Upcera ST Multilayer Zirconia is designed for dental labs that require exceptional esthetics, predictable shade transitions, and strong mechanical performance for both anterior and posterior restorations. As part of the ST (Super Translucent) series, ST Multilayer features a smooth, natural 5-layer gradient that replicates the optical behavior of enamel and dentin without needing manual infiltration. Supplied as precision-milled zirconia blocks and dental zirconia discs, this zirconia dental material supports consistent results across esthetic and functional cases.
From single anterior crowns to multi-unit bridges and full-contour esthetic restorations, ST Multilayer delivers the perfect balance of translucency, strength, and shade accuracy—making it one of the most versatile zirconia multilayer materials in the Upcera family.
Natural 5-Layer Gradient for Lifelike Esthetics
Upcera ST Multilayer is engineered using a multi-layer shading technique that gradually transitions from cervical-opacity to incisal-translucency. This creates an enamel-like depth and natural esthetic effect ideal for cosmetic dentistry using advanced zirconia blanks.
Esthetic advantages:
- Built-in 5-layer shade gradient
- Natural transition between dentin and enamel shades
- Enhanced incisal translucency for lifelike appearance
- Consistent shade reproduction across multiple units
- Smooth blending that requires minimal post-processing
- Ideal for anterior and smile-zone restorations
ST Multilayer provides predictable esthetics while saving chairside and lab time otherwise spent on staining or custom infiltration, making it a preferred choice among zirconia blocks dental.
Professional Features & Technical Highlights
Upcera ST Multilayer is manufactured using refined zirconia powder and advanced multilayer coloration technology. This ensures high optical quality, strong durability, and consistent performance for every restoration produced from zirconium blocks.
Key features include:
- Super translucent multilayer zirconia
- Strength suitable for anterior + posterior restorations
- Excellent shade accuracy across all layers
- Smooth milling behavior with minimal chipping
- Predictable sintering curve for precise fitting
- Compatible with all open 98 mm CAD/CAM systems
- Natural esthetics straight out of sintering
Its balance of optical depth and functional integrity makes it ideal for premium full-contour restorations using zirconia dental blanks.
Applications & Indications
ST Multilayer is a multi-purpose zirconia suited for a wide variety of restorative needs across modern dental lab materials workflows.
Ideal for:
- Anterior esthetic crowns
- Posterior crowns requiring strength and beauty
- 2–3 unit bridges (anterior or posterior)
- Implant-supported crowns
- Cosmetic full-contour restorations
- Multi-unit bridges with shade consistency
- Smile designs or esthetic mock-up cases
For even higher translucency, technicians may pair it with Explore Esthetics, and for deeper gradients, TT Multilayer may be preferred—helping labs optimize zirconia blocks price vs. esthetic outcome.
Optimized for High-Precision CAD/CAM Production
ST Multilayer is engineered for the demanding needs of modern dental labs, providing consistent milling accuracy and efficient workflow compatibility when using dental zirconia discs.
Workflow advantages:
- Smooth milling with reduced bur wear
- Stable disc density for predictable nesting
- Accurate marginal precision and occlusal detailing
- Minimal post-sinter finishing needed
- Works well with both rapid and standard sintering cycles
- Polishes to a natural enamel-like shine
- Compatible with glaze and stain systems for enhancements
The multilayer shading ensures restorations emerge from the furnace with natural color gradation, reducing manual finishing time for labs working with zirconium dental restorations.
