ST-ML Dental Zirconia Blank with super translucent multilayer technology delivers exceptional esthetic precision for modern dental restorations. Featuring multiple pre-determined layers with high translucency, this multilayer zirconia disc accurately replicates the natural tooth shade and texture, offering lifelike color transitions without additional staining, simplifying workflow for esthetic anterior crowns, posterior crowns, veneers, and multi-unit zirconia bridges. Combined with advanced CAD/CAM milling, the ST-ML block ensures a seamless fit, reliable mechanical strength, and superior surface quality, creating prosthetics that blend naturally with surrounding teeth.
Translucency: 42% - 46%
Strength: >800 Mpa

As a representative of 2D zirconia products, this block is recognized as a cost-effective champion, combining affordability with outstanding mechanical performance.
>800 MPa, ensuring outstanding flexural strength for various dental restorations.
Utilising advanced multi-layer pre-staining technology, this product features rich colour gradients, enabling the achievement of the desired aesthetic result without the need for additional staining, thereby enhancing efficiency in dental laboratories.
Manufactured using high-quality zirconia powder from reputable publicly traded companies, ensuring material consistency, stability, and predictable CAD/CAM milling performance.
Achieving 42%-46% translucency through advanced multi-layer pre-staining technology, it delivers lifelike shading and natural tooth appearance without additional coloring.
Possessing an ultra-high flexural strength gradient, it is suitable for diverse dental restoration needs, including single crowns or three-unit bridges, as well as applications like zirconia bridges with more than 4 units, copying, implant abutments, and full arch.
With over 1 million units sold worldwide from the same high-quality raw materials, it demonstrates market trust, reliability, and consistent performance.
