I had the opportunity to try out the .STL export function in software 4.5.
Under the export tab, I selected highest resolution.
From here, I imported the file into Meshmixer. A model .STL for CEREC chairside does not have a base, it's just a shell, so any holes in the model have to be closed and a base added... this is easily done in Meshmixer.
The .STL file is then imported into Preform software for adding supports and printing.
Technically, you should use Dental Model resin to print these, but I had gray already loaded and wasn't concerned about checking the margin accuracy as I wanted the model only to help with contouring.
It's really a bigger advantage then I realized to be able to look at the incisal edges and contours on a model. People like Kris and Ross can do this stuff with their eyes closed, but I need every bit of help I can get.
Immediate post op. Pt. was happy and I had much less intra oral adjusting to do.
