Can you use the "closed bite" technique to establish the occlusion???

Potentially.


But would it kill you guys to make some A3? Either material would be fine. Pretty please . . . Very Happy

Them's fightin' words! If you think I'm just gonna sit here drinking my coffee while you insult my manhood - you're probably right Very Happy . I actually did not know about A4 - I may have to try it.

Had a lovely 85 yo lady in yesterday with water sensitivity at #5 which had an old beat up MO composite with gingival decay. I had 15 minutes before lunch with my favorited girl and a brand new Injectafil gun, so what the heck! I gave her some 3% Carbo, got a dam on, prepped, Surpass, Titan, my first use of Injectafil, light cured, dam off, adjust occlusion, polish, glaze and out the back door on time! Would have taken much longer with my usual Heliomolar. Great product! Great lunch! Very Happy

When inserting Injectafil, I think it's best to allow the material to gel and then light activate for only a couple of seconds to reduce the 02 inhibited layer.

This is as low stress as it gets.

What are the physical properties of injectafi ?
When you say that they are better than anchor, could you provide us with some numbers ?

We're working on defining them, but I can tell you that the properties of Injectafil are better than those of Anchor. The modulus is considerably higher.

I thought we didn't have to worry about the O2 inhibited layer. I thought is was like the Easter Bunny - something you tell your kids exists, but doesn't really Very Happy

With a slow gelling material like this, the 02 inhibited layer is considerable. In typical situations it's not a problem.

BTW, we were then speaking of the 02 layer that remained AFTER something had been light-activated, right?

"Gel" stage , not set to completion, right? I read above in different posts that it "gels" at 1 min & also at 1.5 min mark. What is the ideal time to "light activate for only a couple of seconds to reduce the 02 inhibited layer"

FWIW, re the request for shade A3.
Some guy (Ron Jackson?) used to teach that if you use A-3 as the dentin shade then a clear or a translucent or a grey enamel shade, then the esthetics are great in 95% of the teeth; & sure enough we find this to be fairly accurate.

But when using Injecafil solely (as the enamel layer too) then I suppose that A2 may match more teeth than A3? I just don’t know until I get pleasantly surprised or let down for a few years. I do know that “A3 as the enamel layer” has different esthetics than “A3 dentin with a clear/translucent enamel layer”

In cases where my enamel layer is Injectafil, you still advise sealing the final restoration after polishing with Surpass?

What if the small restoration required no polishing?

This DC slower set alters the need for any final sealing?

Thanks

I do it anyway. Just part of protocol.
