In digital implant dentistry, the accuracy of the scanned dental models is important. Error from stitching the same pattern of the edentulous ridge is possible while using intraoral scanners. It could cause a diagonal error of the scanned surfaces that leads to an angular error of the implant axes. The purpose of this study was to investigate the angular error of the scan bodies in different inter-implant distances from using two intraoral scanners. The models of 7- and 14-mm inter-implant distance were prepared. A desktop scanner, 3shape® D900L, was used to prepare the reference data. The Trios3™ and Cerec™ Omnicam intraoral scanners were used to collect test data. Ten scans were performed for each model and scanner. The angular error was, then, analyzed in GOM Inspect™ software and statistical estimation was performed using SPSS 18. Trios3 had median angular errors of 0.390 (0.515, 0.285) and 0.472 (0.620, 0.375) degrees in the 7- and 14-mm groups, respectively, and the result was not statistically significant. The angular errors of Cerec Omnicam were 0.355 (0.455, 0.135) and 0.505 (0.725, 0.305) degrees in the 7- and 14-mm groups, respectively. It was statistically significant for this scanner (p<0.05). There was no statistical difference in the angular error between the two scanners. It is suggested in this study that the large inter-implant distance creates a greater angular error of the scan bodies as computerized data, which could affect the passive fit of the final restorations.
