KERADEC is a fuse-on gold paste used by dental technicians to manufacture and gold-coat dental appliances, primarily for aesthetic and material optimization purposes. It is explicitly described as being used to "fabricate dental appliances," "gold coating," "improves the color reproduction," and "optimizes the color of white dental alloys," which are not therapeutic functions.
No
Explanation: KERADEC is a fuse-on gold paste used by dental technicians to fabricate dental appliances. Its function is to coat metal surfaces, improve color reproduction, and reduce oxidation, not to diagnose medical conditions or provide diagnostic information.
No
The device is a physical gold paste used in the manufacturing of dental appliances, not a software program.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that KERADEC is used by dental technicians to manufacture dental appliances for patients. This involves fabricating physical devices that are placed in the mouth.
- Device Description: The description details the composition and application of a gold paste used for coating dental alloys. It describes a material used in the creation of a medical device (dental appliance), not a test performed on biological samples to diagnose or monitor a condition.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Providing information for diagnosis, monitoring, or screening of diseases or conditions
- Using reagents or kits for testing
Instead, the description aligns with a material used in the manufacturing process of a medical device (dental prosthesis). The mention of meeting the essential requirements of the European directive 93/42/ECC concerning medical devices further supports its classification as a medical device component, not an IVD.

Intended Use / Indications for Use
KERADEC is a fuse-on gold paste, which can be used by dental technicians to manufacture dental appliances for patients.
It is intended for gold coating of white metal surfaces in cervical areas, elimination of casting cavities, gold coating of occlusal surfaces and inlay imitations.
In addition, it can be used within the AGC electroforming technique to manufacture AGC Bridges with the sintering procedure.

Device Description
KERADEC is a fuse-on gold paste, which can be used by dental technicians to fabricate dental appliances for patients. It consists of spherical gold particles and an organic liquid.
KERADEC is intended for gold coating of white dental alloys. It can be used for gold coating of white metal surfaces in cervical areas, elimination of casting cavities, gold coating of occlusal surface and inlay imitations.
The use of KERADEC improves the color reproduction of ceramics on white porcelainfused-to-metal alloys. It optimizes the color of white dental alloys and reduces oxidation of these alloys. It does not improve the metal to ceramic bond.
For applying, KERADEC has to be brushed onto the surface of the alloy and, after drying, it has to be fired in a ceramic furnace (820°C). In the course of these heat treatments, the organic liquid will completely vaporize and the gold will form a very thin layer of pure gold (99.99%), which is partly diffused into the surface of the alloy.
KERADEC is highly corrosion resistant. It meats the essential requirements of the European directive 93/42/ECC concerning medical devices.

Dear Dr. Polzer:
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. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting vour device can be found in the Code of Federal Regulations. Title 21. Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
