If larger parts are to be electroformed (3-part, 4-part
splints, bridges etc.), these can be contacted using
several AGC
are added together.
Typical calculation:
¬ 3-part splint (e.g. 2 anterior teeth, 1 premolar),
electroforming thickness: 0.2 mm
‹ 86 ml (level 7) + 37 ml (level 4) = 123 ml
Calculating the capacity required:
The capacity is determined on the basis of the calcu-
lated quantity of gold electrolyte and the brightener
additive required (4 ml per contact). The amounts
stated must be treated as minimum capacities, even if
the required amount of gold electrolyte is less!
Provided that the capacity is adequate, always use the
larger beaker. The number of crown copings given in
brackets for the 250 ml beaker therefore refers only to
those capacities which cannot be used in the 600 ml
beaker.
