ORIGINAL QUESTION:

I would like to ask the practitioners, who used (played with) a Structure
scanner ( <URL Redacted>) for foot orthotics
and AFO-s. Outcome? Accuracy? Which labs fabricate using such digital file?
Also, there is a glass scanning stand for AFO featured in the video - who
sells that device?



RESPONSES:

I don't think the base was made in multiples, but it would be great to
know. We have made a equal base and it works well, the problem is the
ability to get a accurate scan with a leg in a corrected position.

We use the Artec Eva scanner and it is amazing. Problem is that it is still
very difficult to cast in a neutral position. Unless the limb is simple and
your only casting for ankle stability or foot drop.

The problem with lesser scanners is the accuracy. Which is important to me
for foot orthotics and AFO's. For a TLSO or equal it's fine.



Our lab uses and accepts .stl’s from structure scans. Our accuracy and
out-of-box fit is pretty incredible with decent scans and good
measurements. I personally don’t use the stand for AFO’s and get great
results. High-tone patients or uncooperative/fidgety Peds are always
difficult, but the scanning process on an iPhone is lighting quick so you
can get several and specify finished measurements for a great end result.
Much quicker turnaround also with email, no waiting for UPS! (Ultraflex)

Techmed 3D has a nice stand but last time I checked with them they wouldn't
sell it unless you bought their software. If you find an AFO scanning
stand, please share

I use Digisan3d as the app. It natively exports STLs I’m appropriate scale
and the scans are super clean.

I have one and used it for a burn face mask. The first result was terrible
resulting in a mask way too large. After many discussions with the lab it
came out ok. I think the software should have a fixed dimension object that
is along side the scan so they can calibrate the two for proper dimension.

I asked Oww about scanning for a custom liner and was told it is still
better to send a cast (not sure if they still feel this way or have
perfected the technique)



We use it for our own program through Orthomerica and it’s great! Glass
stand would be tough as the posterior portion of the scan is critical and
difficult to acquire. We use a field goal type stand that we custom made.

We use the structure scanner in our clinic here in Australia and we even
make and sell a scanning plate for it. I know Tech Med sell one also.

The standard file format it produces is the OBJ file but some apps allow
you to send it off as an STL file also. We central fab in Australia and
except either file for Foot orthotics and AFO's so there should be
companies like us over there that do the same.

They are not as accurate (+/- 2mm although the accuracy also depends on how
far away you are from the object) as the more expensive White light
scanners and Vorum scanners but do the job if you are touching the water
with CAD CAM and scanning feet or foam impression boxes or even for AFO’s.
The Willow Wood app is a great app for scanning but you would need to work
out with your central fab places to what they will accept an contact them
for pricing. Here is a link to a video when scanning in foam impression
boxes and importing into cloud base foot orthotic software.

It's a $1,200 scanner it's not very accurate at all there are too many
variables



 THANK YOU ALL, WHO RESPONDED!
