Exocad all on 4 pmma gingiva merge error

[NoName]

Hello, this is first time I'm making pmma all on 4 with gingiva and I got this weird error, searched it on google, some guy had the same problem, but there was no solution (pictures I uploaded are his, not mine). it says "missing: error merging virtual gingiva" also just like in the picture it says something about tooth 16 (17 in picture) and I don't get what am I doing wrong.

you need room underneath the teeth to put gingiva so number 1, cut some room under them. 2. ensure each tooth has a uniform surface, not wavy or impeded by some sort of hole or triangle error in the stl. 3. the border of the pink must be a minimum distance from the tooth, it cannot overlap.

So far no luck..

1. Cut some room under teeth - you mean the space between rean gingiva and anatomic teeth? Because I have done that, there is space

2. Also done that, teeth are smooth

3. What do you mean exactly? Virtual gingiva is not very thick, I don't need much gingiva, so it probably is at minimum already. Also anatomic teeth and virtual gingiva will touch..I think..I can't just leave empty space between them, how would it merge

Also I don't really understand the error itself..and why just tooth 16? Is it because merging starts from 16 to 26? And since it's the first one - the whole merging stops? Because other teeth would probably have the same error

Maybe you will spot what am I doing wrong easily..because I have no clue

gingiva has to wrap around tooth 16, extend it or draw the border further.

Have you done the virtual wax up bottom yet? Then you need to calculate waxup so it becomes one piece. Then you merge restorations

Solved it, turns out I had to select in dentalDB anatomic waxup and pontic waxup instead of anatomic crown and anatomic pontic, so now it works fine, but tbh I still don't see any sense in that, I mean why would it matter..but turns out it does
