Hey all,

I just made the switch to Surpass and I'm very happy. I've switched from Amalgambond Plus which my father uses (hope to convert him too). I've got a few things I wanted to clarify before I go full speed ahead with it.

1. I noticed some people are etching the enamel margins with phosphoric acid. I agitate the uncut enamel an additional 5 seconds (for a total of 15 seconds) with Surpass 1, as the instructions state. Would etching with phosphoric acid be of additional benefit, say, when restoring class IV's, or would I be OK with just Surpass 1?

2. I've been air-thinning Surpass 3 with my directs for a few seconds before I light-cure. I assume this is ok?

3. After I place and adapt each increment of composite to the preparation, i dip the provided seamfree applicator in the well with seamfree, dab it on my glove a few times (to get rid of excess), and lubricate my uncured composite with the seamfree, and then light-cure. I repeat for each layer.

For my last and final layer, I dip my instrument in the seamfree, because I feel that it seems to "melt" my waxy/stiff Filtek Supreme Ultra, and it helps me blend it into my margins. Is there a problem with seamfree being co-cured with my composite on the outermost layer?

Thank you!

I use nothing other than Surpass 1 and you likely have seen my recalls. I'll put them against anything.

Yes, thin is good.

Not at all. Any Seamfree on the surface will not polymerize. It copolymerizes very well when covered by a composite.
