Susie Soleimani Photography - Amazing Digital Dental Imaging in 3D Cone Beam - Orthodontic
Three Dimensional Scans - The Future in Orthodontic Imaging - Presented by Susie Soleimani an Amazing Photographer and Dental Management Consultant
We are an industry that focuses on three-dimensional planes of space. Yet our imaging, until now, has been capturing only two dimensions. My purpose today is to illustrate some of the advantages presented by 3 dimensional imaging technology.
Slide 2 - 2D Vs. 3D - There are 3 major limitations when viewing two dimensional radiographs.
1 – One is Distortion
2 - Limited view
3 - Lack of variety in images
Slide 3 – Let’s address the first (Distortion)
Quite often 2 dimensional imaging distorts the image when taking a 3 dimensional object and flatting it in order to show it in a 2 dimensional view such as a traditional panoramic radiograph.
This is a traditional Pan. It is of a 9 year old boy with transitional dentition. Here we see his permanent laterals rotated and coming into position, and his canines attempting to squeeze through in between the laterals and the first permanent premolars.
Slide 4 - This is a Panoramic view pulled from the same patient's Cone Beam CT scan. In this view, we see that the canines' actual location is in fact between the centrals and the laterals. This important detail was distorted in the traditional pan in such a way that it appeared the canines were behind the laterals where they should be. Not in between the centrals and the laterals.
Slide 5 - This is a three dimensional Volumetric image of the same patient. This is an image produced by a mathematical calculation of the dicom data.
Slide 6 – The second disadvantage of 2 dimensional imaging is Limited view - This is a Traditional Pan taken of a 12 year old boy. In this view, we can see his canines coming in on top of the apex of his laterals. Though this is a good image, it is limited to one view and does not tell us the exact location of those canines, in relationship to the laterals.

Slide 7 - This a Volumetric image of the patients full scan. It is rotated forward in order to better depict the relationship of the canines to the roots of the laterals. If I had the application here, I would be able to grab the image with my cursor and move it around in any way I wanted. Up, down, left, right, inside, & outside. Since the application is not here, I have taken still images of some of the many available views.

Slide 8 – This the anterior view,
Slide 9 – This one is from above, note the canines “here” (pointing at canines), And the laterals “here” (pointing at laterals)
Slide 10 - From Below, again, here are the canines, and the laterals
Slide 11 - From the Left, canines, laterals.
Slide 12 – And this view, is from above, after clipping the lower jaw to eliminate overlap. In this application, in addition to the ability to move the image around in any direction, you also have the ability to eliminate portions of the image in order to have a better view of what’s behind it, or in front of it.
Slide 13 - And finally, this a Cephalometric view pulled from the same scan.
Slide 14 – Next, we look at Variations – This is the really fun part. These are a few of the variations in the enhancement of color, contrast, and brightness available from the many 3D software applications out there. The ones I am about to show are from 3 different applications. These are just a sampling as there are many different variations to the images you can produce. This particular on we are looking at, is similar to a traditional Ceph. What we do here however, that you can’t do with a traditional Ceph, is clipping. Half of the image, being from the midline to the right (gesturing on my face), has been removed in order to eliminate overlap. In a traditional Ceph, you are looking at both sides of the arch overlapping on top of one another. So for example, if you have a radio opaque crown, you would not be able to see the tooth on the other half of the arch.
Slide 15 – This on is what is known as an MIP - Maximum Intensity Projection.
Slide 16 - Another Ceph but with more contrast,
Slide 17 – A Frontal Ceph,
Slide 18 – A Frontal MIP Ceph.
Slide 19 – A High contrast Frontal MIP Ceph.
And now for the fun ones. These are the ones I show the kids when they’re bored in the Consult or they’re upset because they need to get braces.
Slide 20 - This one is what I'd look like with my head on fire.
Slide 21 - This is me on St. Patrick's day,
Slide 22 - Me after chewing too much bubble gum,
Slide 23 - And finally, me as the Terminator. I once convinced a very upset boy that if he sits through the bonding, I’d email him this version so he can put on his Facebook page.
I hope you’ve enjoyed seeing some of the variety of imagery available. Obviously, every office can’t go out and but a Cone Beam CT. However, it is nice to see the technology advancing and if you’re interested in having these images available to you, you can always search around your area and find a surgeon, periodontist, or other facility that has the machine and would love to see your patients and do the scans for you. There are also plenty of Radiology groups that read the scans, look for pathology, pull the images and email you everything in a comprehensive report.
