Dental cone beam computed tomography (CBCT) is a special type of x-ray machine that is implemented in scenarios where normal dental or facial x-rays are insufficient. This variation of the CT scanner employs a special type of technology to generate 3-D images of dental structures, soft tissues, nerve paths, and bone in the craniofacial area, in one scan. These images allow for more specific treatment planning. The CBCT machine has an x-ray beam, in the shape of a cone, which moves around you to create a large number of high-quality images, or views. It was developed as a means to produce similar images to what a CT provides, though with a significantly smaller and less costly machine that could be situated in an outpatient office. Providing detailed images of the bone, the CBCT machine evaluates diseases of the jaw, dentition, bony structures of the face, sinuses, and nasal cavity. One shortcoming is that it does not provide the comprehensive diagnostic information available with conventional CT, especially in the analyzing of soft tissue structures such as muscles, glands, nerves, and lymph nodes. The CBCT machine can also be used for reconstructive surgery, cephalometric analysis, locating the origin of pathology, surgical planning for impacted teeth, diagnosing temporomandibular joint disorder (TMD), and for the accurate placement of dental implants.
