How do You test accurate fit of crowns ?

[Jack_the_dentureman]

Hi.
I always used sprays such as arti-spray from Bausch or Occlutec renfert or any similar.
But I got tired of the mess that these sprays do. Everything around my desk is blue or green or red depending on what color of spray i had.
In every corner of the desk

Now i want use contact color applied with a brush
something like Arti-spot, hope that will be cleaner.

So I started wondering how you provide accurate fit of Yur crowns ?

I mark the die with red pencil, works great!

what on earth?!?!

proper waxing or milling procedures. period.
dont use sprays or marking things of any kind. never liked them. take your time making sure your wax, investing, etc is accurate and you shouldnt have a need to adjust on the inside much if at all. (even under 10x power microscope)

@CoolHandLuke how did you get this crown to fit so well??

maybe the better question is why you have pics of CHL with his crown on and nearly nothing else...

He posts them to phone polls, they aren't a mystery

by 3d printing of course

we turned these into curling trophies for a local dentist team last year.the rock fits inside the crown top, and the crown also fits on the top of the rock.

I'm kinda lost. How are you loosing accuracy of fit is what I can't get.
If you're scanning, you're setting the space programmatically. If you're hand waxing, you're painting die spacer on the die.

Are you seeing problems after milling/casting/pressing/printing and trying to do this to track them down?

By the way, I use Quick Check spray. If you turn on the suction unit and spray into that, there's no mess. I think Vacalon makes it now, used to be Ney.

if your talking your castings. Check your liquid to water ratio for your investment. more liquid less water makes it more loose.

And in lab temperature changes from seasonal variances will cause a change as well. Tracked down a problem to an office storing their imp materials in a cabinet mounted to an exterior north facing wall. That one took a bit.

I just ask what products / methods you use when you need it
Hoping to learn something.
It is nice to see that you pay so much attention to the that you do not have to accurate fit the crown

If they don't fit, theres a problem. Fix the problem, not the crown.

When hand waxing with paint on die spacer, you can see the spacer get abraded in the trouble spot if it catches, but usually it's expected if you're accustomed to the doc and his trouble with dexterity in preparing a tooth. Otherwise, a hand waxed crown/coping should be a slam dunk/home run/touchdown (pick your sport) on fit if your dip wax viscosity, temp, and technique are in tune with each other.

I can't speak to printed at all, nor too much about milled as all the ones I had in my hands came from Mahwah, NJ and seated firmly, but almost only on the margin and incisal/occlusal. And the implant company making them didn't care a great deal about that, but it's all we could get.

If you are having issues, give some details we can work with to help you.

Metal frameworks i use are SLM. And it fits well.
But earlier I used to milled and sometimes, in large bridges, i had to do small points.

I think to have the best fit, always worth checking.
There are sometimes points to improve
