  • Title: Effect of over- and underexposure on the sharpness of the image of a marker in computer-assisted dental implant tomography.
    Author: Thunthy KH.
    Journal: Dentomaxillofac Radiol; 2002 Jul; 31(4):278-80. PubMed ID: 12087446.
    Abstract:
    In dental implant tomography, a clinician typically makes several tomograms of cross-sectional and sagittal slices at and near the intended implantation site. The slice with the sharpest image of the metal marker is deemed to be the correct implantation site; the other slices with blurred images of the marker are those made either mesially or distally to the marker. However, if the images were over- or underexposed, the marker will be blurred on all the slices and a dentist may be wrongly accused of having placed a dental implant at an improper site with possible medico-legal ramifications.
