contact with a bonding agent (that is any bonding
agent tested so far, even the dogs of the bonds). So, there is no opportunity
for a gap to form from the usual shrinkage, as you can see in the illustration.

Professor Sadr has posted OCT images (real time) of shrinkage as it happens; I will try to find the link and post it. What does this mean in the clinic?
No leakage and, I predict, no so-called "recurrent caries" (immediate clinical
failures) at the cervical margin. (A prediction because we have only a bit over
four years' experience.) Also, no "white lines," which is broken enamel. ■

think it's awesome-no staining around margins, even
on Invisalign attachments due to the giomer technology. I also use a bulk fill-3M Filtek One for larger increments, and have started
snowplowing the low flow not just in the proximal boxes but in the occlusal
portion as well. It seems to look great and really helps at the margins, but also
seems to mix in with the packable. Would this affect the bulk fill characteristics
of the packable? ■

pretty well, but it was just annoying how much extra
finishing/polishing was needed in the end to cut back all the excess. People will
cite studies that seem to show that in general it doesn't hold up well over time at
the margins, but I never found any real difference clinically. ■
