Abstract
The efficiency of imaging the anterior teeth of panoramic radiography was investigated and compared with that of zonography on SCANORA® using the model of steel balls arranged in lines, and clinical application was attempted.
From the results of this experiment, it was concluded that zonography reproduces shape and position better than dental panorama does.
As a result of applying zonography to a patient that had several buried incisor implants, it not only showed a better result in shape and position but also enabled avoidance of a bad effect of trauma shadows of cervical vertebrae.
