Abstract

In a panoramic imaging apparatus, a panoramic image is displayed on a monitor. The panoramic image is an image in which an overall dentition is in optimal focus, or an image in which a region of interest that is a portion of the image of the overall dentition is in optimal focus. Both images are reconstructed from frame data that has been collected by an initial first scan. Feature points of one or more teeth and a supporting portion that supports the tooth in the dentition in the panoramic image displayed on the monitor are designated. A length based on the positions of the designated feature points is measured in the panoramic image. The degree of loss in alveolar bone that supports the tooth is analyzed based on the measured length. The analysis information is provided to a dentist as check information regarding periodontal disease.
