About this study
Official title: Can Intraoral Photogrammetry Overcome Surgical Field Challenges? An In-Vivo Accuracy Study in Immediate Full-Arch Loading
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.
Read the detailed description
Digital impression systems are widely used for implant dentistry, but complete-arch implant scans remain challenging due to lack of stable landmarks and intraoral movement. Photogrammetry technology captures implant coordinates with high trueness by eliminating stitching errors and excluding unstable soft tissue. A newly introduced intraoral photogrammetry scanner (IPS) integrates photogrammetry and intraoral imaging in a single device.
This study is the first in-vivo prospective clinical trial comparing IOS and IPS accuracy in immediate complete-arch implant loading. Patients receiving 4-6 implants in one arch will undergo two digital impressions immediately after surgery: one using IOS (AoralScan 3) and one using IPS (Elite). A conventional splinted open-tray impression at second-stage surgery will be used as the reference model. Digital files will be superimposed to calculate linear, angular, and 3D (Euclidean) deviations. Scanning time and effect of arch type will also be evaluated.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intraoral Optical ScannerDevice
Digital intraoral scanning of implant positions using standard scan bodies for complete-arch implant impressions.
Intraoral Photogrammetry Scanner Elite (Shining3D)Device
Intraoral photogrammetric capture of implant coordinates using scan flags, combined with soft tissue scanning, without stitching.
| Study group | Role | What they receive |
|---|---|---|
| Intraoral Optical Scanner (IOS) | Experimental | Participants will undergo a digital implant impression using a conventional intraoral optical scanner immediately after implant placement to capture implant positions for immediate full-arch loading. Receives: Device: Intraoral Optical Scanner |
| Intraoral Photogrammetry Scanner (IPS) | Experimental | Participants will undergo a digital implant impression using an intraoral photogrammetry scanner immediately after implant placement to capture implant coordinates using photogrammetric scan flags combined with intraoral soft tissue scanning. Receives: Device: Intraoral Photogrammetry Scanner Elite (Shining3D) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Trueness of Implant Position (3D Euclidean Deviation)
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).
Measured: 3 Months
Secondary outcomes (1)
Effect of Arch Type on Digital Impression Trueness
The secondary outcome is to analyze the potential effect (correlation) of the type of arch (maxilla vs. mandible) on the degree of trueness. Also, the scanning time of the 2 techniques will be compared.
Measured: 3 Months
