Overview

In vitro study reveals trueness differences between intraoral scanners and photogrammetry, highlighting significance in digital impressions.

Key Points

  • The Medit i500 intraoral scanner showed superior trueness compared to the PIC Dental photogrammetry device.
  • Statistically significant differences were noted in the root mean square values among the devices used for full-arch implant rehabilitation.
  • Options with fewer implants and closer inter-implant distances resulted in enhanced trueness during digital impression acquisition.
  • Best-fit superimpositions confirmed the comparative analysis of digital master casts against virtual models.
