Well i'm not sure about that. apparently a dentist made the attempt. How great of a demand/volumn is there for a BH molar????? Now that's a one-of-kind isn't it??? So if that can be done for a one-off production then why not car parts too????
Actually, I've had a second molar repaired like that. Though each piece is unique to the situation, the "flexible tooling" provided by a desktop computer, IR camera, CAD software with specialized UI, and the comparatively small "milling machine" is what makes it possible to produce a custom "part" in about 20 minutes (with total time in-chair of about an hour).
My dentist offers this CEREC process as an alternative for any dental restoration (except front teeth), where the tooth wouldn't hold a conventional filling. In my case, these were teeth that were filled back when I was in college, and drilled and refilled at least once more in more recent years - not much left to work with, now.
However, cost IS a limiting factor. The repair to these molars cost me $700-800 each - again, slightly more than a conventional porcelain crown. Though not as smooth as a crown, they look and feel better than a big old amalgam filling, but the high cost of CEREC restoration can't compete when a smaller, traditional fillings will do.
Getting back to Packard, I'm sure that something along these lines CAN be done for Packard parts, but what vendor would step up to the plate, especially in this economy? What owner would pay $700-800 for an ignition bezel (even if "new and improved"), when Howard's repair is available?
