Hi everyone, I am curious about the basics with digital impressions and physical impressions. The dental lab has a digital scanner, 3D printer, and milling unit. What happens next when dentists send their physical impression of the patient's mouth? Correct me if I am wrong. Do dental labs scan the physical impression received from the dentist with a digital scanner, and the models and crowns are created by the 3D printer/milling unit? As for digital impression, it skips the process of scanning the impression and the only important step is fixing the margins/removing any bubbles? I just want to know the reasoning behind all of this since I am always at a dental office rather than a dental lab. Thanks!
