CBCT (3D X-ray)
Precise 3D X-ray for comprehensive diagnostics
Cone-beam computed tomography (CBCT) is a state-of-the-art X-ray technology in diagnostic imaging that is playing an increasingly important role in dentistry. In contrast to conventional X-ray images or classic computer tomography (CT), a CBCT provides three-dimensional, high-resolution images with significantly less radiation exposure. It therefore enables precise assessment of teeth, jaw bones, nerve courses and soft tissue and has become an indispensable part of modern diagnostics.
What is a cone-beam computed tomography (CBCT)?
A CBCT is a special, three-dimensional X-ray procedure designed for imaging the head, jaw and facial area. While conventional X-ray images only provide two-dimensional views, a CBCT can generate precise spatial images. This means that even complex anatomical structures such as fine root canals, nerve courses or bony changes can be seen in detail.
CBCTs works in a similar way to CTs, but with a much smaller radiation cone (cone beam method) and therefore with a significantly reduced radiation dose. Imaging takes place in real time, takes just a few seconds and is processed directly in digital form - without the use of X-ray film.
Advantages of CBCT
High image quality: The spatial representation in 3D enables an exact analysis of the jaw and tooth structure. Even the smallest changes such as fine cracks, root tip inflammation or bone defects can be detected.
Reduced radiation exposure: Compared to conventional CT, the radiation dose is significantly lower - with higher resolution in a small imaging area.
Improved diagnostics: The precise localization of nerve courses, cysts or inflammatory processes allows precise, comprehensive planning of interventions and increases patient safety.
Time-saving examination: the scan itself only takes a few seconds. The 3D image is then immediately available to the dentist.
Minimally invasive treatment planning: Thanks to precise pre-planning, procedures such as implantations or wisdom tooth extractions can be carried out more gently, safely and efficiently.
Areas of application
Digital volume tomography is used in many areas of dentistry and oral and maxillofacial surgery:
Implantology: The exact determination of bone height, density and nerve course is essential for the safe placement of implants. Thanks to a CBCT, implants can be planned with millimeter precision.
Endodontics (root canal treatments): A CBCT enables the visualization of complex root canal systems and assists in the localization of hidden inflammations, root fractures or undetectable canals.
Surgery: A CBCT provides all the necessary anatomical information before surgical procedures such as the removal of displaced wisdom teeth, cysts or jaw operations.
Temporomandibular joint diagnostics: In the case of temporomandibular joint complaints or functional disorders, a CBCT can show bony changes and contribute to differentiated diagnostics.
Periodontology: The three-dimensional visualization of bone resorption enables a precise assessment of the severity of periodontitis.
Procedure of a CBCT examination
Preparation: The patient is correctly aligned to avoid motion blurring.
Image acquisition: The CBCT device rotates around the head in a few seconds and creates several individual images, which are then combined to form a 3D model.
Analysis of the data: The volume data generated is displayed directly on the screen and analyzed by the dentist or oral surgeon.
Discussion of the results: The practitioner explains the findings to the patient and discusses the next treatment steps together.
Conclusion
A CBCT has become an integral part of modern dentistry. It combines high diagnostic accuracy with low radiation exposure and allows particularly safe and gentle planning of dental and surgical procedures. Patients benefit from better information, shorter treatment times and an overall higher level of treatment safety.
If you are about to undergo a major dental procedure, it is worth talking to your dentist about using a CBCT. The investment in modern diagnostics pays off in any case thanks to improved results and greater safety.
