SUMMARY:

In this laboratory study, the accuracy of digital models generated by two scanning techniques of an experimental model of the upper arch made of polyurethane and of the plaster model obtained from this arch were evaluated. Reference measurements, which were demarcated by the manufacturer, were performed using surgical simulation software and analyzed for validity and accuracy of the scanning techniques used in all groups (1 to 5). In the validation analysis, all techniques were shown to be valid when compared to the control group, with the exception of the FG measure, which showed statistically significant differences (p<0.05) between groups 1 and 2. Precision was assessed using the intraclass correlation index and all techniques were highly accurate with an ICC close to 1. Thus, it is concluded that the intraoral scanner and the desktop scanner used in this study were reliable when compared to the control group and that the two scanner models used presented themselves with high precision.
