SHT Pre-Shaded Zirconia Disc(98mm) - High Translucency Dental Block

Milling & Processing Workflow:

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

• Design restoration with 20-25% enlargement to compensate for sintering shrinkage
• 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 (pre-shaded, 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 (see table above)
• During sintering, the pre-integrated color becomes fully developed and fixed
• Material shrinks 20-25% and becomes fully dense and strong (1000 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 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

⏱️ Time-Saving Advantage: Pre-shaded zirconia eliminates the 10-20 minute staining step required for white zirconia. Simply mill and sinter – the color is already integrated! This streamlines your workflow and ensures consistent shade results every time.

Why Choose SHT Pre-shaded Zirconia?

The SHT Pre-shaded Zirconia is developed for laboratories seeking maximum efficiency with enhanced esthetics. Combining 47% translucency (higher than ST's 43%) with pre-integrated color, it offers:

• Superior Esthetics: 47% translucency provides better light transmission and a more natural appearance than ST Pre-shaded
• Time Savings: Eliminate the staining step (10-20 minutes per case)
• Consistency: Factory-controlled shading ensures predictable, batch-to-batch color matching
• Simplified Workflow: Fewer steps mean fewer opportunities for error
• Cost Efficiency: No need for staining liquids or additional equipment
• Versatility: 20 shades (16 Vita + 4 Bleach) cover most clinical shade matching needs

SHT Pre-shaded vs SHT White vs ST Pre-shaded

Recommendation: Choose SHT Pre-shaded for anterior cases requiring enhanced esthetics with time-saving efficiency. Choose SHT White for custom shade control. Choose ST Pre-shaded for cases prioritizing maximum strength.

Frequently Asked Questions (FAQ)

💎 Product Features & Pre-shaded + High Translucency Advantages

Q: What makes SHT Pre-shaded Zirconia different from ST Pre-shaded?
A: SHT Pre-shaded has 47% translucency compared to ST Pre-shaded's 43%, providing superior light transmission and a more natural appearance for anterior esthetics. While SHT has slightly lower strength (1000 MPa vs 1200 MPa), it's optimized for esthetic-critical anterior cases.

Q: How many shade options are available?
A: SHT Pre-shaded Zirconia 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
This complete range covers all clinical needs from natural tooth colors to cosmetic whitening cases.

Q: Can I still apply surface stains for characterization?
A: Yes! While the base color is pre-integrated, you can still apply surface stains after sintering for additional characterization, incisal effects, or fine-tuning. The pre-shaded base provides a consistent foundation.

Q: Is the color consistent between batches?
A: Yes! Factory-controlled pre-shading ensures excellent batch-to-batch consistency. Unlike manual staining, which can vary based on technician's technique, pre-shaded zirconia delivers predictable results every time.

🔧 Milling & Processing

Q: Which CAD/CAM systems are compatible with SHT Pre-shaded Zirconia?
A: SHT Pre-shaded 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! This is the key advantage of pre-shaded zirconia. Simply mill and sinter – the color is already integrated. This saves 10-20 minutes per case and eliminates the staining step entirely.

Q: What is the linear shrinkage rate?
A: SHT Pre-shaded Zirconia has a linear shrinkage rate of approximately 20-25% during sintering. Always design and mill restorations with this enlargement factor to achieve the correct final size.

🎨 Shade Selection & Esthetics

Q: How do I choose the right shade?
A: Select the Vita shade that matches your patient's tooth color during the design phase. The 20 available shades include 16 VITA shades (A1-A4, B1-B4, C1-C4, D2-D4) + 4 bleach colors cover most clinical situations. For reference, A2 and A3 are the most commonly used shades.

Q: When should I use the Bleach shades (BL1-BL4)?
A: The Bleach shades (BL1-BL4) are specifically designed for cosmetic whitening cases where patients have undergone tooth bleaching or desire a brighter smile. BL1 is the brightest, while BL4 is slightly less bright. These shades are ideal for veneers, anterior crowns, and smile makeover cases.

Q: How does the 47% translucency affect esthetics?
A: The 47% translucency provides excellent esthetics for anterior restorations, offering superior light transmission compared to ST Pre-shaded (43%). This creates more natural depth, vitality, and lifelike appearance, making SHT Pre-shaded ideal for esthetic-critical cases.

🏥 Clinical Applications

Q: What cementation protocol should I use?
A: For SHT Pre-shaded 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 SHT Pre-shaded Zirconia suitable for anterior restorations?
A: Yes! With 47% translucency and factory-controlled shading, SHT Pre-shaded is excellent for anterior crowns and veneers where you need both superior esthetics and time-saving efficiency.

Q: Can SHT Pre-shaded Zirconia be used for bruxers?
A: For mild to moderate bruxers, SHT's 1000 MPa strength is sufficient. For severe bruxers or heavy occlusal forces, consider ST Pre-shaded (1200 MPa) or HT (1300 MPa) for maximum durability.

📦 Ordering & Packaging
