The Science
of Tooth Color

All smiles have something in common, and that is the colors that make up human teeth shades. From A1 to D4, all shades of teeth express a narrow range of red-to-yellow color.

To match every smile, most composite brands require multiple shades. That’s because most composites today depend on the color of red and yellow dyes added to the resin material to emulate tooth shades. This means that dentists must keep a large inventory of different composites to accommodate a variety of patients.

The OMNICHROMA Flow BULK difference

OMNICHROMA Flow BULK is a bulk fill composite that utilizes translucency and structural color to shade match

Structural Color

Structural color occurs when different wavelengths of light are amplified or weakened by the structure of a material itself, expressing colors other than what the material may actually be. From morpho butterflies to peacocks, some of the rarest and most beautiful colors in nature are the result of structural color.

OMNICHROMA filler generate red-to-yellow structural color as ambient light passes through the composite, without the need of added pigments and dyes. The red-to-yellow color combines with the reflected color of the patient’s surrounding dentition, creating the perfect match from A1 to D4 and beyond.

Smart Chromatic

Through the utilization of Tokuyama’s spherical fillers and Smart Chromatic Technology, OMNICHROMA Flow BULK is the first use of structural color in composite dentistry.

OMNICHROMA Flow BULK’s structural color mechanism is made possible by the precise shape and size of the filler within the composite. The 260nm identical spherical fillers of OMNICHROMA are the perfect size and shape to produce the effects of structural color to match the surrounding tooth color.
