    ST White – Unshaded, High-Strength Zirconia

    Product Description

    Structural Design:
    Pure 4Y-TZP composition with an unshaded design, maximizing flexibility in processing and customization.

    ST White utilizes unshaded 4Y zirconia with a flexural strength exceeding 1100 MPa, specifically engineered for dental technicians who require special staining, porcelain layering, or individualized aesthetic treatments. The material offers excellent stability and consistent shrinkage behavior.

    Thanks to its uncolored base, ST White provides greater design freedom, making it ideal for long-span bridges or full-arch fixed restorations where precise color control or unique design is essential.

    Indications:
    Full-arch fixed prostheses, long-span bridges, custom-shaded or layered ceramic restorations

    Key Features:
    Unshaded design for personalized staining and ceramic application
    High strength and outstanding stability for demanding clinical needs
