Panoramic radiography is often the first choice method for the placement of implants because it provides information on the overall shape of the jaws, the position of the maxillary sinus floor and the nasal cavity floor, and the proximal distal as well as vertical position of the mandibular canal and the mental foramen. The measurements on digital radiography are quite acceptable and reliable for clinical use as long as the structures do not traverse the midline. Repeated measurements lead to a reduction in the systematic error and magnification to a loss of accuracy. The study was planned on the Department of Dentistry Anugrah Narayan Magadh Medical College and Hospital, Gaya.on 30 implants in the posterior mandibular regions. The digital panoramic radiographic images were taken using implants in the posterior mandibular regions. The digital panoramic radiographic equipment used. All digital panoramic radiographs were taken by technicians according to standard protocol provided by the manufacturer. This study is aimed to determine the accuracy of the vertical and horizontal measurements on digital panoramic radiographic images using implants in the posterior mandibular regions.
