    Dr. Alyssa,

    Can you please share the clearance for the ext angles for class 2 composite restorations? I usually struggle with the clearance being conservative for composite vs amalgam and the placement of exit angles

      Same as amalgam. The way we’re doing these we’re assuming the caries is very small and we’re doing a very conservative preparation. The dimensions of opening up the box for an amalgam prep is already at it’s minimum. We need contacts clear for the sake of convenience form.
      And for both, angles should be 90. I shouldn’t be able to tell whether it’s a composite or an amalgam prep by looking at it.

      Regarding the floor, it should be flat as in no bumps along the way. But it does not need to be totally on 1 plane. What benefit does it bring? The floor should be placed just inside the DEJ which is where the caries spread, and the DEJ goes up and down.
