Pressing tablets with low translucency. For the fabrication of crowns, partial crowns, and three-unit bridges up to the second premolar. Made of lithium silicate ceramic reinforced with zirconium dioxide (ZLS). Advantages: chameleon effect for excellent optical adaptation in vivo, perfect balance between translucency and opalescence, natural opalescence to prevent a grayish hue in the mouth, high flexural strength of over 500 N/mm² for reliable results, excellent edge quality: greater safety in complicated cases, very good flowability through small ZLS microcrystals.
