ClinConnect Summary

IPS Empress CAD is a leucite glass-ceramic of the SiO2-Al2-O3-K2O material systems with leucite crystal ranging from 5 to 10 µm in size. The leucite crystals increase the material strength and interferes with crack propagation, while the fracture energy is absorbed by the crystalline phase. The resistance and flexural strength (160 Mpa) is improved by the difference in the coefficient of thermal expansion between the glass phase and the crystalline phase and the cooling process following sintering phase.

CELTRA DUO: is a new generation of glass ceramic material. With the aid of a new manuf...
