Which Field Of View Is Right For You?

If you are wrestling with the idea of adding a new 3D imaging system to your practice, there are a few questions you should ask yourself:

  • What do I want to do with the information that the new system will provide?
  • Am I interested in return on investment (ROI)? (Of course you are, but is there more to it than that—like broadening your skills as a clinician?)
  • Am I expanding the capabilities of my practice in the future?

How you answer these questions can help you determine which field of view (FOV) is right for you and which imaging system best fits your needs.

What Do You Want to Do?
Is it endodontics? Implants? Airway analysis? Orthodontics? The following table can help you determine what to look for in an imaging solution.

Is Your Objective ROI?
If you are considering a shift to in-house imaging, ask yourself how many times per month you refer patients out for a scan. If your average is four or more, it may make sense to invest in a cone beam computed tomography (CBCT) imaging system. In about a year or less, your system could pay for itself.* Continue reading

The Top Five Reasons Why You Really Do Need CBCT

The decision to add a cone beam computed tomography (CBCT) system to your practice is a significant one—and one that can have far-reaching implications. It is a sizable investment, so the concern for obtaining a return on that investment is often top of mind. The ability to accurately evaluate anatomy in 3D requires training, which is another point to consider. Logistics, such as how the system will physically fit into your office space or the impact it will have on your workflow, are additional factors that you should carefully examine.

There are definitely many considerations to take into account when making a decision like this. But for many practitioners, the choice was an easy one, because the advantages of introducing CBCT to their practice were—and still are—very compelling. Here are the main reasons why.

  1. Improved diagnostic capabilities
    The impact that CBCT has on your ability to diagnose should not be understated. In fact, some practitioners believe they can’t practice without it. CBCT imaging provides a level of anatomical detail that enables practitioners to detect clinical situations like infections, lesions and hidden anatomy. The information that CBCT reveals (when superimpositions are removed) sometimes results in practitioners changing their initial diagnoses, because what is not visible with 2D imaging is often blatantly obvious with 3D imaging.

    With improved diagnostic capabilities, you can discontinue the practice of referring patients out for scans, which helps speed return on investment (ROI). You may decide to perform more procedures—or more complicated ones—yourself because the information revealed by CBCT imaging gives you the clinical confidence to do so, which also positively impacts ROI.

  2. Patient education and case acceptance
    CBCT imaging facilitates patients’ understanding of your treatment plans. Because patients can more easily visualize the area of interest in 3D than 2D, they are better informed about the diagnosis and feel more included in the diagnostic process. As a result, they are more likely to accept the treatment proposal. In addition, better education allays patient concerns, resulting in a more positive patient experience.
  3. Marketing
    New technology is a great differentiator, and the addition of CBCT to your practice provides you with the perfect opportunity to promote your capabilities. When technology-savvy patients are looking for doctors who are on the cutting edge of their profession, they may choose you over the practitioner around the corner who hasn’t added CBCT to his/her practice. For specialists, this technology can attract more referrals, too.
  4. Referral relationship
    As a general practitioner, it’s important to me to refer my patients to specialists who have the most up-to-date technology and who can provide the level of care my patients have come to know and expect. On the other hand, as an implant specialist, I know that doctors refer their patients to my practice because I am able to clearly visualize implant treatment and placement.

    In addition to increasing referrals, CBCT imaging enables you to more easily collaborate with referring doctors on your recommended treatment plans and final outcomes. Seeing is believing, and the ability to reference a CBCT image can greatly simplify what may otherwise seem like a very complex treatment plan. Referring doctors will likely feel more comfortable with your treatment choices and enjoy the ability to collaborate on treatment plan options through the virtual treatment plans in the 3D software.

  5. Workflow
    CBCT can enhance your workflow by keeping patients within the practice for imaging—eliminating the extra step of sending them out for a 3D scan. When patients go from initial appointment to 3D imaging to treatment planning—all in one appointment—the time savings is enormous.

    Not only that but, when chosen wisely, CBCT systems can streamline your workflow by working seamlessly with your imaging and practice management software. And, depending on the procedures performed in office, CBCT scans can also be merged with digital impressions from an intraoral scanner to improve implant planning, surgical guide fabrication and more.

If you’ve already incorporated CBCT into your practice, what are some additional benefits you have experienced as a result?

The Secret to Choosing the Right CBCT Unit [Video]

When it comes to cone beam computed tomography (CBCT) imaging systems, there’s a number of bells and whistles to choose from. In this video, Jordan Reiss, Carestream Dental’s North American Sales Director for 3D Imaging, provides his advice on how to choose the right unit to meet your practices needs.

Whether you’re currently in the market for a 3D unit, or you already have one, what do you consider to be the most important criteria for choosing a system?

Baby, You Can Drive My CBCT System

In the 1950s, America saw the beginning of “car culture,” and today there are roughly 210 million licensed drivers in the United States. Driving is almost second-nature. However, if you’re used to driving a Volvo and I give you the keys to a Mercedes, it may take a moment or two of adjustments before you’re ready to cruise down the highway. It’s not because you don’t know how to drive; it’s just a matter of learning a new system.

A cone beam computed tomography (CBCT) system is not unlike becoming comfortable with a different make and model of car. I’ve been operating my system for years now, and can comfortably “turn on a dime” or “shift gears.” However, when I invite a referring doctor to “go for a drive,” e.g., share the 3D imaging software for collaborative cases or email a screenshot of a scan, there may be a bit of a learning curve. But once the general practitioner learns to properly view the scans, it not only helps me build stronger relationships with them, but allows for me to gain greater future referrals.

resportion-incisorFirst, CBCT allows me to view a patient’s anatomy in stunning 3D detail, and can reveal much more than what a traditional panoramic X-ray could. I share these CBCT scans with the referring doctor and usually get one of two responses—“Yes, good, proceed with treatment,” or “Your system showed you all that?! Tell me more…” Of course, it’s perfectly acceptable for the referring doctor to trust my judgment and go with my proposed treatment. However, there’s something to be said about the GP who wants to gain a better understanding of the CBCT findings.  Also, greater communication, increases the chances that future treatment will have less hurdles.

So if that’s the case, I take the time to meet with the general practitioner in person to go over the scan in more detail. For example, a CBCT can elucidate a proposed implant site with a buccal-lingual cross cross-sections for both horizontal measurements and for visualizing the distance from the crestal bone to the nerve canal.  My 3D imaging software is also easy to share, which gives the GP a bit more freedom to play around in the scan and take the CBCT for a “test drive.” Continue reading

Human Evolution or a Technological Revolution?

In the 1960s, root canal morphology was looked at differently than today. The common thought was that molars generally had three canals. Today, we know that there are often four, sometimes five canals. Have humans genetically evolved in the past 50 years? No. But new technology, such as cone beam computed tomography (CBCT), reveals minute details of root morphology like never before.

Essentially, CBCT allows us to miss less of what we did in the past by giving us high-resolution, three-dimensional scans of patient anatomy. Focused fields of view mean endodontists can review highly detailed images with up to 75 μm resolution (0.075 mm slices). Plus, when the doctor is able to see the root of the problem, it means a more comprehensive, and therefore successful, treatment plan and often times less post-operative pain for the patient.

Technology has changed dramatically over the past decades to allow us to diagnosis and treat patients in a way never thought possible. My partner recently retired, and in over 50 years, he rarely ever saw a tooth with five canals; whereas, my CBCT system has revealed dozens of cases with five canals. It’s just an amazing example of how CBCT is changing the way endodontists practice. Who knows what revolutionary technology will reveal next?

Tips for Choosing the Best CBCT System for Your Practice

When choosing technology for your practice you want to ensure you’re not only getting the best price, but the best fit for your practice workflow. A cone beam computed tomography (CBCT) system can be a big investment so you’ll want to consider many factors when shopping for a new unit.

Size

Let’s start with the obvious: Does your practice have the space for a CBCT system? Even if you think you don’t, technology has come a long way. CBCT systems released in the past few years can now literally fit inside closets. I’ve seen “before and after” pictures of cluttered bookshelves tucked in a corner one day and a compact 3D imaging system the next. Look for small footprints if you’re buying a new system, or ask if your existing pan system has the ability to upgrade to 3D. Continue reading

Endodontists and 3D Imaging (Video from Real World Endo)

When it comes to obtaining high-resolution 3D images for diagnosis and treatment planning, endodontists have turned to cone beam computed tomography (CBCT). CBCT scans give doctors an incredibly detailed look at a patient’s anatomy that can be viewed from every angle. Not only that, but sophisticated software offers doctors added confidence when treatment planning. In this video, Jordan Reiss, Carestream Dental’s U.S. director of 3D imaging, sits down with Dr. Allen Ali Nasseh, president and CEO of Real World Endo, to share some of the latest updates included in CS 3D Imaging Software version 3.5.7. This software is free and opens any DICOM scan, no matter which unit was used to acquire it.

3D Imaging software allows doctors to plan treatment for all kinds of endodontic scenarios. Most important, the ability to view the axial, coronal and sagittal of a patient’s anatomy, gives them the confidence that they’re accounting for every angle of the issue. This overview was provided by Real World Endo, a independent endodontic education, innovation and consulting company composed of a community of clinical and academic endodontists.

Determining Bone Density Using CBCT

You’ve heard the phrase, “quality over quantity,” but when it comes to implant treatment, both are equally important. Luckily for implantologists, advancements in technology now let us view the bone in 3D, saving time and taking the guesswork out of implant surgery.

In the video below, I’m able to view a cross section of a CBCT scan with my CS 3D Imaging software and share my “mental checklist” for determining bone quantity. Viewing the cross section also reveals the basic density of bone, which helps me to determine bone quality. Plus, I go over a few useful comparisons that you can remember when considering bone quality.

Bone quantity and quality plays a crucial role from the very beginning of implant planning. CBCT scans not only objectively reveal bone dimensions, but also let me know the density and maturity of the bone before I even begin to drill.

How do you determine bone quantity and quality? Do you have a case where you’ve had to reevaluate your approach to placing an implant after discovering the dimensions and quality of the bone?

Too Big? Too Small? How to Place an Implant Just Right. (Video)

Do you know what a “Goldilocks” implant is? Even if you’ve never heard the term, you’re familiar with the concept—when placing an implant, we don’t want it to be too big or too small but just right. But how do we find that perfect fit? There’s a lot to take into consideration:

  • Bone volume
  • Mesial-distal space
  • Apical-coronal space
  • Occlusal space
  • Anatomic limitations

I use my CS 3D Imaging software to generate precise measurements from CBCT scans captured with my CS 9000 3D extraoral imaging system or CS 9300 but there are also some key numbers I keep in mind when planning the perfect implant…
