What is CAT and CONE BEAM CT?
The term CAT stands for “computerized axial tomography”, hence “Cone Beam computerized axial tomography”; radiological devices that use this technology release conical x-rays, unlike traditional CATs which emit them in a fan. This new equipment generates high quality images with lower radiation doses compared to those normally administered with conventional CATs (up to 30 times less), obtaining three-dimensional images.
What is it used for?
Volumetric CAT and 3D CBCT are “machines” which in dentistry and maxillofacial surgery are used for 3D diagnoses of the cranial complex.
What difference is there compared to a traditional panoramic dental x-ray?
Analogue and digital orthopantomography, also known as a “panoramic x-ray”, is a 2D examination that provides information on the health of hard tissues in the oral cavity. 3D CONE BEAM technology provides three-dimensional information with similar doses to 2D procedures. This innovative examination provides a virtual reconstruction of the cranium (through the use of 3D rendering software), providing much more information and enabling the Clinician to talk things through with the patient, with clear and intuitive images. 3D CONE BEAM is extremely useful in dental extraction, including wisdom teeth, or implantology operations; these are just some examples, however it has numerous other uses.
What are the advantages?
This new technology offers multiple advantages, including:
a traditional CAT of both dental arches emits a high dose of ionising radiation, whereas 3D Cone Beam emits a much lower amount, up to 30 times less
a single scan is all it takes to obtain “classic” radiographic information, just like in a traditional panoramic x-ray, but it also enables the study of the paranasal sinuses and temporomandibular joint
The most updated software enables the 3D reconstruction of the cranial section, helping the Clinician to obtain very important information on the patient’s anatomy
3D rendering software enables the Professional to clearly communicate with the patient, using the computer to simulate the positioning of implants and future prostheses to be fitted directly on the “virtual jaw”
ithe patient stands (or sits) in front of a machine that is smaller compared to a conventional CAT, eliminating sensations of claustrophobia.
