Crowns and bridges
remanium® secura
CoCr bonding alloy with maximum reliability potential during
processing. Excellent casting behavior, including vacuum
pressure casting.
Advantages:
• reliable melting and casting characteristics, especially
with vacuum/pressure casting, resulting from the narrow
melting range
• small ingots (4 g) allow exact dosage of the alloy:
ideal and economical filling of the crucible
• no danger of spattering or increased slagging
• high mechanical strength thanks to tantalum-based crystal
structure reinforcement
• enhanced firing behavior of the veneering ceramics
through low oxidation
• polished surface has a radiant lustre due to high chrome
content
Indication: crowns and bridges, metal ceramics, double
crowns, implant supported supra-structures, Maryland
