Intended Use

Perfit CL can be used as an accessory to zirconium dioxide dental restorative material to provide individual tooth (or teeth) shading. It is intended to be used solely by certified dental technicians for fabrication of zirconium dioxide restorations for individual dental patients.

Device Story

Perfit CL is a water-based coloring liquid containing inorganic pigments used to shade pre-sintered zirconium dioxide dental restorations. Used by certified dental technicians in a laboratory setting; the liquid is applied to the zirconia body via brush or immersion prior to the sintering process. The coloring process allows the final restoration to match the shade of natural teeth. The device is non-sterile and supplied in liquid containers. It benefits the patient by providing aesthetic, tooth-colored dental restorations.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing, including shelf-life, biocompatibility (ISO 10993-3, -5, -10, -11), and performance testing (ISO 6872, appearance, volume, packaging, dissolution, color stability).

Technological Characteristics

Water-based liquid containing inorganic pigments. pH 5.5-8.0; boiling point 100°C; density 1.00-1.10 g/cm3; 100% water soluble. Non-sterile. Tested to ISO 10993 (biocompatibility) and ISO 6872 (dental ceramic standards).

Indications for Use

Indicated for use as an accessory to zirconium dioxide dental restorative material to provide individual tooth shading. Intended for use by certified dental technicians for fabrication of zirconium dioxide restorations for individual dental patients.

Regulatory Classification

Identification

Porcelain powder for clinical use is a device consisting of a mixture of kaolin, felspar, quartz, or other substances intended for use in the production of artificial teeth in fixed or removable dentures, of jacket crowns, facings, and veneers. The device is used in prosthetic dentistry by heating the powder mixture to a high temperature in an oven to produce a hard prosthesis with a glass-like finish.

Dear Dave Kim:

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your 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. You must comply with all the Act's

{1}------------------------------------------------

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

{6}------------------------------------------------

The subject device is substantially equivalent to the predicate device, DMAX coloring liquid, Chang's liquid, Confident coloring liquid, CAMeleon coloring liquid, (K173769) made by DMAX Co., Ltd. Both the device has the same indications for Use and technological characteristics. They even have the same pH, boiling point, density and specific gravity range. Both devices are soluble in water. The raw material composition rate might be different between the devices, however, the subject device meets the requirements ISO 10993, therefore, this difference would not raise a question in substantial equivalence.

| 5.9 | Conclusion | Based on the testing results, Vatech mcis Co., Ltd concludes that the<br>subject device is substantially equivalent to the predicate device. |
