Multilayer SHT Zirconia Blanks
Characteristics
Dental Ceramic Zirconia blocks is a new type of composite biological material, with good transparency, excellent color, more realistic shape, and hard to collapse porcelain.
Color gradient
6 layers of natural color transition,matching color gradient of natural tooth from cervical to incisal.
Translucency gradient
From 57% translucency in incisal to 43% in cervical,it shows gradient decrease,achieving life-like transparency of natural tooth enamel while in the mean time low transparency in cervical have effective opaque!
Strength gradient
Strength shows gradient from 600Mpa to 900Mpa,achieving low strength in occlusion and causing no harm to opposing dentin.High strength in base part realize long bridge restoration!
multilayer dental zirconia
Amann girrbach,Sirona cerec,Zirkonzahn,Vhf CAD CAM milling system we can supply.
Natural Color Transition,No Need Dyeing
