A CBCT scan is a 3D dental X-ray that shows the bone and nearby structures such as the nerve canal and the sinus. 3D planning links it to the planned teeth to simulate implant positions. Dr. Türker Clinic in Istanbul plans from 3D CBCT imaging and a clinical examination, and sets the final plan only after examining you.
A CBCT scan, often called a “3D dental scan,” shows the jawbone and the structures next to it in three dimensions. 3D planning links that scan to the planned teeth, a surgical guide can help carry the plan into the mouth, and photogrammetry records the position of several implants. These tools add information and can refine certain steps, but they remove neither surgical risk nor uncertainty about the result. Their value depends on the indication, the quality of the data and clinical checks.
If you are considering implant treatment in Turkey, 3D dental imaging is one of the first things worth understanding. This guide explains what each digital tool does, what it cannot do, and which questions to put to a clinic about how your plan is built.
Four tools, four jobs
Each tool answers a different question, and none replaces a clinical examination. The table sets them side by side.
| Tool | Main information | Possible use | Key limit |
|---|---|---|---|
| CBCT | Bone volume and anatomical structures | Diagnosis and choice of sites | X-rays, artifacts, soft tissues poorly described |
| Intraoral scanner (optical impression) | Surface of the teeth and gum tissue | Digital model and bite | Mobile areas, blood or saliva; toothless arches can be hard to scan |
| 3D planning | Anatomy and prosthesis overlaid | Simulating position, diameter and angulation | The simulation depends on the data and can differ from reality |
| Photogrammetry | Spatial relationships between implants | Digital impression of an implant-supported arch | Does not replace every prosthetic record |
The first two tools supply data, planning links the data together, and photogrammetry comes in later, when the prosthesis is designed. The surgical guide, described below, carries the plan into the mouth.
The CBCT scan: what it shows and what it does not
CBCT (cone beam computed tomography) is the imaging technique commonly called a “3D dental scan.” For many implant projects it provides three-dimensional information on the volume of bone and on how close structures such as the mandibular canal (the nerve canal of the lower jaw) or the sinus are.
When bone volume is limited, what comes next depends on the technique being considered. See the guides on dental implants without a bone graft, the sinus lift and the choice between subperiosteal and zygomatic implants.
Is it routine?
Not automatically. Imaging has to be justified and suited to the clinical question. Because a CBCT uses X-rays, the area scanned and the settings should be matched as closely as possible to the purpose, in line with radiation-protection principles.
What it does not detect
A CBCT does not detect everything. Metal restorations can create artifacts; some anatomical boundaries remain hard to read; and the state of the soft tissues and the biological activity of a site cannot be judged from an image alone. It also does not record, on its own, how the teeth meet: the bite (occlusion) comes from an optical impression or a model, together with the clinical examination.
A written report and an oral examination therefore remain necessary. An old or incomplete image may need to be retaken once that is justified.
From scan to plan: how 3D planning is built
The workflow generally combines the CBCT volume, an optical impression or a model, the bite, photographs and the planned teeth. The clinician looks for a position that works at once with the bone, the anatomical structures, the way the future prosthesis will emerge from the gum, ease of cleaning and the distribution of forces.
- Check the quality of the data and that the files match one another.
- Define the prosthetic plan before the implant position.
- Simulate the implants and components.
- Choose between free-hand surgery, partial guidance and a full guide.
- Prepare a fallback strategy in case the real anatomy differs.
- Check the position and the prosthesis in the mouth.
The software helps with decisions; it does not make them. The plan remains provisional: it is confirmed or corrected during the examination and again during surgery.
Dr. Türker Clinic plans implants from 3D CBCT imaging and a clinical examination, and sets the plan only after that examination, never from a description alone.
Surgical guides and photogrammetry
Guided surgery: precision is not the same as zero deviation
A surgical guide is manufactured from the plan and rests on the teeth, the gum tissue or the bone. Deviations can come from the imaging, from merging the files, from manufacturing, from play in the instruments, from how the guide seats, or from movement during surgery. They justify safety margins and the surgeon’s ability to change the plan.
Guided surgery is not necessarily “incision-free,” nor less painful, nor quicker in every case. An opening may be needed to see the bone, manage the tissues, extract a tooth, place a graft or deal with something unexpected.
Photogrammetry: what is it for in a full arch?
Implant photogrammetry measures the relative position of reference bodies attached to several implants. It can help record a full arch when the accuracy of the framework’s fit is critical. But the tissues, the bite, the vertical dimension, the aesthetics and speech still have to be recorded by other means.
A precise capture does not erase an unfavorable implant position, a poorly seated component or an inadequate prosthetic plan. Your clinician must verify passive fit and accuracy of fit in the mouth.
A fast digital capture does not shorten the biology of healing either. Immediate loading still depends on stability and on the whole case, not on the mere presence of a piece of equipment, and a prosthesis placed immediately is often temporary. For the full course of a full-arch treatment, see the full mouth rehabilitation timeline.
Limits, alternatives and when to postpone
More technology does not automatically improve the result: a tool is worth something only if it answers a clinical need, is used correctly and fits into a coherent plan. These technologies may be limited, or the phase concerned postponed, in the following situations
- patient movement or CBCT data degraded by artifacts;
- mouth opening too limited for the guide and the instruments;
- unstable support on a toothless arch;
- infection, tissue that needs managing, or anatomy that differs from the simulation;
- incomplete files or an uncertain overlay;
- a change to the plan after an extraction;
- inability to confirm that the components are seated.
The fallback can be conventional surgery, a new acquisition, a physical impression, a different temporary prosthesis, or postponing the definitive phase.
Checklist: what to ask the clinic
- Who prescribes, interprets and archives the CBCT?
- How are the dose and the area scanned justified?
- Which data feed the prosthetic plan?
- Which type of guide is planned, and how is its support checked?
- Which deviations or events lead to abandoning the guide?
- How are the implant positions and the fit verified?
- Which files, X-rays and references will you be given?
These points complement the implant passport and make follow-up easier once you are back home. For a broader list, see the 30 questions to ask a dental clinic in Turkey.

Having your case assessed
Send your existing imaging (a panoramic X-ray, and a CBCT scan if you have one) and your goals to Dr. Türker Clinic, for example on WhatsApp at +90 531 818 02 87. The team can tell you whether the documents are usable and which acquisitions might be justified after an examination. A remote opinion stays conditional, and there is no rush at this stage. To compare two proposals, second opinion for dental implants explains which file to provide.
This page is an information guide: it does not make any diagnosis remotely and does not replace a clinical examination.
Frequently asked questions
Can I have a 3D dental scan in Istanbul before planning an implant?
A 3D scan is part of planning when your clinical question justifies it: Dr. Türker Clinic, in Nişantaşı (Şişli, Istanbul), plans implants from 3D CBCT imaging and a clinical examination. If you already have a recent one, send it: the team will tell you whether it is usable or whether a new scan is justified.
Is a CBCT scan enough to get a final implant plan remotely?
No. A CBCT describes the anatomy, but the clinical examination, your bite, the condition of the tissues, your medical history and sometimes new imaging can all change the plan. Dr. Türker Clinic sets the plan after examination; you can send existing imaging to find out whether it is usable.
Do a CBCT scan and an intraoral scan work together to plan an implant?
Often, yes. The CBCT supplies the bone volume and the optical impression supplies the surface of the teeth and gums. Overlaying them links the bone to the planned teeth, provided the files are complete and their match is checked before any implants are simulated.
What is “double planning” between a CBCT scan and the prosthesis?
The term can cover different protocols depending on the practitioner. The general principle is to choose the implant position by weighing both the bone (CBCT) and the prosthetic plan (tooth position, bite, how the prosthesis emerges from the gum), then to check that the data match before simulating. Ask the clinic what exactly it means by the term.
Does a CBCT scan record my bite?
Not on its own. A CBCT mainly describes bone and anatomical structures. Your bite, meaning how the teeth meet, is recorded with an optical impression or a model and completed by the clinical examination. Metal restorations can also create artifacts on the image.
What does a CBCT scan not show?
It describes soft tissues poorly, cannot show the biological activity of a site, and can be disturbed by artifacts, notably near metal restorations. Some anatomical boundaries remain hard to read. A written report and an oral examination are therefore still needed.
Does guided surgery remove the risk of touching a nerve?
No. A guide can help carry the plan into the mouth, but deviations exist: the imaging, the merging of files, manufacturing, how the guide seats and movement during surgery. Diagnosis, safety margins and the surgeon’s judgment remain essential, and guided surgery is not necessarily incision-free.
Does photogrammetry replace a dental impression?
Not entirely. It mainly records the relative position of the implants. The tissues, bite, vertical dimension, aesthetics and speech still have to be recorded by other means. It corrects neither an unfavorable implant position nor a poorly seated component.
This guide informs; it does not replace a consultation or an individual diagnosis. Every case needs a clinical examination and 3D imaging.
