Dental Cone Beam CT (CBCT)
Dental Cone Beam CT (CBCT)
What is a CBCT?
A dental CBCT (cone beam computed tomography) is a specialized type of X-ray machine that produces a 3D image of the teeth, jaws, and surrounding structures. The CBCT scanner rotates around the patient’s head, taking multiple X-ray images from different angles. These images are then reconstructed into a 3D image that can be viewed on a computer screen.
What is a CBCT for?
Dental CBCT scans are used to provide more detailed information than traditional dental X-rays, particularly for complex dental procedures such as dental implant placement, orthodontic treatment planning, complex endodontic treatment, and oral surgery. CBCT scans can help dentists and oral surgeons visualize the teeth, jawbone, and soft tissues in three dimensions, allowing for more accurate diagnosis and treatment planning.
When are Dental CBCTs taken?
Some common situations where dental CBCT scans may be used include:
- Dental implant placement: CBCT scans can provide accurate information about the location, shape, and density of the jawbone to help plan the placement of dental implants.
- Orthodontic treatment planning: CBCT scans can provide detailed information about the position and orientation of the teeth, as well as the underlying bone structure, to help plan orthodontic treatment.
- Evaluation of impacted teeth: CBCT scans can help determine the position and orientation of impacted teeth and identify any potential complications associated with their extraction.
- Diagnosis and treatment of TMJ disorders: CBCT scans can provide detailed images of the temporomandibular joint (TMJ) to help diagnose and plan treatment for TMJ disorders.
- Evaluation of oral pathology: CBCT scans can help identify and evaluate oral pathology, such as cysts, tumors, and lesions.
Your dentist or oral surgeon will determine whether a dental CBCT scan is necessary for your particular dental situation based on your individual needs and medical history.
Is taking a Dental CBCT Safe?
Dental CBCT (cone beam computed tomography) scans are generally considered safe. CBCT machines use a higher dose of radiation than traditional dental X-rays, but the amount of radiation exposure is still relatively low compared to other medical imaging procedures.
As with any medical procedure, it is important to discuss any concerns or questions you may have with your dental professional before undergoing a dental CBCT scan. They can help you understand the risks and benefits of the procedure and determine whether it is the best option for your individual needs.
