Without imaging, you’re basically guessing treatment plans — and that’s never a good thing! To know the best possible treatment for your patients, you need MRIs and CBCT. And to help you get started, Kirk Behrendt brings back Dr. Drew McDonald to talk about the pushback with imaging as well as the benefits and value they have for you and your patients. Don’t go into treatment blindly! You can have clear images that present the truth. To be a better clinician that changes patients’ lives, listen to Episode 403 of The Best Practices Show!
- A clear image will help you see under the surface.
- MRIs can show the severity of joint instability.
- CBCTs and MRIs are safer than ever before.
- Having images can increase case acceptance.
- Imaging will lead the way to being better clinicians.
- “The biggest thing of why [it’s important], for me, on what we’re talking about with imaging is that it’s the truth. You can’t fake that. It’s right there in front of you in the cold, black mirror that you’re looking at on that X-ray or that MRI. And ultimately, it tells your patients the truth. But for me, whenever I started going down the road of, ‘Okay, let’s see what’s under the surface. Let’s see why this patient isn’t responding the way that I anticipated,’ that really shed a lot of light on what are the true problems here.” (13:19—13:49)
- “The other unpleasant conversation that you get to have with patients when [relapse] happens is, ‘Well, I thought this was going to stay. Why didn’t it?’ And it starts to look like you, as the doctor, didn’t do your job. Well, no. If you did your job at the front end and diagnosed and said, ‘Hey, we need to take care of not just the teeth but these issues to keep this stable,’ then you really did your job and you’re in the clear as a doctor.” (14:21—14:46)
- “Right now, in dentistry, the biggest evolving part of this profession is on the imaging side. I think we’re in a huge revolution of how we’re going to do dentistry, where everything is going to be in 3D and people are going to routinely do MRIs, not just TMJ specialists. In my world, I think I’m one of the few orthodontists that do it. But it’s going to be widespread. And honestly, it gives so much value to the patient. We treat them to the highest standard of care possible instead of limiting what we could do.” (16:15—16:48)
- “I started looking at my 2D X-rays and then looking at the 3D and saying, ‘Well, I can kind of see this on the 2D.’ On a lateral ceph, you can see adenoids. It’s clear as day. You can see tonsils clear as day. So, you don’t necessarily have to be totally in the 3D world, at this moment, to be able to start looking for the things that we should be looking for. I mean, on a pano, you can see turbinates clear as day on a lot of patients and see noses really well. And also, the biggest thing, you can see joints. So, just in our every day, what you take as a general dentist, what you take as an orthodontist, those images are still very valuable if you know where to look besides just the pearly white things in this little area right here.” (18:37—19:21)
- “I started saying, ‘Okay, maybe I should be doing [imaging] on a few more patients,’ because I’m starting to see maybe this is part of their problem. But I was recognizing surface issues like narrow palates and things that then I go, ‘Well, maybe I should see if there’s something causing this under the surface.’ And then, at that point, you show the patient, and they go, ‘Yeah, let’s follow up on that ENT referral.’ I never thought, as a dentist, I’d be writing as many ENT referrals and chiropractic referrals and TMJ stuff that’s never thought of as part of your world, but it certainly is.” (19:28—20:04)
- “One of the most valuable pieces of having imaging behind it is I could go to the ENTs and say, ‘Hey, here are these pictures of this patient’s nose. This is helpful for you to diagnose and make a plan, and I’m going to send these on every patient that I send you to. Is this helpful, and what do you see?’ And I talked with one ENT, in particular. Initially, they were like, ‘Well, I never routinely had those in front of me on these patients. But now, I see it.’ And so, then the imaging side really did start to open up other people’s eyes as to, ‘Okay. Well, that’s not just wishy-washy. That’s hard and fast right in front of you with that image. And so, what do we do now?’ Instead of guessing or saying, ‘Let’s watch it,’ [it’s] like, ‘Hey, we can see the enemy. Let’s go for it.’” (21:06—21:52)
- “At the end of the day, [imaging] really does open your eyes on the airway front, especially as to the health benefits that we can have for these patients, and that we can really create a better systemic situation for them, not just a teeth situation up here.” (27:05—27:21)
- “I had to have jaw surgery. I was so Class III, just a classic mouth-breather, tongue-tied patient. And essentially, [when] I was in my 30s and had jaw surgical correction and a nasal septoplasty, I was like, ‘Wow, I can actually breathe through my nose. This is great.’ Ultimately, I lived my whole life like this: I couldn’t smell coffee. I couldn’t do this, this, and the other. But I didn’t know about that. I didn’t know I needed septoplasty and things done until I saw it on the CBCT, and I was like, ‘Damn, no wonder I can’t breathe.’” (28:21—29:00)
- “The other big thing, back to the inflammatory side, you don’t know how inflamed that joint is until you see it on the MRI. And there are some people you’re like, ‘Damn, we’re fighting a forest fire here. There is no way this splint is going to be good for you, or the right kind of matchup. We need to manage this this way before we get into ortho.’ And for some patients, it says, ‘Wow, you really do need a surgical procedure,’ like what Dr. Mark Piper and Brian Shah and everybody pioneered and do. And it changes people’s lives.” (31:30—32:04)
- “Sadly, I feel like in a lot of ortho right now, there’s pushback on imaging that there shouldn’t be. And some people get thrown under the bus for taking CBCTs on patients as part of their ortho workup because a lot of people think it’s over-irradiating a patient. And in this day and age, the CBCT machine that I have and the ones that are coming out that you would buy if you’re buying a new one, they have less radiation than — I mean, if you take a pano and a ceph on a 2D thing, my CBCT currently has less radiation out of it that I can see joints, airway — everything under the surface on — than those two old images I used to take.” (35:34—36:19)
- “‘At what level do you feel comfortable going in blind on a case?’ is what I ask those doctors where they’re like, ‘Why are you taking the CBCT?’ I’m going, ‘Well, I want to know everything about this patient. I want to know what’s going to screw up my nice result. I want to know what I need to be encompassing with my treatment. And ultimately, I want to show the patient too. So, can you get that off your pano and lateral ceph? If you can, good for you. But I need this level to be able to operate at the standard of care I want to provide.’” (36:21—36:54)
- “One of the biggest, most important things I think we all need to embrace in dentistry, not just ortho, is how much we can be part of such a bigger picture for our patients, and that the imaging under the surface allows us to see those things that we can be a bigger part of. And so, on that note, we all need to be very confident in reading CBCTs.” (37:56—38:17)
