Hello,
Our lab is having a problem with manufacturing a 5 unit bridge that has one pontic in the middle. (actually, a lot of the multi-unit ones are being problematic...)
We use 3Shape for modeling, Zirkonzahn M5 to mill, and sintering with a Mihm-Vogt HTS-2/M/Zirkon-120.
We made a 5 unit bridge and it seems to fit the abutments in each die just fine, but wont fit perfectly when fitting it on a solid model with two abutments on each ends (4 abutments and a pontic in the middle).
It seems like it shrinks in ways that we weren't expecting and wanted to ask if anybody has had this kind of problem and how it was resolved.
Thanks.
