Accuracy of Complete-Arch Implant Photogrammetry
Sponsor: Menoufia University
Summary
This prospective comparative clinical study evaluated the accuracy and chairside time of complete-arch implant scans obtained using an intraoral photogrammetry system and a mobile-phone-based photogrammetry system in edentulous patients rehabilitated with complete-arch implant-supported prostheses. Implant positions recorded by each system were compared with a reference dataset to assess linear and angular discrepancies. The chairside time required for data acquisition was also measured. The study aimed to determine whether mobile-phone-based photogrammetry can provide clinically acceptable accuracy comparable to that of intraoral photogrammetry while improving clinical efficiency. The findings may help clinicians select appropriate digital impression techniques for complete-arch implant rehabilitation.

Interventions
Intraoral Photogrammetry (IPG)
A photogrammetry-based digital impression system used to capture the three-dimensional positions of implants in complete-arch rehabilitations. The system records implant locations through specialized scan bodies and generates a digital dataset for subsequent accuracy analysis.
Mobile-Phone-Based Photogrammetry
A smartphone-assisted photogrammetry system used to capture the three-dimensional positions of implants in complete-arch rehabilitations. The system acquires photographic data through coded markers and generates a digital dataset for subsequent accuracy analysis.
