Cone-beam computed tomography (CBCT), also called dental CT scanning, is an X-ray imaging method that uses a cone-shaped, rotating X-ray beam to produce X-ray images. CBCT scan is mostly utilized by the dentists and ENTs to visualize bone structure and differentiate teeth, maxillofacial region, eyes, ears, nose, and throat.
What Are the Uses of a CBCT Scan?
A CBCT Scan Machine is based on a rotation cone beam x-ray system to generate CBCT Scan images of the head and neck area representing maxilla, mandible, teeth, supporting bone, ear, nose, maxillary sinus, and other structures in its image. These images may be combined and adjusted to generate a 3D image too. The images assist your physician to assess the structures and diagnose for some conditions-
For Pathology Detection- CBCT is utilized to visualize and examine lesions (pathologies) in various structures of the head and neck area like the maxilla, mandible, jaw, teeth, gum etc. any pathology can be accurately positioned with the aid of the scan
For Orthodontic Planning Treatment- a CBCT may be an useful tool in facilitating orthodontic treatment planning. Orthodontic treatment can consist of braces, aligners,etc. Orthodontic treatment encompass different stages to make a comprehensive treatment plan that may encompass-
Cephalometric Analysis
Reconstruction surgery planning like BSSO surgery (bilateral sagittal split osteotomy), Lefort-1 osteotomy etc.
Impacted tooth visualization and extraction
Model analysis etc.
Sinus Condition Detection- Sinusitis, mucositis, nasal polyps etc are a few sinus-related pathologies that can be observed and assessed with the aid of a CBCT scan.
Detection of Temporomandibular joint disorders (TMJ)- The CBCT scan images are able to identify the cause and origin of any pathology involving the TMJ region. CBCT is also able to identify the TMJ dislocation or the TMJ subluxation. Any dislocation should be reduced as soon as possible by a trained dentist and specialist.
Detecting Other Sinuses- Other sinuses like nasal cavity, frontal sinus, paranasal sinuses are also scanned in the CBCT.
Dental Implant Planning- A CBCT is employed for placing implants to assess the amount of alveolar bone available and the adjacent structures. The examination may assist your physician to assess whether you require bone graft placement or other small surgeries for the success of implant placement.
Tumours and cysts analysis- A CBCT can reveal a tumour or any cysts which are appearing around the tooth or other head and neck area.
How is CBCT Scan Done?
A cone beam computed tomography is a method that gives a highly resolved image of teeth, jaw, and its associated structures with a cone beam x-ray machine. The process of conducting a CBCT scan is-
Before scanning – You shall be requested to take off any jewelry carrying your eyeglasses, earrings, noserings,any denture etc.belonging before going in for the scan.
You will be provided with a shield for shielding other areas of the body from unnecessary exposure. You may be provided earplugs or a headset to prevent noise as the machine emits clicking sounds while it’s in operation. The machine is switched on and the parameters of the projection are adjusted as per your age, height, field of interest, purpose of scan etc.
During scanning-
You sit in the CBCT machine
You have to sit calm while your face lays on a small ledge in front
There is a mouth holder where you will be asked to bite softly to hold your head firmly in place during scanning
The quality of the image relies a lot on your stability
The machine moves around you to take pictures as it sends low-dose radiation into you.
The machine takes approximately 2-3 minutes to do one scan.
After the scan-
Once the scan is finished, the raw image are then gathered by the CBCT machine’s detector
There raw data are interpreted to form a precise 3D picture of the teeth,jaw, and surrounding tissues by the computers
The report is synchronized and forwarded to your physician for additional assessment and treatment planning.
Are OPG Scan And CBCT Scan Same?
A CBCT sectional view scan And OPG scan are not the same in various ways;
One of the most important differences is how they provide images. CBCT scan images are three-dimensional and the OPG X Ray images are two-dimensional (2D). CBCT scan is more expensive than the OPG cost. The CBCT scan has advanced technology as well. The receivers for a CBCT scan do a better job producing three dimensional images than an OPG two-dimensional image.
The CBCT scan machine has built in its quality to create two-dimensional images as the OPG does, in addition to creating three-dimensional images. An OPG compares to the CBCT scan merely as a primary dental diagnostic tool, whereas the CBCT scan has an enhanced view and is used for further diagnostic and evaluation of pathology and conditions that are more difficult to see in traditional 2-D imaging.

Frequently Asked Questions
Q. What are the risks of a CBCT scan?
The CBCT process is done under guidelines of safety. It might still have some risks but cancer could be one of them but the chances of getting cancer from radiation are minimal. The children are more prone to radiation. For children the settings on the scanner are kept low exposure.
Q. Who will inform me about the results?
Your doctor or dentist who has requested CBCT scan examines the scan images and makes a diagnosis with the treatment plan. Then he will present you with the findings.
Q. Is a CBCT scan painful?
A CBCT scan is not painful and is an instant imaging method. You can resume your routine everyday activities as soon as you exit the centre.
Q. What is the cost of a CBCT scan?
A CBCT scan may vary between 1000-3000 based on the region where you are, the availability of CBCT scan machines, and the region of which the scan has to be done.
Q. How much time will a CBCT scan take?
It takes a single CBCT scan around 1-2 minutes. You may possibly require another scan based on the requirement and cause of your test.
