AT Multilayer

The ICERA AT Multilayer is a revolutionary dental zirconia block purpose-built for anterior cosmetic restorations. As the most aesthetic disc in the ICERA zirconia family, the AT Multilayer breaks the limitations of traditional zirconia ceramics through advanced manufacturing technology and ultra-pure raw materials — delivering the lifelike translucency, natural fluorescence, and flawless shade transitions that anterior cases demand. Every restoration milled from the AT Multilayer integrates seamlessly with natural dentition, giving patients the bright, natural, beautiful smile they expect.

The AT Multilayer is a pre-shaded ultra-translucent multilayer zirconia disc designed exclusively for high-aesthetic anterior indications. Unlike conventional multilayer zirconia where color changes can appear as visible bands, the AT Multilayer features a continuous, gradient-free transition between layers — producing veneers and crowns that look indistinguishable from natural teeth. With 49% translucency, the AT Multilayer captures the translucent qualities of natural enamel while still providing more than 700 MPa of flexural strength to ensure long-term clinical reliability.

1. Ultra-High 49% Translucency The AT Multilayer achieves the highest translucency in the ICERA family, replicating the optical behavior of natural enamel. Light passes through the restoration with the same vitality and depth seen in natural teeth, making it the ideal choice for the most demanding cosmetic cases.
2. Seamless, Gradient-Free Layer Transitions Through proprietary multi-layer color infiltration technology, the AT Multilayer eliminates visible banding or stripe effects. Color, chroma, and translucency flow continuously from cervical to incisal, ensuring restorations appear as a single, organic structure.
3. Excellent Abutment Masking Despite its high translucency, the AT Multilayer offers surprisingly effective masking of underlying tooth structures, making it suitable for veneers placed over slightly discolored abutments — a clinical scenario where many high-translucency materials fail.
4. 1.5-Hour Rapid Sintering The AT Multilayer supports a fast 1.5-hour sintering cycle, enabling same-day restorations and dramatically improving lab throughput. Combined with chairside CAD/CAM workflows, this opens the door to true single-visit veneer treatments.
5. Natural Fluorescence and Vitality Carefully balanced material composition delivers fluorescence and chroma effects that match natural teeth under both daylight and artificial lighting — a critical factor for the visible smile zone.
6. Simple, Stable, Efficient Operation The AT Multilayer is engineered for predictable, repeatable performance. Technicians benefit from consistent milling behavior, stable sintering shrinkage, and minimal need for post-mill characterization.
7. Six Popular Anterior Shades Available in A1, A2, A3, B1, B2, and OM2, the AT Multilayer covers the most-requested shades for anterior aesthetic cases — perfectly aligned with veneer treatment planning.
8. Biocompatible & Patient-Safe Manufactured from certified high-purity zirconia powder, the AT Multilayer meets ISO 13356 biocompatibility standards and is fully safe for long-term intraoral use.

The ICERA AT Multilayer is purpose-built for high-aesthetic anterior restorations:
・Laminate veneers - ultra-thin restorations with lifelike translucency
・Anterior single crowns - maximum optical realism in the smile zone
・Anterior 2-to-2 bridges - including bridges with one missing tooth (one pontic)
・Cosmetic smile design cases
・Tooth whitening enhancement restorations
・Diastema closure veneers
・Minor anterior shape and alignment corrections
Note: Due to its aesthetic-focused strength profile (>700 MPa), the AT Multilayer is not recommended for posterior load-bearing restorations or long-span bridges. For those indications, consider ICERA 4D Pro Multilayer, 3D Pro Multilayer, or HT White.

The AT Multilayer represents the pinnacle of ICERA's commitment to anterior aesthetic excellence. Manufactured with Sinocera raw zirconia powders, every disc is produced through high-pressure cold isostatic pressing (CIP), precision pre-sintering, and proprietary ultra-translucent layering technology. Each batch undergoes rigorous quality inspection covering flexural strength, translucency, fluorescence, and shade accuracy — guaranteeing that every disc lives up to the demands of cosmetic dentistry.

For dental laboratories and clinicians who specialize in anterior cosmetic work, the AT Multilayer offers the rare combination of true enamel-like translucency, gradient-free shade beauty, abutment masking, rapid sintering, and reliable clinical strength — all in a single disc.
