Model number： ST-CML

    ST-CML – High-Strength Multilayer Zirconia

    Product Description

    Structural Design:
    Composed entirely of 4 mol% yttria-stabilized zirconia (4Y-TZP)
    The ST-CML series uses a single, stable 4Y-TZP composition, offering a flexural strength of up to 1100 MPa and approximately 45% translucency.
    It is specifically engineered for full-arch reconstructions and long-span bridges where strength and stability are critical.
    This zirconia features a natural multilayer gradient, delivering tooth-like esthetics without the need for porcelain layering, achieving both beauty and durability.

    Indications:
    Posterior crowns, multi-unit long-span bridges, full-arch fixed prostheses, and other high-load clinical applications

    Key Features:
    • Highest strength and structural stability in the series
    • Designed for demanding restorative cases
    • Natural gradient shading without the need for veneering porcelain
    • Balances functional reliability with aesthetic performance
