Before you click on the document above just a note .... I had noticed when I skimmed it that the last after photos showed the bridge very white and did not match well at all ... asked Mikey about it ..... here is what he had to say.

But that was an experiment that I did at the beginning of the year! At that time the CADTEMP blocks were not available yet, this was the only test block that I got at the IDS dental fair. So we could only do it in 0M1. We asked the patient before and he absolutely wanted it, plus it was meant as a temporary. We did cement it with Maxcem but without any additional bonding, so it would be easy to remove without changing the prep.
What is funny is that he just had his cleaning and checkup a week ago. The "temporary" bridge is still like brandnew! I offered the patient to do a permanent restoration now (PFM or zircon) - he refused. I offered him a free redo in 3M2 (because I now stock these plastic blocks in 1M2, 2M2 and 3M2) - he refused. He wants to keep his 0M1 bridge as long as possible. He now even wants anterior veneers in the same shade...!
