In today’s digital dentistry landscape, dental laboratories and clinicians demand materials that
balance mechanical strength, esthetics, and workflow efficiency. The Starcona Super
Unshaded Zirconia Discs delivers exactly that—offering a high-performance zirconia solution
designed for full customization and predictable outcomes across a wide range of indications.
What Makes Unshaded Zirconia Essential in Advanced
Dental Labs?
Unlike pre-shaded zirconia, unshaded discs provide a neutral white base, allowing technicians to fully control the final restoration using infiltration liquids and staining techniques. This is especially valuable for:
● Complex anterior restorations requiring individualized characterization
● Multi-unit prosthetics with nuanced shade matching
● Implant-supported restorations where soft tissue interplay affects final esthetics
With unshaded zirconia, artistry meets engineering, enabling labs to deliver highly
personalized results without compromise.
Technical Excellence: Built for Strength and Esthetics
The Starcona Super Unshaded Zirconia Discs is engineered using a proprietary colloidal
pressing process, ensuring material homogeneity and structural integrity.
Key Technical Specifications
● Flexural Strength: Up to 1250 MPa
● Translucency: ~48% at incisal edge
● Material Type: High-translucency zirconia (unshaded)
● Shrinkage: Low and consistent during sintering
● Disc Diameter Compatibility: Standard 98mm CAD/CAM systems
Why This Matters Clinically
● High Strength (1250 MPa): Suitable for both anterior and posterior restorations,
including high-load occlusal zones
● Balanced Translucency (48%): Achieves natural enamel-like light transmission without
sacrificing durability
● Low Shrinkage: Improves marginal fit and reduces post-sintering adjustments
Compared to ultra-translucent zirconia (~650 MPa), which is often limited to anterior cases, this material offers a superior strength-to-esthetic ratio, making it highly versatile in daily lab production
Indications: Versatility Across Restorative Cases
The Starcona Super Unshaded Zirconia Discs supports a wide range of applications:
● Single-unit crowns (anterior & posterior)
● Multi-unit bridges
● Full-arch restorations (4+ units)
● Implant-supported prosthetics
Its mechanical reliability allows technicians to confidently fabricate long-span restorations,
unlike lower-strength zirconia alternatives.
Optimized for Digital Dentistry Workflow
CAD/CAM Integration
Designed for compatibility with major milling systems, these discs streamline digital workflows:
● Accurate milling in pre-sintered (green state) form
● Predictable enlargement factors for sintering compensation
● Reduced tool wear due to consistent density
Sintering Performance
● Stable shrinkage behavior ensures precise marginal adaptation
● Compatible with standard zirconia sintering protocols
Finishing & Characterization
● Ideal for liquid infiltration and external staining
● Allows layering techniques for high-end esthetics
Advantages for Dental Laboratories
1. Full Artistic Control
Unshaded zirconia enables technicians to replicate natural dentition with custom gradients and effects.
2. Consistency in Production
Uniform material structure ensures repeatable outcomes across batches.
3. Reduced Remakes
High strength and dimensional accuracy minimize fractures and misfits.
4. Cost-Efficient Workflow
● Less chairside adjustment
● Reduced finishing time due to accurate sintering behavior
Why Starcona Stands Out
The Starcona Super Unshaded Zirconia Discs is not just another zirconia blank—it’s engineered
for performance-driven labs.
Key Differentiators
● Proprietary manufacturing for enhanced density and strength
● High translucency without compromising durability
● Reliable sintering behavior for precision fit
● Made in the USA with strict quality control
