Recommend me some crowns, please?

[foxleybob]

I had a traditional bridge fitted to my front upper jaw approx 20 years ago, which has not broken off, unfortunately.
This has left me with a 3 tooth gap with two broken stumps that supported the said bridge which is rather ugly. (matches my face )
I have been in touch with quite a few different dental surgeries who advised a scan, which I'm looking to have done soon.
My question is.............if I decide to have a make-over (Front crowns etc etc)
Should I always choose Zurconium over anything else, and likewise Strauman for implants?
Any advice will be much appreciated
