Accuracy of Intraoral Photogrammetry vs Optical Scanners for Immediate Full-Arch Implant Loading
Sponsor: Abdelrahman Khalaf Eldabe
Summary
This prospective in vivo clinical trial evaluates and compares the accuracy (trueness) and scanning time of intraoral photogrammetry scanners (IPS) versus conventional intraoral optical scanners (IOS) for immediate full-arch implant impressions. The reference standard will be a verified conventional splinted open-tray impression taken at the uncovering stage. Sixty edentulous arches receiving 4-6 implants will be included. Linear, angular, and 3D Euclidean deviations will be calculated to assess accuracy.
