Context and Aim: Radiology as well as higher imaging modalities has their own advantages and disadvantages. The present study was designed to do a comparative analysis of the role of cone-beam computed tomography (CBCT) and orthopantomography (OPG) for preoperative planning and postoperative evaluation of treatment outcomes in implant therapy in combination with sinus augmentation procedures. Materials and Methods: Pre- and post-operative assessment of maxillary sinuses was done in 17 patients who underwent implant therapy in combination with sinus augmentation procedures using CBCT and OPG. Statistical Analysis: Statistical analysis was done using IBM SPSS statistics 20 (Chicago, USA). Paired and Unpaired t-tests were used to do a comparative analysis of the two modalities used. Results: There was a concordance between the treatment type based on pre- and post-operative CBCT assessments. The assessment of sinus morphology revealed a significantly higher detection rate of aberrations in the form of sinus mucosal hypertrophy and septae on CBCT which were imperceptible on orthopantomographs undermining the role of routine radiography in these procedures. The results obtained, also, revealed that vertical alveolar bone height could be measured more precisely with CBCT. Conclusion: Based on the findings of the above study, it could be concluded that CBCT increased the accuracy of both, the sinus morphology assessment as well as the estimation of gain in vertical alveolar bone height, in addition to bone density, which remains un-assessed by the conventional radiological techniques including OPG.
