Hey Exocad experts - I have a PMMA hybrid type prosthesis that I am using as a wax-up scan to copy mill out of zirconia. I need a gingival cutback for porcelain. Is there a way to do a controlled cutback line along the gingiva like we do with a veneered tooth restoration? A waxup will allow for copymilling but I miss the reduction window and goes straight to free-form. Free-form isn’t all that precise. How do you guys do that? Is there a way to cutback a merged design?
