Features of Preshaded Zirconia
The preshaded zirconia that covers all 16 shades of the VITA Classic shade guide, With pre-shaded zirconia there is no need for laboratory technicians to shade each unit, saving production time.
-
Consistent VITA® Classic Shade Match
Strictly follow up VITA® Classic Shade from the R & D phase and also by the standard production with shade match.
-
Glazed with Bloomden CeramStar Glaze/Stain Kit
Preparation: Multilayer crown bridge after milled and sintered and then glazed.
-
Incisal Translucency and appearance
The translucency of preshaded zirconia and the additional light refraction from the preshaded zirconia phase results in a natural incisal translucency.
