title: Three-dimensional imaging cone bean computer tomography technology: an update and case report of an impacted incisor in a mixed dentition patient.
abstract: The current 3-dimensional (3-D) technology termed "cone beam computer tomography" (CBCT) provides accurate 3-D anatomical image data similar to medical computerized tomography but at a lower cost and dose. CBCT has been suggested to be used in cases of supernumeraries because it yields accurate 3-D information relative to the orientation, sagittal position, local disorders, and neighboring anatomic structures. The purposes of this article were to: present the available 3-D imaging technology; and report the case of a patient in the late mixed dentition with a maxillary supernumerary tooth and an impacted central incisor. The use of a CBCT appears to be favorable as a diagnostic and communication tool for cases of impacted teeth in the mixed dentition that are candidates for orthodontic resolution.
