Recommended Milling & Polishing Workflow:

Step 1: Milling (15-20 minutes)

• Use wet milling for optimal results
• Recommended bur: 1.0mm diameter or smaller
• Milling speed: 30,000-60,000 RPM
• Feed rate: Moderate to fast

Step 2: Polishing (5-10 minutes)

• Remove milling tabs and smooth margins
• Use diamond polishing paste or silicone polishers
• Progress from coarse to fine grits
• Final polish with felt wheel and diamond paste

Step 3: Cementation

• Clean restoration with alcohol or phosphoric acid
• Apply the silane coupling agent
• Use resin-based luting cement (dual-cure or light-cure)
• Follow the cement manufacturer's instructions

Frequently Asked Questions (FAQ)

💡 Product Features & Technology

Q: Does this glass-ceramic require crystallization or firing?
A: No. U-ZEE Direct Mill Glass-Ceramic is fully crystallized and ready to use immediately after milling and polishing. This eliminates the need for a furnace, saving time and equipment costs.

Q: How is U-Zee different from traditional lithium disilicate blocks?
A: U-ZEE uses Microcrystal Control Technology with nano-size crystals that are already fully crystallized. Traditional lithium disilicate blocks require firing at 820-850°C for 20-30 minutes to achieve final strength and shade. U-Zee skips this step entirely.

Q: What is the flexural strength of U-Zee?
A: U-Zee has a flexural strength of 280MPa, which is sufficient for single crowns, veneers, inlays, and onlays. While lower than fired lithium disilicate (420 MPa), it's ideal for esthetic cases where speed is critical.

Q: Can I achieve the same esthetics as traditional lithium disilicate?
A: Yes! U-Zee offers natural translucency and lifelike shading with 12 available Vita shades in both HT (High Translucency) and LT (Low Translucency) options, providing excellent esthetic results.

⏱️ Workflow & Production Time

Q: How long does it take to produce a single restoration?
A: Approximately 30 minutes total, including design (5-10 min), milling (15-20 min), and polishing (5-10 min). This makes U-Zee ideal for same-day dentistry and urgent cases.

Q: Is this material suitable for chairside dentistry?
A: Absolutely! U-Zee is specifically designed for chairside workflows. You can design, mill, polish, and seat a restoration in a single appointment without needing a furnace.

Q: Can I use U-Zee in a dental laboratory setting?
A: Yes! U-Zee is perfect for labs handling urgent cases, same-day requests, or high-volume production where furnace capacity is limited. It streamlines workflow and increases throughput.

🔧 Milling & Processing

Q: What milling parameters should I use?
A: Use wet milling with a 1.0mm or smaller diameter bur at 30,000-60,000 RPM. Moderate to fast feed rates work well. U-Zee mills smoothly with minimal chipping.

Q: Which CAD/CAM systems are compatible with U-Zee?
A: U-ZEE works with most open CAD/CAM milling systems including Roland, VHF, Imes-Icore, Zirkonzahn, and similar machines. The C14 block size (18×13×15mm) fits standard block holders.

Q: How do I polish U-Zee restorations?
A: After milling, remove tabs and smooth margins with diamond burs. Polish using silicone polishers or diamond paste, progressing from coarse to fine grits. Finish with a felt wheel and fine diamond paste for high gloss.

Q: Can I adjust or grind U-Zee after milling?
A: Yes, you can make minor adjustments with diamond burs. After any adjustment, re-polish the affected areas to restore surface gloss and smoothness.

🎨 Clinical Applications

Q: Which restorations can be made with U-Zee?
A: U-ZEE is ideal for single crowns (anterior and posterior), veneers, inlays, and onlays. It's best suited for cases requiring excellent esthetics with moderate strength requirements.

Q: Is U-ZEE strong enough for posterior teeth?
A: Yes, for single posterior crowns with normal occlusion. The 280 MPa flexural strength is adequate for most posterior applications. For high-load cases or bruxers, consider traditional lithium disilicate or zirconia.

Q: What cementation protocol should I use?
A: Clean the restoration with alcohol or phosphoric acid, apply silane coupling agent, and use resin-based luting cement (dual-cure or light-cure). Follow your cement manufacturer's instructions for best results.

📦 Ordering & Packaging

Q: How many blocks come in each box?
A: Each box contains 5 blocks of the same shade and translucency. Each C14 block measures 18×13×15mm and can produce multiple single-unit restorations.

Q: What shades are available?
A: U-ZEE is available in 12 Vita shades: BL1-BL4 (bleach shades), A1-A3.5, B1-B2, and C1-C2. Each shade is available in both HT (High Translucency) and LT (Low Translucency).

Q: Do you offer sample blocks for testing?
A: Yes! We offer sample boxes for qualified dental laboratories and chairside practices. Contact our sales team to request samples and experience the U-ZEE advantage.
