Cone-beam computed tomography (CBCT) assists the prosthodontist not only to place the implant in sites which allow optimum restoration, but also minimize complications, such as permanent nerve injury, excessive bleeding in the floor of the mouth and mandibular fracture.

CBCT also assists in the identification of those teeth which are likely to be successfully treated or retreated by the endodontist. Since modern prosthodontics is applicable to patients of all ages, the prosthodontist needs to be aware of the most frequent and important lesions that may present. CBCT is shown itself to be a valuable diagnostic tool for such lesions.


  1. Identify and describe of the components of CBCT and understand their importance.
  2. Determine when CBCT should be prescribed for the restorative patient.
  3. Understand the range of pathology that may present on a CBCT dataset of a restorative patient
  4. Determine when a CBCT dataset should be referred.
