Computed tomography (CT) and cone-beam computed tomography (CBCT) are useful tools for the accurate assessment of medical, dental and orthodontic patients. Traditionally, the diagnosis and treatment planning of these patients have used two-dimensional radiographs. The clinical value of CT and CBCT lies in their ability to provide comprehensive information about anatomical relationships for improved diagnosis, treatment planning and a prediction of treatment outcomes. This book includes new research from authors across the globe, with a focus on aiding researchers and practicing professionals on the use of CT and CBCT.
