In the first ever 4K Ultra HD Live Chair side clinical procedure, Dr. Hornbrook takes you through the removal of old opaque Porcelain Fused to Metal Crowns from 1958 on Dr. Dale Brandon of Orange County California and replacing the old PFM’s with New anterior esthetic zirconia crowns with high translucency (KDZ Bruxer® Aesthetic from Keating Dental Lab).
Included in this remarkable clinical video series is “how to take a prep shade”, esthetic crown material options and how to use them and finally wrapping up with the Replacement of the old anterior crowns with solid zirconia high esthetic restorations.
The Patient (Dr. Dale Brandon) also has one root canal tooth, but most of the grayness is coming from that gingival third where he has some recession due to the inability for light to penetrate through that porcelain-fused-to-metal crown and light up the root.
Dr. Hornbrook starts this restoration in Part 1 by cutting of the old porcelain crowns and actually performing some conservative, very minimal prep veneers on his lower interiors to improve that incisal plane. Utilizing some of the new high-translucent monolithic zirconia strongest material we have in dentistry which is what we call the KDZ Bruxer® Aesthetic and looks as good as some of our glass infused ceramic and even our lithium disilicate.

Video Tutorial Transcript:
Dr. Hornbrook: Hello, I’m Dr. David Hornbrook, Clinical Director of Education at Keating Dental Lab, here in Irvine California. Today we’re going to have a great experience. This is Dale, and in fact Dale’s a dentist and he has some porcelain-fused-to-metal crowns that were place, we just decided in 1958 and it’s 2015 now, so that’s 57 years. They’ve done their service but, they’re out of here. They’re opaque and we saw, even today with porcelain-fused-to-metal crowns. Opaque, we got the grayness, it’s caused the roots to become gray. He’s got one root canal tooth, but really most of our grayness is coming from that gingival third where he has some recession is due to the inability for light to penetrate through that porcelain-fused-to-metal crown and light up the root.
So what we’re going to do, is we’re going to cut these off and we’re actually going to do some conservative, very minimal prep veneers on his lower interiors to improve that incisal plane. We’re going to take these off, temporize them and then next time, we’re actually going to utilize some of the new high-translucent zirconia. Monolithic zirconia, so this is really the strongest material we have in dentistry, but the new high-translucent, which what we at Keating call the KDZ Bruxer® Aesthetic, looks as good as what we see with some of our glass infused ceramic and even our lithium disilicate. So we’re excited about that, so let’s go ahead and get started.
All right, so we just finished with Dale, we cut off the two existing PFMs and he had some decay an existing class IV actually, with a minimum pin that he thought was in there since 19- well before most of us were born, but anyway, we went ahead and prepped those for very very conservative crowns as well. So we’ve made Luxadent temporaries, these will be on there for about two weeks. Why don’t you go ahead and take a look. Big difference.
Speaker 2: Big difference, yeah.
Dr. Hornbrook: Remember he hadn’t had his crowns- he’s had the same crowns for 57 years. This is going to be a little bit of a shock.
Speaker 2: Wow. Yeah.
Dr. Hornbrook: [00:02:00]Big difference.
Speaker 2: Big Difference.
Dr. Hornbrook: And we’re going to put conservative veneers on the lower to bring up his plane from just years of wear, so we’re going to build that plane up and give you a nicer incisal plane. Big difference though.
Speaker 2: Sounds perfect.
Dr. Hornbrook: Smile for me.
Speaker 2: Yeah.
Dr. Hornbrook: Smile. Yeah. Look nice. Cool. How do they feel?
Speaker 2: Feel pretty good.
Dr. Hornbrook: Good. Okay, good. All right Dale, you were a great patient I appreciate-
Speaker 2: All right, well thank you.
Dr. Hornbrook: Okay, we’ll see you in a couple weeks then.
Speaker 2: All right, we will, we will.
Dr. Hornbrook: Okay. Awesome. And in two weeks we’re going to go ahead try in the restorations and, knowing Keating Dental Lab, they’re going to look awesome. I hope you have a great day and I hope we’ll see you at one of our courses sometime soon.
