Pat, have you found it easier to get better fits printing or milling wax to press, or using emax cad when your making a crown over ti ?
Its been so long since I pressed, and now using emax Cad, I'm having a hell of a time with fits on Ti.
I get the worst Ti abutments on pour models from docs to scan and design ! Very parallel, almost undercut, shallow retention groove and no flat wall and other times I get lucky with a more ideal Ti prep . Sometime I'm forced to change my X/Y from .02 to .01 and increase the start of cement gap and back off cement gap thickness on these worse cases. No fun learning how to improve the fits using a scanner !
The last few times I hand waxed and pressed inhouse, I used 1 layer die spacer and 1 layer to hand wax to cast with pfm alloys. Much better results and I don't remember changing the special liquid ratio. Waxing any prep on die stone to press, I stopped using die spacers which I forgot about. lol
