Ok, I know the first question will be. Why are you still doing refractory onlays when we have emax?
The answer is one of my Dr's loves the way they look compared to emax. I have to agree a miultipowder build up on refractory looks fantastic! She will pay extra for them to make it worth my time. The problem is half the time they crack before I get them off the die. Veneers are no problem. the onlays are often very large and should really be full crowns were talking 2.5-4mm thick in some areas. I have fast cooled, slow cooled both crack. I have used Creation CC, Creation ZI-CT, Wieland Reflex, and e-ceram all have the same problem. I use GC orbitvest. 1, Wash bake 2, 1/2 buildup, cut for shrinkage 3, 3/4 to full couture 4, final build and then glaze.
So 3,4 bakes and a glaze bake.
Any ideas?
