Dental Cone Beam Computed Tomography (CT) is a special type of x-ray equipment used when regular dental or facial x-rays are insufficient. Dr. Finch may use this technology to produce three dimensional (3-D) images of your teeth, soft tissues, nerve pathways and bone in a single scan.
The most common uses of the Dental Cone Beam
Dental cone beam CT is commonly used for treatment planning of orthodontic issues. Dr. Finch may also use this advanced technology for more complex cases that involve:
- Surgical planning for impacted teeth.
- Diagnosing temporomandibular joint disorder (TMJ).
- Accurate placement of dental implants.
- Evaluation of the jaw, sinuses, nerve canals and nasal cavity.
- Detecting, measuring and treating jaw tumors.
- Determining bone structure and tooth orientation.
During a cone beam CT examination, the C-arm or gantry rotates around the head in a complete 360-degree rotation while capturing multiple images from different angles that are reconstructed to create a single 3-D image. The x-ray source and detector are mounted on opposite sides of the revolving C-arm or gantry and rotate in unison. In a single rotation, the detector can generate anywhere between 150 to 200 high resolution two-dimensional (2-D) images, which are then digitally combined to form a 3-D image that can provide your dentist or oral surgeon with valuable information about your oral and craniofacial health.
Primary Benefits of Cone Beam Technology
- The focused x-ray beam reduces scatter radiation, resulting in better image quality.
- Makes Placement of Dental Implants More Reliable.
- A single scan produces a wide variety of views and angles that can be manipulated to provide a more complete evaluation.
- Cone beam CT scans provide more information that conventional dental x-ray, allowing for more precise treatment planning.
- CT scanning is painless, noninvasive and accurate.
- A major advantage of CT is its ability to image bone and soft tissue at the same time.
- No radiation remains in a patient’s body after a CT examination.
- X-rays used in CT scans should have no immediate side effects.
