No
The description details a self-curing acrylic resin and its components, with no mention of AI or ML capabilities. The performance studies focus on material properties and equivalence to predicate devices, not algorithmic performance.
No.
The device is an acrylic resin used for dental applications like temporary fillings, crowns, and bridges, as well as denture repair and adjustments. It does not directly provide therapy for a disease or condition but rather serves as a material for dental restorations.
No
Explanation: The device is an acrylic resin used for dental repairs and temporary applications, not for diagnosing medical conditions. Its intended use focuses on treatment and restoration, not diagnosis.
No
The device description clearly states it is a self-curing acrylic dental resin composed of powder and liquid, which are physical components, not software.
Based on the provided information, the TOKUYAMA CUREGRACE device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended uses listed are all related to dental applications within the mouth (temporary restorations, denture repair, etc.). These are applications directly on or within the patient's body, not for testing samples taken from the body.
- Device Description: The description details a material used for physical dental restorations and repairs. It doesn't mention any components or functions related to analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of the device being used to diagnose, monitor, or screen for diseases or conditions by examining samples like blood, urine, tissue, etc.
IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for diagnosis, monitoring, or screening. The TOKUYAMA CUREGRACE device's function is purely restorative and structural within the dental context.

Device Description
The TOKUYAMA CUREGRACE device is a self-curing acrylic dental resin used for relining, repairing, and rebasing and for temporary crowns and bridges. The device is composed of a powder and liquid that is cured by chemical polymerization. The powder is packaged in a plastic bottle, and the liquid is packaged in a glass bottle.
The powder comes in four shades designated as A2, A3, Pink, and Live Pink.
The device does not come sterile and is not intended to be sterilized prior to use.
The TOKUYAMA CUREGRACE device comes with a measuring cup for measuring the powder component and a dropper for dispensing the liquid component. The measuring cup is made from standard polypropylene, and the material has been used for the measuring cup of Tokuyama's own "Tokuyama Rebase II" device (K#022641). The dropper is made from standard polyethylene or ethylene-vinylacetate copolymer. The polyethylene has been used for the dropper of the "Tokuyama Rebase II" device and the ethylene-vinylacetate copper or has been used for the dropper of Tokuyama's own "Tokuso Curefast" device authorized in Japan since 1998.
