Physicians have relied on computerized axial tomography scans (CAT) for many years. CAT scans are an X-ray procedure that uses many different X-ray images with the help of computers to generate cross-sectional or even 3D views of internal organs and structures within the body.
More recently however, orthodontists have begun to rely on 3D imaging techniques and i-CAT® scans to provide them with a detailed view of the mouth and skull. The advantage that 3D imaging holds over regular dental x-rays is that bone structure, bone density, tissues and nerves can be viewed clearly.
i-CAT® scans are quick and simple to perform…this means that far less radiation enters the body than if a regular set of bitewing X-rays were taken. During the scan, the patient sits stationary on a designated seat and cone beams are used to take hundreds of pictures of the face. These pictures are used to compile an exact 3D image of the inner mechanisms of the face and jaw.
The i-CAT® scan is an incredible tool that can help reduce treatment time and enhance the end results of orthodontic treatment.
