Device Facts

• Record ID: K080305
• Device Name: NEXCOMP AND META ETCHANT
• Applicant: Meta Biomed Co., Ltd.
• Product Code: EBF · Dental
• Decision Date: Apr 7, 2008
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 872.3690
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Nexcomp is intended to restore carious lesions or structural defects in teeth. It is indicated for Class I, II, IV, and V restorations, core-buildup to replace missing tooth structure, for splinting and for diastema closure, direct veneers, composite and porcelain repairs. Meta Etchant is intended for use in dentin/enamel etching to prepare the tooth surface for application of a bonding agent.

Device Story

Nexcomp: light-cured hybrid composite restorative material; 75 wt.% filled with ultra-fine filler and 40 nm silica particles; radiopaque; used by dentists for cavity preparations, restorations, and structural repairs; bonds micromechanically and chemically to tooth surfaces and adhesives via air-inhibited layer; supplied in tubes for screw-syringe application. Meta Etchant: thickened, colored phosphoric acid semi-gel; used by dentists to etch dentin/enamel surfaces to facilitate bonding agent, cement, or restorative material adhesion. Both devices are used in clinical dental settings to restore tooth structure and improve restorative material retention.

Clinical Evidence

Bench testing only. Compliance with ISO 4049:2000(E) for polymer-based filling, restorative, and luting materials. No clinical data provided.

Technological Characteristics

Nexcomp: Light-cured hybrid composite, 75 wt.% filled, 40 nm silica particles, radiopaque. Meta Etchant: Phosphoric acid-based thickened semi-gel. Both devices are manual, non-electronic, and non-software based. Nexcomp complies with ISO 4049:2000(E).

Indications for Use

Indicated for patients requiring dental restorations (Class I, II, IV, V, core-buildup, splinting, diastema closure, veneers, repairs) or dentin/enamel etching prior to bonding agent application. No specific age or gender contraindications provided.

Regulatory Classification

Common/Usual Name: Composites, restoratives.

- 1. Proprietary Name: Nexcomp
- II. Registration No .: 9681254
- lll. Compliance with Performance Standards: Nexcomp complies with ISO 4049:2000(E), Polymer-based filling, restorative, and luting materials. Also, followed "Guidance for Industry and FDA Staff; Dental Composite Resin Devices - Premarket Notification [510(k)] Submissions"
- IV. Description of the Device: Nexcomp is a highly filled (75 wt.%), light-cured hybrid composite. The material is radiopaque and indicated for all types of cavity preparations. The hybrid blend has an ultra fine filler and 40 nm silica particles. Nexcomp will be marketed in incisal, body translucent, and body opaque shades which correspond with the Vita shade guide.

Nexcomp bonds micromechanically and chemically to prepared tooth surfaces, dental primers and bonding resin adhesives through copolymerization of its air-inhibited layer. It's color can be matched with various shades of standard color quides. It is available in tubes which are designed to be fitted into a screw-syringe with a body cap seal.

- V. Labels and Labeling: Draft labels of Nexcomp and instructions for use are provided, together with warnings and contra-indications.
- VI. Substantial Equivalence: These devices are equivalent to devices manufactured and sold before 1976, having a U. S. classification number (code) EBF, and those described under 21 CFR 872.3690. Each is also equivalent to several devices currently on the market that have been cleared by the premarket notification-510(k) process. Some of these are outlined below:

Dear Mr. 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. 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 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 requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97).
