CBCT 3D X-ray
A dental cone beam computed tomography machine, or CBCT machine, is a highly specialized type ofdental X-ray machine that produces 3D images of the teeth, bone structure, surrounding tissue, and nerve paths in a single scan.
What are the most common uses for CBCT x-rays?
CBCT x-rays are most commonly used for procedures in which other kinds of X-ray images would not provide sufficient information.
The most common situations CBCT x-rays are used:
Oral or reconstructive surgery planning
Diagnosing TMJ disorders
Dental implant placements
Evaluations of the nasal cavity, sinuses, nerve pathways, and jaw
What is the radiation exposure of a CBCT x-ray?
Depending on the imaging detector, the field of view, and voxel sizes used for scanning, CBCT radiation exposure can range from 19 µSv to 1073 µSv.
Generally, the radiation exposure from CBCT x-rays is lower than other CT exams. However, they tend to deliver more radiation than 2D dental x-ray exams.
