Hello everybody ,
Last week came into the lab a case of a five unit bridge from 34 to 38 of a patient , and the dentist asked for a zirconium bridge with no layering . So I designed the bridge , sent it to the milling center and it was made with wieland translucent zirconium . When the doc had the bridge and put it to the patients mouth with the cement , he instructed the patient to bite , using a piece o cotton between the bridge and the antagonist teeth . And then the bridge broke into 2 pieces . Any idea why that happened? I have small experience with the CAD CAM stuff , i have my scanner like a month . The same doc 2 weeks ago broke an e.max crown of a premollar the same way . Any ideas? Thanks .
