Question : Fully Automatic dental milling machines

Hey guys,
I am doing a research for this dental lab. They are looking into investing in a milling machine. This is the one where it takes the teeth impression and then cut out the crown, bridge, implant, or even a denture from the material provided.
Anyone has any knowleadge about this? What's the best/famous maker, model? Where to buy?
Any info appreciated.
Thank you!!
