Influence of the Accuracy of Intraoral Scanbodies on Implant Position: Differences in Manufacturing Tolerances

Purpose: To assess the manufacturing tolerances of three different intraoral scanbodies (ISBs) and their possible influence on the transfer of the intraoral implant position to the digital cast. Materials and Methods: Three different ISBs were measured using x-ray computed tomography. The length, diameter, angle, and target volume deviation were analyzed, and the data were subjected to a univariate analysis of variance. Results: There were significant differences between all three ISBs in length, diameter, and target volume deviations (P .05). Conclusion: Manufacturing tolerances of ISBs have the potential to decisively affect the transfer accuracy of the implant position from the recorded intraoral position to the digital cast, which needs to be considered.
