  • Approx. 420 MPa Strength

    Lithium disilicate combines reliable flexural strength with the esthetic properties of a glass ceramic, making it a versatile option for appropriate single-unit restorative workflows.

  • Natural Esthetic Potential

    The glass ceramic structure supports natural light transmission and optical depth for laboratories producing esthetic anterior and posterior restorations.

  • HT & LT Options

    Choose between High Translucency and Low Translucency options according to restoration thickness, preparation color, masking requirements, and desired esthetic result.

  • Predictable CAD/CAM Workflow

    A structured mill-and-crystallize workflow allows laboratories to combine digital design and machining with controlled ceramic firing and final characterization.

HT vs. LT: Choose the Right Translucency

Select translucency according to the preparation, restoration thickness, optical requirements, and desired final appearance.

  • HT – High Translucency

    HT provides greater light transmission and is designed for cases where a more translucent and natural optical effect is preferred.

    Consider HT for restorations where the underlying preparation color is suitable and higher translucency supports the desired esthetic result.

    Typical considerations:

    • Higher light transmission
    • Natural optical appearance
    • Esthetic-focused restorative workflows
    • Selected veneers, inlays, onlays, and crowns

  • LT – Low Translucency

    LT provides lower light transmission than HT and offers greater control over the influence of the underlying preparation.

    Consider LT when additional masking or greater shade control is required while maintaining the esthetic characteristics of lithium disilicate.

    Typical considerations:

    • Greater masking capability than HT
    • More controlled underlying color influence
    • Versatile crown workflows
    • Esthetic restorations requiring additional opacity

Recommended Applications

Designed for esthetic single-unit restorations where a combination of glass ceramic esthetics and reliable strength is required.

OnePro Dental Lithium Disilicate CAD/CAM Blocks can be considered for a range of appropriate single-unit restorative applications, including:

  • Anterior single crowns
  • Posterior single crowns
  • Veneers
  • Inlays
  • Onlays

  • Other esthetic single-unit CAD/CAM restorations supported by the applicable product instructions

Lithium disilicate is particularly useful when the restoration requires more natural light transmission than highly opaque restorative materials while still providing reliable mechanical performance.

Important Note:Final indication should always be determined according to the applicable product documentation, restoration design, preparation, material thickness, occlusal conditions, and professional clinical assessment.
For high-load, long-span, or multi-unit cases, evaluate whether a higher-strength zirconia material may be more appropriate.

20 Shade Options with HT & LT Translucency

Choose the appropriate shade and translucency according to the restoration design and desired final esthetic result.

Shade Group Available Shades
A Shades A1, A2, A3, A3.5, A4
B Shades B1, B2, B3, B4
C Shades C1, C2, C3, C4
D Shades D2, D3, D4

Note

Final restoration appearance depends on multiple factors, including block shade, translucency, restoration thickness, preparation color, crystallization, characterization, glazing, polishing, and the selected bonding or cementation system.

For demanding esthetic cases, evaluate these factors together rather than selecting the block by shade alone.

Post-milling crystallization is an essential step for developing the final properties, shade, translucency, and appearance of the lithium disilicate restoration.

OnePro Dental Lithium Disilicate CAD/CAM Blocks are supplied for a mill-and-crystallize workflow.

After milling and preliminary finishing, the restoration must complete the applicable crystallization cycle in a compatible ceramic furnace before final use.

During crystallization, always consider:

  • The current product-specific firing program
  • Ceramic furnace calibration and condition
  • Starting and final temperatures
  • Heating rates
  • Holding times
  • Vacuum requirements when applicable
  • Restoration design and thickness
  • Staining or glazing materials used during the firing workflow

Do not assume that a firing program used for another lithium disilicate brand or glass ceramic product is automatically suitable for this material.
