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.
Dr. Alyssa,
Shouldnt the pulpla floor be flat so how can we give the up and down following the contours of the pulpal floor
It needs to be flat, as in not having lumps and bumps on the floor. It can have slight ups and downs following the DEJ, which is how the caries spread, that’s not a problem.
Dr. Alyssa,
This was for a composite restoration.
