WHY ROSETTA SM
A Proven Lithium Disilicate Block for Everyday CAD/CAM Cases.
Rosetta SM has been part of the HASS portfolio for more than 13 years and is positioned as a stable, dependable lithium disilicate solution for clinics and laboratories that want predictable milling, crystallisation and esthetic results.
Milled at approximately 200 MPa before crystallisation for efficient CAD/CAM machining and margin control.
A long-established HASS lithium disilicate material with an extensive market history.
Select HT, LT, MT or MO according to the restoration and the amount of masking or translucency required.
STRENGTH PROFILE
Optimised for Milling First, Then Final Strength.
Rosetta SM is supplied in a pre-crystallised state for milling and develops its final mechanical properties after crystallisation.
Before Crystallisation200 MPa
After Crystallisation440 MPa
MachinabilityThe pre-crystallised state is designed to support efficient milling before final firing.
Final DurabilityThe recommended crystallisation cycle develops the final 440 MPa biaxial flexural strength reported by HASS.
Predictable FinishingAfter crystallisation, restorations can be polished or finished with stain-and-glaze according to the selected workflow and IFU.

WHICH HASS BLOCK?
Rosetta SM vs Amber Mill
Both are lithium disilicate CAD/CAM materials, but they are designed around different inventory and translucency strategies.
| Feature | Rosetta SM | Amber Mill |
|---|---|---|
| Positioning | Proven everyday lithium disilicate block with dedicated translucency families. | Premium HASS lithium disilicate with heat-treatment-based translucency control. |
| Translucency Strategy | Choose HT, LT, MT or MO before milling. | Use recommended heat-treatment protocols to achieve HT+, HT, MT, LT or MO from the Amber Mill material family. |
| Reported Final Strength | 440 MPa after crystallisation. | Approx. 450 MPa fully crystallised. |
| Best Fit | Routine crowns, veneers, inlays and onlays where straightforward selection and proven performance are priorities. | Cases where flexible translucency control and premium optical workflow are priorities. |
| Workflow Message | Select. Mill. Crystallise. Finish. | One block family. Multiple translucencies. |

FREQUENTLY ASKED QUESTIONS
Rosetta SM Workflow Questions
Does Rosetta SM require crystallisation after milling?
Yes. Rosetta SM is milled in its pre-crystallised state and then crystallised according to the current HASS Instructions for Use before final finishing and clinical delivery.
What is the difference between HT, LT, MT and MO?
They are separate translucency / opacity families. HT provides higher translucency, LT provides more masking, MT provides a medium-translucency option, and MO provides increased opacity for selected substrate conditions.
How is Rosetta SM different from Amber Mill?
Rosetta SM uses dedicated translucency families selected before milling. Amber Mill is designed around adjustable translucency through the manufacturer's recommended heat-treatment protocols.
Can DDA help confirm milling compatibility?
Yes. Contact Dental Dynamics Australia with your milling machine and block-holder setup and our team can help confirm the appropriate workflow and compatibility before use.
