What is a CT of the mandible, and how does it work?
A CT of the mandible is a three-dimensional X-ray scan of the lower jaw. The scanner rotates around your head, taking many images from different angles, and software builds them into a 3D model that can be viewed in slices from the front, side and top. Unlike a flat dental X-ray, it shows the exact height and width of the jawbone, the position of the nerve canal that runs through it, the roots of the teeth, the joint at the back of the jaw and any cysts, lesions or fractures. The scan itself takes between 10 and 40 seconds, and the whole appointment is usually 15 to 30 minutes. In dentistry it is most often done with cone beam CT (CBCT).
This guide explains when a mandible scan is needed, how it differs from other imaging, how safe it is, what it costs in Turkey against the UK, US and Germany and what to ask before you go. For the wider range of options see our dental treatments in Turkey.
When does a dentist or surgeon order a CT of the lower jaw?
A scan is requested when a normal X-ray cannot answer a question about depth, position or bone. The common reasons are:
- Dental implants: to measure the bone and mark where the inferior alveolar nerve runs, so an implant can be placed with a safe margin; see our guide to dental implants.
- Impacted or deeply placed wisdom teeth: to see how close the roots are to the nerve before removal.
- Cysts, tumours and infections: to show how far a lesion extends and whether it has damaged bone.
- Jaw fractures and injuries: to see the break lines and plan repair.
- Corrective jaw surgery: to plan bone cuts and movements; see orthognathic surgery.
- Jaw joint pain: to look at the temporomandibular joint when symptoms persist.
It is not a routine check-up tool. If a standard X-ray answers the question, a CT is not needed, and a dentist should be able to say what decision the scan will change.
Is CBCT the same as a hospital CT scan?
No, although both use X-rays to build 3D images. Dental CBCT uses a cone-shaped beam and a single rotation, is performed sitting or standing, and gives very good detail of bone and teeth. A medical (multislice) CT in a hospital radiology department uses a fan-shaped beam, shows soft tissue in more detail and can be done with contrast dye; it is preferred for tumours, infections that spread into the neck or major trauma. For most jaw questions linked to teeth and implants, CBCT is the usual choice. For a simpler overview see panoramic x ray, which is a flat image of both jaws.
| Scan | Suits | Typical limits |
|---|---|---|
| Panoramic X-ray | A first overview of teeth, jaws and sinuses | Flat image; cannot show depth or nerve position reliably |
| Cone beam CT (CBCT) | Implants, wisdom teeth, small lesions, jaw joint | Poor at soft tissue detail; image can blur with movement or metal |
| Medical CT | Tumours, spreading infection, major fractures | Higher radiation; usually costs more and needs a hospital |
What does the CT of the mandible show, and what does it not?
The scan reveals the shape and density of the jawbone, the position and thickness of the nerve canal, tooth roots, impacted teeth, hidden infections at root tips, cysts and some fractures. Planning software can place a virtual implant in the model and show the distance to the nerve. What it cannot do is show everything: soft tissues such as gum, muscle and the disc of the jaw joint are poorly seen, and a CT cannot make a diagnosis on its own. A radiologist or an oral surgeon reads the images together with your symptoms and examination. If the dentist wants a closer look at a particular area, the related cone beam CT scan guide explains the focused option.
Is a mandible CT safe? Radiation explained
Any CT uses ionising radiation, so it should only be done when the benefit is clear. A small-field dental CBCT generally delivers a lower dose than a hospital multislice CT of the head, though the dose varies with the machine, the area scanned and the settings; a flat panoramic X-ray usually gives less again. Professional bodies such as the American Dental Association and national radiation protection agencies advise using the smallest field and the lowest setting that answers the clinical question. Tell the staff if you are or might be pregnant, because scans are normally postponed unless essential. A lead apron or thyroid collar may be offered. Children are more sensitive to radiation, so a scan is only done when there is a firm reason.
CT of the mandible cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges for one scan and a written report, not hospital quotes. They depend on the type of scanner, the field of view and whether a radiologist report and digital files are included.
| Country | Approximate cost range |
|---|---|
| Turkey | €40 – €180 |
| United Kingdom | €100 – €350 |
| United States | €200 – €600 |
| Germany | €100 – €350 |
What changes the price: whether the scan is dental CBCT or a hospital medical CT, the size of the area, whether contrast is used, a written radiologist report and whether the images are given to you on disc or by secure link. In a treatment plan the scan is often included in the implant or surgery package, so ask whether it is billed separately.
How should I prepare, and what happens during the scan?
Preparation is minimal. Remove earrings, glasses, hearing aids, removable dentures and any metal from the head and neck, as metal causes streaks on the images. You stand or sit with your chin on a support, bite on a small guide to keep the jaw still and remain motionless for the scan. The machine moves around your head without touching you. Medical CT may need you to lie in the scanner, and if contrast dye is used you may be asked to fast for a few hours and to mention kidney problems or allergies. You can leave straight away, and there is no recovery period.
Your trip to Turkey and what to bring
A scan can be done in a single day, and often on the first day of your visit so that the dentist or surgeon can plan treatment with the images in front of them. If it is the only service you need, one night is enough, and if it is part of an implant or jaw surgery plan, the stay is set by that treatment. Bring any earlier X-rays, scans or reports and a list of medicines. Ask for the images in DICOM format on a disc or secure link, because your own dentist or surgeon at home may want to review them. There is no aftercare, but you should receive a written report with a clear statement of what the radiologist saw.
What do results look like, and what can go wrong?
You receive a set of images and, usually, a report. There is no before and after in the aesthetic sense: the value of the scan is in what it changes about your plan. For example, it may show you have enough bone for an implant, or that a graft or a sinus lift is needed first, or that the nerve lies too close to risk a wisdom tooth extraction without precautions. Problems are rare and mostly practical: movement blur or metal artefacts can make a scan hard to read and force a repeat, an incidental finding such as a cyst or a sinus change may need further checks, and each scan adds a small dose of radiation. Scan once for the plan rather than several times for convenience.
How to choose a clinic for jaw imaging, and red flags
Choose a licensed dental or radiology centre where the operator is trained, the machine is serviced and the images are reported by a dental radiologist or maxillofacial specialist. Check that the clinic explains the dose, uses the smallest useful field of view and gives you the digital files. Red flags include a scan ordered with no examination, repeated scans without reason, no written report, refusal to give you the images and a price quoted with no detail of what it covers. Read how our service works and request a plan through our free quote page, where the clinic confirms whether the scan is separate from treatment.
Questions to ask the clinic:
- Which scan do you recommend, CBCT or a hospital CT, and why?
- What decision will the images help you make?
- What is the approximate radiation dose, and can a smaller field be used?
- Will a specialist write a report, and will I receive the files in DICOM format?
- Is the scan included in the price of treatment, or billed separately?
- What happens if the scan reveals something unexpected?

Frequently asked questions
It is a three-dimensional X-ray scan of the lower jaw that shows bone, tooth roots, the nerve canal and any lesions. In dentistry it is usually a cone beam CT that takes less than a minute.
Common reasons are planning dental implants, assessing impacted wisdom teeth, finding cysts or infections, checking fractures, planning jaw surgery or investigating jaw joint problems that a flat X-ray cannot explain.
Approximate ranges are €40 to €180 for a scan in Turkey, against about €100 to €350 in the UK. The price depends on the scanner type, the field of view and whether a written report is included.
It uses ionising radiation, so it is done only when needed. A small-field dental scan generally gives a lower dose than a hospital CT, and the smallest useful field and lowest setting should be used.
No. You stand or sit still for 10 to 40 seconds while the scanner rotates around your head. If a medical CT with contrast is used, an injection may cause brief discomfort.
A panoramic X-ray is a flat picture of both jaws, while CBCT gives a 3D model showing depth, nerve position and bone thickness, which is why it is used for implants and surgery planning.
The scan takes under a minute and the appointment 15 to 30 minutes. There is no recovery, and you can return to normal activity immediately after the scan.
Scans are normally postponed during pregnancy unless the benefit clearly outweighs the risk. Tell the staff if you are or might be pregnant, so the dentist can decide whether the scan can wait.
You should receive the images in DICOM format on a disc or secure link, and a written report from a radiologist or specialist. Ask for both before you leave so your own dentist can review them.
The scan itself takes one visit, so one night is enough if it is the only service. If it is part of implant or jaw surgery, the length of stay depends on the treatment plan.
