The device is indicated for use for direct anterior and posterior restorations, cavity base or liner, and repair of porcelain/composite.

Device Story

OMNICHROMA FLOW is a low-viscosity, light-cured, radiopaque composite resin paste supplied in 1.8mL plastic syringes. Used by licensed healthcare professionals in dental clinics for direct anterior and posterior restorations, cavity lining, and repair of porcelain or composite structures. The material is cured extra-orally using a halogen or LED curing-light (400-500 nm). The single-shade composite simplifies restorative procedures by eliminating shade selection. The device is non-sterile and intended for single-patient use. Benefits include ease of handling and clinical versatility in restorative dentistry.

Clinical Evidence

No clinical data. Substantial equivalence is supported by bench testing of physical properties (sensitivity to ambient light, depth of cure, flexural strength, water sorption, solubility, color stability, and radiopacity) in accordance with ISO 4049:2009, alongside biocompatibility testing.

Technological Characteristics

Low-viscosity, light-cured, radiopaque composite resin. Materials: silica-zirconia filler, composite filler, UDMA, and ND monomers. Dimensions: 1.8mL syringe. Energy source: external halogen or LED curing-light (400-500 nm). Non-sterile. Shelf life: 3 years (0-25°C). Conforms to ISO 4049:2009.

Indications for Use

Indicated for direct anterior and posterior dental restorations, cavity base or liner, and repair of porcelain/composite materials. Contraindicated for patients with allergies or hypersensitivity to methacrylic monomers, UV absorbers, or other ingredients.

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.

The device is a low viscosity, light-cured, radiopaque composite resin for use in anterior and posterior restorations for all carious classes. OMNICHROMA FLOW is a single shade material. Direct placement of OMNICHROMA FLOW into a prepared cavity allows for easy handling. OMNICHROMA FLOW is designed to be cured by either a halogen or LED curing-light with a wavelength of 400-500 nm. Be sure to light-cure OMNICHROMA FLOW extra-orally and check the time needed for complete hardening of OMNICHROMA FLOW with your lightcuring unit before performing the bonding procedure. The device is intended for use by licensed healthcare professionals only. The device does not come sterilized and is not intended to be sterilized prior to use. The OMNICHROMA FLOW device contains methacrylic monomers and a UV absorber. The device should not be used on patients who are allergic to or hypersensitive to methacrylic and related monomers, UV absorber, or any of the other ingredients. #### Indications for Use The device is indicated for use for direct anterior and posterior restorations, cavity base or liner, and repair of porcelain/composite. #### Comparison of Technological Characteristics The OMNICHROMA FLOW device has the same basic technological characteristics in terms of design, material, and chemical composition as the predicate device identified above, as each device is a tooth shade resin material that is cured by photo polymerization.
