4D Pro Multilayer

The ICERA 4D Pro Multilayer represents the pinnacle of advanced multilayer zirconia technology — a premium 6-layer dental zirconia disc engineered with a four-dimensional gradient of color, translucency, chroma, and strength. Designed to perfectly mirror the optical and mechanical properties of natural teeth, the 4D Pro Multilayer transitions seamlessly from a translucent enamel-like incisal edge to a stronger, more opaque cervical base. The result: restorations that look natural in the smile zone and perform reliably under occlusal load — all from a single, intelligently designed disc.

The 4D Pro Multilayer features a sophisticated 6-layer gradient structure that mirrors the optical progression found in natural dentition. Translucency decreases gradually from 49% at the incisal edge to 46% at the cervical region, replicating the way real enamel and dentin interact with light. Simultaneously, flexural strength increases from 700 MPa at the incisal layer to 1100 MPa at the cervical base — providing gentle occlusal contact that protects opposing natural teeth, while delivering the structural integrity needed for long-span bridge work. This dual gradient is what makes the 4D Pro Multilayer one of the most versatile premium zirconia options available today. Unlike conventional single-shade zirconia, the 4D Pro Multilayer eliminates the need for extensive manual staining or layering, allowing technicians to produce high-aesthetic restorations directly from the milled framework. This dramatically reduces chairside and lab time while ensuring consistent, predictable results across every case.

1. Six-Layer Natural Color Gradient The 4D Pro Multilayer features 6 carefully blended color layers that mimic the cervical-to-incisal chroma reduction of natural teeth. Transitions are seamless — there are no visible color stripes or banding artifacts, even on the most aesthetic anterior cases.
2. Dual Gradient Technology — Translucency + Strength Translucency increases toward the incisal edge while strength increases toward the cervical region. This means clinicians enjoy:
・Lifelike enamel translucency in the smile zone
・Effective abutment masking at the cervical region
・Gentle occlusal contact that doesn't damage opposing natural teeth
・High cervical strength suitable for long-span bridge frameworks
3. Outstanding Material Density With a pre-sintering density above 3.0 g/cm³ and post-sintering density above 6.0 g/cm³, the 4D Pro Multilayer delivers a dense, pore-free microstructure — ensuring fracture resistance, color stability, and long-term clinical durability.
4. Excellent Aging Resistance After accelerated aging tests, monoclinic phase content remains below 10%, demonstrating excellent low-temperature degradation (LTD) resistance — a critical factor for long-term oral performance.
5. Outstanding Biocompatibility & Safety With Grade 0 cytotoxicity, radioactivity below 0.1 Bq/g, and chemical solubility below 100 μg/cm², the 4D Pro Multilayer is fully safe for permanent intraoral use, even in patients with sensitive tissues.
6. 27+ Shade Options Covering VITA 16 classical, VITA 26 expanded, and 5 bleach shades (OM2, BL1, BL2, BL3, BL4), the 4D Pro Multilayer satisfies virtually every clinical case — from natural shade matching to aggressive whitening cases.
7. Multiple Disc Sizes Available in 98mm, 95mm, and 92×75mm diameters with thicknesses from 12mm to 25mm, the 4D Pro Multilayer fits virtually every CAD/CAM system on the market.
8. CAD/CAM Optimized Uniform pre-sintered density ensures smooth, chip-free milling, sharp margin definition, extended bur life, and predictable sintering shrinkage for accurate restoration fit.

The ICERA 4D Pro Multilayer covers the broadest range of indications among aesthetic multilayer zirconia products:
・Anterior single crowns - maximum smile-zone aesthetics
・Posterior single crowns - full-contour durability
・Full-arch bridges - made possible by the high-strength cervical layer
・Half-arch bridges
・Screw-retained implant bridges
・Implant-supported single crowns
・Laminate veneers - with lifelike incisal translucency
・Inlays and onlays
・Cosmetic smile design cases

The 4D Pro Multilayer is the result of years of research in zirconia gradient technology, combining Sinocera raw materials with proprietary European-inspired manufacturing techniques. Every disc undergoes high-pressure cold isostatic pressing (CIP), controlled pre-sintering, and rigorous quality inspection to guarantee flexural strength, translucency, and shade consistency.

For dental laboratories seeking a zirconia material that delivers premium aesthetics without sacrificing strength — and without the price tag of imported European brands — the ICERA 4D Pro Multilayer is the intelligent choice. It empowers technicians to deliver restorations that satisfy the most demanding cosmetic cases while maintaining the mechanical reliability clinicians require.
