VITA YZ ST are super translucent ZrO2 blanks for the fabrication of monolithic and partially veneered posterior tooth restorations.
VITA YZ ST blanks are available in several versions:
VITA YZ STWhite (unstained)
VITA YZ STColor (monochromatic, tooth shades)
VITA YZ STMulticolor (polychromatic, tooth shades)
reliably reproduce tooth shades using a material system with ideally matched components
create highly accurate restorations with material blanks with edge stability, homogeneous microstructures and tested sintering properties
achieve efficient, solid and esthetic results thanks to tooth-shaded precolored (multi)color blanks with good shade matching to the VITA classical A1–D4 shade guide
VITA YZ ST is for:
Type II, class 5
Fully-anatomical crowns and up to 14-unit** bridges* in the anterior and posterior tooth region
Fully and partially veneered single-tooth and up to 14-unit bridge** substructures in the anterior and posterior tooth region
Single-tooth and up to 14-unit bridges* on screw-retained restorations applied directly in the anterior and posterior tooth region
Inlays, onlays, veneers
Occlusal veneers (table tops)
No, mechanical surface processing may cause damage to the structure in the sintered condition. This can lead to phase transformation of the zirconia and surface tensions, due to the distortion of the crystal lattice. Fissures or late cracks in the veneering porcelain are also possible after inserting the restoration.
