Crown Identification for model less cases

This may fall under the heading of stupid questions but I have to ask. We recently increased the amount of crowns received for model less crowns. A few a day presented no problem but with the increased amount came the increased possibility for mix ups. Does anyone have a good system to avoid the confusion? For example, if you had several #3's all of the same shade. One tech is scanning and designing the crowns and a different tech is finishing and staining the crowns after milling due to the different skills required for the steps.

Short of matching the sintered crowns to the design file, which is a large waste of production time, what system do the bigger producers use to avoid possible mix ups? Is there some method of identifying each crown while milling? Making a map index of the disc is one method but takes time and is not foolproof. One possible method if using 3Shape, is there any way to desigh the crown so that an identifier is lightly milled in the intaglio surface, particularly on posterior crowns.

Any advise for any method anyone has in place would be greatly appreciated.

Thanks,

JDC

With milled emax we made the ND shade stump die, marked the name and put it in the case pan. We also played around with screen shots of the occlusal surface, printing and putting in the case pan for zirconia. Still not fool proof, but way better than looking up the design files to match them up later.

Thanks for the help. I need to become more familiar with the capabilities of sum3d. Tried it. Should work fine. Thanks again
