OMNICHROMA Fillers & Structural Color
OMNICHROMA exhibits the ultimate wide-range color-matching ability, covering all VITA classical shades with just one shade of composite, thanks to Tokuyama’s Smart Chromatic Technology. The Smart Chromatic Technology is achieved by Tokuyama’s uniformly sized 260nm spherical fillers included in OMNICHROMA.
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. The Munsell Sphere below demonstrates the color range of teeth.
For decades, restorative dentistry has relied on composites that require multiple shades to match the esthetic needs of patients. That’s because most composites today are comprised of red and yellow dyes or pigments added to the resin material to emulate tooth shades. The shade-matching ability of most composites is limited, necessitating a large inventory of composite shades to accommodate a variety of patients.
OMNICHROMA Mechanism 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 utilizes structural color with its 260nm spherical fillers. The fillers are the exact size and shape needed to generate red-to-yellow color as ambient light passes through the composite, without the need of added pigments or dyes. This red-to-yellow color generated by the spherical fillers combines with the reflected color of the patient’s surrounding dentition, creating the perfect match from A1 to D4 and beyond.
Combine this unprecedented shade-matching ability with the exceptional handling, polishability, and strength made possible by TOKUYAMA’s spherical fillers, and OMNICHROMA is truly the next generation of universal composites.
