Finishing Margins in Dental Restorations

I have a quadrant isolated. Classic FM is playing in the background. The teeth are bone dry. I pick up the air abrasion unit and begin my adhesive protocol. I am well and truly in my happy place! This week we're joined by Dr Ash Lifts - a wonderful, reflective practitioner from The States. We had a great time discussing cusp preservation to material choices for onlays.

I've got my rubber dam isolation and I just enter this flow state. It really is a fun procedure for me because I feel that every prep and something I'll guess today, Dr. Ashley Chung, aka @dr.ashlifts, also says later in this episode that she feels like no two of her preps ever look the same. Jaz's Introduction:And there is a beauty in that. You really have to think before you prep. It's not like making a one millimeter shoulder all day round. There's decisions to make which cusps are in compression, which cusps are in tension, which cusps can you preserve? And that's why all of our onlay preps look different for different teeth, for different scenarios. And it's a big part of why I've been doing this for about six years now. And I just love it. I still love it. I still tell my nurse, Zoe. We have an onlay prep today. I'm going to be in the zone. We'll put on some classical music. I'll have rubber dam on and I just enjoy it. It's usually either classical music or like rock music. So those are my two-treatment music. I used to do hip hop, but then the swear words and curse words, I didn't think that was a good vibe in my patients. So think like, Red Hot Chili Peppers, Foo Fighters, that kind of stuff. Always classic FM, right? It's one of the two. Now in this episode with Ash, who by the way, is just the most humble dentist ever. She's so sweet, she's so humble, she's so caring, so giving. All those good things that we need in dentistry, right? There's too much fake stuff in dentistry. There's too much showing off. There's too much, look at me, I'm awesome. I've got millions of followers and I've got a Ferrari and this kind of watch. Where she is just as far away from that as you can go. And this is why she's attracted such a large audience on Instagram, and I think she deserves all the followers and all the applause that goes with it for all her work that she does. So we need more people like Ash in dentistry, so it was great to have her on the podcast. Whilst a good chunk of this episode was partial coverage,
