Both traditional computed tomography (CT) scanners and cone-beam CT (CBCT) scanners produce pictures of internal body structures. Secondly, differential diagnosis for such incidental findings should also be provided. Cone beam CT scanners, on the other hand, use a medical fluoroscopy tube, which generates less radiation but still captures incredibly high-resolution radiographs. Regarding peri-implantitis, the diagnosis and severity of the disease should be evaluated . 4. Cone-beam computed tomography systems (CBCT) are a variation of traditional computed tomography (CT) systems. Concerns about radiation exposure are greater for younger patients because they are more sensitive to radiation (i.e., estimates of their lifetime risk for cancer incidence and mortality per unit dose of ionizing radiation are higher) and they have a longer lifetime for ill effects to develop. The process is completely painless, non-invasive, and only takes a few minutes. Reflexionaremos sobre las ventajas y los límites del CBCT, siempre comparándolo con el escáner.
