[QUOTE="NicelyMKV, post: 50145, member: 476"] By the way, the wax printed crown is accurate to the margin I picked on the impression. There were a few areas that slightly softened during the scan so I miss picked my margin a little. I still think it was good for my 1st try. I will post the actual images of the correct impression scan Monday when I get back to the Lab. Better way for you all to judge the outcome. You also [B]HAVE TO MAKE SURE YOU PICK "REVERSE NORMAL"!!![/B] before finishing the project. If not, it will read it inverted in the CAD system. Yeah........I did that........ Also make sure you get a good scan of the buccal and lingual aspects of the impression itself for referencing the upper and lower impression scans together. Make sure when selecting the teeth to be scanned on the impression in the beginning that you make the circles as big as you can over each tooth selection position. You use the scroll wheel on the mouse to enlarge or shrink the scan area circle. I wish it gave you the free scan option at this point but it does not. I spoke with one of the tech support guys and he said he would pass it on to the developers. I also mentioned mirroring the slot on the impression holder so you can just flip it without having to take the impression out and flip it itself. When cutting the impression scan, cut off whichever arch you are not working with. You can then flip the scan over and cut the convex side and also it keeps you from accidentally cutting away the other arch. [/QUOTE]
