3D X-Ray (CBCT)
Cone Beam computed tomography.
What is CBCT?
Cone Beam computed tomography (CBCT) is a radiographic imaging method that allows accurate, three-dimensional (3D) imaging of hard tissue structures, such as teeth and bones.
Using a 3D dental scanner equips dental professionals with a comprehensive view, letting them see specific conditions in the region of interest to determine whether a treatment is necessary. Because details show up so clearly, patients can be more confident in a dentist’s decision. In addition, the use of dental imaging technology often creates a more comfortable and engaging dental visit for the patient.
Dental cone beam CT is useful for treatment planning and more complex cases that involve:
The size of the main X-ray beam produced using 3D CBCT scanners helps to contain the radiation to only the target area, which minimizes unnecessary exposure to radiation.
Reduced radiation exposure
3D scans emit significantly less radiation compared to 2D scans, plus it is better focused to reduce scattered radiation and improve image quality. This reduces risks associated with prolonged, repeated radiation exposure such as eye damage, malignant tumours, and other health risks.
With that one CBCT scan, the dentist will receive a lot more details than a conventional 2D X-ray. The image shows pathology, musculature, nerves, infections, and much more, allowing the dentist to properly treat sinus issues associated with the teeth, properly plan for extractions, implants, and root canals, and accomplish a lot more in diagnostics and treatment planning.
Dental practitioners also enjoy the ability to explain treatment plans while demonstrating the features in 3D, which is not possible with 2D images. With CBCT scans, the dentist can reorganize data and magnify/annotate the image as desired.
With the numerous benefits of 3D diagnostic images, CBCT scans will soon become the standard in dentistry diagnostics. However, perhaps one of the features pushing for its quick adoption is how easy it is to learn using 3D dental equipment. Any trained dental practitioner can learn and work with the equipment quite easily.
Reduced scan time
CBCT scans can acquire all scan images from all angles in a single rotation that takes about 10 seconds for a regional scan or 20-40 seconds for a complete or full mouth X-ray, which not only reduces time spent on the scan, but also eliminates the risk of image defects caused by the natural movement of the patient.
As indicated from the previous points, 3D imaging can capture problems that would otherwise go unnoticed with 2D scans, because 3D scans can differentiate between different types of tissue. With 3D CBCT imaging, the dental practitioner can properly visualize and identify the pathology, infections, joint dysfunctions, and abnormal sinus anatomy for accurate diagnosis and treatment planning.
Unlike traditional 2D scans where you need to bite down on a mould, CBCT scans your whole head without requiring you to do anything, which is particularly helpful for patients with gum or tooth sensitivity and special needs, as well as children.
Bone quality evaluation
With 3D imagery, dentists can be able to assess the quality of underlying bone tissue for treatment planning. This is particularly important for dental implant placement to ensure there’s sufficient bone before treatment begins. 3D images also help to determine the size and location of breaks and lesions
Compared to visiting an imaging centre for the sole purpose of getting a 3D medical CT scan, having a CBCT imaging device in-house eliminates the extra cost of going to a third party for diagnosis.
