focus on Material Properties: The performance studies focus on the biocompatibility and toxicity of the materials used in the stain, which is relevant for a dental material but not for an IVD.
IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens derived from the human body to provide information for diagnostic purposes. This device is a material used in vitro to create a dental restoration, which is then placed in vivo (in the body).

In general, resin-based crown and bridge materials consists of body resin such as transparent, enamel and dentin, opaque resin, stain and accessories. CHROMA ZONE COLOR STAIN is a stain material for color characterization to be used in conjunction with resin-based crown and bridge materials. CHROMA ZONE COLOR STAIN is substantially equivalent in intended use and performance to that of products sold in the U.S. market. There are two methods for color characterization. One method is to put a stain material to dentin resin and place enamel resin on it.(Inner stain technique) The other method is to put a stain material to pit and fissure site after shaping and polishing (Surface stain technique) CHROMA ZONE COLOR STAIN is used by these methods and the procedure is same to that of products sold in the U.S. market.
CHROMA ZONE COLOR STAIN is substantially equivalent in design, components and function to that of products sold in the U.S. market.
