Comparison of the Accuracy of Panoramic View in CBCT with Ondemand Software in Determination Indicators Used in Maxillary Posterior Toothless Implants Treatment

Due to the increasing population of the elderly and the ever-increasing need for evaluating dental implants preoperatively, it is necessary to find a method with the best diagnostic accuracy. Therefore, this study aimed to compare the accuracy of panoramic views of CBCT radiography using Ondemand software in determining the indices used in the implant treatment planning of the edentulous posterior maxilla.

This cross-sectional, descriptive/analytical study was performed on CBCT radiographs of 43 patients (113 teeth) requiring implants in the archives of a private radiology center. Two panoramic and cross-sectional views were compared in each CBCT radiograph to compare different variables, including ridge height, pathologic entities, septa, and sinus lift requirement. McNemar test and Paired t-test were used for data analysis. The significance level was considered at p value = 0.05.

The results showed no significant differences in the means and standard deviations of the height of the residual ridge between panoramic and cross-sectional CBCT views in any of the teeth studied (p value = 0.113). Maxillary sinus septa, the need for a sinus lift procedure, and probable pathologic entities were not significantly different between panoramic and cross-sectional CBCT views (p value = 0.99).

Under the limitations of the present study, it can be concluded that both panoramic and cross-sectional views are highly accurate in assessing the ridge height, septa, pathologic entities, and need for a sinus lift procedure.
