Cone Beam Imaging Facility

Take a look at 3-D facial imaging

The Indiana University School of Dentistry provides scanning services by appointment. While the primary purpose of our cone beam imaging facility is to improve the quality of care for our own patients, we welcome referrals from clinicians in the community. Contact us via email or phone to request a patient referral form.

All scans performed in our facility are interpreted by a board-certified oral and maxillofacial radiologist on our faculty, and a detailed interpretation report is generated for every patient scan.

What is cone beam imaging?

Dental cone beam computed tomography (CBCT) provides anatomical image data similar to a medical CT scan. While a patient receives much more radiation with a cone beam scan than with other standard dental imaging methods, it is a much lower radiation dose than a medical scan.

A 3-D image is made with one scan sweep around the patient using a cone-shaped X-ray beam, resulting in several hundred dimensionally accurate images. Computer software reconstructs these images into multiplanar views at a 1:1 ratio.

While CBCT generates accurate measurements that are essential for implant placement or other treatment that requires precision, it is not appropriate for diagnosis of dental caries or other fine details that are more easily seen through standard dental imaging.

Why use cone beam imaging?

  • Developing anatomically and dimensionally accurate 3-D craniofacial records for orthodontia
  • Evaluating impacted mandibular third molars and other teeth
  • Assessing the location of the inferior alveolar canal prior to surgery
  • Identifying root resorption
  • Evaluating pathological lesions
  • Assessing condyle-fossa position and dentition in the same image field of view to verify the anatomical relationship of these structures
  • Evaluating the paranasal sinuses and other airway spaces for obstruction, inflammatory conditions, or pathology
