What is CBCT?
CBCT stands for Cone Beam Computed Tomography. It is a technology used to take three dimensional (3-D) images of your teeth, maxillary sinus, nerve pathways, and bone in the maxillofacial region with a single scan. The CBCT system rotates around the patient in approximately 30 seconds, capturing data using a cone-shaped x-ray beam.
Dental cone beam computed tomography is used when regular two dimensional dental x-rays are not sufficient. With CBCT, clinicians can get highly detailed 3-D views of the facial region with lower radiation exposure than a conventional CT scan. This may help with the diagnosis, treatment planning and evaluation of certain conditions.
Oral surgeons commonly utilize this technology to assess the following treatment options:
- Accurate placement of dental implants and tooth orientation
- Calculating the size and shape of dental ridge
- Assessment of the quantity and quality of bone
- Evaluation of nasal cavity
- Determining the need for a bone graft or sinus lift
- Surgical planning for impacted teeth
- Detecting inferior alveolar nerve position for removal of lower wisdom teeth
- Locating the origin of pain or pathology
- Detecting, measuring and treating jaw tumors
- Diagnosing temporomandibular joint disorder (TMJ)
- Cleft palate assessment
- Orthognathic surgery planning
