Product: EVEREST Multilayer AT Zirconia block

EVEREST Multilayer AT is a multi-layered Zirconia block for Anterior Teeth prosthesis from UNC International. Dedicated to anterior teeth, the multilayer clock allows for fabrication of anterior prosthesis with optimized flexural strength (850~1,150 MPA) and 16 shades.

EVEREST Multilayer AT consists of four layers: Cervical (35%); C-Transition (15%); E-Transition (25%); and Enamel (25%)

The four-layer structure has high-level colour matching based on the VITA Shade Guide. It is also possible to fabricate the prosthesis without the colouring process.

Other advantages include:

• High translucency for aesthetic restorations
• Excellent strength
• High fracture toughness
• High-density particle structure and unique manufacturing technology for stable results after milling.
• Excellent marginal fitness due to uniform shrinkage rate
• Natural block shade
• Convenient CAD/CAM System Integration

The average grain size of EVEREST after sintering for 2 hrs at 1,500°C: 0.3μm. The sintered density of EVEREST after sintering for 2 hrs at 1,500°C: > 99.85% theoretical density. EVEREST also promises uniform shrinkage rate due to CIP (Cold Isostatic Press) System treatment.

High compaction and uniform density allow for predictable shrinkage during the subsequent sintering process. The multi-layered EVEREST Zirconia is registered with systems from various well-known companies – eg. exocad, hyperDENT – for convenient and easy integration.

Founded in 2013, UNC International is a venture company included in the Korea Institute of Ceramic Engineering and Technology (KICET). It specializes in manufacturing Zirconia CAD/CAM blocks for the dental market.
