So I routinely do ceramic onlays with IDS etc with my CEREC and really enjoy this part of my practice. My question is when using heated composite how to treat the ceramic fitting surface? So after HF etching and silane do I apply a layer of bond? If so do I apply, air thin and cure or simply air thin then place heated composite? Thanks in advance and thanks for your podcasts!

[@protrusive]

Great Q - I have read up a lot about this over the years and the consensus is that you SHOULD place a thin layer of adhesuve (bond) on the ceramic after etching and silanating. You should air thin it, but should not polymerize it. Just add heated composite :)

What is the reason not do margin elevation with GIC? Benefit of Thermal expansion a less bond failure properties.

[@protrusive]

Hi Stephen! Thanks for the comment. My answer was silly (see the end) so I asked David Gerdolle himself! here's what he said: GIC is an interesting material regarding its biogical properties and its better tolerance to more humid conditions (no rubberdam). Nevertheless the bond strength and the mechanical properties are far lower than composites. When conditions are difficult and when the isolation especially cannot be achieved properly it could be an alternative material though. We have a few cases of those and are waiting to see what happens to them over the years. At the moment, it doesn’t look as the best material for the purpose. My answer was: If DG and Pascal Magne et al use composite, I will use composite. I prefer DGs answer!
