GC Initial ™ Spectrum Stains shades and glazes were developed for the external characterisation and glaze of tooth-coloured ceramic materials and for the internal individualisation of layering ceramics. The Initial ™ Spectrum Stains are compatible with a wide range of CTE and are therefore perfect for almost all dental ceramics. They go particularly well with the aesthetic colour concept of the Initial ceramic line. The Initial ™ Spectrum Stains are powder shades in 16 different shades that aesthetically enhance your restorations.
