Part 5 - Cleaning up your final DURAthins.
Once all of the excess cement is cleaned satisfactorally, then the whole case is preliminarized.
Then we are going to use the precision floss and then gently pass floss through each one of these contacts. You know there is an element of this type of dentistry that is really hard to teach, the rules, you know dentist like to have, well you do this and then you do that, they like the cookbook format, we all do. But this is a great situation where passing the floss through here was probably not the right thing to do. Many times passing the floss through will pull that cement a little bit away from the margin and it’s real easy to pass once they’re cured, it’s real easy to pass something through here. Now we probably caused more harm than good but in many cases it works out well.
So once we have carefully cleaned all of the excess cement to our satisfaction, then of course we are going to preliminarize the whole case and we just have been very careful through this process. Again, not to elicit any hemorrhaging and problems with the tissue and we have tried to be certain that we have not disturbed the cement margin interface there that we have been able to clean the excess away where we know that we can do a nice speedy job on the clean up and still accomplish the goals we are looking for aesthetically.
Ok, so now we’re applying our glycerine to manage the oxygen inhibited layer and we’re going to do real deep and intense puliminarzation now and then we will begin our final clean up. So once we have puliminarized the case completely and we are down to doing some clean up and cement removal. First, I start with just a scaler and do any gross clean up there and then we are going to come back in just a moment and use a 12 fluted carbide bur which will work real well to go in and clean up the cement without putting undue scratches or compromises on our tooth or ceramic. One thing that I would love to point out is that right after we just do a gross clean up with a scaler and we come around and feel these margins contrary to what one might think since there is no margin or preparation for the ceramist to build to, you might think that there would just be this gigantic ledge or certainly a margin that we would not be happy with. But the fact of the matter is that the way that these are made, I can go in and feel the margins and they do not feel distinctly different from a conventional veneer case that I just cemented. And then once we are through with the marginal finishing procedure then they will actually be just the same if not even not a little bit better marginal interface and emergence profile than with conventional veneers.
