Zirconium dioxide dental material KATANA* Zirconia YML

ZrO2zirconiafor implant abutments

Overview
KATANA* Zirconia YML is a 4-layer, type-layer zirconia blank designed for dental restorations, offering a pigmented incisal layer for optimized translucency and consistent flexural strength across dentin and transfer areas. Suitable for monolithic and veneered solutions as well as implant abutments.

Key features

• Latest generation type-layer zirconia with patented raw material technology
• Consistently high flexural strength in dentin and transfer zones
• Optimized translucency with pigmented incisal layer for natural aesthetics
• 4-layer Multicolor structure with smooth layer transitions
• Available in 13 VITA classical shades (A–D)
• Multicolor format suitable for monolithic restorations and microveneering
• Supports bridge frameworks up to 14 units and up to two adjacent pontics
• Applicable for implant abutments, monolithic abutment crowns and bridges
