      • How CT Scans Help Us Help You


        from Atlanta Dental Spa Added 0 0 0

        If you're ever walking around our Buckhead office, this is a pretty common sight, me sitting here at our CT machine planning out a case, figuring out how to protect our patients from any unnecessary, risky outcomes. We always enter into every procedure knowing our final game plan before we even start. And that's really critical whenever you're doing any aspect of dentistry, whether it's creating a blueprint in porcelain for the veneers that are coming or doing a virtual surgery on a computer before we actually do the procedure in the mouth. So that way, we know everything that's going to happen before it happens or at least as much as is absolutely possible. So it's a really powerful software and a wonderful machine. It allows us to take three-dimensional images in three different sizes, where we can focus on a tooth or two. We can look at a quadrant or a full arch. Or we can look at your whole mouth at one time. And there's lots of different reasons that we do this. We look at root canals to make sure that they're healthy and look for variable anatomy that makes it very difficult to do that procedure well if you don't have this kind of imaging. For every implant procedure, we're going to do this every single time so we know exactly what size implant, position, angulation. It allows me to do a little virtual bone biopsy, so I know the density of the bone, so I know what protocols to follow. We can find pathology. We can look for infection. We can evaluate the nerve in relation to your wisdom tooth so that if your tooth is in a position and a place that makes it risky, we know how to avoid any kind of trauma or damage to the nerve. So it's a very helpful thing for us on every level. It's a safe thing for you. Also, speaking of safety, a lot of people are always concerned about the amount of radiation from a CT scan, because they think of a medical CT scan. Our CT scan is about one thirty-seventh of the radiation of a medical CT scan. We don't need the level of resolution that they do in a medical CT scan for what we're doing. We have very high-definition stuff here that gives us exactly what we need at such a low dose that that part is pretty negligible. If you consider dental X-rays from back 10, 15 years ago, just a handful of irregular checkups with X-rays is about the same as what our current three-dimensional imaging is. So don't let the radiation part be a holdup for you, because it's so critical for good, proper planning to keep you safe and make our treatment predictable.

        • What is a CT Scan?


          from Atlanta Dental Spa Added 0 0 0

          I have to talk about bone grafts very frequently on a day-to-day basis here. And the reason for that is because we want to make sure that you always have all the teeth that you should have. And when you lose a tooth, that bone that used to hold that tooth starts to dissolve away. It exists only to hold that tooth. So when the tooth's gone, it starts to atrophy, and we start having issues with putting an implant there to give you your tooth back. So that's why we talk about bone grafts because if you don't have enough bone, we can generally rebuild enough to allow the implant to be placed where it should be to give you the tooth that you need. But there's also a lot of different types of bone grafts, and people always want to know, what am I talking about when I say bone graft. And there's a pretty big spectrum there. The easiest, most straightforward, least expensive, least painful kind of thing in the world is when the tooth comes out, that very same minute, we put in a bone graft. And that means we're just filling the socket that used to hold the tooth with bone. And the analogy that I give my patients on a pretty daily basis is, you know, if I ask you to build a wall and just gave you nothing, you'd have to wander around and find rocks and assemble your wall, right? Or if I gave you a pallet of bricks and said, "Build a wall" you can assemble a really good one, really quickly. That's kind of what I'm doing for your body. I'm giving the bone right there all of the materials it's needing to build you good quality bone in an adequate amount to give us a really good predictable implant site down the road. So that's what we call a site preservation, meaning we're preserving that bone that would normally shrink away so that we can put an implant in pretty shortly thereafter. That's really, really common and highly recommended. People are always like, well, am I a candidate for that? Pretty much everybody's a candidate for that. And then they always want to know, well, what is it, you know? And there's lot of different kinds of bone grafts. Bone grafts can come from you. It can come from a cadaver which is also pretty common. That always freaks people out a little bit. Don't sweat it. What it is, is it's very sterile bone chips that technically, yes, they do come from a cadaver, but when we put it in there, I'm giving you that pallet full of bricks. Your body will break that bone down and re-assemble it as part of you. So if we came back and took a biopsy of that bone six months down the road, it's you. It's 100% you. You're not walking around with Joe over here. People are all so weirded out by that, but it will be absolutely your bone. Does it have to be cadaver? No, it doesn't. There's also other types. We can do what's called a xenograft which is just a fancy way of saying from a different species of... Bovine is really common, pig bone, whatever. If that freaks you out too, there's synthetic grafts. That's where we use, pretty much, the mineral components that bone's assembled from. We put that right there, and your body can build it too. So, you know, whatever your hang-up is with whatever the type of bone graft is, let's talk about it because we do have a lot of options. And we can make that a non-weird event for you because it's a really important thing so that you get a good predictable outcome. There's also more extensive kind of bone grafting that it's hard to explain it here when we're not in person looking at your scenario, but know that if you're missing width, if you're missing height, if you have a large sinus where an upper molar used to be, we can fix pretty much all of those things. So come in. Let's talk about it and just know that about 60% of implants requires some level of bone grafting. So it's really common, it's not a weird or hard thing. We do it routinely, and we can talk about what fits your scenario best.

            James R. Jett, MD, of National Jewish Health, discusses his study of the early CDT-Lung biomarker. His hypothesis: When used in combination with low-dose CT in screening of a high-risk population, this biomarker would increase the detection of early stage lung cancer. (Abstract MINI 12.11)

              from Abrazo Community Health Network Added

              An avid hiker and world traveler, Ann worried that severe back pain meant she would have to give up her favorite activities. During the past 15 years, Ann endured multiple surgeries and when her pain became unbearable, she spoke to her spinal surgeon. Ann’s anxiety over needing a new operation turned into excitement when Dr. Dohring told her about the new robotic spinal surgery at Abrazo Arrowhead Campus. As Ann heals from her robotic spinal surgery, she looks forward to adding back some of her favorite activities that she had to cut from her life. Abrazo Arrowhead Campus is the first and only hospital in Arizona to use the new Mazor Robotics Renaissance® Guidance System.

                    from AMNH Added 60 3 0

                    Some carnivores eat only meat, while others are more omnivorous. To understand how and when these differences in carnivore feeding may have evolved, Museum paleontologists captured X-ray scans of skulls from living and extinct species. They reconstructed the skulls as virtual models and designed feeding simulations, to test the relationship between skull biomechanics and diet, shedding light on the evolution of feeding specializations and their distribution in the carnivore family tree. Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History.
