Looking for an easier, less stressful way to remove Bruxzir crowns. ■

Don't place them ... sorry couldn't resist. The profession really needs to evaluate what we are
doing with restorative materials that make retreatment so difficult. ■

Guys, it's really not that hard. Honest. You want to use a fine diamond, red stripe. It's counterintuitive but that's what to use. Make a slot with that then use a Hu-Friedy crown remover.
Do not use any kind of a coarse diamond. Just doesn't work. ■

Fine diamond. Not that hard. Would prefer taking off Luted Zirconia versus bonded e.max
every day. ■

Fine diamond. Up buccal and across the occlusal with lots of water and then crown spreader.
Easier than e.max in my opinion. ■

Bonded e.max is the worst. It's like cutting a new crown prep out of lithium disilicate. That
is really hellish. ■

Coarse diamond is fine to use, it will become a fine diamond about five seconds after drilling
on that zirconia. I've only had to cut off one zirconia crown so far. I think I did use a fine
diamond actually. Split it off very easily after cutting a groove from B to O.
Had to replace what I believe was a Procera crown the other day (I don't know ... it was
about a 10-12-year-old porcelain crown, so I'm guessing). Holy crap. Went through three coarse
diamonds, basically had to "prep" the crown off. Loads of fun. ■

Bigger question is: Aren't these being used to resist fracture and thus lowering the incidence
of having to remove them? ■

I haven't seen a chipped zirc crown yet. Now PFMs? I've seen a bunch! ■

The good part about them is they don't bond. Personally, I find it much harder removing a well
bonded e.max crown. Of course, plenty of e.max crowns aren't properly bonded in the first place. ■
