Official Dental Dynamics Australia Product
Z-STAR D-MAX 4D PRO — Strength Meets Aesthetics
Z-STAR D-MAX 4D PRO, carefully selected by Dental Dynamics Australia for dental labs across Australia and New Zealand, is a multilayer zirconia block that achieves 650–1,250 MPa flexural strength and 43–57% translucency simultaneously. It holds all three major international certifications: CE0197, ISO13485 and FDA.
650–1,250 MPa Gradient Strength
A continuous strength gradient from 650 MPa at the incisal edge to 1,250 MPa at the cervical region — suited to bridges and implant crowns alike.
43–57% Translucency Gradient
4D PRO layer technology recreates the natural enamel-to-dentin transition within a single block, minimising the need for additional colouring.
Triple International Certification
Holds CE0197, ISO13485 and FDA certification, and meets Australia's TGA requirements — giving labs confidence for clinical use.
Open CAD/CAM System
Fully compatible with major 98mm-format milling systems including Roland, VHF, Amann Girrbach and Wieland.
LUNAR Stain & Glaze Clinical Cases
Z-STAR + LUNAR — Aesthetics Indistinguishable from Natural Teeth
These clinical cases were created by internationally renowned master dental technician Katsuya Sato, using LUNAR Stain & Glaze on Z-STAR zirconia. By combining LUNAR stains — Dark Brown, Purple Blue, Orange, Shade A, Black, Grey and White — he achieved a gradient nearly indistinguishable from natural dentition.
Anterior Case — Stain Colour Guide
Dark Brown + Purple Blue + Orange (cervical) → Shade A (mid) → Black 50 + Grey 50 (incisal) + White. Natural cervical chroma with incisal translucency.
4-Unit Anterior — Full Colouring Guide
Shade A + Orange (cervical) → Black 20 + Grey 80 (mid crack line) → Light Grey + Shade A + White (incisal). A uniform, natural ensemble.
Materials Science
Core Zirconia Properties — Why Z-STAR's Numbers Matter
Zirconia's clinical performance is determined by sintering temperature, yttria content and powder purity. Z-STAR D-MAX 4D PRO optimises all three variables to achieve strength and aesthetics simultaneously.
| Property | Z-STAR Value | Clinical Significance |
|---|---|---|
| Flexural Strength | 650–1,250 MPa (by layer) | Suitable range for single crowns, bridges and implant restorations |
| Translucency | 43–57% | Achieves light transmission comparable to natural anterior teeth |
| Density (post-sintering) | ≥ 6.0 g/cm³ | High density minimises micro-cracking |
| Sintering Temperature | 1,530 °C | Within the optimal strength/translucency range, with strong energy efficiency |
| Layer Configuration | 4D PRO Multilayer | Recreates the natural enamel/dentin layer structure |
| CAD/CAM Format | 98mm (Open System) | Universally compatible with major milling systems |
| Certification | CE0197 · ISO13485 · FDA | Meets the highest international quality and safety standards |

Final Verdict
6 Reasons Z-STAR Is the Best Choice for Australian Dental Labs
✦ Z-STAR D-MAX 4D PRO — The Uncompromising Choice
- No compromise on strength: At up to 1,250 MPa, it surpasses Germany's Ivoclar (1,100 MPa) and Japan's KATANA (1,100 MPa). The 4D PRO layer structure covers every case, anterior to posterior, with a single product.
- No compromise on colour: A 43–57% translucency gradient plus VITA 16 shades. Combined with LUNAR Stain & Glaze, it achieves aesthetic results equal to or better than German and Japanese products.
- No compromise on sintering stability: Sintered at 1,530 °C, within the scientifically validated optimal range — minimising the risk of strength loss and reduced translucency from over-firing.
- No compromise on certification: Holds triple certification — CE0197, ISO13485 and FDA — and meets Australia's TGA requirements, ensuring far greater quality and safety assurance than low-cost Chinese alternatives.
- A decisive price advantage: 30–50% more affordable than German and Japanese equivalents. Unlike Chinese products, it comes with both quality certification and local technical support.
- Full local support in Australia: Backed by Dental Dynamics Australia's direct supply network. In partnership with ARUM Milling Centre, we support sintering parameter optimisation, technical training and fast delivery.
