I spend a lot of time, too much actually, doing fine adjustments to my zirconia crown margins. I'm trying to get them to be as good as my cast margins which are nuts -on. Is there anything I could be doing to improve them? I use Exocad, Medit T500, Top shelf crazy powerful computer, VHF K5+mill, Only fresh VHF burs, Talladium Dura Rock die stone and or fuji rock weighed and measured, all work done under a microscope. properly dried in a toaster oven, sintered in well calibrated Dekema with long slow progragram. Is this just as good as it gets? The fits I get on for example Straumann Ti bases are excellent. The impressions I get are also excellent but human preperations always have little variables that the software always seems to smooth over. I always try to buy the best equipment and materials available. Ultimately I get them to fit well but I would like it to be with less effort. Please help me, I cant be the only guy concerned about marginal integrity.
