Cone beam computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, or flat panel CT) is a medical imaging technique consisting of X-ray computed tomography. The X-rays are divergent, forming a cone.

CBCT has become increasingly important in treatment planning and diagnosis in implant dentistry and interventional radiology (IR), among other things. Because of the increased access to such technology, CBCT scanners are now proving to be very useful in dentistry, especially in the fields of endodontics and orthodontics. Integrated CBCT is also an important tool for patient positioning, and verification in image guided radiotherapy.

During dental imaging, the CBCT scanner rotates around the patient’s head, obtaining up to nearly 600 distinct images. For Interventional Radiology, the patient is positioned offset to the table so that the region of interest is centered in the field of view for the cone beam. A single 200 degree rotation over the region of interest acquires a volumetric data set. The scanning software collects the data and reconstructs it, producing what is termed a digital volume composed of three-dimensional voxels of anatomical data that can then be manipulated and visualized with specialized software.

More security with 3D in
Implantology e.g., recognizing risk cases and own limitations before performing a surgical procedure, performing implants with minimal invasion, assessing the prosthetic and surgical conditions at the same time
Endodontics e.g. recognizing the finest structures when detecting root fractures and traumas to the dentoalveolar complex, depicting internal and external root resorption, preoperative diagnostics in the case of periapical osseous lesions, preoperative endodontic planning (before apicoectomy)
Oral and maxillofacial surgery e.g., displaced teeth, fracture diagnostics, sinus diagnostics, cysts, retained roots, orthognathic surgical procedures
Orthodontics e.g., displaced, impacted teeth, cephalometric analysis, root resorptions, and cleft lips, jaws and palates
General dentistry e.g, contradictory findings, as well as those that are difficult or impossible to view in the OPG, apical lucency, periodontal diseases, patient consultations, endodontics, implantology, oral surgeries

 

GALILEOS ensures the lowest effective dose* with the best image quality. By choosing a smaller volume you can lower the dose even further. The optional HD mode of the GALILEOS ComfortPLUS guarantees the highest image quality so that you will come to a clear diagnosis quickly, even in difficult cases.
