Evaluating the accuracy of intraoral scanners used in single-unit implant prosthesis construction.

Aim: This study aims to evaluate and compare the scanning accuracy of various intraoral scanners when taking digital impressions of single-implantsupported prostheses. Methodology: A partially edentulous model with a single implant was produced, and a scan body was fixed on the model. The control model was created by scanning the model using Ineos X5 (CM). The model was also scanned (n = 3) using three different intraoral scanners (IOS) [(Helios (H), TRIOS 3 (T3), Medit (M)]. GOM Inspect software was used for comparison. The data were analyzed with a Shapiro–Wilk test, resulting in a nonnormal distribution, and Kruskal–Wallis test was employed for intergroup parameter comparisons. Results: There were significant differences in the devices’ accuracy values (p < 0.05). Accuracy [M (19.1 μm), T3 (25.3 μm), H (33.9 μm)] and sensitivity values [M (10 μm), T3 (19.05 μm), H (25 μm)] are similarly listed from high to low as M, T3, and H. Conclusion: IOS can be used to create digital impressions for single-unit implant crowns. Clinicians should be cautious and selective when choosing IOS for more successful and accurate impressions. More comprehensive and clinical studies using different brands are needed on this subject. [ABSTRACT FROM AUTHOR]
