Ceramic + Polymer Structure
Fine crystalline ceramic particles are integrated with a polymer network through chemical cross-linking, targeting a balance of esthetics, strength and machinability.
HASS · CERAMIC-BASED HYBRID CAD/CAM BLOCK
Ceramic Performance.
Hybrid Efficiency.
Amber Mill H is a ceramic-based hybrid CAD/CAM material that combines fine crystalline ceramic particles with a polymer network through HASS cross-linking technology. It is designed for precise milling, reliable marginal reproduction and a streamlined restorative workflow without a crystallisation firing step.

WHY AMBER MILL H
A Hybrid That Starts With Ceramic.
Amber Mill H is not conventional lithium disilicate and it is not simply a resin composite block. HASS classifies it as a ceramic-based hybrid material, combining fine crystalline ceramic with a polymerized hybrid structure.
No Crystallisation Firing
Mill, finish and proceed to bonding without the additional crystallisation cycle required by conventional partially crystallised lithium disilicate.
Clean Milling & Margins
Designed for accurate CAD/CAM machining with reduced chipping and precise marginal reproduction for efficient restorative finishing.
OPTICAL PERFORMANCE
More Light Transmission for Efficient Bonding.
35%Light Transmittance · HT
HASS reports approximately 35% light transmission for Amber Mill H HT. Higher light transmission can support resin-cement light polymerisation and initial bonding while maintaining natural restorative esthetics.
HT · High TranslucencyAvailable in A1, A2, A3 and B1. Designed for cases where greater light transmission and vitality are desired.
LT · Low TranslucencyAvailable in W2, A1, A2, A3, A3.5 and B1. Provides more optical control and masking than HT.
Natural Optical BehaviourHASS describes controlled opacity, opalescence and fluorescence to help restorations integrate naturally with surrounding dentition.
MECHANICAL PERFORMANCE
Built for Everyday Restorative Stability.
Amber Mill H combines flexural strength, tensile resistance and milling stability to support a practical hybrid restorative workflow.
Reduced Chipping
HASS highlights the material's milling performance and edge stability as a key advantage, helping technicians and clinicians achieve cleaner margins during fabrication.
Strong Initial Retention
Manufacturer testing reports 75.2 MPa indirect tensile strength, a property HASS associates with improved resistance to restoration dislodgement.
INDICATIONS
For Conservative Everyday Restorations.
Use Amber Mill H according to the current HASS Instructions for Use, preparation design and minimum-thickness requirements.

CEMENTATION FLEXIBILITY
Two Internal Surface Pretreatment Options.
Unlike many hybrid blocks that are associated mainly with airborne-particle abrasion, HASS documents both hydrofluoric-acid etching and sandblasting as pretreatment approaches for Amber Mill H.
Option 1
Hydrofluoric Acid Etching
- Etch the internal surface with 5% HF for 60 seconds.
- Rinse thoroughly and air dry.
- Apply silane and air dry for approximately 20 seconds.
- Use the appropriate resin cement / bonding system according to the manufacturer's instructions.
Option 2
Sandblasting
- Air abrade with 25–50 μm alumina at approximately 2 bar.
- Clean with ethanol or an ultrasonic cleaner and dry thoroughly.
- Apply silane and air dry for approximately 20 seconds.
- Use the appropriate resin cement / bonding system according to the manufacturer's instructions.
Do not over-etch. Always follow the current HASS IFU and the cement / bonding manufacturer's instructions for clinical use.
NO CRYSTALLISATION
A Faster Route From Milling to Delivery.
Amber Mill H removes the crystallisation step from the conventional lithium-disilicate workflow. For laboratories and clinics focused on efficient single-unit production, that means fewer furnace-dependent steps and a more direct path from CAD/CAM manufacturing to final finishing and bonding.

FREQUENTLY ASKED QUESTIONS
Amber Mill H Questions
Is Amber Mill H lithium disilicate?
No. Amber Mill H is a ceramic-based hybrid CAD/CAM material. It combines fine crystalline ceramic particles with a polymerized hybrid structure. Amber Mill, without the “H”, is HASS's conventional lithium disilicate CAD/CAM material.
Does Amber Mill H need crystallisation?
No additional crystallisation firing is required. After milling, the restoration can proceed to finishing, surface pretreatment and bonding according to the current HASS workflow.
What is the difference between HT and LT?
HT provides greater translucency and light transmission; LT provides additional optical control and masking. The current DDA product offers HT in A1, A2, A3 and B1, and LT in W2, A1, A2, A3, A3.5 and B1.
Can Amber Mill H be acid etched?
Yes. HASS documents both hydrofluoric-acid etching and sandblasting as internal-surface pretreatment options. Follow the current HASS IFU and your bonding-system manufacturer's instructions.
