I’m 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 I’m highly reactive (among other metals) to aluminum and zirconium. This crown is a first molar and for esthetical reason I’d like a porcelain veneer on outer surface since when I smile it’s still visible although not as bad as on frond teeth, of course, but still…
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 “a” at the end. Such as “alumina” (not aluminum), “zirconia” (not zirconium). But my test lists metal forms only (with no “a” at the end): aluminum and zirconium. Is it safe to put porcelain with metal OXIDES if I’m reactive to mentioned METALS (non-oxides)?
Because I’m highly reactive to aluminum, all porcelains in the long list of materials in my test report are listed as highly reactive. Then, there’s 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 I’m 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 won’t be able to avoid porcelain anyway… I want to believe that it’s safe… but please give me you input.
