Cone Beam Computed Tomography (CBCT), also known as a 3-D X-ray, is performed when regular dental or facial X-rays are inadequate. This uses a special technology that produces high-quality, 3-D images of the dental structure, the soft tissues that make up the gums, the nerve paths, and the bone underlying the teeth with precision.
The images produced are then used to evaluate gum diseases, the bone framework of the face, nasal cavity, and sinuses, allowing more accurate treatment.
Uses of Cone Beam/3D X-Ray
Cone-beam CTs are used to detect complex oral problems, some of which include:
- Surgical planning for impacted teeth, i.e., the teeth that have not emerged due to lack of room or have grown in the wrong direction
- Precisely placing dental implants
- Measuring and treating jaw tumors
- Determining teeth orientation and structure in an individual
- Helps in reconstructive surgery
- Determining whether or not a root canal is the most optimal choice for you
- Diagnosing TMJ and fractures
How Does a Cone Beam CT Scan Work?
The cone beam uses a rotating platform attached to an X-ray source and a detector. Due to the unique cone structure of the apparatus, the CBCT produces hundreds of planar projection images during a single rotation and allows to envisage the entire field of vision. This is not possible in a traditional scanner. The fan-shaped beam stakes the individual image slices to create a complete 3-D representation.
How Are You Prepared for a Cone Beam CT?
Cone-beam CTs are a very common and safe imaging technique. It is quick and painless and doesn't need extra preparations. Before the X-ray, everything that obstructs the process like metal objects, jewelry, eyeglasses, hair accessories, or hearing aids, should be removed. Removable dental gadgets should be taken off before the procedure as well. The examination cannot be performed if you are pregnant.
Patients are told to lie down or sit upright in a chair during the procedure. The C-arm of the apparatus rotates around the head and captures multiple images, which are then digitally combined to form the 3-D image.
Advantages of a Cone Beam CT
- Cone beam CT has lower radiation exposure than conventional CT.
- It captures a wide variety of images from almost every angle that helps in an easier and more accurate assessment of the disease.
- It is less time-consuming and has no immediate side effects.
