SPECIFICATION LEGEND

Explanation of abbreviations and numbering:

x = content < 0.1 mass%

Indications:

1 Inlays, cervical filling
2 MOD Inlays
3 Crowns
4 Bridges
5 Milling technique
6 Partial dentures
10 Cast posts
14 Can be veneered with high expansion, low-fusing ceramics
15 Implant restorations
16 Electroformed double crown technique (primary crowns)

Abbreviations:

w = after soft annealing and quenching
k = ceramic bonding alloy: condition after ceramic firing
v = after hardening
s = self-hardening after slow cooling in the mould

A = A stable framework design with reinforced connections with a cross section of 8 – 10 mm² is required for long span bridges and superstructures. Additionally, the frameworks need to be hardened.
B = Depending on the copper content, in some cases discolouration ofdouble crowns may result after short period of wearing. Discolouration, however, is technically and physiologically harmless.
C = In exceptional cases these alloys can also be used for traditional telescopic crowns with parallel walls and for the bar casting technique provided that cross-sections for crown walls, approximal areas, bars and laser welded joints are particularly thick and the alloy is hardened subsequently. No indication for conical crowns and sheardistributors.
