Is the wax not fitting well or the metal after casting?
I've taken away all of the cement spacer for the wax. Individual copings after casting are nice fitting.... a little loose but workable. One bridge came out nice. Not as tight as a wax up would be but not as tight as I would like it still. I'm wondering if there is something within SUM3D to work with the fit. I was given a quick introduction to the nesting program but there's so much it can do.
Hi Nick,Any tips for correcting this problem? 3 unit bridges fit like a glove, but anything over 5 units then its rock city. I use the "create stabilizer" option which is supposed to keep it from warping while milling or cutting it out of the disk, but those bigger bridges still rock. Zirconia bridges (big or small) fit great. But the wax is giving me trouble.
Thanks
Nick

When does the bridge not fit? Immediately after casting, it could be your investment, Do hand waxed bridges not rock?The wax fits good (the Henry Schein wax) after milling, but it fits like crap after being cast. The new wax I used the past 2 days did not do well, and the wax bridges rock with the new wax.
Ill go back to using Henry Schein wax, but that doesnt relieve the rocking issue we've been having.

If your "bad waxers" invest the wax that could be your problem they could be lazy, don't care, insufficiently motivated, or are too undertrained to do it properly.Truth be told, we have bad waxers and they struggle to make 1 out of 3 bridges fit properly. But yeah, the bridges typically fit fine if waxed correctly. What could be the causing the investment
to be the problem?

Ok, it may be some issue with expansion. If you are starting with a good fit, your roland is doing the job right. Cast bridgework ( especially long span with more than 2 abutments ) its not easy. Also check your spruing technique. Do you have a photo?The wax fits good (the Henry Schein wax) after milling, but it fits like crap after being cast.

Have them sign off on the case they wax give them a dollar for every one that goes down perfect.Hey guys, thanks for the great answers. Seems like it might have been a combination of things. I changed my technique for cutting off the bridges from the wax disc, and hammered home to our waxers
the need to handle these cases with great care during the spruing and investing. Although Ive hammered home that point a thousand times, it never changed. So far, though, seems to be doing well, and perhaps
it was only my removal technique, although the wax bridges did fit in wax before I changed that.
Thanks again!

Well have the "boss" do some cross training, and have them finish the metal.LOL I tried that. Once offered to buy them lunch if they would stop waxing simple copings so thin (castings would get tiny holes as a result). 2 days a week they
wax some of their copings less than 2/10 of a mm in thickness, sometimes paper thin, and holes would result. So the lunch offer didnt work sadly.
But, to be fair, none of them speak English and likely make minimum wage (just my guess).
Also they do speak English, just not to you.LOL I tried that. Once offered to buy them lunch if they would stop waxing simple copings so thin (castings would get tiny holes as a result). 2 days a week they
