Modern dentistry is no longer just about function—it’s about delivering natural-looking,
durable, and efficient restorations. The Starcona Multi-layered Zirconia Discs represents a
major advancement in zirconia technology by integrating color, translucency, and strength gradients into a single disc.
For dental labs and clinicians aiming to reduce manual steps while improving esthetic
outcomes, multilayer zirconia has become a workflow game changer.
What is Multi-layered Zirconia and Why Does It Matter?
Unlike traditional monolithic or unshaded zirconia, multilayer zirconia discs are engineered with pre-integrated layers that mimic natural tooth anatomy:
● Cervical Layer: Higher strength, lower translucency
● Body Layer: Balanced optical and mechanical properties
● Incisal Layer: Higher translucency, lower strength
This gradient design closely replicates natural dentin and enamel structure, resulting in highly lifelike restorations straight out of the mill.
Industry Benchmark Performance
Modern multilayer zirconia discs typically achieve:
● Strength Range: 650 MPa – 1200 MPa depending on layer
● Translucency Gradient: ~43% to 49% for natural light transmission
This combination allows a single disc to be used for both anterior and posterior
restorations, optimizing inventory and production efficiency.
Technical Advantages of Starcona Multi-layered Zirconia Discs
1. Gradient Strength Engineering Multilayer zirconia is designed with functional zoning:
● Up to 1200 MPa strength in cervical regions for load-bearing areas
● Lower strength (~650 MPa) in incisal zones for enhanced esthetics
This ensures restorations are strong where needed and translucent where visible.
2. Integrated Translucency Gradient
With translucency increasing from cervical to incisal:
● Improved light diffusion
● Reduced opacity in visible zones
● Natural enamel-like appearance
Typical multilayer zirconia achieves around 47% translucency, delivering a strong balance of esthetics and durability
3. Pre-Shaded Multi-Layer Technology
Starcona discs eliminate the need for extensive manual staining:
● Built-in shade gradients (VITA-based shades)
● Consistent batch-to-batch color reproduction
● Reduced technician variability
This translates into predictable esthetic outcomes with less labor.
4. CAD/CAM Optimization
Designed for modern digital workflows:
● Compatible with 98mm open CAD/CAM systems
● Supports leading mills (Roland, VHF, Amann Girrbach, etc.)
● Stable shrinkage (~20–25%) for precise fit after sintering
Clinical Indications: One Disc, Multiple Solutions
The Starcona Multi-layered Zirconia Discs is highly versatile:
● Anterior crowns (high esthetic demand)
● Posterior crowns (high occlusal load)
● Bridges (short to long span depending on design)
● Full-arch restorations
● Implant-supported prosthetics
Because of its strength-translucency balance, it reduces the need to switch between multiple zirconia types.
Why Starcona Multi-layered Zirconia Discs Stand Out
Starcona combines advanced material science with real-world lab efficiency, making it a
reliable choice for modern dental production.
Core Differentiators
● Precision-engineered gradient structure
● High flexural strength for posterior durability
● Natural translucency for anterior esthetics
● Reliable sintering behavior for consistent fit
● Reduced need for manual characterization
