Intraoral radiographs still remain one of the most important imaging modalities available in dentistry to the dental practitioner. The intraoral technique provides high spatial resolution imaging of teeth and potential associated dental and jawbone diseases. With careful attention to calibration and with meticulous technique for detector positioning, intraoral radiographs yield the essential diagnostic information for dental implant planning. In addition to mesio-distal (horizontal) and crestal-apical (vertical) measurements, they provide useful information on bone structure and density.
