Conventional scan body vs. scan bodies with auxiliary geometric devices: an in vitro study for edentulous full-arch implant impressions

The AGD, tested under in vitro conditions, significantly improved the trueness of full-arch implant impressions, particularly reducing c- and TotRMS values. These findings highlight the AGD's potential to enhance digital workflows in implant dentistry by mitigating positional discrepancies and ensuring greater trueness and precision. Future research should explore these findings in a clinical scenario.
