Recommended Hot-Press Ceramic Workflow

  1. Create the Wax or Digital Pattern
    Produce the restoration pattern using conventional wax-up, a compatible 3D-printed burnout pattern, or a CAD/CAM-milled wax pattern.
  2. Attach the Sprues
    Connect the restoration pattern to the pressing channel using an appropriate sprue design that allows the softened glass ceramic to flow into the mold cavity.
  3. Invest the Pattern
    Place the sprued pattern into the investment ring and mix and pour the applicable investment material according to the investment-system instructions.
  4. Allow the investment material to set before burnout.
    The current laboratory workflow uses an approximate 30-minute setting period. Always follow the instructions of the selected investment system.
  5. Complete High-Temperature Burnout
    Burn out the wax or compatible pattern material to create the internal mold cavity that will reproduce the final restoration shape.
  6. Press the Lithium Disilicate Ingot
    Place the selected lithium disilicate ingot into the pressing system and complete the applicable product-specific hot-press cycle.
  7. Cool, Divest & Separate
    After pressing and appropriate cooling, remove the investment material, separate the restoration from the sprue system, inspect the pressed ceramic, and complete the required cleaning or sandblasting procedure.
  8. Remove the Reaction Layer & Finish
    Remove the surface reaction layer using the applicable finishing procedure, then complete grinding, polishing, characterization, or glazing according to the desired final restoration.

Pressing & Burnout Guidance

  • Investment Setting

    After the wax or digital pattern has been sprued and invested, allow sufficient time for the investment material to set before beginning the burnout cycle.

    The current laboratory workflow uses approximately 30 minutes. Follow the specific instructions of the investment system being used.

  • High-Temperature Burnout

    The burnout step removes the wax or burnout pattern and creates the cavity that determines the shape of the final restoration.

    Complete burnout is essential before pressing the lithium disilicate ceramic.

What is pressable lithium disilicate?

Pressable lithium disilicate is a dental glass ceramic processed through a lost-wax hot-press technique. A wax or compatible digital pattern is invested and burned out, and the heated ceramic ingot is then pressed into the resulting mold cavity.

What is the flexural strength of these ingots?

The current product specification is 470 MPa flexural strength when the material is processed according to the applicable pressing and finishing instructions.

What is the difference between HT and LT?

HT provides higher light transmission and is generally preferred when greater translucency is desired.

LT provides lower light transmission and more control over the influence of the underlying preparation.

Selection should consider preparation shade, restoration thickness, masking requirements, and desired final appearance.

Which restorations can be made with pressable lithium disilicate?

Typical laboratory applications include appropriate single crowns, veneers, inlays, onlays, and partial-coverage restorations.

Final indication should follow the applicable product documentation and restoration-design requirements.

Can I use a digital workflow with pressable lithium disilicate?

Yes. The restoration pattern may be designed digitally and produced using a compatible 3D-printed burnout pattern or CAD/CAM-milled wax pattern before investing and pressing.

What is the recommended pressing temperature?

The current recommended pressing workflow uses an approximate temperature of 910°C.

Always use the current product-specific pressing guidance and confirm the settings for your press furnace before processing.

Does the material require crystallization after pressing?

The current workflow is based on hot pressing followed by cooling, divesting, reaction-layer removal, finishing, characterization, polishing, or glazing as required.

A separate post-press crystallization step is not included in the current processing workflow provided for this product.

What is the difference between pressable ingots and lithium disilicate CAD/CAM blocks?

Pressable ingots use a pattern, investment, burnout, and hot-press workflow.

Lithium disilicate CAD/CAM blocks are digitally milled and then require post-milling crystallization.

The better option depends on your laboratory equipment, preferred workflow, and restoration requirements.

Which press furnace can I use?

Compatibility depends on the furnace's press-ceramic capability and available program settings.
