No CBCT on site → do not book surgery day
Cone-beam CT shows height, width, nerves, and sinuses. A flat panoramic alone is not enough for implant planning. This page covers what to ask in the consult, how a CBCT differs from a panoramic X-ray, how to think about the extra radiation, and what to get on paper after the scan.
Ask in consult
- Is CBCT on site today, not "we send you elsewhere next week"?
- Can I see the scan with you on screen?
- Graft, angled implants, or wait: which, and why for this jaw?
Do not treat a scanner brand on a brochure as a guarantee that the machine is in the room today.
If bone is thin, that is a clinical path, not a blog yes/no. This aligns with questions before the chair and the All-on-4 checklist. Our page on zygomatic implants when bone is limited lists what to ask.
Panoramic vs CBCT: flat picture vs 3D volume
A panoramic X-ray is a single wide, flat image of both jaws. It is a good overview: teeth, obvious bone loss, old fillings, existing implants. But it squeezes a curved, three-dimensional jaw into two dimensions, so depth and width are hard to judge, and some areas can look stretched or overlapped.
A CBCT (cone-beam computed tomography) scan rotates around your head and builds a three-dimensional volume. The dentist can scroll through slices and look at the jaw from the front, the side, and from above. The FDA describes dental CBCT as providing 3D information rather than the 2D information of a conventional X-ray, which may help with diagnosis and treatment planning, and lists dental implant planning among its uses (FDA: Dental Cone-beam Computed Tomography).
| Panoramic | CBCT | |
|---|---|---|
| Image | One flat 2D picture | 3D volume you can slice |
| Good for | Overview of teeth and jaws | Planning a specific implant site |
| Bone width | Hard to judge | Visible in cross-section |
| Nerve canal and sinus | Approximate | Shown in 3D |
| Radiation | Lower | Higher than conventional dental X-rays |
They are not rivals. Many plans use both: a panoramic for the big picture, and a CBCT for the sites where implants go.
What a CBCT helps the dentist see before implants
On a CBCT the dentist can check things that decide whether, where, and how an implant can go:
- Bone height and width at each planned site, not just from one angle.
- The nerve canal in the lower jaw, which an implant must stay clear of.
- The sinus above the upper back teeth, and whether a sinus lift or angled implants may come up.
- Bone quality and shape, plus any surprises like old root tips or infections.
That is why the scan should come before a surgery date, not after. What the scan shows is the dentist's call. A blog cannot tell you "if your bone is X, you need Y."
Radiation in plain terms
CBCT uses X-rays, so it should be used when it is needed, not as a routine extra. According to the FDA, dental CBCT exams generally deliver lower radiation doses than other CT exams but typically more than conventional dental X-rays. The FDA says dental X-rays, including CBCT, should be done only when necessary, and that the clinical benefit of a medically appropriate exam outweighs the small radiation risk, while efforts should still be made to keep that risk low (FDA).
The FDA also suggests patients:
- Talk with the provider about the benefits and risks before the scan.
- Ask if the exam is necessary, and whether an equally useful option with less or no radiation exists.
- Keep a record of their own imaging history.
So it is reasonable to ask, "Why do you need this scan, and which area will it cover?" A good clinic will answer in plain words. We do not quote dose numbers here, and we do not call any scan "zero radiation."
Already have a scan from home?
Bring it. A recent CBCT from a US office, exported as a full volume (not a screenshot), may help the consult. See bring X-rays and records.
It may still not be enough. The surgeon may need a newer scan, a different area, or a scan in their own software for planning. That is a clinical decision after review. Ask what their cutoff is, and ask before travel day, so a new scan does not surprise you.
CBCT at Olive
Olive Dental Solutions has 3D CBCT imaging in the clinic. Ask to see your scan on screen during the consult, and ask the dentist to point out the bone, nerve, and sinus areas they are planning around. For location and booking details, read more about Olive Dental Solutions.
We will not claim Olive never re-scans, and we do not list equipment specs here. A scanner on a brochure is not the point. Your own scan, reviewed with you, is.
What to get on paper after the scan
After the CBCT, the written plan should reflect what the scan showed:
- Number and position of implants planned.
- Grafting or sinus lift: needed, maybe, or not needed, and why.
- Implant brand and line, named (brand on the paper).
- Staging: how many visits, and what happens at each (All-on-4: how many visits?).
- A copy of your scan, or how to request one, for your records at home.
Then compare it against the written plan checklist.
