Background: OPG is one of the most common imaging methods for routine examination in clinical practice. As it provides only two-dimensional information about the implant sites, especially in relation to buccolingual width of alveolar bone .This measurement of alveolar ridge dimension can be accomplished using ridge-mapping technique. CBCT identifies various anatomical structures three-dimensionally is of great value to the diagnostician. Materials and method: A total of 20 implants were placed in subjects requiring implant placement. A total of 20 patients are advised to get OPG and CBCT done in selected subjects were grouped on the basis of type of treatment plan according to use of radiographic diagnostics aid as: Treatment plan I: according to CBCT only, Treatment plan II: according to OPG and ridge mapping. In 10 patients implant were placed according to treatment plan I whereas in remaining 10 patients implant were placed according to treatment plan II. Results: There was difference in alveolar bone volumes obtained from OPG with ridge mapping and CBCT. The distances measured by OPG with ridge mapping were highly correlated with that measured by CBCT. Conclusion: Radiography plays an important role in implant dentistry. The quality and amount of bone available should be determined during the planning stage. Key words: Implant, Cone beam
