Z-Star 4D PRO – Multilayer Zirconia Block
The Z-STAR 4D PRO Zirconia Block is a multilayer zirconia disc that combines high strength with lifelike esthetics.
With flexural strength of up to 1250 MPa, it ensures stability for long-span bridges and posterior restorations, while translucency of up to 57% allows seamless integration in anterior cases.
The block’s natural colour gradient delivers smooth, realistic transitions across all layers, reducing the need for additional shading. A single disc supports a full range of restorations—from veneers and crowns to implant-supported full arches.
