Cone beam CT scan in Turkey: what it is and how it works
A cone beam CT scan (CBCT) is a dental and facial X-ray scan that produces a three-dimensional image of the teeth, jaws, sinuses and nerve canals. The machine rotates once around your head, usually in 10 to 40 seconds, sending a cone-shaped X-ray beam; a computer rebuilds the many images into a 3D volume that the dentist can rotate, slice and measure on screen. Unlike a flat X-ray, it shows depth, so the dentist can see how thick the bone is, where the nerve runs and whether a tooth root sits close to the sinus.
The scan is a diagnostic test, not a treatment, so there is nothing to recover from. It is the base of the digital plan for many implant cases and is often the first step in a dental trip. This guide explains what it shows, when it is worth having, what it costs in Turkey against the UK, US and Germany, how it compares with a panoramic X-ray and what to ask a clinic.

What does a cone beam CT scan show that an ordinary dental X-ray does not?
Flat X-rays squash the jaw into two dimensions, so structures lie on top of each other. A cone beam scan separates them. It shows the height and width of the jawbone in each planned implant site, the course of the lower-jaw nerve canal, the floor of the maxillary sinus, the shape and number of root canals, cracks or lesions at the root tip, the position of impacted wisdom teeth and canines, and the joint of the jaw. It also shows airway space and, in orthodontics, the position of teeth within the bone. Soft tissue such as gums, muscles and the disc of the jaw joint is not shown well; that needs MRI or an examination.
When do dentists ask for a cone beam CT scan?
The clearest use is before an implant: bone volume and nerve position decide the implant size and whether a graft is needed. Guidelines from dental radiology bodies support CBCT when a conventional X-ray does not answer the clinical question, rather than as a routine for every patient. Typical reasons include:
- Planning one or several implants, or a full-arch bridge (see dental implants).
- Assessing impacted or deeply placed wisdom teeth close to the nerve.
- Complex root canal problems, suspected root fractures or failed root treatment.
- Checking jaw cysts, bone lesions or sinus involvement from upper teeth.
- Planning orthodontic movement of impacted teeth, or jaw surgery.
For a simple check-up or a cavity, a CBCT is usually not needed.
Does a cone beam CT scan improve implant treatment?
The evidence is strongest for accuracy of planning: 3D measurements of bone and nerve position reduce the chance of choosing an implant that is too long or placed too close to a nerve or sinus. Reviews of imaging in implant dentistry show that CBCT changes the plan in a meaningful share of cases compared with a panoramic X-ray alone. Evidence that CBCT improves implant survival or patient outcomes is less direct, because outcome depends on the surgeon and the patient as much as on the scan. A scan also does not replace a clinical examination: the dentist still needs to look at gums, bite and oral hygiene.
Cone beam CT scan cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges for one dental scan, not hospital quotes. Some clinics include a CBCT in an implant plan or refund the scan if you go on to treatment.
| Country | Approximate cost per scan |
|---|---|
| Turkey | €40 – €150 |
| United Kingdom | €100 – €350 |
| United States | €150 – €500 |
| Germany | €90 – €300 |
What changes the price: the size of the field (one jaw, both jaws or the whole head), whether a radiologist writes a report, whether the scan is part of a treatment package and whether it is a stand-alone private scan or ordered by a specialist. A full report from a dental radiologist costs more than a scan read only by the treating dentist. Ask whether you receive the files on a disc or by download, which is essential if you want a second opinion at home.
Cone beam CT, panoramic X-ray or medical CT: which is used for what?
| Scan | Best suited to | Typical limits |
|---|---|---|
| Cone beam CT | 3D bone, nerve and root questions; implant planning | Poor for soft tissue; metal fillings cause streaks |
| Panoramic X-ray | Overview of all teeth and jaws, first screening | 2D only; no accurate bone thickness |
| Medical (multislice) CT | Large tumours, trauma, soft tissue and neck | Higher radiation dose; more costly; less detail for small dental areas |
Many clinics take a panoramic image first at a first visit and add a cone beam scan only when the question requires it. In an implant case a CBCT may also be merged with a scan of the teeth for guided surgery, described in our guide to immediate All-on-4.
What is the radiation dose, and is a cone beam scan safe?
Any X-ray uses ionising radiation, so the principle is to use it only when the answer will change the treatment. The dose from a dental CBCT depends strongly on the machine and the field of view: a small field of one jaw segment gives a dose closer to a few panoramic X-rays, while a large field of the whole head gives more, though in general still lower than a medical CT of the same region. Authorities such as the FDA, Public Health England (now UKHSA) and the American Dental Association publish guidance on dental imaging. It is generally advised to avoid unnecessary scans in children and pregnancy, and to ask the operator for a limited field and the lowest practical dose.
What happens during the appointment, and who is a good candidate?
You remove metal objects such as earrings, glasses, piercings and removable dentures. You stand or sit with your chin on a rest and bite on a small plastic block so the head stays still; a lead apron may be offered. The scanner rotates once while you stay still for the 10 to 40 seconds of the scan, and the images are ready in minutes. The whole visit takes about 15 minutes. You are a good candidate if a dentist needs 3D information for a defined question. You may not be suited if you are pregnant (unless the benefit clearly outweighs risk), cannot stay still, or have already had a recent scan that can be sent over; in that case ask the clinic to use it.
Recovery, timeline and how long to stay in Turkey
A cone beam scan needs no recovery: you return to normal activity at once, and there are no restrictions. If the scan is taken as part of a dental trip it fits into the first appointment, usually on arrival day, and a report or plan is ready the same or the next day. Many clinics also review a CBCT you took at home and give a preliminary plan before you travel, which can shorten the stay; a scan taken less than six months before treatment is normally accepted. The images should be sent in DICOM format, which is the standard type for 3D scans.
What does a cone beam CT scan result look like, and what does it not show?
The result is a set of slices and a 3D model. In an implant case, the dentist marks the nerve canal and measures the bone height at each tooth site; a small pin-point cross-section shows how wide the jaw is where an implant would sit. In a root canal case a tiny dark area at a root tip may show infection that a flat X-ray missed. The scan does not show cavities as clearly as a bitewing X-ray in all cases, does not show gum disease directly and can be blurred by metal fillings, implants or movement. A good report states what is normal as well as what is abnormal and mentions incidental findings, such as sinus disease, that need follow-up elsewhere.
How to choose a clinic for a cone beam CT scan and what to ask
Check that the scanner is in the clinic or a named imaging centre, that the operator is trained in dental radiography and that a dentist or radiologist reads the images. Red flags include a scan offered to everyone without a clinical question, no explanation of the dose, and no copy of the files for you.

Frequently asked questions
It is a dental X-ray scan that rotates once around the head and builds a 3D image of the teeth, jaws, sinuses and nerve canals. Dentists use it to plan implants and diagnose root or bone problems.
Approximate ranges are €40 to €150 per scan in Turkey, against about €100 to €350 in the UK. The price depends on the field size, whether a radiologist reports and whether it is part of a treatment package.
It uses ionising radiation, so it should only be taken when the result will affect treatment. The dose depends on the machine and field of view and is generally lower than a medical CT of the same region.
The scanner rotates for about 10 to 40 seconds, and the whole appointment takes around 15 minutes. Images are usually available within minutes.
No. It is a quick imaging test with no anaesthetic or incision, so you return to normal activity immediately.
A panoramic X-ray is a flat overview of all the teeth, while a cone beam CT gives a 3D view with accurate bone thickness and nerve position. CBCT is chosen when depth matters, as in implant planning.
Often yes. It shows bone height, width and nerve position, which decide the implant size and whether a graft is needed. A simple case may be planned from a panoramic image alone, at the dentist's discretion.
Usually yes if it is recent, covers the right area and is sent as DICOM files. The clinic will say whether it is enough or whether a new scan is needed.
Not reliably. It is suited to bone, roots and nerves. Cavities are better seen on bitewing X-rays and gum disease needs a clinical examination.
No. The scan takes minutes and is normally part of a first dental visit. Many clinics will review a scan you already have and give a plan before you travel.
