Concerning 3Shape, I can give ya what I know.....for those interested. Now this info is for a dental office, don't know what the "rules" are for a lab. Info was collected in Dec/2016.....could be different now we're in a new year.
When you buy a scanner they give you the acquisition software and subscription for the first year. It's called Dental System. Yearly subscription is $2150. If you want to design, CAD, the module you need to buy is Practice Lab. It costs you $4300 (they was going to throw that into my purchase, but I had to entice). Annual subscription for that module is $660.00. Then if you want the implant module, which is called Implant Studio, it's gonna cost ya $6000. I don't know what the annual subscription was for this module because I was gonna use Blue Sky Bio.
So, there ya go. That's all I know, AND, I had to pry it out of them for some reason. Which, in the end, made me very leery. I get nervous when you try to hide something from me. And this last part comes direct from a regional manager....if you quit paying the annual subscription to any module, you can't access the software to that module. Basically, they got ya by the tender pieces.
So in the end, it was too costly and secretive for me, but they do have the best scanner in my opinion.
