Cone Beam CT Scan Imaging
Radiology is an important tool in diagnosing and assessing dental abnormalities in patients. It is especially helpful in treating patients with problems in the dentomaxillofacial region. Cone Beam CT Scan Imaging, also known as CBCT, is considered an important innovation in dental X-ray diagnostics, particularly for dentomaxillofacial surgery. Unlike regular X-rays, CBCT scans can differentiate among many types of tissue including bone, teeth and nerves.
Benefits of CBCT
CBCT has several advantages over traditional scanning which include the following:
High Resolution and 3-D imaging - This enables subtle structures like root canals or the periodontal ligament to be clearly displayed.
Lower Radiation Exposure - CBCT uses significantly lower radiation than traditional CT scans and has a lower rate of image disturbance caused by metallic structures.
Duplicate Imaging - CBCT provides images of both bone and soft tissue at the same time.
Cone Beam CT Scanning is commonly used in surgical planning for displaced or impacted teeth and for pre- and post-operative imaging for surgery. CBCT is also effective in diagnosing or assisting in the treatment of the following:
- Dental implant placement
- Cleft-palate malformations
- Bone and tooth fractures
- Maxillary sinus examination
- Diagnosis of jaw conditions such as temporomandibular joint disorder, or TMJ
- Detection, measurement and treatment of jaw tumors
- Location of the origin of pain
CBCT is an effective tool in assisting dentists with various diagnosis and treatments. Depending on a patient's particular condition, a dentist will decide whether the use of a CBCT is appropriate.
