It is really important, using the Sim 2 brush, to wipe a thin layer of Sim 2 into the prep in between layers of composite, and especially prior to the enamel increment. It makes each increment seamless.

John,

Is there a potential problem not air drying these wipes? Cool

If you think there's still some solvent there, then dry it a little, but for the most part, by the time you do this I figure the solvent has evaporated from the brush.

ok, i'll start doing that but i have a question that is sort of related. my asst. generally wll coat sim 2 on a thompson placement instrument so the composite doesn't stick. will this effect the longevity of the enamel/composite margin?

JK,

I have been doing this religiously for the last few months. I can't believe how it has taken my composite esthetics to the next level. they just look amazing.

Yes.

I think it will make them last longer. Cool

John-
I have only been using the Sim 2 brush on the final layer. Not the internal layers.
Are you concerned about adding and curing multiple layers of Sim 2 at the margin every time you add a layer internally. By the time I get to the final layer, it might be 3 or 4 layers of composite. I do not think I can avoid putting Sim 2 on the margin each time and I am concerned if there would be too much thickness of Sim 2 being built up there.

OK, but what it does it help adapt each new layer to the old layer and makes the layers imperceptible on subsequent direc visual examination. It's so thin that I haven't seen any untoward effect but use your judgment.

Coat your placement instrument lightly with Sim 2. Too much Sim 2 on the instrument as you place and taper the final layer of composite to the margin could act as a diluent in that area which might decrease the wear resistance of the restoration in that critical interface. I like to coat a microbrush with Sim 2, quickly wiping the microbrush on the patient napkin, and then going over the margins where needed. It works well for me!
