Brief Summary:
The most frequent reason for failure of laminate veneers made of glass ceramics feldspathic leucite based and lithium silicate based ceramics was fracture of the ceramic Therefore ceramic materials that have higher fracture resistance especially for patients suffering from abnormal occlusion are needed
Detailed Description:
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 manufacturing process the glass ceramic is infiltrated with 10 zirconia by weight producing zirconia reinforced lithium silicate ceramic ZLS The material is characterized by a unique homogenous structure with fine grains that provides excellent material quality and consistency high strength properties and long term performance In addition the material offers satisfying processing characteristics which can be milled and polished easily After milling the restorations are shaded correctly shaded with no need for crystallization step 10 The milled restorations have a flexural strength of 210 MPa After stain and glaze firing the restoration will exhibit a flexural strength up to 370 MPa
