Hi all....
Haven't posted for quite some time.
Having a problem with Occasional chipping on margins. Sometimes they are perfect and other times chipping.
I milled 2 crowns back to back yesterday. One chipped and the other was fine.
Both are Straumann wn. Mill is a DX52 with newish burs, calibrated and cleaned weekly and DME are current.
Cam is millbox.
The only difference was with the disk sizes used. Upper molar was in a 14mm and the lower was in an 18mm.
Any ideas appreciated.
See pics.
Lower molar is first pic and milled perfect.
Thanks
