3Shape TRIOS 3 shows significantly higher precision than Medit i500 in new study

In a just published study, 3Shape TRIOS 3 intraoral scanner outperformed the Medit i500 intraoral scanner for three important criteria. The study found that:

1. 3Shape TRIOS showed significantly higher precision compared to the Medit i500.
2. 3Shape TRIOS showed better scan shape reproducibility than the Medit I500 in all experimental groups.
3. The Medit i500 scanner showed a higher error than the 3Shape TRIOS intraoral scanner in the full-arch reference model.

According to the paper: “The aim of this study was to assess the accuracy of two different intraoral scanners on a specially designed full-arch reference model with several scanning-aid materials. To evaluate the accuracy, 3D superimposition with best-fit alignment and linear measurements of the designated distances on the reference model were used. Additionally, the time efficiency was verified by measuring the scan time. Therefore, the effectiveness of each scanning-aid material for two intraoral scanners was compared and assessed.”
