A Clearer 3D View When Your Care Calls for It
What Is Cone Beam Imaging?
Cone beam imaging, also called cone beam CT or CBCT, is a 3D X-ray of your teeth, jaws and the areas around them. During the scan, the machine’s arm circles your head and takes a series of images from different angles. Software combines them into one 3D picture we can turn, slice and measure on screen.
A regular dental X-ray is a flat picture. A 3D scan adds depth, so we can see the height and width of your jawbone, where nerves and sinuses sit, and exactly where each tooth is, including teeth that haven’t come in. That’s detail a flat X-ray can’t show.
A cone beam scan uses less radiation than a medical CT scan. It uses more than a standard dental X-ray, like the small X-rays taken at checkups or a panoramic X-ray. That’s why we don’t take one routinely. We recommend a scan only when a 3D view will change or improve your treatment plan, and we’ll explain why first.
A 3D scan is often helpful for:
- Planning dental implants
- Impacted teeth and some extractions, such as wisdom teeth that sit close to a nerve
- Certain orthodontic cases, such as teeth that haven’t come in where they should
- Planning certain root canal cases, such as unusual root shapes or an infection that’s hard to see on a flat X-ray
- Checking the sinuses when a flat X-ray leaves questions
Benefits of Cone Beam Imaging
See What a Flat X-Ray Can’t
A 3D view shows bone, nerves, sinuses and tooth positions from every angle. That can reveal issues that may not show up on a regular X-ray.
More Precise Planning
Measurements from your scan help us plan complex care, like where an implant should go, in more detail. We’ll walk you through the images so you can see what we see.
Used Only When It Helps
A cone beam scan uses more radiation than a regular dental X-ray. So we recommend one only when the 3D detail will make a real difference in your care, and we scan the smallest area that answers the question.
What to Expect
The scan is taken right here in our office, and there’s no special prep. Before your scan, we’ll ask you to take off anything metal around your head, like earrings, glasses, hairpins or hearing aids, along with any removable dental work.
You can sit or stand for the scan. You’ll stay still for a short time while the machine’s arm moves around your head. Depending on what we need to see, the scan may cover a small area or your whole jaw. We use the smallest area that answers the question. Once it’s done, you can get right back to your day.
Please tell us if you’re pregnant or might be, so we can plan around it together.
For children and teens, we take extra care. Younger patients are more sensitive to radiation, so we recommend a scan for them only when a lower-dose X-ray can’t give us the answer we need.
Why Choose St. Johns Smile Co.?
At St. Johns Smile Co., we use modern tools when they help you understand your care and help us plan it well. A cone beam scan is one of those tools, and we use it thoughtfully. Dr. Awad may use a scan to plan implants and other complex dental care, and Dr. Labib may use one for certain orthodontic cases. When we take a scan, we sit down with you, show you the images and explain what they mean for your plan.
We’re a family-owned practice, and we want you to feel comfortable asking questions. Ask why we’re recommending a scan, what we’re looking for, or whether a lower-dose X-ray would do the job. We’ll give you a straight answer. We’re proud to care for families in Nocatee, Ponte Vedra and nearby St. Johns communities.
