Aim: To compare the abilities of computed tomography (CT), cone beam computed tomography (CBCT) with X-resin and ridge mapping and to measure the thickness of bone and soft tissue during implant planning, which allows increasing the success criteria of implant placement. Materials and Methods: This validity study included a total of 96 samples chosen from 20 patients undergoing implant surgeries (mandible and maxilla) aged between 25 and 50 years. Measurements of bone and mucosa were done by using three techniques, which are the CT, CBCT with X-resin, and finally ridge mapping at 4 points that are 3, 4, 5, and 6 mm from the alveolar crest. The analysis of variance test was used for statistical analysis, establishing a level of significance at P ≤ 0.05. Results: A comparison between the different techniques was done using Freidman’s test with the Wilcoxon signed-rank test for paired (matched) samples as multiple 2-group comparisons. Two-sided P < 0.05 were considered statistically significant. For bone measurements, results showed that there was a statistically significant difference between CBCT and CT and between CBCT and ridge mapping, whereas for soft tissue measurements; results showed that there was no statistically significant difference between ridge mapping and CBCT using the X-resin stent and there was a slight statistically significant difference between the ridge mapping and the CT. Conclusion: The study reveals the ability of CBCT with the X-resin to give accurate measurements not only to the bone but also for the soft tissue in different cases with the least radiation dose and low cost.
