HASS · LITHIUM DISILICATE PRESS INGOT
Strong Foundation.
Layered Esthetics.
Amber Press is a lithium disilicate press ingot developed for stable pressing, high esthetics and efficient laboratory processing. Its crystallised cross-linked microstructure supports thin margins, reduced chipping and minimal reaction layer after pressing. The MO range is designed for frameworks and restorations where increased masking and a layered ceramic workflow are required.

WHY AMBER PRESS
Designed for the Press Lab.
Amber Press combines the familiar lost-wax pressing technique with a lithium disilicate material engineered for strength, edge stability and cleaner post-press processing.
Minimal Reaction Layer
Amber Press is engineered to leave very little reaction layer after pressing, simplifying divesting and post-press clean-up.
Natural Esthetics
Multiple translucency and opacity options support staining, cut-back and layering approaches across a broad range of restorative cases.
SELECTED TRANSLUCENCY
MO · Built for Masking and Layering.
MO
Medium Opacity
MO is the framework-oriented option in the Amber Press family. Use it when control of the underlying substrate is important and the final esthetics will be developed with veneering ceramic.
Layering-OrientedHASS positions MO for layering workflows rather than primarily stain-only finishing.
Control the SubstrateMedium opacity helps reduce the visual influence of the underlying preparation or framework where additional masking is required.
Build Final EstheticsUse compatible veneering ceramic to develop morphology, depth and optical character over the pressed framework.

CLEANER POST-PRESS PROCESSING
Less Reaction Layer. Less Clean-Up.
One of Amber Press's strongest laboratory advantages is what happens after pressing.
Minimal Reaction Layer
HASS states that Amber Press leaves only a small amount of reaction layer after pressing, helping simplify post-press processing and reduce unnecessary adjustment.
No Acid Liquid Required
According to HASS, acid liquid is not required for reaction-layer clean-up in the recommended Amber Press workflow, supporting a simpler and less hazardous laboratory process.
VENEERING FLEXIBILITY
Work With Familiar Ceramic Systems.
Amber Press is compatible with a range of veneering materials intended for lithium disilicate restorations. HASS also publishes specific guidance for selected zirconia veneering porcelains when used with Amber Press.

PRESS OR MILL?
Amber Press vs Amber Mill
Both use HASS lithium disilicate technology, but the production workflow is fundamentally different.
| Feature | Amber Press | Amber Mill |
|---|---|---|
| Manufacturing Method | Lost-wax press technique | CAD/CAM milling |
| Best Fit | Laboratories using wax-up, investment and ceramic pressing workflows | Digital CAD/CAM laboratories and clinics |
| Reported Strength | 460 MPa biaxial flexural strength | Approx. 450 MPa fully crystallised |
| Optical Selection | Dedicated HT, LT and MO ingot families | Heat-treatment-based translucency control across HT+, HT, MT, LT and MO |
| Finishing Approach | MO: layering-oriented | Crystallisation followed by polish, stain and/or glaze according to the selected protocol |
| Key Workflow Advantage | Minimal reaction layer and no acid clean-up requirement in the recommended workflow | Digital design, milling and adjustable translucency |

FREQUENTLY ASKED QUESTIONS
Amber Press Workflow Questions
What is the difference between Amber Press HT, LT and MO?
HT is the more translucent option, LT provides increased masking, and MO is the more opaque framework-oriented option. HASS positions HT and LT primarily for staining / cut-back workflows and MO for layering.
Does Amber Press require acid reaction-layer removal?
HASS states that Amber Press produces only a small reaction layer and does not require acid liquid for clean-up when processed according to the recommended workflow.
Can Amber Press be layered with veneering ceramic?
Yes. HASS documents compatibility with multiple veneering systems. Always confirm the current HASS guideline and the veneering ceramic manufacturer's instructions before use.
Is Amber Press the same material as Amber Mill?
They are both lithium disilicate-based HASS restorative materials, but Amber Press is processed by the lost-wax press technique, while Amber Mill is a CAD/CAM material designed for milling and subsequent crystallisation.
