The Science of Tooth Color
OMNICHROMA Sub-Micro-Pearl-Technology
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.
OMNICHROMA comes from the TOKUYAMA
Research Center in Japan.
The TOKUYAMA DENTAL Corporation, based in Japan, has been developing innovative dental solutions for over 40 years and is one of the leading manufacturers of products for conservative and prosthetic dentistry.
The OMNICHROMA difference.
The secret is our method of manufacture
Glass materials are ground until the individual particles of the fillers lie approximately within a desired size range. However, the fillers clearly differ in shape and size.
TOKUYAMA DENTAL produces OMNICHROMA fillers based on its own patented “Sub-Micro-Pearl-Technology”. In this process, the Sol-Gel method is used to progressively coat spherical fillers in an organic solution. After several weeks, the fillers have “grown” evenly in a spherical shape and are exactly in size. In this optimal size, the desired colour adaptation effect is achieved precisely in combination with other outstanding physical properties.

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