Reliable Performance

for Everyday Restorations

5-Layer Color Gradient

Natural shade transitions from cervical to incisal.

High Strength Performance

Supports a wide range of crown and bridge indications.

Consistent Aesthetic Results

Stable color distribution improves restoration predictability.

Versatile Clinical Applications

Suitable for anterior and posterior restorations.

Built-In Shade Technology

ST combines pre-dyed zirconia with a 5-layer color gradient, offering dental labs a fast, reliable, and aesthetically natural solution for high-quality restorations.
Pre-Colored for Efficiency

ST Multilayer Zirconia comes pre-colored, eliminating the need for internal staining. This reduces manual work and ensures consistent shade reproduction for every restoration, improving laboratory efficiency.

5-Layer Gradient Design

Featuring five seamless color layers, ST provides smooth transitions from cervical to incisal regions. This gradient delivers natural aesthetics, balanced translucency, and reliable results across crowns, bridges, and full-contour restorations.
