3D-Pro Multilayer Zirconia Disc 98mm - Premium Gradient Dental Block

Milling & Processing Workflow:

Step 1: CAD Design & Milling (30-45 minutes)

• Design restoration with 20-25% enlargement to compensate for sintering shrinkage
• CRITICAL: Orient restoration correctly - ensure gradient flows from cervical (bottom/high strength) to incisal (top/high translucency)
• Use wet milling for optimal results and minimal tool wear
• Recommended bur: 1.0-2.0mm diameter carbide or diamond burs
• Milling speed: 20,000-40,000 RPM
• Feed rate: Moderate (adjust based on detail complexity)
• Mill in pre-sintered state (dual-gradient, porous material)

Step 2: Sintering (8-10 hours) – NO STAINING NEEDED

• Place milled restoration directly in the sintering furnace (skip staining step)
• Follow the recommended sintering cycle at 1480°C (see table above)
• During sintering, the pre-integrated dual gradient becomes fully developed and fixed
• Material shrinks 20-25% and becomes fully dense with gradient strength (650-1200 MPa)
• Ensure proper support to prevent warping
• Allow complete cooling before handling

Step 3: Glazing (Optional) & Cementation

• Optional: Apply glaze for enhanced surface finish (fire at 800-900°C)
• Optional: Apply surface stains for fine characterization if needed
• Check fit and make minor adjustments if needed
• Clean thoroughly before cementation
• Use resin-modified glass ionomer or resin cement
• Consider airborne particle abrasion for improved bond strength

🎨 Dual-Gradient Orientation is Critical: Always ensure the restoration is oriented correctly during milling. The gradient should flow from cervical (high strength 1200 MPa, lower translucency 43%) to incisal (lower strength 650 MPa, high translucency 49%) to achieve optimal performance and natural-looking results.

Why Choose 3D-Pro Zirconia?

The 3D-Pro Multilayer Zirconia is our flagship premium product, developed for cases requiring the ultimate combination of strength and esthetics. The revolutionary dual-gradient technology provides:

• Dual-Gradient Innovation: Unique combination of strength gradient (650-1200 MPa) AND translucency gradient (43%-49%) in one disc
• Optimized Performance: Maximum strength where needed (cervical), maximum esthetics where visible (incisal)
• Versatile Application: Suitable for both anterior AND posterior restorations - the only multilayer disc with this capability
• Natural Tooth Mimicry: Dual gradient replicates natural tooth structure better than any other zirconia
• Time Savings: Eliminate manual staining and layering (save 20-30 minutes per case)
• Consistent Results: Factory-controlled dual gradient ensures predictable, batch-to-batch outcomes
• Full-Arch Optimized: Perfect for full-arch cases requiring both strength and esthetics

3D-Pro vs ST Multilayer vs SHT Multilayer vs UT Multilayer

Recommendation: Choose 3D-Pro for full-arch cases or when you need both maximum strength (posterior) and maximum esthetics (anterior) in one disc. Choose ST/SHT/UT Multilayer for anterior-only cases with specific strength requirements.

Frequently Asked Questions (FAQ)

💎 Product Features & Dual-Gradient Technology

Q: What makes 3D-Pro different from other multilayer zirconia?
A: 3D-Pro features revolutionary dual-gradient technology - both strength (650-1200 MPa) AND translucency (43%-49%) gradients in one disc. Other multilayer zirconia only have a color gradient with uniform strength and translucency. This makes 3D-Pro the only disc suitable for both anterior esthetics AND posterior strength.

Q: How does the strength gradient work?
A: The strength gradient flows from 1200 MPa in the cervical area (maximum strength for load-bearing) to 650 MPa in the incisal area (optimized for esthetics). This mimics natural tooth structure and provides strength where needed while maintaining esthetics where visible.

Q: How does the translucency gradient work?
A: The translucency gradient flows from 43% in the cervical area (body color) to 49% in the incisal area (maximum translucency). This creates natural depth and vitality that replicates real tooth enamel.

Q: Can 3D-Pro be used for posterior restorations?
A: Yes! 3D-Pro is the only multilayer disc in our series suitable for posterior restorations, thanks to its 1200 MPa strength in the cervical area. Other multilayer discs (ST, SHT, UT) are optimized for anterior use only.

🔧 Milling & Processing

Q: How do I orient the restoration correctly during milling?
A: Critical: The dual gradient must flow from cervical (high strength 1200 MPa, lower translucency 43%) to incisal (lower strength 650 MPa, high translucency 49%). Position the restoration so the cervical margin is at the bottom of the disc and the incisal edge is at the top.

Q: Which CAD/CAM systems are compatible with 3D-Pro?
A: 3D-Pro Multilayer Zirconia Disc (98mm) is compatible with most open CAD/CAM milling systems, including Roland, VHF, Amann Girrbach, Sirona, and similar 98mm disc systems.

Q: What milling parameters should I use?
A: Recommended parameters:
• Bur size: 1.0-2.0mm diameter carbide or diamond burs
• Milling speed: 20,000-40,000 RPM
• Feed rate: Moderate (adjust based on detail)
• Milling type: Wet milling preferred
• Enlargement factor: 20-25% to compensate for sintering shrinkage

Q: Do I need to stain before sintering?
A: No! The dual gradient (color, strength, and translucency) is already integrated. Simply mill with correct orientation and sinter – the gradient will fully develop during sintering. This saves 20-30 minutes per case.

🎨 Shade Selection & Esthetics

Q: How many shade options are available?
A: 3D-Pro is available in 20 comprehensive shades:
• 16 Vita shades: A1, A2, A3, A3.5, A4, B1, B2, B3, B4, C1, C2, C3, C4, D2, D3, D4
• 4 Bleach shades: BL1, BL2, BL3, BL4
Each shade features the same dual gradient structure.

Q: Can I still apply surface stains for characterization?
A: Yes! While the dual gradient is pre-integrated, you can still apply surface stains after sintering for additional characterization or fine-tuning.

Q: How does the dual gradient affect esthetics?
A: The dual gradient creates the most natural-looking restorations by mimicking real tooth structure - stronger and more opaque at the cervical area (like dentin), more translucent at the incisal area (like enamel). This is superior to single-gradient discs.

🏥 Clinical Applications

Q: What cementation protocol should I use?
A: For 3D-Pro Zirconia restorations:
1. Clean restoration thoroughly
2. Consider airborne particle abrasion (50μm Al₂O₃) for improved bond
3. Use resin-modified glass ionomer or resin cement
4. Follow the cement manufacturer's instructions
5. Ensure complete seating and remove excess cement

Q: Is 3D-Pro suitable for full-arch restorations?
A: Yes! 3D-Pro is specifically optimized for full-arch cases. The dual gradient provides maximum strength for posterior teeth (1200 MPa) and maximum esthetics for anterior teeth (49% translucency) - all from one disc type.

Q: Can 3D-Pro be used for long-span bridges?
A: Yes! With 1200 MPa strength in the cervical area, 3D-Pro is suitable for long-span bridges (4+ units). The dual gradient ensures both strength and esthetics.

Q: Is 3D-Pro suitable for bruxers?
A: Yes! The 1200 MPa strength in the cervical area makes 3D-Pro suitable for bruxers and patients with heavy occlusal forces, especially for posterior restorations.

📦 Ordering & Packaging

Q: What thickness and shade combinations are available?
A: 3D-Pro is available in:
• 7 thickness options: 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm
• 20 shade options: 16 Vita shades (A1-A4, B1-B4, C1-C4, D2-D4) + 4 Bleach shades (BL1-BL4)
