The device description and performance studies focus on the material properties and biocompatibility of a silicone-based denture liner, with no mention of AI or ML technologies.
No
Explanation: A therapeutic device is designed to treat or alleviate a medical condition. While this device aims to reduce sore spots and improve comfort for denture wearers, it primarily functions as a long-term soft lining material to improve the fit of dentures, rather than treating a disease or injury.
No
Explanation: The device description clearly states its purpose is to provide a "cushion between the denture and the mouth tissues to aid in reducing sore spots, and allows improved adaptation to tissue contours thereby aiding in a comfortable fit of the denture." This indicates a therapeutic or palliative function, not a diagnostic one. Diagnostic devices are used to identify or determine the presence of a disease or condition.
No
The device description clearly states it is a "silicone-based soft lining material" and mentions physical properties like hardness and bond strength, indicating it is a physical material, 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 "as a long-term soft liner for removable dentures." This describes a material used in the mouth to improve the fit and comfort of a denture, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The description details a silicone-based material for lining dentures, focusing on its physical properties and how it functions within the mouth. It doesn't mention any components or processes related to analyzing biological samples.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring specific analytes
- Providing diagnostic information about a disease or condition
The ComfortSoft® Soft Denture Liner System is a medical device, but it falls under a different category than IVDs. It's a material used to modify and improve the function of a prosthetic device (the denture) within the body.

5. PREDICATE DEVICE COMPARISON
ComfortSoft Soft Denture Liner System is substantially equivalent to Luci-Sof (trubyte) made by Dentsply (K964040). The Indications For Use for both devices state they are intended as a long term soft liner for removable dentures and are Shore A type material. Both are of a silicone type material and use and initiator/bonder. Both require a 2mm minimum denture base thickness. Luci-Sof has passed biocompatibility testing, but information is not available in comparison to ComfortSoft Soft Denture Liner. ComforSoft Soft Denture Liner passed biocompatibility tests for MEM elution, Guinea Pig Maximization Sensitization, Intracutaneous Toxicity, Systemic Toxicity, Sub-Acute Toxicity, Ames test, Chromosomal Aberration, and In vivo Mouse Micronucleus Extract. ComfortSoft soft Denture liner also has a bond strength of at least 1MPa whereas Luci-Sof claims a 15.3 kN/m²,
