Model number： SST-CTML

    SST-CTML – Ultra-Translucent Multilayer Zirconia (Natural Layered Shade Series)

    Product Description

    Structural Design:
    4Y–6Y graduated structure for biomimetic light performance
    SST-CTML features a high-translucency structure composed of a gradient from 4Y to 6Y-TZP. The cervical zone retains a high-content 4Y composition for structural strength, while the incisal zone incorporates a higher proportion of 6Y to enhance translucency and natural light diffusion.
    This design combines mechanical stability with a lifelike appearance, making it ideal for esthetic zones with moderate functional load.

    With translucency ranging from 45–49% and flexural strength between 800–1100 MPa, SST-CTML strikes the perfect balance between beauty and strength for restorative cases with both functional and esthetic demands.

    Indications:
    Anterior/posterior single crowns, short to medium-span bridges, smile design, and morphological refinements

    Key Features:
    • Multilayer gradient of 4Y–6Y structure for both support and optical realism
    • Soft, natural shade transitions with lifelike enamel-dentin mimicry
    • A versatile solution for esthetic-driven yet functionally stable restorations
