As you've taught, I cure Titan simultaneously with Surpass 3 and I cure it with the Valo for 15-20 secs. I'm often using WO Titan. As directed (you always say follow the directions so I'm telling you I do) I pulse-cure my composites (Helio or Filtek), initially for 2-5 secs only for each increment (depends on how awake I am at the time; Im old you know) then add more time a few secs at a time as I add increments, finishing with 10 secs from each side. So I'm wondering what is it about Titan, and all flowables I assume, that allows us to blast it with light without damaging results???? Thanks - Tom

Being a really thin layer. Cool

Like your results so far?

Yes John. The resuts are great! So if the layers are thin they can't damage the enamel if they shrink too fast????

Is it better to cure the Sur 3 and then place Titan or cure the Sur 3 and the Titan together?

Right. It lowers the tensile stress

I do them together.

Thanks John
I was curing them together and then I thought I read in a post somewhere to cure the Sur 3 and then add the flowable, which is the way the video instructions describe the process.
Does it make for stronger adhesion bonding them together?

It makes for a resin-adhesive structure at the pulpal floor and makes for a radiographic sunny day.

I got it that it makes for a radiographic sunny day curing them both together, since there is the possibility of a radiolucent area under the composite if you cure the Sur 3 separately and don't really thin it out before curing.
But today, I was placing a Cl 3 comp on a max central to close a space left after ortho. I was more concerned in this case about getting maximum retention than a radiolucency on the X-Ray.
So, for maximum bond strength does it make any difference if the Sur 3 and flowable are cured together or separately?
At the Ultradent Summit, their products were always cured separately.

The technique is indicated for Class I's and II's.

This isn't Ultradent. It's Apex! Razz
