I use Anchor nearly 90% of the time. Occasionally when I have a very retentive prep, I'll Interface my Emax and Sur3 it, cure it, load it with Maxcem Elite or Rely-X Unicem and seat it.

1) Can I also 1,2,3 the prep with Surpass and will this improve bond strengths, or will it mess with the Self-etch of the cements?

2) Any problems with not treating the prep if I Interface and Sur3 my crowns and then seat with Maxcem or Unicem?

3) What other go to cements are you using besides Anchor? I mean for cementing and not bonding when isolation is a problem.

Thanks.

What is the reasoning behind not using Anchor on very retentive preps?

BTW, using Surpass prior to any self-etching cement jacks the bond strengths way up.

I think you'd be crazy not to use Surpass with those cements.

The margins will thank you later.

Okay John, I'm going to step into this and guess how you re-cemented that crown.
First of all I'd have sand blasted the inside of the crown, sealed the prep with Simplicity and re-cemented with Rely X cement.

I'm thinking, you sand blasted the inside of the crown, placed Surpass on the prep, ( I think you didn't cure the Surpass 3 but just air thinned it, since curing it might have caused too thick a layer for the crown to seat properly) then put Anchor inside the crown and cemented it.
You waited till the Anchor gelled a bit then cleaned the cement off, or after you cemented it you zapped the margin briefly with the light and began cleaning the cement off.

Actually to be honest, I hate to admit I'm not really sure how you re-cemented the crown, but I'd love to know.
And while I'm at it, if the crown does require bonding, what is your protocol for cementing it?
Thanks as always.

Nareg is right. It went back on with Durelon.[/quote]

JK please comment on the above technique. (self curing sur 3)

[john kanca]

Surpass 3 is always light-cured. It's part of the video. There's always the instructions, if nothing else:

Would it be exceptable to use Rely-x Unicem 2 as a cement for and then in combination with surpass on the topoth and interface and sur 2 on a cerec crown?

Thanks,
We are looking for a new luting cement and the doctor that works with me want to use the same cement for both pfms and for cerec. I will continue, as always, to use anchor and surpass. Why change what is not broken.
