OMNICHROMA

One-Shade Universal Composite
Every Shade, One Choice

OMNICHROMA by Tokuyama Dental is a light-curing, radiopaque composite that offers the ultimate in colour matching. It can cover all 16 VITA classical shades with only one colour. For the first time, colours are not created by the addition of pigments, but rather by deliberately induced structural colours combining with the reflected colour of the surrounding tooth. The OMNICHROMA phenomenon uses the Smart Chromatic Technology along with the spherical fillers (260nm spherical SiO2-ZrO2) from TOKUYAMA, which are manufactured according to the “cultured pearl principle”. The effect: A single composite for all colours. Uniquely natural and aesthetic. Uniquely smooth and shiny. Uniquely simple and time saving.

* OMNICHROMA matches every tooth shade with a single shade of composite, as demonstrated above.

Procedure

OMNICHROMA offers a single shade of composite that matches every tooth from A1 to D4 and beyond.

OMNICHROMA follows a standard, easy-to-use procedure for most cases. While opaque-white before curing, OMNICHROMA becomes natural in appearance and matches the color of the surrounding tooth after light curing.

For Large Anterior Cases:

For use with large and extensive anterior cases, Tokuyama offers OMNICHROMA BLOCKER, a supplementary material to be used in conjunction with OMNICHROMA for the direct restoration of extensive Class III and IV cavities.

OMNICHROMA BLOCKER can be used as a lingual layer to prevent shade-matching interference in these cases. OMNICHROMA BLOCKER can also be used to mask slight staining, or to reconstruct a highly opaque tooth.

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.
