Got the temporary crown on now - theyve sent the mould to the lab to manufacture a porcelain crown. This is the first Ive heard of zirconium crowns. I take it theyre not available on the NHS? Do they really eliminate the grey "margin"? Is £400 the price for a zirconium crown? Im tempted...
I had never heard of Zirconium Crowns before either. I had heard of the term Zirconium/zirconia which are a man made diamond.
Zirconia is a very tough ceramic material, which can be made incredibly thin.
These types of crowns contain no metal and can be made to look opaque or translucent, depending on your needs. If the zirconia crown is bonded onto the teeth rather than cemented with dental cement, it will not show a black line at the gums the way a porcelain-fused-to-metal crown can.
As for UK availability - then I dont know, not the price.
Out here a normal crown is £190, a porcelin £240 & a zirconia £290.
It could all just be a gimmic tho!
