The 850 MiYO ceramic system was specially developed for characterising lithium disilicate restorations prior to crystallisation firing and is tailored to existing crystallisation cycles. By eliminating the need for additional characterisation firing, 850 MiYO enables the rapid production of highly aesthetic and natural-looking restorations. The high colour stability ensures reliable results, as colours do not fade during firing. The characteristic MiYO light dynamics with diffuse light scattering prevents shadowing, which can occur with conventional stains. 850 MiYO is easy to use, does not run and produces a natural shine after crystallisation firing without additional glaze firing.
