Medical Forum / General / Dentistry / January 2008Noble Crown?
What is a "porcelain noble crown" or "porcelain high noble crown" and how does it differ from a porcelain gold crown? Thanks >What is a "porcelain noble crown" or "porcelain high noble crown" and how >does it differ from a porcelain gold crown? > >Thanks Difference is the noble content of the alloy used. Largely cost, as you may know gold is quite high right now. >>What is a "porcelain noble crown" or "porcelain high noble crown" and how >>does it differ from a porcelain gold crown?

Noble metals have fewer tissue reactions, cast well, and have a history of long term clinical success. Base metals usually contain nickel or other metals that may not be totally non-reactive physiologically. :-) Steve >>Difference is the noble content of the alloy used. >> >>Largely cost, as you may know gold is quite high right now. > > Is there a clinical difference?

Are we playing "Jeopardy" ? Hey Henry, tell the guy. Gold is easy to cast, does not corrode easily, and has very few tissue reactions.
