- Product Introduction
Products Description
3D multilayer zirconia discs are high-performance restorative materials designed specifically for dental CAD/CAM systems.
Manufactured with advanced multilayer technology, they combine excellent translucency with outstanding strength, allowing for natural and aesthetic full-ceramic restorations without the need for veneering porcelain.
Specifications
| Parameter | Value | Description |
|---|---|---|
| Translucency | 43%–55% | Simulates the natural enamel translucency, far exceeding conventional zirconia |
| Flexural strength | 600–1100 MPa | Meets the strength requirements of various restorations and ensures long-term stability |
| Density | 6.05 g/cm³ | High density provides superior wear resistance and fracture toughness |
| Structure | Multilayer gradient (6–15 layers) | Creates a natural transition from cervical to incisal |
| Material | 3Y-TZP / 4Y-TZP / 5Y-TZP hybrid | Different yttria contents are used in different layers to optimize performance |
II. Core Advantages and Performance
1. 3D Aesthetic Effects: Natural Tooth-Like Appearance
Gradient translucency and color system:
Translucency increases naturally from cervical (43%) to incisal (55%), perfectly mimicking the optical properties of natural teeth
Multilayer coloration (6–15 layers) achieves a seamless transition from dentin to enamel
No veneering porcelain is needed-the disc alone produces natural depth, vitality, and gloss
Clinical aesthetic benefits:
Anterior restorations show a "vital tooth" translucency, avoiding the "chalky white" look of traditional zirconia
Compatible with VITA shade systems, reducing shade-matching steps and improving efficiency
Marginal translucency blends harmoniously with gingival tissues
2. Structural Reinforcement: Excellent Mechanical Performance
Gradient strength design:
Cervical strength reaches 1050–1200 MPa to resist occlusal forces
Incisal strength is about 700 MPa, providing the right elasticity
This "strong-at-the-base, tough-at-the-top" structure distributes stress evenly and enhances fracture resistance
Clinical applications:
Single crowns: High marginal stability, reduced chipping risk
Long-span bridges: Supports up to 14 units
Posterior restorations: Withstands up to 1200 MPa of occlusal force, extending service life
3. CAD/CAM Processing Efficiency & Clinical Convenience
CAD/CAM-friendly:
Easy to mill in the pre-sintered state, with minimal bur wear; milling accuracy reaches 2–10 μm
Excellent dimensional stability after sintering, with <0.1% deformation for precise fit
Clinical benefits:
Full crowns can be completed from a single block, eliminating the traditional metal framework + porcelain layering workflow
Simplified process: design → milling → sintering → glazing, shortening the treatment cycle
Outstanding biocompatibility with no metal components, reducing allergy risks
Compatible with conventional dental cements, providing stable bonding strength
4. Versatile Applications
| Application | Advantages |
|---|---|
| Anterior aesthetic restorations | High translucency (46%–55%) for natural gloss; ideal for veneers and crowns |
| Posterior functional restorations | High strength (800–1100 MPa) for chewing load; suitable for inlays/onlays |
| Long-span fixed bridges | Gradient strength ensures overall stability; ideal for multi-unit bridges |
| Implant abutments | Excellent implant compatibility with aesthetic soft-tissue outcomes |
| Full-arch denture frameworks | Lightweight and high-strength, improving patient comfort |
Comparison Table
| Feature | 3D Multilayer Zirconia | Traditional PFM (Porcelain-Fused-to-Metal) | Monolayer Zirconia |
|---|---|---|---|
| Aesthetic Effect | ★★★★★ Natural gradient without veneering porcelain | ★★★☆☆ Metal may show through at the margins | ★★★☆☆ Uniform translucency with limited depth |
| Strength | ★★★★☆ 600–1100 MPa | ★★★★☆ Good but limited by the metal framework | ★★★★★ HT type > 1200 MPa |
| Processing Complexity | ★★★☆☆ One-step fabrication | ★★★★★ Multi-step process with high technical requirements | ★★★☆☆ Simple, but aesthetic outcome is limited |
| Restoration Thickness | ★★★★★ Can achieve thinner margins (0.3 mm) | ★★★☆☆ Requires enough space to accommodate metal | ★★★★☆ Balanced between strength and thickness |
| Long-term Stability | ★★★★★ Highly resistant to discoloration and chipping | ★★★★☆ Marginal porcelain may chip | ★★★★★ Excellent, though translucency is limited |
