I have a client with an 11 unit bridge.
hes keen on metal but i dont want to cast the thing.
I know traditionally i would have waxed a bar across the back of the arch of the bridge to keep it from warping then cut it off after i finished the porcelain work but do i need to give a milled CoCr frame the same type of support? I know its more rigid than gold alloy but i dont want to find out the hard way with this one.
cheers guys.
