A 3D CT scan gives you information in all three planes so you can see the volume of the bone rather than just a 2D image, which can be limited. Furthermore, you can take measurements in all three dimensions, decide on the ideal site for placement and thus choose the most appropriate length and type of implant to use – as well as determining whether any kind of bone graft is necessary.
CT scan data can be used in other dental technologies to assist accuracy in diagnosis and implant planning: in particular, implant guided systems where virtual implants can be placed on-screen and in many cases a custom-made drill guide can be fabricated for use in surgery. Anatomical models (3D replicas of the patient’s jaws) can be made from the data – these models can be drilled into and actual implants can be placed.
Cone Beam CT scanning
CBCT is accurate and cost-effective with a low radiation dose. Usually, these scans are taken with the patient upright (rather than supine in a conventional CT scanner) – this preserves the natural position of the teeth as well as being reassuring for anxious or claustrophobic patients. Most CBCT scanners can limit the field of view and thus the radiation exposure. Small volume scans continue this idea, and some scanners can image a single tooth.
