Ideal Model Systems & Worthless Dowel Pins

:eviltongue:
i've already wasted my time w/ you on this...:heeeelllllooooo:

I will either have trays used for my model work during the holidays or shoot my wife.. For some reson theats to fire her don't work.. Wearing the pants in this lab has no meaning..
Can't even get Respect in my own lab that she thinks she's part of ..

renfert top spin

bi-v pins with metal sleeves. we'd order the plastic sleeves but our supplier can never seem to keep enough of them in stock for us.

works for us.

theres a Korean pin system, i'll have to find it for you guys, its basically a + shape, with matching sleeve... EDited to add: found you a link!! http://www.corident.com/eng/product01.html?mode=view&item_id=18&cat_num=005000000

works MIRACLES for lower anterior veneers. we can get super super thin dies out of it.

Doug you are completely right on ! Teeth are mobile, temps will move teeth or wear in time of final insertion. I use solid models to seat after the pinned model is completed and the contacts are always tight. I often find contacts being on the light side at the time of insertion but it's better I suppose than crowns fitting so tight that the Dr. cannot seat them. Every crown will differently.

for those of you using plastic sleeves;
One of the mistakes techs make is using the steam gun right at the nozzle tip to extract debris. Many times this excessive heat is enough to create a distortion of the pin seat. Back off a little, it will still get clean and keep it's accuracy.
Also pour your solids ASAP after you remove the first pour from the impression. Most stones are not done expanding in an hour or even two or three.

 

[capickettcdt]

ALSO;
Same goes for base stones used. Find a low expansion stone and let it finish expanding BEFORE you cut your dies apart, not just as soon as it is hard enough!

Thanks, I didn't think about the time/expanding- with flow stone. ... duh

Six years has passed since the last post in this topic.
Something has changed about the models?

On another topic, I read that some people do not even make separated models, die stone models for Cad Cam.

I used to use giroform / zeiser system.
But I discovered that the Fino Quick Evo system is more comfortable and faster.
Saw cutting is easier because there are no pins you can cut.
What models system are you use ?

 

[2th-man]

Are these available in the US? If so, who sells them.

Thanks,

Forget those pins man, those bloody things are holding you back.

I use solid models only except for special implant cases.

but but but how do you do it subgingival ? ? Gingiva mask.

How do you scan dies when they are too close together ? separate die additionally

If you pour twice the model, you prepare stumps(dies) solo, then you will not be doing it faster than this fino quick.
Work comfort is better, and everything fits.
But I can be quite wrong

Sorry but i could not find anything in u here in usa. only this http://www.hellotrade.com/igc-technologies/siladent-model-system.html
This system comes in a version like my one (evo / eco) and a slightly more (plus) version.
It is sold by three companies. Fino (DTshop) as Fino Quick, Siladent and hinrichs-dental as a profident 2010

Two pours, one dies one solid model. Faster, better and less expensive. Benefits of separated model with the solid model for contacts and occlusion. No model bases or the pinning nightmare to deal with. Developed through optimizing process time and material expenses.

Just G2 I was thinking of choosing this system.

Terrible impression For Exercise Purposes.
You can cut really thin bars.Super useful while making models of lower front teeth

my point exactly.

we had one when i worked at aurum in Toronto. was great.

Long bridge with subgingival preparation and multiple not very good parallel stumps, where some are too close

One Example: Majority of cases are single unit, yes. It is faster and more reliable to trim a die without navigating between adjacent teeth. Focused on just the die. Similarly, is faster and more reliable to cut out multiple dies from a die pour without dealing with the pin locations, etc. Focused on just the dies and margins. Solid model is the die locator by merging model scan to die scans.

Some special cases I use separated model, but 98% are solid.

 

[Jack_the_dentureman]

Yes. All the pins is a really painful affair.
Now, just spray a gray plate with separator, cast a model, cut, tirm and rady to go. do not wait until the plaster will harden the second time (20 min ? )
But surely You are right, it is more expensive I paid for this system, after converting it into dollars, 235$ (You reuse plate multiple times)

Sometimes when there is more work, there are too few plates.
I have to consider the way You use it.
