So, I’m going to stage the teeth now for the dental acrylic.
I’m looking for its viscosity to be,
it’s better to err slightly runny and stir it for a beat
and it will like densen up the molecules all together.
Basically what this one does is it melts.
The monomer melts the little bits
and then they will stick all together
and that’s where the plastic comes from.
So now I’m going to just pour this down in here,
and I always angle my mold a little bit.
And then in.
And right into the pressure pot.
And so if some burps up like this, it came up out of the vent,
you just cut that off a little bit and flatten it out.
Keep the top clean.
Then in.
So I’ll bolt it up, up top.
Now you have no time, you have to go.
So everything must wait.
Even tightness on these.
I had this already preset to 40.
It will be in here for about 20 minutes
and it’s right now at 25 psi and climbing.
Most dental applications you’re going to be running 30-40 psi tops.
So, there’ll be some hissing air.
And this is a good way to know you’re done.
Like I had saved my cup.
When that makes that kind of noise you’re pretty safe.
Here we go.
Now I check the edge.
It’s cured.
It’s thin right there so it’s probably just fine.
I’m going to ease around and check the flash is the next cue.
So I touch the flash that I had cast in there, right in here.
That little piece of flash, and that’s hard.
That tells me they’re done.
Alright, they turned out good.
That’s the first part.
So I’m going to open up the next one.
Same thing.
Pull it around, check the flash.
Since I know it’s the same batch, it's fine.
But it’s a good habit to get into.
And when you pull them out,
you want to make sure when you pull them out that you don’t
bend and rub the teeth all up through the mold.
So when they come out they should come straight out
and not like a big weird thing like that or something.
So these look good as well.
The next step is to get this flash off that we just put on there.
A lot of the times with the PVA, it’s this easy.
Now, it can not be that easy if you don’t PVA it.
This stuff will be fused.
So I’m just going to peel off any of the thin bits that are around the back.
As much as I can get.
And that’s pretty much where I’m going to stop for now on the clean up.
