ooh sorry Cata didnt see your post.
I've done this; don't know why I didn't recall earlier.Just soften the tray with a torch, dismantle tray and cut off pvs with a scalpel
That's how I do it, time consuming but it works.cut the tray off the impression first and then strip the impression from the model
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!!!Just left a model all weekend and broke not one but two of the prepped for partial teeth. Had to tell Dr need new impression.

Nice I picked up a 6 hour old alginate once unpoured and thought that was bad.Well at least you poured the model.

Their patient isn't going to be happy about having a new impression taken, the script said she was a gagger.Nice I picked up a 6 hour old alginate once unpoured and thought that was bad.
Segway.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!
Not really your fault, but they will blame you anyway.Their patient isn't going to be happy about having a new impression taken, the script said she was a gagger.
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.Segway.

Of Doris or the alginate?Take a pic and post it up on the facepalm thread
It's already been sent back to the office....Take a pic and post it up on the facepalm thread
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 worksI am not sure of the heavy body. Most of my accounts only use alginate or accu-gel. I am not very experienced in polyvinyl impressions. I am using a Type III lab stone. Should I ask for them to use the pink polyvinyl strictly? I have noticed it being more flexible. Great idea on the hot water. Thanks
View attachment 26603 Hi!
I have one dentist account that always sends me polyvinyl impressions. Not only are they missing landmarks sometimes, but no matter how I pour them, the teeth always break off in the impression if they are bulbous. I am so frustrated and want to request a different method. Most of my other accounts send models that are poured in office or alginate impressions. This account ships cases to me. I always spray the polyvinyl with model release. It doesn't matter if I use die stone or let the stone harden all damn day. Is it me and something I'm doing? I just want to make the best appliance I can for them and if I can't get this impression situation under control I may have to quit doing their work. It's not worth the headache. HELP!
