Product Introduction

Products Description

VHF Cad Cam Preshade Dental Zirconia Block A3 zirconia disc

Zotion's Preshaded Zirconia Blocks offer uniform shades and natural transitions for all-ceramic restorations with high aesthetic demands. The A3 shade discs are pre-shaded and can be fired directly to achieve a natural shade without the need for manual staining.

Advantage	Practical Implementation	User Benefit
✅ Preshaded A3 Coloring	Factory pre-coloring in Vita A3 shade with natural transition gradients	No need for manual staining; ensures consistent color and saves time
✅ High Flexural Strength	Contains ≥ 99% ZrO₂ with flexural strength over 1200 MPa	Suitable for multi-unit bridges and posterior restorations; fracture-resistant
✅ Excellent Translucency	Fine grain size and high material density ensure up to 43% light transmittance	Provides natural esthetics, ideal for anterior restorations
✅ Wide System Compatibility	Standard disc sizes (Ø98mm/Ø95mm) fit VHF and open CAD/CAM systems	Easy installation without the need for additional adapters
✅ Low Shrinkage Rate	Consistent sintering shrinkage (~20% ± 0.5%) with precise sintering curve support	High dimensional accuracy and better marginal fit
✅ Fast & Stable Sintering	Compatible with both regular and fast sintering protocols (Recommended: ~1500°C)	Saves processing time, ideal for batch work, and compatible with Zotion F2 furnace

by heating from room temperature to 300°C, gradually increasing the temperature at a rate of 7.5°C per minute over a 40-minute period. Once at 300°C, raise the temperature to 800°C, maintaining a heating rate of 5°C per minute, which will take 100 minutes. From 800°C, increase the temperature to 1300°C at a rate of 2.5°C per minute, taking 200 minutes to reach. Then, elevate the temperature from 1300°C to 1530°C at a rate of 5°C per minute, which will take 46 minutes. Once 1530°C is reached, hold the temperature for 120 minutes. Finally, allow the material to cool naturally from 1530°C to room temperature, with a cooling rate of -121°C, and keep the furnace door closed until the temperature has returned to room temperature.

Tips: The maximum speed is recommended to be less than 20°C/min. Keep the furnace door closed until the temperature drops to room temperature for natural cooling.
