Ceramic dental material HT

zirconiumfor dental inlaysfor dental veneers

Super translucent material is intended for the manufacture of veneers, inlays, onlays, monolithic crowns for frontal restorations, crowns for abutments, bridges up to 3 units. The translucency of the material is comparable to the translucency of lithium disilicate. Blanks are presented in white and pre-shade in 16 shades according to the VITA® Material Characteristics Translucency - 49% ISO 6872:2015 Classification - Type II class 5 Thermal expansion coefficient, 10-6 К-1 - 9,9±0,2 Crack resistance, MPa ∙ m0.5 - 2,4 Hardness (Hv10) - 1250 Density before sintering, g / cm3 - 3,26 Density after sintering, g / cm3 - 6,04 Chemical Composition ZrO2+HfO2+Y2O3 +Al2O3 *, массовый % - (>99.9) Y2O3, mass % - 9.3 Al2O3, mass % - 0.05 SiO2, mass % - ≤ 0.02 Fe2O3, mass % - ≤ 0.01 Na2O, mass % - - HfO2, mass % - - * The presence of other impurities is allowed, but not more than the limits established in GOST 21907 Note: To match the sintering temperature with the program temperature, make sure your furnace is calibrated correctly. Lower temperatures will create a deeper shade and lower transparency. Higher temperatures will create a lighter shade and higher transparency, but worse material strength. Models Supertranslucent material is presented in the form of blanks: - diameter 98.5 mm for open CAD / CAM systems - diameter 95.0 mm compatible with the Zirkonzahn® system Thickness of white and pre-shade blanks: 10, 12, 14, 16, 18, 20, 22, 24 (25) mm
