Mike Skramstad I just wanted to show a case that just got seated today. It was a bridge from 2=5. I would have preferred implants obviously, but the patient did not want to do the required grafting, etc... to do it. She was rather concerned about esthetics... so what do we do? I don't use e.max bridges in the posterior anymore and the high strength zirconia would have not looked good enough. I could have sent to the lab for a layered bridge... but I tried to use translucent zirconia instead. I have talked extensively about the short comings of this material. Even though the flexural strength of this material I used is 600mpa, there is no transfomational toughening present so it is much weaker than the zirconia that we all use same day. This is Copran Ultra Translucent zirconia from Empire Dental Solutions.
The result was excellent... will it work long term? We will see. The connectors were about 14mm2 on this and it was cemented. I fired it for 9 hours in the S1 furnace (cannot use Speedfire for this).
Just thought I would post as an option.
