Acrylic to acrylic barrier

[Car 54]

Hello again, it's me

When I do a suck-down implant surgical guide, what do I need to use on a printed model so that the cold cure acrylic doesn't stick to the printed model?
I tried liquid foil, but maybe I blew too much of the excess off, as that really didn't work. Then I tried 3 coats of the Zhermack Gingifast separator that we use for soft tissue to a PVS impression. That was better, but the cold cure stuck fairly well to that, too.

What do you all suggest for me?
TIA

we end up duplicating, let us know if you find a solution!

Exactly thinking that is what I would have to do, too.

Siliform

Trigroup has formulated a full line of Siliform separator products specifically for use with 3D printing in the dental industry. Regardless of application, there is a Siliform material designed to meet YOUR individual 3D printed model separation needs! SiliformADL - a light-bodied separator...

www.trigrouptechnologies.com

This would be an option, We use it for cold cure applications but not for injection processing. You would want the Siliform BEA 3D model separator. There are more steps than a traditional separator but it seems to work well for us. Hope this was helpful!

Thank you, bdwalsh3. I'll give them a call and see what they say and of the cost.

Vasaline?

Vasaline?

I thought about that, but I didn't know if the acrylic that contacted the vaseline would cure correctly, and may be a bit pasty, or tacky there?

I have used Vaseline as a barrier for acrylic. I have not experienced any of the above mentioned issued. I guess you could do a trial on an old model and pour some acrylic on it...

Thank you, friend, I'll give it try

we tried the vaseline with not wonderful results. some areas it worked, others did not. was too inconsistent for us.
could be related to the resin?

And on the case I was working on, I was leery of vasaline as it needed to be delivered that morning, so I didn't want to experiment with that one. I'm more used to a dryer barrier like we use on a stone cast, in which ADS X-foil works wonderfully. What do you use on stone casts?

ivoclar separator works well for us. the old dentsply Al-Cote worked well back in the day too and i think we still have some of that kicking around lol

Diamond D Ultra Sep is what we use. A third of the price of Ivoclar and works just as well.

Taub Liquid Latex, should and does perform perfectly. Goes on White, dries clear. A perfect "Miniscule" barrier from all combinations. Have always kept on hand for that reason. I've had a sample size, diluted with distilled water and that was 10 years ago. Truly a remarkable product but get a small size unless using in a larger operation.

For acrylic to acrylic, this sounds like the way to go. I've used Taub before and have liked their products
Thank you, everyone, some really good replies have been posted

Yes, Latex go with it Seriously a perfect ban between all materials in my long lifetime. Thinned with water what more you ask for?? This could get off track soon as "Someone suggested"

I just talked to Taub to make sure of what I was going to order, and he said it is Rubber Sep. I remember that from about 25 years ago when I had a bottle for who knows what I was doing with it back then. He mentioned they have the white that dries clear, or the pink, which will stay pink. I think I'll buy the pink version just so I can see if there is any piece of it sticking to the surgical guide acrylic after curing.

@sidesh0wb0b @Sda36 idea worked great, thank you Sda I got the small bottle of pink, which includes the brush tip in the cap, and did a trial on a printed model. It wasn't the full-blown pontic fill-in and cured in a Lang Aqua Press. But what I did do was put some white rope wax on the buccal of the pontic area (created a dam),mixed some Jet acrylic and laid it on the pontic area and tipped the cast towards the buccal to help it not run to the lingual. I let it self-cure for about 45 minutes. It came right off It did leave a couple of little pieces of pink in 2 spots (which weren't totally set and were in crevasses) that's why I got the pink to be able to see any leftovers. I'm sure super dave was just using what he's had all of these years, but since this was a new purchase, went with the pink

If still someone is interested, sometimes its worth to RTFM... This is from Whip Mix's Verimodel resin brochure:

WORKING WITH PRINTED MODELS

• Models can be coated with a separating material such as Whip Mix's Foilcote, Lubritex No. 12, or Gator Die Lube to prevent wax from adhering.
• Models can be duplicated with silicone.
• When models are used to create orthodontic appliances, or denture bases, a non-food grade silicone mold release agent should be used to prevent acrylic from adhering to the surface of the model.
• Models can be used with vacuum form method to create aligners, retainers, and indirect bonding trays.
