Ceramic-Based Hybrid Disk

Amber® Mill H Draws Attention

Amber® Mill H, a ceramic-based hybrid block developed and manufactured by HASS Co., Ltd., represents a significant advancement in the field of dental prosthetic materials.

Following the earlier release of the block-type product, HASS introduced a disk-type version in 2024, further expanding the Amber Mill H product lineup.

Originally available in C10, C12, and C14 sizes (5 blocks per pack), the newly introduced disk format now includes 8T and 10T sizes, broadening the product’s applicability for dental laboratories.

HASS offers a wide range of shades to meet the diverse needs of patients.
A total of 10 shades are available, including:

High Translucency (HT): A1, A2, A3, B1

Low Translucency (LT): W2, A1, A2, A3, A3.5, B1

This shade range enables restorations that blend naturally with patients’ existing dentition.

High Light Transmittance of Approximately 35%

One of the key advantages of Amber® Mill H is its fine crystalline ceramic particle base combined with a proprietary polymer bonding technology.

This innovative structure not only enables high initial bonding strength during resin cement light curing, 
but also improves indirect tensile strength to 75 MPa, helping reduce the risk of restoration debonding.

The material also demonstrates approximately 190 MPa of biaxial flexural strength and about 204 MPa of three-point flexural strength, contributing to reliable mechanical performance.

The Amber® Mill H Disk allows approximately 30–35 restorations to be nested and milled per disk, and it is compatible with both wet and dry milling processes.

For surface pretreatment of the restoration’s internal surface, users can choose between hydrofluoric acid etching or sandblasting, offering greater convenience and workflow efficiency.

Another notable feature of Amber® Mill H is its high light transmittance of approximately 35%, which supports strong initial bonding during cementation.

Additionally, the material exhibits natural opalescence and fluorescence, enabling highly esthetic restorations.

Thanks to precise milling performance and excellent marginal reproduction, 
Amber® Mill H demonstrates superior fitness gap performance, significantly improving the marginal fit between the tooth and the restoration.

A distinguishing characteristic of the material is its composition:
the combination of fine crystalline ceramic and polymer means it is classified as a hybrid ceramic, rather than a conventional hybrid resin.
