economical,  non-gamma 2,  admix alloy

The technically advanced, non-gamma 2 admix amalgam at an affordable price.

GS-80's high strength and positive dimensional change ensures longevity and patient satisfaction.

Over 200 million successful GS-80 restorations have been placed since its release worldwide in 1986.

Optimal handling characteristics
GS-80's consistent mix, ease of loading, placement in preparations, condensability, burnishability, quality of interproximal contact, carvability, and setting characteristics ensure the final restorations meet the needs of the operator.


High compressive strength
GS-80's high compressive strength minimizes the risk of fracturing the restoration.(1) High compressive strength ensures a tough and durable long lasting restoration.


Capsule system
The SDI capsule system is designed to give consistent and accurate mixes every mix. 





Positive dimensional change
GS-80's positive dimensional change ensures excellent sealing qualities at the margins.(1) Negative values can contribute to post operative sensitivity.


Greater choice of setting times and larger choice of capsule sizes
The working and setting times allow large restorations to be condensed and carved without difficulty.


Ultramat 2
The dual voltage Ultramat 2 with a high precision microprocessor controlled timer provides consistent and accurate trituration, ensuring the optimal handling and clinical characteristics of mixed materials.
