When it comes to high-end restorations, HASS BIO has set a new global standard. But which block should you choose for your daily workflow? Let’s dive into the technical differences between the legendary Amber Mill and the innovative Amber Mill Direct.
1. Amber® Mill: The Freedom of Translucency
The world’s first lithium disilicate block with controllable translucency.
The Tech: Through specialized heat treatment, you can decide the translucency level (HT, MT, LT, or MO) using a single block.
The Benefit: One stock fits all. You achieve a dense, nano-crystalline structure that ensures superior marginal integrity (no chipping) and a flexural strength of 450 MPa after firing.
Best for: Lab technicians who demand absolute control over the optical properties for highly aesthetic, customized cases.
2. Amber® Mill Direct: Efficiency Without Compromise
The next generation of Chairside CAD/CAM materials.
The Tech: This is a pre-crystallized lithium disilicate. It does not require a firing process to achieve its final strength.
The Benefit: Significant time savings (minus 20-30 minutes of furnace time). It features a natural translucency gradient from the incisal to the cervical area, providing life-like aesthetics right out of the milling machine.
Best for: Clinics and labs focused on "Same-Day Dentistry" and maximum productivity without sacrificing the 450 MPa durability.
Summary Comparison:
Firing: Amber Mill (Required) vs. Amber Mill Direct (Not Required).
Customization: Amber Mill offers adjustable translucency via temperature.
Workflow: Amber Mill Direct is optimized for speed and immediate glazing/polishing.

Feature | Amber® Mill | Amber® Mill Direct |
Material State | Partially Crystallized (Purple/Blue) | Fully Crystallized |
Crystallization Firing | Required | Not Required |
Flexural Strength | ~450 MPa (Post-firing) | ~450 MPa (Immediate) |
Translucency Control | Adjustable via Temperature | Pre-set Gradient |
Amber® Mill Translucency Guide (Target Temperatures):
Specific translucency is achieved by reaching the following peak temperatures in a vacuum furnace:
Target Translucency | Peak Temperature (Approx.) | Resulting Aesthetic | |
HT (High Translucency) | 815°C | Ideal for inlays, onlays, and veneers | |
MT (Medium Translucency) | 830°C | Perfect for posterior crowns and bridges | |
LT (Low Translucency) | 845°C | Great for high-value teeth and masking | |
MO (Medium Opacity) | 860°C | Best for abutments or slightly discolored stumps |
> Note: Results may vary slightly depending on the furnace brand. Always calibrate your equipment for optimal results.
