Indications for Use

Crown, Bridges, Veneer, Onlay & Inlay, Denture, partial denture, Orthodontic appliance, Splints. - Characterization of direct and indirect composite restorations, acrylic denture base and artificial acrylic teeth. - For obtaining surface smoothness and wear resistance of restorations made of composite resin, acrylic denture base and artificial acrylic teeth.

Device Story

ID Light Cure System is a light-curing, resin-based coating material for dental restorations and prosthetic appliances. The material is applied to the surface of dental restorations (e.g., crowns, bridges, dentures) to enhance surface smoothness and wear resistance. The system is available in 51 shades. The device is used by dental professionals in a clinical setting. The principle of operation involves applying the resin-based coating to the restoration surface, followed by photopolymerization using a light source of a specific wavelength to cure the layer. This process creates a protective film that improves the durability and aesthetic characterization of the dental work. The device benefits the patient by increasing the longevity and surface quality of their dental restorations.

Clinical Evidence

Bench testing only. Biological safety testing included cytotoxicity, skin sensitization, oral mucosa irritation, and acute systemic toxicity per ISO 10993-1:2018 and ISO 7405:2018. Performance testing evaluated appearance, weight, packaging integrity, color stability, sensitivity to ambient light, and depth of cure. All tests met internal protocols and performance specifications.

Technological Characteristics

Resin-based coating material; photopolymerization curing mechanism; requires external light source of specific wavelength; available in 51 shades; biocompatibility testing per ISO 10993-1:2018 and ISO 7405:2018.

Indications for Use

Indicated for dental patients requiring surface coating of crowns, bridges, veneers, onlays, inlays, dentures, partial dentures, orthodontic appliances, and splints to improve smoothness and wear resistance, and for characterization of composite restorations and acrylic denture components.

Regulatory Classification

Identification

A coating material for resin fillings is a device intended to be applied to the surface of a restorative resin dental filling to attain a smooth, glaze-like finish on the surface of the filling.

Dear Eunhui Lim:

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 (the 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 available 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

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

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Upon evaluating the biological safety of the "ID LIGHT CURE SYSTEM (Model Name: CROWN FLOW A1 and 50 others)" it is considered that this product does not contain any added substances that specifically induce toxicity or have significantly different elements or mixing ratios compared to the predicate named "OPTIGLAZE COLOR" on the market. Furthermore, no significant differences in intended use or mechanism of action were found when compared to the predicate device. Cytotoxicity, skin sensitization, oral mucosa irritation, and acute systemic toxicity endpoint testing were performed for the subject device in accordance with ISO 10993-1:2018 and ISO 7405:2018.

Evaluation of the biological safety test reports for the "ID LIGHT CURE SYSTEM (Model: GUM FLOW BLACK)" showed no observed cytotoxic reactions, no oral mucosal irritation or skin sensitization reactions, and no systemic toxic reactions. Regarding additional biological safety tests for the "ID LIGHT CURE SYSTEM (Model Name: CROWN FLOW A1 and 50 others)," sufficient data on toxicity and benefits can be observed through the review of literature with long-term use experience.

A series of performance tests were conducted to evaluate the physical properties of the device, including appearance, weight, packaging integrity, color stability, sensitivity to ambient light, and depth of cure. All tests were performed in accordance with internal protocols and relevant standards. The device successfully passed all evaluations, demonstrating acceptable physical characteristics and confirming that the product meets its intended technical and performance specifications.

In conclusion, when the "ID LIGHT CURE SYSTEM (Model Name: CROWN FLOW A1 and 50 others)" is used according to the intended purpose and method of use provided by the manufacturer, the device is substantially equivalent to the predicate device.
