CBCT scan is a great tool that we started using in dentistry since late 90s.
Unlike the 2D xray images, a 3D CT scan provides 3 dimensional view of the field of interest. Allowing for getting information that used to be very hard to reveal without surgically being in that area.
In Dentistry, this technology is considered an evolution to the way we can plan for different procedures, the ability to view the teeth and the bone of the jaw in 3D view can reveal information that a lot of the times goes missing with conventional 2D radiography leading to incomplete or defective treatment.
The 3D CBCT in dentistry is mainly used in the following categories:
Diagnosing and evaluation the height as well as the width of the bone of the jaw to plan for dental implants placements. Also with CT scans we can detect and locate the position of different vital structures that have to be preserved and handled very carefully during the procedure such structures are: Nerves, Maxillary sinus.
Often a big cause of failures for root canals is a missed canal; that is a canal within the root that was not seen during the normal procedure.
With CBCT, we can detect and visualize all the canals before doing the procedure and thus reducing the time of the procedure and minimizing errors that can happen due to missed canal or incomplete root canal treatment.
By nature, wisdom teeth are located close to very important vital structures that if traumatized can lead to some serious complications, Of these very important vital structures are the:
‘’Inferior Alveolar Nerve’’ in lower jaws which if traumatized then there is a big possibility that an alteration or even loss of sensation can result. ‘’Maxillary sinus’’ in upper jaws, careful planning is often very important to prevent traumatic communication between site of extraction and maxillary sinus.
-For diagnosing of unclear problems:
There is a lot of times where it is very difficult and sometimes impossible to diagnose and point clearly to the source of problem, as regular X-rays can only tell us some information being only in 2D. a lot of the times an infection or a problem gets covered by a root or another structure hiding the source of the problem, this is where 3D CBCT technology becomes a great tool as it shows 3 dimensional view of the tooth, just like holding the tooth in your hand and rotating it to view from all different angles.
