Hi Bex, sorry I was away on a business trip and got not time to be on the forum. I communicated with DRM Labs from CT and they r the manufacturers of DiamondLite, DiamondBond and the whole Diamond family, and they gave me convincing evidence about their products, so I guess I will go with it. I just have to find a dentist willing to use it... if u want I can share it with u...

I am sure tetra Ceram is also a Biocompatible material as it's quite famous among biological dentists...
