What is CBCT and when do we need it?

CBCT, short for Cone Beam Computed Tomography, is a medical imaging technique.

It uses X-rays to create three-dimensional images of the examined anatomical structure.


Its "conical" type is a specially developed kind of CT scan that was created to image tissues within our oral cavity and surrounding bone structures.

It allows for high-resolution imaging and three-dimensional reconstruction of parts of our body.



The scope of CBCT application in dentistry has been developing with high intensity – due to the numerous advantages of this method.

Currently used in e.g. orthodontics✨, maxillofacial surgery✨, endodontics✨, dental surgery✨, it allows doctors to precisely assess the status quo of Patients’ tissues, to plan treatment, perform surgery and monitor the progress of a chosen therapy.


Cone-beam tomography also offers a lower radiation dose (compared to traditional computed tomography), which contributes to an even greater safety.




But practically, when can cone-beam tomography be at its most useful? Let's look at a few examples:


✅ when planning implant placement.


CBCT allows for a thorough assessment of bone structures, their density and the presence of any anatomical obstacles before performing the procedure of dental implantation. The doctor will be able to precisely determine the suitable localisation and angle of insertion of the implant. As a consequence, the method contributes to increasing the durability and effectiveness of the treatment’s results.


✅ in the diagnosis of diseases of the teeth and other tissues of the oral cavity.


Cone beam tomography provides detailed imaging of teeth, their roots, periapical tissues, maxillary sinuses and anatomical structures around the mouth. It can help to diagnose problems such as odontogenic cysts, impacted teeth, tumours, cancers or some inflammations.


✅ when planning orthodontic treatment.


CBCT is useful for assessing bone structure and analysing complex cases. It provides the orthodontist with abundant information, showing, among others, the position of  teeth and the surrounding bone structure. This helps to construct and offer a more personalized orthodontic treatment plan.


✅ in the analysis of temporomandibular joint dysfunctions.


Constant pain when biting, persistent and annoying cracking sounds when opening your mouth? CBCT allows for the assessment of the TMJ and the diagnosis of abnormalities of these structures. Assessing the position of the articular disc, occlusal context and the current state of the bones are very important when it comes to the treatment of Patients with TMJ problems.


✅ in the diagnosis of some cancers, tumours and other pathologies.


Cone-beam tomography helps doctors to diagnose such above-mentioned conditions with greater accuracy, to plan treatment and procedures with high precision, and, last but not least, to monitor the progress of a treatment.
