I didn't know what is was either, until CHL posted this thread...and I still don't know what it is.
This is similar to what 3M had with Lava Ultimate. It was a nano resin hybrid, also like Vita Enamic. It had low flexural strength but high elasticity. (3M had a picture of a crown on a shock absorber to give you a visual). The problem was, too much elasticity caused some failure at the interface of the crown and the natural tooth structure. Hope that helps!

Thanks KIM, it did help, and probably for some others too.

nano sized particles would need to be in a viscous stage to bond. However there is less filler which makes it weaker.
A higher viscosity allows for more filler such as denser composite or even zr,quartz,dung beetles........

pre Cured ( milled) nanocomposites just won't stick like sh it ona blanket and that is the problem.
