Sorry I have another issue need to ask, I also have to change two crowns before get permanent denture fit because my gum line exposed due to shrinkage after extraction. Personally I want to change for Emax ceramic crowns. Previously I had zirconia crowns,which I feel too bulky,and people keep saying they are expose a little radioactive risk.

I'm not sure if Emax crowns are safe and biocompatible ones. I would be very appreciated to hear anybody can share any suggestion regarding this.
