Implant is rotated

[Kodi]

Hi guys,
I have an implant crown that came back from dentist because it’s a bit rotated and the position in the patient mouth is different than how it is on the model .Any ideas about reasons ? Thank you

when the model was poured it was probably not properly set from being in a closed tray.

could also be a problem with the open tray not having fully seated pickup, could be a problem with the implant library, could be a problem with the scan operator misaligning the scan flags either on purpose or by accident...

If vertical position is correct but rotation off, then the impression was most likely good, the placement off the impression coping and analog was most likely the culprit. If vertical position is off, then either the impression or placement of analog was a problem.

This is why I love digital. Also, why I happily give my docs the scan bodies to encourage scanning instead of analog impressions.
