Hello. My PFM crown on a first molar has cracked to the point where food traps between my teeth. I am going to request a full cast crown from my dentist. I heard that nonprecious is very hard to polish, so is it reasonable to ask for ask for semiprecious? Also, if a dentist were to ask to for a full cast crown for the same price as a PFM crown, what alloy would you use?

77% gold for full cast crown. Why no have a monolithic zirconia crown made?

I don't know what a dentist charges in your area.If it's about money then go with full contour zirconia crown.

You said, " a full cast for the same price as a pfm".

Whats your guess on the price of either? Which one do you think costs more?

PFM including dentist labor costs $600. The price of full cast crown depends on the type of alloy used. That's why I am asking which type of full cast crown would cost the same as PFM. I guessing a semi precious full cast crown.

$600 for a pfm crown? Where do you live? It's more like twice that in the northeastern state I live in.
It would take an unusually light crown for me to be able to make a full cast crown, even with a 40% AU alloy, that was similar in cost to a PFM with a nobel alloy.

Have it milled from solid titanium. Any milling center could handle that.

Chrome-Cobalt polishes fine and is probably the cheapest crown if that is your goal. It's very hard and will not easily scratch, but is also hard on your opposing teeth. A softer alloy will be kind to your opposing teeth and the doc can close margins if needed. If you want zirconia and your doc's lab doesn't do it, ask them to send it to someone who does. Zr has very little for plaque to adhere to and is easy to clean.

This CrCo has been rolling around my bench for 2 years. Note how minor the scratches are. It would never be my first choice, but it is an acceptable choice.

Depending on the alloy (and I agree with the 77% suggestion, which is not cheap though) and size of the gold restoration, the full gold crowns are usually more expensive than my pfms.

Size matters... o_O

Are chrome-cobalt full cast crowns hard for lab techs to work with and polish? Also, can the dentists adjust the margins?

Yes and limited...

With what did you end up with, in the first round?

If you want something durable, easily polished and the ability for the dentist to adjust the margin, go with a full cast gold restoration. As long as the gold content is around 50%, you will be fine. However, if your first crown was a cast crown, too, I would make sure tho get the same alloy as in the first restoration! Occasionally, different alloys can play tricks in a patients mouth!

And on that 'margin adjust' thing, if your dentist preps and takes an impression, as he should, there is no need to 'adjust' the margin at the time of insertion.

You seem to be concerned about what goes into your mouth, as I would be too. So, make sure your dentist/technician uses quality materials, like a high noble gold alloy. It may cost you more, initially, but you will be served better in the long run.

I am glad you mentioned that, because my new crown will be opposing my old crown which is chrome! So I will definitely get chrome for the new crown.

Crowns are reasonably priced out here. My dentist offered porcelain, but I am insisting on full cast metal because I had a PFM crown break in the past.
