No.
A therapeutic device is one that treats a disease or condition. This device is a bonding agent used in the fabrication or repair of removable dentures, which are prosthetic devices, not therapeutic ones.
No
The device is a bonding agent used in the fabrication and repair of removable dentures, which is a therapeutic or restorative function, not a diagnostic one.
No
The device is a bonding agent, which is a physical substance used to fix prosthetic teeth. The description focuses on its material properties and performance in physical tests, not software functionality.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "fix custom-fit prosthetic teeth in appropriately milled cavities of prosthetic bases." This is a mechanical function for fabricating a dental prosthesis.
- Device Description: The device is a "single-component self-cure bonding agent intended for use with milled PMMA denture base resins and milled PMMA denture teeth." It's used in the "fabrication or repair of removable dentures."
- Lack of Diagnostic Purpose: There is no mention of the device being used to diagnose, monitor, or treat a disease or condition by examining specimens from the human body. IVDs are typically used to analyze blood, urine, tissue, or other bodily fluids.
The device is clearly intended for use in the manufacturing and repair of dental prostheses, which falls under the category of dental devices, not in vitro diagnostics.

Dear Prithul Bom:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

Product Code/Device/Regulation/Regulation/Intended Use/Technology/Biocompatible/ Rx/Sterility - The Subject and Predicate devices are the same.
How Supplied - The Subject and Predicate devices are similar as they are both liquids supplied in bottles. The Subject device is delivered in a single bottle, the Predicate device is two liquids supplied in separate bottles. The Subject device does not require mixing of liquids to accomplish the self-curing bonding process. The Predicate device requires mixing of two different liquids to create a compound that will result in a self-curing bonding agent. The number of bottles and need to mix does not change the intended use of the device to Fix custom-fit prosthetic teeth in appropriately milled cavities of prosthetic bases. The Subject device has demonstrated suitability for intended use through material non-clinical performance testing.
Principle of Operation - The Subject and Predicate devices are the same in that they are both self-curing agents when applied to acrylic resin. However, the Subject device creates a self-cure chemical bond with a single liquid applied between the custom fit prosthetic teeth and milled prosthetic base. The Predicate device requires mixing of two different liquids to create a compound that results in a self-curing bonding agent. The number of liquids and a requirement to mix liquids prior to application does not change the intended use of the devices. Differences in usage technique are mitigated through performance testing. The Subject device has demonstrated suitability for intended use through material non-clinical performance testing including comparative testing with the Predicate device.
Performance Testing – The Subject and Predicate devices were tested by their respective sponsors to the same ISO 20795-1 material property standard, meeting the relevant requirements of the standard which could be applied to a liquid such as the Subject device. Additionally, comparative tensile strength testing was performed with the Subject and Predicate devices and demonstrated similar performance.
Biocompatibility - The Subject and Predicate devices were tested to the same biological testing endpoints.
Overall, the Technological Characteristics of the Subject and Predicate devices are the Same or Similar. Technological differences between the Subject and Predicate devices have been evaluated through non-clinical performance testing. The results of the tests performed show that Subject device meets the requirements mentioned in the applicable standards and confirm that the Subject device performs similarly to the Predicate device based on the requirements of the standards.
CLINICAL AND ANIMAL TESTING
No clinical or animal testing data is included in this submission.
NON-CLINICAL PERFORMANCE TESTING
Physical property testing was performed on the Subject device to ISO 20795-1, Dentistry — Part 1: Denture base polymers. Results demonstrated the Subject device meets the property requirements of the referenced standards for the endpoints which could be applied to self-curing bonding agents for denture base polymers such as the Subject device. Comparative tensile strength testing was performed with the Subject and Predicate devices and demonstrated similar performance between the Subject and Predicate devices. Shelf-life testing was performed to support the shelf-life stated in device labeling.
A biological evaluation was performed on the Subject device. An abbreviated chemical characterization was performed along with a Toxicological Risk Assessment. Biocompatibility testing was performed on the Subject device according to ISO 10993-1:2018 according to the standards listed in the Technological Characteristics comparison table above.
An MRI safety assessment was performed on the Subject device to support MR Safety labeling as required by the FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment".

Non-clinical performance testing of the Subject device met the acceptance criteria for each validation and test described above. This non-clinical performance testing demonstrates that the Subject device is suitable for intended use.
CONCLUSION
Overall, the Indications for Use statements for the Subject and Predicate devices are highly similar differing only in device name. Overall, the Technological Characteristics of the Subject device are the same or similar to the Predicate device with any differences mitigated through non-clinical performance testing.
Overall, these similarities between the Subject and Predicate devices support a determination of substantial equivalence.
