I have 3shape and exocad(barely use it) already and blender for dental, i can access itero and cerec cases as well. The company whom I'm helping out is massive compared to my operation. They have 10 PM7's and many PM3's and they have 5 formlabs printers, 5 3dnext printers, and a few asigas. They have the cashflow to do whatever they want. They only do crown and bridge, the owner doesn't like the mess of traditional dentures and will only mill them or print them. And he's been outsourcing transition dentures only for transition to PFZ full zirconia arches. They charge 250 dollars for the denture now and I charge them 200 (my normal economy fee). I would be damned if I was to 3d print a denture and sell it less than I do when I wax it, invest it, boil it out, finish, polish. The prices I have above are directly from Ivoclar sales rep. The problem is that labor becomes 50-60 percent of your overhead when doing things traditionally as oppossed to 20-30 percent digital. If you were doing it by yourself, it would suck 80 hours a week (I did for 8 years). or paying 20-30 dollars and hour for 10 employees. As I dont print dentures myself now, but I can make 10 nightguards vs 2 in the same labor hours. With splint studio it takes about 10 minutes to make it, and 2 hours to print (i work on other things during that time). I can get 6 on my printer. I usually do two prints a day. I could print 10 or more if I stand them upright but they're so tight. I found 20-60 degrees is the best for fit, no grinding, just cleaning, removing supports, curing, and polishing. I digress.I've been using 3d DLP printers for 3 years now and I've procesed denture on 3d printed model. I've had dentures completely bond to the models at first. I process hard night guards every day on a printer, I've added acrlyic to them and they've bonded each time, there's no line, no seperation, they grind and polish the same. All the resins I use are generally are methacrylate based. I've visited headquarters for a resign manufacturer for training, there was two ways you can bond to 3d printed dentures. I've repaired 3 of them in the past year, maybe? i've used regular acrylic, it partially bonds but leaves a line on the denture and looks funny. The denture needs to be cured at least 60C for 30-90 minutes to be fully cured. They say 30 minutes, but I've experienced issues on 3d printed parts that are not fully cured. I either use UV curing glue to bond surfaces together or its possible to use the denture base resin, partially cured to thicken it up to bond the tooth directly to the material. Now if we're talking bonding a tooth to valplast, just laugh.</blockquote>
