what do you mean that zoe is not to be taken lightly for veneers? do you think that these veneer temps(2 together) will come off at the seat appointment since flow or resin temp cement was used to hold them in after a coming off a few times with temp bond?

No, I mean that there is always some effect of ZOE on resins and for veneers ZOE is an inappropriate use over resin. Best to start over.

2 short crowns.
PFM's
sandblasted intaglio of crown.
bonded crown into place with simplicity and anchor.
Both very sensitive afterwards.....
provisionals were pain free.
removed both crowns this week and re-provisionalized.
I've only had this problem with PFM's that I've attempted to bond.....near zero sensitivity on composites and ceramics.

good quality sensitivity.
thermal mostly.
chewing occasionally.
in the essence of trying to take all the responsibility for the problem I removed all occlusal contact (1 patient needed anesthetic). 2 weeks later there was still no resolution.
Maybe waiting longer is the answer but that is a hard one for me to suggest and for the patient to accept.

I was wondering how anchor w/ a PFM might comapre to a RMGI cement as far as bond strength (w/ reactivity to metal)-- i.e. if you gain that much by using anchor in these situations. I am intersetd to hear why there might be sensitivity in your case.

Were the preps sealed when cut?
I think I'd recommend apply two layers of Simplicity or use Surpass if you have it.
Not sure why you're having a problem.

You might have better luck sealing at prep visit and then again if you choose to bond them in subsequently.
