What would you do ?

[zero_zero]

Got this scan the other day -- it looks like somehow the Trios glitched and did not mesh the detailed parts completely -- , the office tried to resend it a couple of times with the same results. I suggested to bring back the pt. for a new scan or PVS, olny to find out the pt. lives two and a half hours away, and she won't make an extra trip for that. "-You gotta do something", they said... What would you do ?

LOL, is it like this on the doctors side too? If yes then it's on him to make it right. I would't touch the case, unless your working on lower anterior teeth and then it doesn't matter.

Ask dr to make a standard copy and trim around the edges so that the copy file has a slight change from the original.
Is this converted into exocad?

Sorry, Looks like its on your end.

No, 100% the file is messed up man. Lots of bad edges where missing data should be.
We see this when file-transfer is not finished and the connection is lost. Missing info.
We are trying to repair the points back into a continuous mesh now. Maybe works?
Taking a while....PC is on fire. lol

If you change rendering properties to show triangulated mesh, then you quickly see the issues.

10,000 holes and 10,000 bad edges all over the place.

Trust FF experience, I just threw the file in my non-dental viewer.

Just do the best you can.

Nope. This is Meshmixer's view.

 

[Farrah Fawcett]

We are running the mesh through Materialise Magics "Shrinkwrap" operation.

First time we try.

Email. Show and tell. redo. Nothing left to do unless you like games of chance.

As I said also....the original mesh is probably OK. Somewhere along the way, the file was transferring One PC to ? and connection cut short before transfer finished.
Go back to scanner and re-send should fix it.

Agreed..i was just checking mesh.

Thanks for agreeing with me.

It shows up in Exo the same way, 3OXZ and exported STL as well.

If they can make a slight change to the original and resend it should be fine.
Probably someone was surfing porn in the other office.That would explain the cluster fark

Yeah, show a pic of mesh and pic of Meshmixer.

They left for the long weekend already...

After digging through the net for hours, I came to a solution... I knew I needed a feew beers to clear my head. It looked like the vertices were all there, only the facets were missing at some areas. After importing it to Meshlab, I started by getting rid of the single large triangle on Q2.


Next, I exported the point cloud only , then re-import it again


Next I used a function to recalculate the normals for each vertex, need to be able to re-mesh the data. The "hairs" are the normals



Meshlab has a convenient function to recreate the mesh called "Screened Poisson Surface Reconstruction" which does the trick, although it takes a few minutes to compute.


The result:


After inverting the normals:



Turned into a solid model with Meshmixer... now's off the the printer and I am left to enjoy my holiday
