Intended Use

els extra low shrinkage® composite & els extra low shrinkage® flow are restorative materials intended for the reconstruction or correction of natural dentition.

Device Story

Light-cured, methacrylate-based resin restorative materials; used by dentists in clinical settings to reconstruct or correct natural dentition. Input: uncured resin paste applied to tooth defects. Transformation: light-curing (400-500 nm) initiates polymerization, hardening the material into a permanent restoration. Output: cured, radiopaque, microhybrid composite filling. Benefits: low shrinkage stress, biocompatible, aesthetic tooth-colored restoration. Healthcare providers use the material to fill cavities, repair fractures, or attach indirect restorations, directly impacting clinical outcomes by restoring tooth function and aesthetics.

Clinical Evidence

No human clinical testing performed. Substantial equivalence supported by bench testing per ISO 4049:2009 (compressive strength, flexural strength, water sorption, solubility, depth of cure, radiopacity) and biocompatibility testing per ISO 10993-1:2018 and ISO 7405:2018.

Technological Characteristics

Light-cured, radiopaque microhybrid composite. Composition: methacrylate-based resins, dental glass-filler, photo initiators, pigments. Curing wavelength: 400-500 nm. Complies with ISO 4049:2009 (Type 1, Class 2, Group 1 & 2 for composite; Type 2, Class 2, Group 1 for flow). Non-sterile.

Indications for Use

Indicated for patients with permanent dentition requiring restoration. els extra low shrinkage® composite is indicated for class I-V cavity restorations, indirect restorations (inlays, onlays, veneers), aesthetic corrections (interdental spaces, enamel hypoplasia, discolorations), and splinting. els extra low shrinkage® flow is indicated for minimally invasive restorations, small cavities, extended fissure sealing, undercut cavities, class III-V restorations (including wedge-shaped defects and cervical caries), repair of fillings/veneers/temporary restorations, first layer for class I/II fillings, interlocking loosened teeth, and adhesive attachment of indirect restorations.

Regulatory Classification

Identification

Tooth shade resin material is a device composed of materials such as bisphenol-A glycidyl methacrylate (Bis-GMA) intended to restore carious lesions or structural defects in teeth.

Dear Nevine Erian:

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"
