Analogs for 3D printed implant models

[rkm rdt]

Stock analogs do not always have the internal anti rotation in alignment with outer due to the nature of the broaching process which is arbitrary

Stock analogs would be cheaper than a proprietory analogs from the milling/printing center.

By printing an abutment transfer jig you accomplish 2 tasks at once.

1. the jig is used in conjunction with a scan body or closed tray impression coping to position the stock analog into the socket of the printed model.

2. once the case is completed , the dr can use the transfer jig to place the abutment.

Of course the dr could always use a small thermoplastic jig to position a closed tray impression coping introrally at the same time as the ios.

given that you can download a digital file of an implant analog + interface from medentika, maybe pre-printed analogs could be a solution. if you try to print the digital file you download from medentika, will it interface with the correct interfaces from implant direct or NTtrading ?

if so it would be a relatively simple matter of creating the hole in the scan for the analog and a jig to position it. but if printing the analog is essentially do-able, then printing the entire model complete with analog should be a snap.

you would just need to use a CAD program that is not what we currently use; something that can add two stl files together, and output one.

Makes sense luke but wouldn't screwing a ti abutment into a printed model analog be a challenge?

Can you print such a fine thread pattern ? ..and would it survive the lab fabrication process?

I think a stock analog would be my preference.

I think the jig idea is doable because i watched a video from a milling center in the states that printed a solid model and a separate single die attached to the model.

It only makes sense to print a jig instead of the single die for an implant case.

 

[CoolHandLuke]

would depend on the quality of resin you print and how gently you treat the case.

mind you, yes you can print a thread that small, but you could also print a screw, and not flub either part.

but for this you would need a MASSIVELY expensive and accurate printer.

If you want the medentika analogs made for about 20usd each, let me know.

Call 3i-Biomet and ask them to give up the goods on how they do the Encode...lol

Encode is no problem to duplicate. But, there is a patent on the process.

 

[rkm rdt]

No, a dowel pin will not work due to the taper. The taper will result in some potential error in the vertical location of the analog. There will need to be a shoulder to act as an exact vertical stop built into the design.

Bob, i just saw one of your printed models which looked impressive. I was also just informed that Core3d are making implant models.

Any updates you can share?

 

[BobCDT]

They keep telling me two weeks.

Hi.
We found solution.

 

[rkm rdt]

Can you elaborate Tero?

 

[keith goldstein]

Hi.
We found solution.

please tell us about the solution
what analogs did you use
what printer
are you selling/offering the design software to create this or provide a service making them
I am in the USA and very interested

We work with 3shape Trios and 3shape Dental Systems.
Printed models stl files are made with Modelbuilder. We have create implant library for this solution and this library give us option to mill abutments and implant bridges based Trios intraoral scannings.
These replicas are from Dess.
We are still working on this technic but so far results are quite promissing.

We are millingcenter and distributor for 3shape and Dess products in Finland.

Can we see the underside of that model Mr Rakkolainen?

 

[Tero]

Hi. Sorry about delay...

Please find the picture. From hole on bottom we can control that replica is in right position.
This is now first evolution but we are workin on next one already.

You guys are awesome!!

Can you provide an English translation to your web site? I love the visuals.

How did you attain the high gloss to your digital models and skull print?

I cannot wait to see the next iteration. We offer DESS in the USA.

Boy was I off on a tangent with this thread.
So much has changed since our last posts.

LOL, I was even agreeing with *** at one point.

Of course a speciallized analog is the way to go . Core 3D analogs slide in to the model from the bottom however they can also slide out when you are working on them. We had to lock them in with Triad.

Nt-Trading provide an excellent analog that inserts from the tissue side and locks in with a nut from the underside.

Our results have been excellent so far. Cost is reasonable.

Hi.

Does anyone know from where I can buy analogs / replicas for 3D printed models?
We have own 3D printer but no working analogs so far.
Stl files of these analogs would be great too, but not nessesery...


Thanks

Core3D is doing it already. Call and ask for Mark Ferguson.

NT-Tradings implant analogs are ready to go: Link

Its a nice system and works with most major implant types.

 

[CoolHandLuke]

lets just say you can stitch the abutment design to the scan, and in doing so create a model with a die instead of an analog.

would that be useful to you?
