Dental-Occlusal guards poor fit after switching from clear V1 to V2

Form 2

I had finally dialed in the fit for Clear V1 and then received V2 and used the same settings in our design software(exocad). The only setting I’ve modified in exocad is the undercut from 0.1 to 0.05. I’ve tried the same adjustment with the V2 but doesn’t seem to help. The guards are too tight and I cannot seat them on the teeth without a lot of adjustment and by then it no longer fits well enough to stay in on its own. Frustrated!

bump.

I use the V2 and fabricate the guards in Blue Sky Bio with the surgical offset at .10mm and keep undercut. There are some cases where I smooth some of the undercut when I transfer it to meshmixer but typically they will have a subtle posterior ‘snap’ in which has so far worked.
