Intraoral Optical Scanner: Digital intraoral scanning of implant positions using standard scan bodies for complete-arch implant impressions.
Intraoral Photogrammetry Scanner Elite (Shining3D): Intraoral photogrammetric capture of implant coordinates using scan flags, combined with soft tissue scanning, without stitching.
Study 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.

Inclusion Criteria:
Completely edentulous arch to receive 4-6 implants. Candidate for immediate loading with a one-piece fixed prosthesis. ASA I or II medically healthy patients. Patient able to attend follow-up visits and sign informed consent.
Exclusion Criteria:
Medically compromised patients (ASA III or higher). Poor oral hygiene or heavy smokers. Insufficient bone volume for implant placement. Uncooperative patients or those refusing participation.
Primary outcome measure(s)
Trueness of Implant Position (3D Euclidean Deviation) — 3 Months The primary outcome is to evaluate the clinical performance of conventional intraoral scanners (IOS) and intraoral photogrammetry scanners (IPS) in immediate complete arch implant loading for each patient enrolled in the study, with a paired comparison of the deviation differences (Degree of Trueness).
