- Apply another coat of Sim 2, but DO NOT LIGHT ACTIVATE


Crown:

- Lightl sandblast internal surface of crown; 27 micron Al203 particles recommended.
- Apply Interface and DRY
- Apply a coat of Sim 2 and light-activate 10 seconds

John-
Would it be okay to bond an Eris crown with Rely X Veneer cement (with Simplicity and Interface)? I held it up to the light and it looks thin enough for light to get through it.
Thanks...Howard

If you feel you can get light through it, that ought to be fine. Cool

I was wondering-- as I am using Unicem with Simplicity underneath it when seating an all-ceramic crown or onlay, if there is a "lesser" hybridized layer (aka I missed with the simplicity), will the self-etch properties of unicem still help on out with the total bonding in that area?

You have far higher bond strengths and hybrid layers using Simplicity and Unicem than with Unicem alone. Unicem is monomer-rich and it bonds famously to the Simplicity resin layer. Very Happy

how important is it to leave an uncured sim2 layer on the tooth?

If you are depending on the dual-cure or self-cure aspect, it is important. If you are dependent on light only, then it is not crucial.

John if I have already sealed the tooth with Simplicity at the prep appt, then when I come to seat a ceramic crown with RelyX Unicem would I just put a layer of Sim2 over the tooth but don't light cure it?

You could, but not necessary. All you really need to do is clean off the temp cement, rinse, dry and apply the Unicem. Cool

I am applying Simplicity at the end of the prep appointment with great success.
Is there any harm in doing it again at the cement appointment?
I'm thinking what if there was a little contamination as I applied it at the prep appointment that causes the tooth not to be "Simed" 100%. Especially if it is a ceramic crown that I'm going to bond in with Interface and Anchor. Can I apply Sim 1 (or Interface) to the prep and Sim 2 again if I did it at the prior appointment?

And those few instances where I am just going to cement a crown with Fuji Plus and they needed to be numb for the cement appointment due to sensitivity. Any problems if I re-Sim the tooth first at the cement appointment?

Thanks...Howard
