Features of Multilayer Zirconia
The multilayer zirconia has better shade gradation and more natural on aesthetics with translucency in the incisal area and bending strength for anterior and posterior teeth restorations with up to full arch bridges.
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.
Shade gradation more natural
Compared preshaded zirconia, the multilayer zirconia has better shade gradation because of its powder gradiaent to make various shade layers.
STML for Full arch bridges
STML is with highest bending strength 1100MPa for bridges and even long-span curved cases or full arch bridges by the lab-test.
