Abstract
Purpose: Radiological evaluation of bone quality as well as the shape of the alveolar bone of the
edentulous part to be placed is very important f or successf ul implant placement. Recently, threedimensional
analysis using computed tomography and cone beam computed tomography has been
actively used before implant surgery, but periapical and panoramic radiographs have been used
for a long time to evaluate alveolar bone using low radiation doses. The purpose of this study was
to compare the Hounsfield unit value of CT after dividing maxillary, mandibular, anterior, and
posterior teeth into whether periapical and panoramic radiographs could be effectively used for bone
quality evaluation.
Materials and Methods: The periapical x-ray, panoramic x-ray, and conventional CT were taken
from a total of 100 patients who have undergone the implant treatment. For 3D analysis, the virtual
implants with a diameter of 4 mm and a length of 10 mm were placed in the implant planning
software and the bone quality of 1 mm circumference was measured by Hounsfield unit value.
Periapical x-ray and panoramic x-ray were also evaluated for bone quality. The degree of agreement
among them was evaluated.
Results: In 3D image analysis, reformatted cross-sectional, panoramic image analysis, bony quality
evaluation similar to CT analysis was possible in maxillary anterior/posterior teeth with periapical and panoramic radiographs.
Conclusion: Periapical and panoramic radiographs could be used to evaluate the implant bone quality of the
maxillary anterior and maxillary posterior.
