EC DCRC

TopCEM is a versatile and ultimate dental dual-cure luting resin cement, capable of both chemical and light cure.

Indication
Cementation of all sorts of dental restorations including crowns, bridges, inlays/onlays, veneers, dental posts and other restorations made from materials of metals/alloys, mental-ceramic, all-ceramic and/or porcelain, composites, and their combinations.

Advantages
* Dual cure offers flexible options:

Suitable for both dual cure and light cure.

* Sufficient working time and fast setting time:

Sufficient work time: leave enough time for doctors to prepare before they put everything into the patient's mouth.

Short curing time: avoid any unexpected movement or shift of the restoration after doctors have placed it into the patient's mouth.

* High flexural strength:

After curing it shows excellent physical and mechanical properties. Indicators such as flexural strength, film thickness, solubility and water absorption are better than most mainstream products in the market.

* Low film thickness, solubility and water absorption

* 3 opacity and 7 shades available:

With 3 opacity and 7 shades, satisfies the needs of both high translucency and shades covering, suitable for cementation of restorations with different color requirements.

* Impressive radiopacity, X-ray radiation resistance could be over 400%.
