The device description details a chemical composition for a dental relining material and does not mention any software, algorithms, or data processing capabilities indicative of AI/ML.
Yes.
The device is used for conditioning soft tissue distorted or damaged by ill-fitting dentures and as a temporary lining for comfort after tooth extraction or oral surgery, indicating a therapeutic purpose.
No
This device is a tissue conditioner and temporary liner for removable dentures, intended for therapeutic use (conditioning soft tissue, making dentures more comfortable), not for diagnosing a condition or disease.
No
The device description clearly outlines physical components (powder, liquid, adhesive) that form a resin material kit, indicating it is a physical medical device, 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 conditioning soft tissue in the mouth and as a temporary lining for dentures. This is a direct application to the patient's oral cavity for therapeutic and comfort purposes.
- Device Description: The components are materials used to create a physical liner for dentures.
- Lack of Diagnostic Function: There is no mention of the device being used to test samples from the human body (like blood, urine, tissue, etc.) to provide information about a physiological state, health, disease, or congenital abnormality.
IVD devices are specifically designed to perform tests in vitro (outside the body) on biological specimens to aid in diagnosis or monitoring. This device is used in vivo (within the body) as a temporary therapeutic and comfort aid.

Device Description
The main components of the TOKUYAMA TISSUECARE kit are:
- (1) powder (containing polyalkyl methacrylate and amorphous silica filler):
- (2) liquid (containing polvalkyl acrylate plasticizer and ethanol); and
- (3) adhesive (containing polyalkyl methacrylate and ethyl acetate).
The liner is formed by combining the powder and the liquid. The adhesive is used to bond the acrylic surface (it cannot be used to bond nylon, metal, or silicone surfaces). The TOKUYAMA TISSUECARE device utilizes a plasticizer that allows for continuous malleability and almost no surface roughness of the lining material when used in the short term.

Intended Use
The TOKUYAMA TISSUECARE denture relining, repairing, or rebasing resin material kit is a tissue conditioner and temporary liner for removable dentures. It is a prescription device intended for short-term use for conditioning of soft tissue distorted or damaged by the wearing of ill-fitting dentures, and for use as a temporary lining to make existing dentures more comfortable immediately after tooth extraction or oral surgery.
Technological Characteristics and Substantial Equivalence
The main components of the TOKUYAMA TISSUECARE kit are:
- (1) powder (containing polyalkyl methacrylate and amorphous silica filler):
- (2) liquid (containing polvalkyl acrylate plasticizer and ethanol); and
- (3) adhesive (containing polyalkyl methacrylate and ethyl acetate).
The liner is formed by combining the powder and the liquid. The adhesive is used to bond the acrylic surface (it cannot be used to bond nylon, metal, or silicone surfaces). The TOKUYAMA TISSUECARE device utilizes a plasticizer that allows for continuous malleability and almost no surface roughness of the lining material when used in the short term.
The TOKUYAMA TISSUECARE denture relining, repairing, or rebasing resin material kit is substantially equivalent to several predicate devices, including Austenal's "Myerson's Permasoft Soft Reline Material" (K#933468).
Although the TOKUYAMA TISSUECARE denture relining, repairing, or rebasing resin material kit may have slightly different performance characteristics than the predicate devices, these differences do not raise new questions of safety or effectiveness. The efficacy of the device has been shown to be substantially equivalent pursuant to ISO10139-1:1991, and all ingredients used in the TOKUYAMA TISSUECARE denture relining, repairing, or rebasing resin material kit are biocompatible.
