Z-STAR MULTILAYER ZIRCONIA
Strength Where You Need It.
Esthetics Where You Want It.
Z-STAR 4D PRO is a 5-layer 4D multilayer zirconia designed to combine natural esthetics in the incisal zone with progressively higher structural strength toward the cervical zone, supporting crowns, bridges, implant restorations and full-arch workflows.

REAL RESTORATIONS
Made for More Than Everyday Zirconia
From highly esthetic single units to implant-supported full-arch restorations, Z-STAR gives dental laboratories the flexibility to work across a broad range of indications.
Crowns & Bridges
A balance of strength and esthetics for predictable everyday restorative production.
Full-Arch Restorations
High-strength zirconia for demanding implant-supported and full-contour full-arch applications.
4D MULTILAYER TECHNOLOGY
Strength Meets Natural Translucency
The 5-layer 4D multilayer structure gradually increases strength from 650 MPa to 1250 MPa while translucency transitions from 57% to 43% from the incisal zone to the cervical zone.

Natural Shade Gradient
Smooth colour progression supports a natural appearance while reducing excessive manual characterisation.
Variable Translucency
Translucency progresses from 57% in the incisal zone to 43% in the cervical zone for a natural optical transition.
High-Strength Foundation
Strength progresses from 650 MPa in the incisal zone to 1250 MPa in the cervical zone for structural support.
One Versatile Material
Cover a broad range of restorative indications with one multilayer zirconia family.

FULL-ARCH PERFORMANCE
Built for Full-Arch Confidence.
Full-arch restorations require more than esthetics alone. Z-STAR 4D PRO combines a high-strength zirconia foundation with multilayer optical characteristics for demanding implant-supported restorations where strength, efficiency and appearance all matter.
