Astron self adjusting splint material

[Brian]

Brian,
The negative has tin foil substitute on it when I press pack. When I pour in hydrocolloid, I just use the wet model, no tin foil substitute. Should I scrap the TFS?

No, no trial pack, I don't trial pack anything press packed, never have. I am processing 1 hour at 120 per directions and then chilling under running water before divesting for 25 minutes. It does appear to get clearer as it gets colder.

No, I wouldn't scrap the TFS... I'm just walking things out loud.... When I press pack, I trial pack... I don't understand why your having the results that you are??? I'm befuddled...

Set up issues ...

Astron makes great materials! I used their Clearsplint material years ago until I found Variflex from Great Lakes Prosthodontics. Variflex is a self-curing thermoplastic and has mutliple uses such as occlusal splints, surgical guides, stayplate retention, stabilized baseplates etc...

We have had problems with the Astron material and switched to Variflex - we have always poured with excellent results and do about 20 a day. We have noticed though with the 2:1 ratio the material will set up in the middle of the pour. Do you have any tricks to share, or a different ratio that still allows the material to cure?

I have used the astron splint material.. Its pretty good but I like Impact material.. Just about the same I'd say..

Yes, This is a great material,
place at 60 degree water, can make some adjustment.

and the best thing is no monomer smell ever! and never turn to yellow with age

1 CLEARSpiint came out before Variflex, (the Varifelx has a lot of smell to it, like the first formulation of CLEARSplint did.) More in line with IMPAK, with the same taste,smell issues. IPAK was the first material I used for nightguards in 72, with Henry M. Tanner DDS lower brux appliances.
Fricke comes out like glass but after a year it starts to yellow & I found quite a bit of fractures around the molar area. (I articulate and mill in my night guards, mill in is not the issue).
Dualaminate are fine for a short term appliance.
Here is a tread to check out.

My 2cents worth FWIW I've only been doing bux appliances since the 70's. What ever material just try & do your best, not just look for the fastest or cheapest.
