Cone-beam 3D CT scans are the newest medical imaging technique in the world of dentistry. They have become increasingly important in treatment planning and diagnosis. During dental imaging, the Cone-beam CT scanner rotates around the patient’s head, obtaining up to nearly 600 distinct images. This data is used to reconstruct a three-dimensional (3D) image of the following regions of the patient’s anatomy: dental (teeth); oral and maxillofacial region (mouth, jaw and neck); and ears, nose, and throat (ENT).

Dental 3D CT ScanWhat Will My Dentist Use Them For?

Your dentist will want to make sure that you, as the patient, are getting the best treatment possible. This includes making sure that they have the best technology to diagnose dental treatments.
Cone-beam 3D scans can help your dentist better diagnose:

  • Dental Implants – Implant placement, quantity and quality of bone, need for bone grafts or sinus lifts
  • Oral Surgery – Impacted wisdom teeth, evaluation of facial fractures and asymmetry
  • Orthodontics – Cleft palate, root angulations
  • TMJ – Osseous structures of TMJ
  • Root Canals – Identification of root canal system anomalies and determination of root curvature

Are Digital X-Rays Safe?

We are all exposed to natural radiation in our environment. Studies show that the radiation exposure from traditional bite-wing x-rays is about 1/100th of the amount of radiation obtained from natural sources in the U.S. each year. Furthermore, digital x-rays produce 80-90% less radiation compared to traditional dental x-rays. Not only are digital x-rays better for the health and safety of the patients, but they are also faster and more comfortable to take, which reduces your time in the dental office. Also, since the digital image is captured electronically, there is no need to develop the x-rays, thus eliminating the disposal of harmful waste and chemicals into the environment.
