TL;DR
Both Medit i900 and Dexis IS 3800W provided clinically acceptable accuracy for Kennedy Class I mandibular arches, and accuracy was influenced by scanner type, tip size, and scanned area.
Cavity depth and tooth structure thickness significantly influenced the accuracy of intraoral scanners in endocrown restorations and significantly influenced the accuracy of intraoral scanners in endocrown restorations.
Evaluating how different ISB designs affect the trueness and precision of digital impressions in a completely edentulous maxillary arch with multiple implants found significant differences were found among ISBs in both trueness and precision.
Full-arch intraoral scanning of edentulous models demonstrated clinically acceptable accuracy, within the limitations of this in vitro study, and should be interpreted cautiously when extrapolating to clinical intraoral conditions.
The type of scan body did not significantly affect the accuracy of digital impressions for bone-level implants and the mean and standard deviation of Root Mean Square Eror (RMSE) were calculated.
Scanner accuracy varied significantly, with Primescan and Trios 4 demonstrating superior trueness and precision and iTero and Medit showed reduced accuracy, particularly in angular measurements.
