exocad issue? or milling issue? Occlusion high and IP open...

[WENDY]

I have been having the same problem for the last few months.
On exocad, the occlusion is designed open and the IP is high.
But after milling and sintering, the crown has a high occlusion and open IP...

Is this a scan issue? or milling issue?

I use MEDIT scanner, exocad, millbox, and a roland mill.
Thank you.

Looks like you're giving yourself some extremely tight tolerances, give yourself a little cushion, with tolerancing like that anything can throw it off. Bite looks ever so slightly off, perfectly fine for most scenarios but with a 0 gap if any hair the lands near any part of the process then you'll have to adjust

Would it affect the fit if the problem is milling? The fit on the die is perfect...

Thank you for your advice - would you recommend opening the occ a bit more? What changes would you make - scanning process, etc./)

I see - what would you differently? Calibration? Change burs?
