We did a three unit implant bridge twice. We used Ivoclar's Prime B1, Ivoclar's PM7 to mill, and Ivoclar's S1 furnace to sinter. It fractured both times. Any ideas as to what may have caused it. After the first fracture, we thought it cooled too fast during layering. Then it happened again after we took more precautions. We have done many monolithic bridges with no issues. I attached a picture so you can see how I nested it.
