Abstract

Statement of the Problem: The mechanisms of operation of Dental Scanners are based on different technologies. Considering these differences, there are many types of scanners available in the market. Purpose: This in vitro study aimed to compare the accuracy (Precision and Trueness) of seven commonly used Dental Scanners. Materials and Method: In this in vitro experimental study, the accuracy of 7 common extra oral scanners (Sirona ineos inLab, Sirona X5, Dentium, Imes Icore 350I, Amann Girrbach, 3shape D700, and 3Shape E3) were evaluated. Each of scanners performed 7 scans of im-plant abutment of SIC (SIC MAX. GH1). Data from each scanner were then compared to data received from 3Shape Trios intra oral scanner as a reference. For evaluating the accura-cy of each scanner, Trueness and Precision was evaluated. Collected data were analyzed using Kruskal Wallis and Bonferroni tests via SPSS version 22. Results: Descriptive statistics showed the best Trueness was for 3Shape E3 scanner with the average of 35. 37μ m and the worst Trueness belonged to Sirona x5 scanner with the average of 51. 75μ m. Furthermore, the best Precision was achieved for 3Shape E3 scanner with the average of 35. 34, while the lowest Precision was detected in 3Shape D700. The scanners had statistically significant differences with each other in terms of Trueness and Precision (p<0. 05). Conclusion: Based on the results of this study, the extra oral scanner, 3shape E3, had the best Trueness and Precision. The lowest amount of Trueness among the studied scanners was for the extra oral scanner, Sirona x5, and the lowest Precision was for scanner 3shape D700.
