Then comes the familiar part of a deep posterior composite: place an increment, adapt it, cure it, place another, cure again, build the next layer, cure again. There’s nothing inherently wrong with incremental layering. It’s a technique most dentists know well, and in the right case it gives you a great deal of control.

Polycarboxylate cement covers much of the same clinical territory, which is precisely why dentists som...
