No
The document describes a physical dental material and its properties, with no mention of software, algorithms, or AI/ML concepts.
No
This device is a denture relining, repairing, or rebasing resin, which functions to repair or reline dentures, not to provide therapy for a medical condition.
No
The device is described as a denture relining, repairing, or rebasing resin and a soft lining material for removable dentures. Its function is to modify dentures, not to diagnose a condition or disease.
No
The device description clearly outlines physical components such as paste, primer, spatula, brush, etc., and describes testing of physical properties, indicating it is a physical material device, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "as a denture reliner." This is a direct application to a medical device (a denture) for a physical purpose (relining).
- Device Description: The description confirms it's a "chairside soft lining material for removable dentures." It's a material used to modify a medical device.
- Lack of Diagnostic Purpose: There is no mention of the device being used to test samples from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
IVD devices are specifically designed to perform tests on biological samples to provide diagnostic information. This device is a material used in the repair and modification of a medical device (a denture).

Device Description
The SOFRELINER TOUGH S denture relining, repairing, or rebasing resin device is a prescription addition-cured silicone chairside soft lining material for removable dentures. It is indicated for use as a denture reliner.
The main components of the SOFRELINER TOUGH S device are:
-
- A paste consisting of a base and catalyst;
- A primer packaged separate used for bonding to the acrylic surfaces; and 2)
- Various accessories, namely a spatula, brush, drip-cap, drip-cup, mixing 3) tip, coarse point, finish wheel, and washer
Nearly all ingredients used in the SOFRELINER TOUGH S denture relining, repairing, or rebasing device are either commonly used in similar dental devices or have been subjected to extensive biocompatibility testing. However, the paste of the SOFRELINER TOUGH S does contain one new ingredient and thus toxicity testing was performed, namely cytotoxicity, sensitization, irritation, subchronic systemic toxicity, and genotoxicity.
The SOFRELINER TOUGH S denture relining, repairing, or rebasing resin device does not come sterilized and is not intended to be sterilized prior to use.
