The aim of this study was to evaluate diagnostic accuracy and clinical value in prediction of maxillary sinus width, through the
comparison of measurements in panoramic radiography and buccopalatal width in CBCT image.
The following anatomic factors are measured from panoramic radiography; 1)residual alveolar bone height, 2)maximum vertical
height of maxillary sinus, 3)maximum anteroposterior diameter of maxillary sinus, 4)shape of maxillary sinus floor(smooth or
scalloped), 5)the number of missing molars. Buccopalatal width was also measured on CBCT. The statistical analysis was
performed to investigate correlation between buccopalatal width on CBCT and panoramic radiography.
The residual alveolar bone height, maximum vertical height and AP diameter of maxillary sinus measured on panoramic
radiography were significantly related with buccopalatal width of maxillary sinus measured on CBCT. However, there were no
significant relevance in the shape of sinus floor and the number of missing molars comparing with buccopalatal width of maxillary
It is considered that residual alveolar bone height, maximum vertical height and AP diameter of maxillary sinus on panoramic
radiography can be utilized for prediction of buccopalatal sinus width. [THE JOURNAL OF THE KOREAN ACADEMY OF
