We have been seeing some loss of accuracy due to the incompatibility of scanners and large articulators. Yes, we can fabricate bite registrations and scan them. But, we are seeing some inaccuracy on some cases using the said protocol. In addition, we have had some problems on full arch reconstructions with alignment of a diagnostic cast scan data. I'm sure there are additional scanner and scanner software weaknesses.
So, for the purpose of this thread I would like to talk lab scanners only (NO CAD) and discuss what are the priorities if one was to purchase a lab scanner. I think the following is some of the important criteria needed to make an informed decision.
Multi die scanning
Scanning models with large articulators
Scanner support and loaner program
Ability to overlay study cast scan for full arch recon
Powdering or spray for metal components
If you have additional criteria to add to the list please do so. I would love your opinions on how you would prioritize the list. What would be on your wish list for a new scanner?
As always, looking forward to your thoughts.
