[QUOTE="Drizzt, post: 273149, member: 4075"] Zirconia can often do than. It is a reflective material so it is not unusual to have a higher value result, especially on posteriors where most of the times there is not enough space. If I have to fully layer a posterior, I am treating my zirconia almost like a e.max LT. I mkae a small cutback, like 0.5, then I stain the zirconia core, and then I am building just with enamel. I am doing this because I want to be safe regarding chipping. The less porcelain I build, the better I sleep at night. If I achieve a A4 with my stains, then almost always after a thin layer of enamel skin I have a nice warm A4. I would use SI-06 inst instead of E60 for instance. It will give it a more warm appearance. Also HT 55 for the cervical. Now if I was building full , I would take my coping, make a wash firing with a mix of D A4 and SP-25, fire it 30-40 degrees higher than 1st bake. That way I ensure a nice chromatic base, and fluoresence from the margin powder. Then proceed with your build up, DA4 , the appropriate OD on the occlusal for depth, the HT you like etc . Hope it helps [/QUOTE]
