Bio Copy still amazes
This patient has secondary decay under a pfm that is critical to the stability of his partial. Both the crown and partial were done just after the Korean War. He loves his partial. These cases are always my favorite. Think back to how we used to handle this workflow in the analog world. Pick up impression and take the patient's partial away from them for a week. They would then hibernate until we gave it back. The lab crown would never fit to the partial so we become human milling machines and try to adjust to fit. Bend the clasps. Break the clasps. In the end we end up with a barely acceptable outcome and offer to make a new partial. 
I agree. For those of us dealing with partials daily in small town practices, this is maybe the most amazing part of cerec.
Yes! Prior to CEREC/Biocopy situations such as this were nightmares with multiple appointments and the back and forth with labs.

Awesome BOB, I know we all get lost in the big stuff , and take these amazing features of CEREC for granted . Great reminder.
I have these cases all the time and I am amazed every time. The old way was such a pain and always never really worked. One of the many things that make me ask my self how do doctors without CEREC ever practice dentistry.

Valid question. I keep it at -175. It's a good idea to overlay the biocopy over the proposal to look for that nice speckling that validates an accurate stitch. It's hard, but you have to control yourself and not alter the proposal much with the tools or the partial won't fit.
I’ve done this exact thing probably 20 times or more. Yes, very smooth process with CEREC. Love this technology, especially during the times when we are on a bug-free software version.
