MIRIS2 offers a unique shade system on the basis of the natural layering concept, which works with dentin and enamel masses whose optical properties are comparable with those of the original tissue. For this purpose, the shades and translucency of natural teeth in adolescent, adult and elderly patients were measured and emulated. For achieving an aesthetically optimal definition of shade, the MIRIS2 Shade Guide is separated into composite-based dentin cores and enamel shells that can be freely interposed on one another. Shade S1. Contains 1pc 4g syringe.
