Purpose: There is always a slow but steady evolution occurred in dentistry, resulting in use of osseointegrated dental implants which became widely accepted procedure in the rehabilitation of edentulous spaces. Evaluation of the available alveolar bone dimensions is an important prerequisite for dental implant placement and successful outcome. Hence, this vivo study was designed to evaluate the accuracy of cone beam computed tomography (CBCT) and bone mapping for the diagnostic purpose. Materials and Methods: A total of 27 partially edentulous sites in maxilla and/or mandibular arch were selected according to the mentioned criteria. The width of edentulous spaces was measured and compared by three methods: CBCT, bone mapping, and surgical exposure. Later, the obtained data were sent for statistical analysis to check the accuracy of methods for the assessment of residual alveolar ridge width prior to the dental implant placements. Results: Normality check was done before finalizing statistical tests using Kolmogorov–Smirnov and Shapiro–Wilk test and non-parametric tests were applied for final analysis. Variables were compared using the Wilcoxon signed-Rank Test. Spearman's Rank correlation was obtained to check the relationship between variables. Throughout the result, significance level was fixed at 5% and if value of P < 0.05, it shows a significant result. For this study, P < 0.05 and statistically significant, which show that average measurements are significantly differ between the variables. Conclusion: CBCT and ridge mapping measurements when compared individually with the gold standard, surgical open method, CBCT proved to be a highly accurate method detecting the residual alveolar ridge width in the dental implant treatment planning.
