Dental Porcelain: Metal or Not Metal? Compatibility?

Hi people.

Iím about to have a gold crown put on a non-rootcanaled tooth. It will be an alloy which has only gold and platinum, and very little indium. I decided to go with gold after long research. I did a compatibility test done by Biocomp Laboratories (similar to Clifford test). It showed that Iím highly reactive (among other metals) to aluminum and zirconium. This crown is a first molar and for esthetical reason Iíd like a porcelain veneer on outer surface since when I smile itís still visible although not as bad as on frond teeth, of course, but stillÖ

Now, I know that all porcelains have metal OXIDES, which are not exactly a metal form but more like a powder, or sand. These oxides are called with ďaĒ at the end. Such as ďaluminaĒ (not aluminum), ďzirconiaĒ (not zirconium). But my test lists metal forms only (with no ďaĒ at the end): aluminum and zirconium. Is it safe to put porcelain with metal OXIDES if Iím reactive to mentioned METALS (non-oxides)?

Because Iím highly reactive to aluminum, all porcelains in the long list of materials in my test report are listed as highly reactive. Then, thereís a list of same porcelains being tested excluding aluminum (as if there was no aluminum) and sorted out to highly, moderate, and least reactive. This is done for people who have no choice but to use porcelains even if they are highly reactive to aluminum. In that list there are plenty porcelains that are least reactive for me.

Do you think OXIDES of metals that Iím highly reactive to (but not metals themselves) would be more or less safe to use? I will need other dental work and I think I wonít be able to avoid porcelain anywayÖ I want to believe that itís safeÖ but please give me you input.

Thank you!
