Hi there, I am new here, but I found this topic interesting.
So please allow me to share my problem. We have a Kavo Everest machine,
On a four unit bridge case made a full contour zirconia DD cubeX2 ML with Scaling Factor or Code 1,229.
Initially I used 20% shrinkage setting on our machine and after the sintering the bridge was too wide, and was not fitting on the model.
Then I used the same bridge and I assumed that according to this Scaling Factor or Code 1,229, I should change the percentage to 22,9% and I milled it again.
So the bridge after the sintering was even bigger and there was no way to fit.
So I searched on the web and I found that there are different formulas for converting the scaling factor to percentage, and there is a specific type or letter listed in front of the number that stands for the Code written.
So can you help me?
What is the EXACT percentage of shrinking on DD cubeX2 ML material and because it is a different number on every blank, HOW CAN I CONVERT IT INTO PERCENTAGE!
Because 1.229 OBVIOUSLY is not equal to 22,9 according to the obtained results.
