I did a 77% FCG molar that had 200.00 in metal plus I charge 80.00 for the work.
These big labs cant be loosing money on each FCG crown they make can they?
I hate doing these restorations, contacts are such a bitch.
CONTACT PROBLEMS ON GOLD
Thought I would pass this tip to those that have contact problems with their gold crowns.....Wax contacts correctly in the wax,then use Renferts Waxfinish, I paint on 3 layers on the mesial and distal contacts.. Follow the directions with this product.......3 layers will give you a very snug contact. Polish gold contact very lightly, don't try to polish perfect ! May want to use 2 layers of Waxfinish.....
If you loose a contact, solder over a bunsen burner, if you still use one. Use a low fusing solder, I use 585, don't use 615 . Takes less than a minute . Pencil above the margin if you are new to soldering...
Dust off the polished area on the contact with a stone etc, put a touch of flux on the contact, cut a small piece of solder slightly larger than the contact then place on the contact, then wave back and forth over the flame. Just before the solder flows, leave in the flame until it flows, just for a second....NO more !
If you need to resolder, grind off the dark oxide so the solder will flow again ......
If your doctors are bitching about the high cost of gold, use a White (silver)colored type 3 "Noble" alloy that many companies have been selling for 30 + years. No worries about discoloring......
The one I use is a Argen product that has 2% gold, 25 pd, 68 ag, copper free.
Grinds and polishes like gold, with a very low price......
