Truness of Full Arch Impressions in All on x Cases

This study aims to compare the trueness and precision of three impression methodologies photogrammetry, digital intraoral scanning with splinted scan bodies, and conventional open tray impressions in the context of the All-on-X treatment concept. This will provide valuable evidence for clinicians considering digital workflows for implant-supported prostheses. Does the use of photogrammetry and digital impression techniques with splinted scan bodies result in improved accuracy in implant position transfer in the All-on-X concept compared to conventional open tray impressions?
