Scanning impressions is a disaster in my opinion. There are too many places where the impression material is just wispy little fins of material that the scanner cannot see. Spraying it with reflectant only makes things worse, and the image is obliterated. If you want a digital impression, take one with an intraoral scanner. On the other hand, a Micro CT scanner takes beautiful scans of impressions which is why the Ortho CAD companies do it that way, but they are expensive, cumbersome, the files are huge and need conversion and segmenting to be manageable. Stick to analog model, poured from stone. My opinion anyway...
