      cut the tray off the impression first and then strip the impression from the model...I have done a few cu-sils that way and it is always a bit** getting the model off without breaking the teeth....So I just cut the tray off first and then cut the impression off the model..

      I've done this; don't know why I didn't recall earlier.
      If you need a dupe, it'd probably be better to have that in a more flexible silicone instead of trying to repour...

      That's how I do it, time consuming but it works.

      Well at least you poured the model. We got a call Thursday @ 2:45 from an office that closes @ 3 for a pick up, they're closed on Friday so I said I would pick it up this morning @ 7 when they open. So I get back to the lab, open the bag and what do I find, an alginate that hadn't been poured. It sat for 3 days!!!

      At least you don't have to drive to him.

      Oh, wait, dude, you've got to get one of those little battery powered kid cars and drive it to the operatory and back!

      Nice I picked up a 6 hour old alginate once unpoured and thought that was bad.

      Their patient isn't going to be happy about having a new impression taken, the script said she was a gagger.

      Segway.
      Not really your fault, but they will blame you anyway.

      Not my fault at all, they didn't tell me it was a wet alginate when they called, otherwise I would have told them to pour it or stay late and wait for us to pick it up. But you're right we'll get the blame to the patient.

      Ah immediate, I apologize to the Dr. for breaking #8 off the model and He replies "Don't worry, #8 fell out at the front counter while the patient was making his next appointment."
      Had another that had a "Nanny McFee" central, no bone just soft tissue holding it between the upper and lower lip.

      Put the poured and completely set impression and model in your boil out tank for ten minutes , then pull out with gloves and open with a knife, left side then right etc slowly. This is what I was taught years ago...it works

      I hate those too. I would first ask the doc if he could switch to alginate (are these for opposing models or...), or switch to something that is more user friendly. If he doesn't, I would advise him that he should send two impressions (second just in case) because you will be destroying the first one impression by cutting the model out of the polyvinyl so you won't break it.
      Edit... I see these are for immediates, again I hate thos kind of impresssions for dentures, maybe you can get him to change products.
