Basing and mounting printed implant models

[RileyS]

How do you guys and gals mount printed models with all the digital model analogs open where you’ll be glueing/plastering? I have been using pre poured cast bases and cutting out the area of the analogs. If it’s a case that will mounted to a SAM or stratos type articulator then I’d fill the hole with putty and remove it after plastering like the picture of ivory colored model.
But this case?

Hey Riley

I use these bases on most of my printed models. They come in different shapes and sizes:

SBASE Full Arch Upper Kit

Meta Dental Corp. is an import / export dental company based in New York.

(I buy the 'bare' ones)

I usually don't retract the analogs from the model once it is articulated, except if I recycle them. So, in your case above, I would relive the spots where the analogies poke through on the base and glue it onto one of that plastic bases. The bases can be trimmed, too, if needed.



I realize the above is not an implant model, but it gives you the idea. Hope this makes sense

I think I see how that thing would work.
Wish they had some videos

I think you can add it in your model builder when designing the actual model?

I just cut a groove in the bottom with a lathe disk, super glue a couple of washers in (cut in half or not) and if needed for the access holes, I use white or red rope wax on the areas. I clean those areas a bit while the mounting stone is setting, and once it's set, pull the white wax out with a Buffalo knife to expose the access hole. Sorry, no removable cast to show you, but you get the idea.

Do you have a picture?

Interesting.
Why the groove and washers. I’m slow brained these days and need help understanding

 

[RileyS]

This is what I’m doing and don’t like the time it takes.
Mark and cut areas on bases.
Glue to base
Fill the cut out with putty/play dough
Plaster to articulator
Remove putty

Retention to the plaster, they are smooth on the bottom (from my account) and they used to fall off the plaster bases when articulating, especially the uppers that were totally flat on the bottom. I like to keep the plaster smooth and to the edge all around (I usually don't make bases),so there is no retention in that regard (see my photo in how clean it looks, looks better that way for diagnostic wax-ups as well). What can I do instead that is easier? I suppose I could just superglue them together, but I think I had tried that?

Oh I see. I cut in some lines and cross hatching for that reason. 98% of the time it works every time

Yep, I saw that from your image, and that you are doing the same thing with putty/play dough which is probably less of a clean-up mess than my wax rope idea. I'll be trying that soon, thanks for posting that tip

We print them empty and to mount we make holes manually on the sides, like draining holes for retention.
If not we just use the glued grey articulators not mounted on big articulators
