[QUOTE="Al., post: 19917, member: 382"] Hi Charles, Thats intresting about judging the shrinkage with different frame works. The one place it is really critical is with anterior dentin cutbacks, to be safe when I have a doubt I do a seperate dentin build like on the limited space build thread. Its taken me 5 years to really get to know the shrinkage for inline. Its become instinct. thats why I hated it when they discontinued Will Ceram I had to learn a new porc all over again. One thing I noticed is that the layering porc for emax has quite a bit of shrinkage and sometimes it seems like it will shrink on 2nd bakes in areas I didnt add on. Charles are you talking about adding on embrasures or connections on bridges. Just till recently I did the same thing, added on cut into it and added on again only to find a void I had to fill in at glaze. Now on my 2nd bridge bake ant. and post. I fill in the connection area and recut it as deep as I can, same if you do a third add on, cut it with your ultra thin blade. That has saved me sooo much time on bridges. [/QUOTE]
