Who here is doing these? Always been warned against it.

Following on from my observations of colleagues doing crowns, I notice an old school dentist using IRM and sometimes even Cavit (when he runs out of IRM) for a core build up. Just tells me make sure it's set hard and it's totally fine. Benefit is it takes 10 seconds to plop in lol, no light curing needed etc.

I've heard of IRM core build ups as a distinct thing of the past. But cavit core build ups - really?

On that note, his crowns aren't failing lol so maybe he's got a point?

This one particular dentist I work with regularly does crown preps without a build-up. He just tells me 'the lab will fill the void space with the crown material itself'. His opinion is that a build-up is not necessary unless there is quite a large structural deficiency. Most important is to round off line angles, make sure prep is smooth and then he says he is good to go. He doesn't believe that a build up would make his crowns better and for that reason, it would be unnecessarily wasting time doing one.

To be honest I've always assumed that doing a build-up is better than not for 'reasons' but his works makes me pause and think.

What do you guys think?

Any place to do a CBT motorbike this weekend?
