Zirconia dental material YZ® ST Multicolor

ZrO2zirconium dioxidefor dental bridges

Product information
VITA YZ® ST Multicolor are super-translucent zirconia (ZrO2) CAD/CAM blanks designed for the fabrication of monolithic and partially veneered posterior restorations. Available variants include VITA YZ® STWhite (unstained), VITA YZ® STColor (monochromatic tooth shades) and VITA YZ® ST Multicolor (polychromatic shade gradient).

Benefits

• Reliable shade reproduction through a coordinated material system and precolored blanks matched to VITA classical A1–D4.
• High precision milling and consistent fit thanks to homogeneous microstructure and stable edges.
• Efficient workflow with tested sintering properties; suitable for speed sintering depending on furnace and protocol.

Other variants
The VITA YZ family also includes related variants (e.g. VITA YZ XT, HT, T) available in White and Color options.

Indications

• Fully anatomical crowns and bridges (up to 14 units, subject to regional limitations).
• Fully or partially veneered single-tooth and multi-unit bridge frameworks in anterior and posterior regions.
• Single-tooth and implant-supported screw-retained bridges (see local indications).
• Inlays, onlays, veneers, partial crowns and occlusal veneers (table tops).

Usage notes
Bridges and bridge frameworks: maximum of two adjacent pontics in standard indications. In Canada, VITA YZ® ST use for bridges may be limited to a maximum of six units with up to two adjacent pontics. Follow manufacturer processing recommendations for coloring, sintering and post-processing.
