At The Dental Studio Miami we use the cone beam computed tomography (CT) is a special type of x-ray machine used in situations where regular dental or facial x-rays are not sufficient. It is not used routinely because the radiation exposure from this scanner is significantly more than regular dental x-rays.
This type of CT scanner uses a special type of technology to generate three dimensional (3-D) images of dental structures, soft tissues, nerve paths and bone in the craniofacial region in a single scan. Images obtained with cone beam CT allow for more precise treatment planning.
A cone beam CT examination requires no special preparation.
Prior to the examination, you may be asked to remove anything that may interfere with the imaging, including metal objects, such as jewelry, eyeglasses, hairpins and hearing aids. Although removable dental work may need to be removed, it is advisable to bring these to your examination, as your dentist or oral surgeon may need to examine these as well.
Women should always inform their dentist or oral surgeon if there is any possibility that they are pregnant. See the Safety page for more information about pregnancy and x-rays.
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.
- The focused x-ray beam reduces scatter radiation, resulting in better image quality.
- 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.
- There is always a slight chance of cancer from excessive exposure to radiation. However, the benefit of an accurate diagnosis far outweighs the risk.
- Because children are more sensitive to radiation, they should have a CT exam only if it is essential for making a diagnosis and should not have repeated CT exams unless absolutely necessary. CT scans in children should always be done with low-dose technique.
Cone beam CT scanning, otherwise known as Cone beam computed tomography, is a medical imaging technique that consists of capturing three dimensional (3D) images of the patient’s mouth, jaw, nose, ears and throat. Compared to a conventional CT scanner, the use of a cone shaped x-ray beam dramatically reduces the amount of radiation that is emitted from the scanner, making it much safer for the patient. In dentistry, the Cone Beam CT scanner is used when regular facial radiographs (x-rays) are not sufficient enough. Because it is quick and efficient, this technological advancement has become an important tool in the treatment planning and diagnosis in the context of implant surgery, the evaluation of potential abnormalities in a patient’s teeth, visualizing and diagnosing dental trauma and in several other applications.
Using 3D CBCT scanners, we can ensure that the implants are surgically placed in a manner that compliments your natural oral anatomy and the long term success of the procedure.
