Chroma ZR

Aesthetic ceramic coating applied over a baked resistant substructure based on ultra hard zircon and sodium oxide.

The dye (Chroma) provides color intensity.

They are designed to reproduce the color of the patient’s natural teeth and to transmit color ranges, to enhance the color saturation of one or more colors included in a given color group, or to reproduce barely distinguishable features of the coloring of natural teeth, to transmit more intense coloring.
