So we have had the Edin260VS and a Trios for a while now.
I just want to point out a few issues in hopes someone here has a solution.
But keep in mind I don't expect printed models to replicate what a fantastic impression and stone cast can replicate. And this is only discussing a fully digital workflow from a Trios scan.
1. We were hoping that if we had the contacts perfect on the printed cast, it would be perfect in the mouth.
No, not at all. If we build perfect contacts on the printed casts, they are very open in the mouth.
So we leave them tight. But not a little tight. VERY tight. This is a problem.
For now we are just adjusting our contacts to .01 and trusting this is optimal. And then adjusting the
printed casts to fit.
2. When building monolithic crowns we set our occ distance between .2 and .3 and this has been
acceptable. But when layering porcelain over a zirconia frame, the occ on the printed articulated casts
hasn't been the most accurate.
3. The MED6XX material printed on the 260vs is very soft and leaves crowns bouncing. It also abrades
easily. It seems that no matter how clean we blast or scrape them. There is always more film to be
scrapped off. The abrasion and malleability of the material leaves a lot to be desired.
We are almost strictly keeping the fully digital workflow to single unit cases. But would like to dial it in to broaden that spectrum.
Still, we have been happy with this system considering.
But, what can be done to resolve the printed cast issues?
Thanks.
