Cerpress SL is a great choice for lab technicians that are seeking esthetics, value and performance from a pressable ceramic system. Fewer problems have been reported than with other systems because of the low firing temperature of the Sensation overlay porcelain. The Cerpress ingots are fused so it is easy to see the shade before pressing and they require no preheating. Available in 4 different levels of opacity: translucent (T), medium opacity (M), high opacity (H), or regular. This is a high opacity, HB0 ingot. It is used when the requirement for the restoration is extreme opacity. Like the medium opacity ingots, they are used mostly for anterior restorations, where a core is pressed and built up with Sensation Porcelain. When making a restoration that is built up on a core, it is recommended to press it 1 shade lighter than what is desired. 5 ingots per package. Made in Liechtenstein.
