Millbox abutments rotation

[Bellaceramics12]

Hi! Anyone had alignment issues with abutments nested in millbox? 80% of the time our abutments are rotated, no matter how we try to align the blank. The ones that come out fine are purely luck. Is there a specific way to import the .stl file? We are new to millbox and couldn’t find any manuals.

what makes you think your mill is quallified to do repeatable non rotation ?? and what for are these adaption values see pic ??

We are milling Ti abutments and it comes out rotated, the buccal is either towards the mesial or distal. It mills fine and fits well but not in the correct position.

Maybe time for a bit zero point education.your mill supplier can help

I use millbox all the time for this. You should not have to realign the abutments if you are using the correct files, scan bodies and parts. A common mistake is how you import the file into millbox. If you are importing just the stl file you lose the xml file and that is what provides orientation. Make sure when you import your file it is in the folder that has the xml file and that info will come in automatically. The other issue might be parts related. The scanbody used dictates what blank you can mill with.

Yeah as others have mentioned, you're probably using a mis-matched scan library with your Pre-Milled Abutments or using mis-matched blanks with the fixture / system that your mill came with. Check with your supplier to make sure you have the latest CAD library so everything lines up. If you're trying to process non-oem parts on an OEM configuration, you have to know the discrepancy in the geometries otherwise you'll always be guessing.

Moral of the story - Use official / supported blanks with your pre-milled systems - especially when you don't understand how these implant libraries are setup / configured.
