Hi Rachie, the australian test will probably be just as good. Gradia is not a composite as such, I looked on my serum testing form and it's under the title of ceramic.

Usually these are pretty biocompatible with most people. Russ is concerned about the aluminium and I was too with the one I'm probably getting. But the form of aluminium in these materials is aluminium oxide, which is pretty bio inert. It actually isn't a metal anymore, because it has been altered into a form that is no longer metallic. Aluminium oxide (alumina) is found just about anywhere. Baking powder, and will be in vegetables due to the soil they grow in. WE pick it up anywhere. Walter Clifford told me that they are very very concerned about aluminium, but he said they take NO notice of aluminium oxide in dental materials, even for those allergic to aluminium. It is not in a form that is bioavailable and as he told me, you'd get more from diet alone that you would with a full set of ceramic dental materials in a lifetime. How true this is? I do not know, but you're hearing from someone with a biochemistry degree, so he must know what he's talking about.

He told me that every single dental materials contains metals, even simple denture acrylic and that there is NO such thing as a truly metal free dental material. All of them contain chemicals, metals and other things that have potential to cause immune reactions and disturbances/allergies. Anything in them that is an issue with your immune system will challenge and burden it and may hinder or even prevent healing from mercury.

Some people have gotten a porcelain replacement material but have not made sure it's solid porcelain and didn't realise it had a solid metal base in it that was covered with porcelain. So sometimes this is the problem, not the porcelain itself.

I wish I knew the answers, I am in the same boat. I want to get cerec porcelain, and yes it contains aluminium oxide in it, as do many dental materials, but I show to be compatible with it and have heard many good things about htis material from biologic dentists. Many of whom are stating it is the most biocompatible dental material to date and the closest thing to human enamel.

Nothing will ever be perfect. If it is any consolation, I had a ceramic in my teeth that had fluoride and no doubt aluminium oxide in it too if it was a ceramic (Tetric Ceram). I had them replaced years ago with another material and I got extremely ill and wished I had never touched them. The stuff I have in my mouth now after them is obviously worse. I cannt heal now or detox properly. I found out the ones I have now contain phenol (which isn't even a metal, but a different toxic substance for those reactive to it, like myself). Whether this is the culprit, or not I cannot be sure. But I am definitely worse off. HOwever, I had wisdom teeth removed too and possibly have jawbone cavitations, so it could be that. I really have no idea.

I do know the ceramic I had was obviously "ok". And Gradia is a ceramic also, so I fear those less than I do some of these other ones.

At any rate, you could email Walter CLifford and ask him about Gradia and what is in it etc and ask him what does he think of it as a material? and is it pretty biocompatible etc.

If you wanted to that is.
