Eva Zirconia Ultima
Advanced Multilayer Technology for Realistic Shades
Advanced Zirconia for Durable, Natural-Looking Posterior Restorations
Eva Zirconia Ultima is a super-translucent, multilayered zirconia designed to replicate the natural shade gradient of teeth, making it an excellent choice for monolithic posterior restorations. It combines high flexural strength with great translucency, providing durable restorations that maintain their smoothness and luster over time. Ultima requires less tooth reduction compared to traditional glass ceramics and metal-ceramic crowns, supporting more conservative dental preparations.
Clinical Benefits
- Provides durable, super-translucent restorations that maintain strength in posterior regions.
- Features a multilayered shade gradient for natural-looking crowns and bridges.
- Requires minimal tooth reduction, preserving healthy tooth structure.
- Maintains a smooth, polished surface to reduce plaque buildup and wear on opposing teeth.
Key Features
Multilayered Shade Gradient:
Mimics the natural transition of tooth color from incisal to cervical, enhancing the lifelike appearance of posterior crowns and bridges.
Super-Translucent:
Offers translucency around 38–40%, balancing aesthetics with strength for posterior use.
High Flexural Strength:
Typically around 748 MPa or higher, ensuring resistance to fracture and wear under occlusal forces.
Reduced Tooth Preparation:
Requires less tooth reduction than glass ceramics and metal-ceramic crowns, preserving more natural tooth structure.
Surface Smoothness and Luster:
Maintains its polished surface during function, reducing plaque accumulation and wear on opposing teeth.
Biocompatible and Metal-Free:
Made from yttria-stabilized zirconia, safe for all patients including those with metal sensitivities.
CAD/CAM Compatible:
Designed for precise digital milling and sintering workflows, ensuring excellent fit and efficiency.
Ideal for Posterior Use:
Particularly suited for monolithic crowns and bridges in molar and premolar regions.
