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 (white, porous material)
• Important: Ensure adequate thickness for veneers (minimum 0.5-0.8mm recommended)

Step 2: Staining (10-20 minutes)

• Apply zirconia-compatible staining liquid by immersion or the brush technique
• The porous pre-sintered structure allows stain penetration into the material
• Staining must be done BEFORE sintering for internal coloration
• Allow stained restoration to dry completely before sintering
• Multiple layers can be applied for the desired shade intensity

Step 3: Sintering (8-10 hours)

• Place stained restoration in a sintering furnace
• Follow the recommended sintering cycle at 1450°C (see table above)
• During sintering, the material densifies and the stain becomes permanently fixed
• Material shrinks 20-25% and becomes fully dense and strong (650 MPa)
• Ensure proper support to prevent warping
• Allow complete cooling before handling

Step 4: Glazing (Optional) & Cementation

• Optional: Apply glaze for enhanced surface finish (fire at 800-900°C)
• 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

⚠️ Important Note: Staining MUST be performed before sintering. The pre-sintered zirconia is porous and allows stain penetration. After sintering at 1450°C, the material becomes fully dense and staining liquid cannot penetrate - only surface coloration would be possible.

Frequently Asked Questions (FAQ)

💎 Product Features & Ultra Translucency Advantages

Q: What makes UT Zirconia different from SHT and ST zirconia?
A: UT (Ultra Translucent) Zirconia has 49% translucency – the highest in our series – compared to SHT's 47% and ST's 43%, providing maximum light transmission and the most natural, enamel-like appearance. However, UT has lower strength (650 MPa vs SHT's 1000 MPa and ST's 1200 MPa), making it specifically designed for anterior restorations only.

Q: What is the flexural strength of UT Zirconia?
A: UT White Zirconia has a flexural strength of 650 MPa, which is approximately 1.5-2x stronger than lithium disilicate (360-470 MPa) and sufficient for anterior crowns, veneers, and short-span anterior bridges in low-stress areas.

Q: Is 650 MPa strong enough for my restorations?
A: 650 MPa is sufficient for anterior restorations only: veneers, anterior crowns (incisors, canines), and short-span anterior bridges (3 units max). It is NOT recommended for posterior teeth, molars, long-span bridges, or high-stress areas. For those cases, choose SHT (1000 MPa), ST (1200 MPa), or HT (1300 MPa).

Q: What does 49% translucency mean clinically?
A: 49% translucency – the highest in our series – means the material allows maximum light to pass through, creating exceptional natural depth, vitality, and enamel-like appearance. This makes UT ideal for veneers and anterior crowns where esthetics is paramount.

🔧 Milling & Processing

Q: Which CAD/CAM systems are compatible with UT Zirconia?
A: UT White 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: What is the linear shrinkage rate?
A: UT 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.

Q: Can I adjust the sintering temperature?
A: We recommend following the standard 1450°C sintering temperature for optimal translucency and strength. Deviating from this temperature may affect the final properties.

🎨 Staining & Esthetics

Q: Can UT White Zirconia be stained?
A: Yes! UT White Zirconia must be stained in the pre-sintered state (after milling, before sintering). The porous pre-sintered structure allows zirconia-compatible staining liquid to penetrate into the material. During the subsequent sintering at 1450°C, the stain becomes permanently fixed as the material densifies.

Q: Do I need to glaze UT Zirconia restorations?
A: Glazing is optional. While UT Zirconia can be polished to a high shine, applying a glaze can provide additional surface smoothness and esthetic enhancement. Use zirconia-compatible glaze materials.

Q: How does the 49% translucency affect esthetics?
A: The 49% translucency provides the most natural esthetics in our series, offering maximum light transmission and enamel-like appearance. This creates exceptional depth, vitality, and lifelike results, making UT ideal for veneers and high-esthetic anterior crowns.
