[QUOTE="grantoz, post: 257934, member: 2255"] i think you are using to many different products together and no real education .1st your sirona speed sintering furnace scares me its not designed to do a 13 hour sinter cycle which is what i do for all my full arch cases some of which i did by hand milling 12 years ago no failures by the way. 2nd you are heating and cooling your frame to quickly when firing porcelain to them, again its about an hour each firing.i use zirkonzahn everything for these cases all of it is more expensive to use but no remakes of cases in the mouth make things a lot cheaper when you way up loosing clients. I know i sound like im a ZZ salesman but i have followed there teachings very closely i have done a number of their courses over the years and i have sent my staff there as well there systems work and considering they invented the whole full arch techniques i would think you could do a lot worse than start looking at their systems and investing time and money to make your bridges correctly .A few posts on a site like this isnt going to solve you problems i see so many people try and do this kind of work half assed then it fails then it gives Zirconia a bad name. Im sure John Wilson feels the same hes not having probs either for the same reasons, we have both done hundreds and hundreds of these cases with very few problems . [/QUOTE]
