Removing a Zirconia Crown 

I loved the outdoor scenes, Dr. Klim! Great presentation and video!

Thanks for the video. You are grateful for many things, and I am grateful for being able to learn from your experience. I wish you a soon recovery of your hip. Best regards from Chile. César

Simple physics, ++ Surface area = ++ retention like what it was with the large amalgam restorations

Nice Video But Video SEO Score Very LOW

The video is called removing zirconia crowns..... But the video is about creating undercuts...getting retention and cemention of crowns... So I'm wondering if you had tips and thoughts about actually removing zirconia crowns. That said, 100% I find section and crown split and DO NOT BOND bc a few zirconia crowns I've had from other providers have had to be sectioned into like SIX pieces to get all of it off.... But also, with a good prep, good wall height, good ferrule if a core etc I feel like an RMGI is MORE THAN adequate to keep a crown on so I don't really see the need to bond??? And I'm wondering for you think sometimes even with an RMGI do you get some bonding if there is a composite core (I personally think you do- but unintentionally!!! Just polymer chemistry doing its thing).

Does the laser work thru zirconia?

With short clinical crowns less than 4mm do you feel the undercuts in the intaglio are sufficient to retain these zirconia crowns?
