Accuracy of Intraoral Photogrammetry vs Optical Scanners for Immediate Full-Arch Implant Loading

NCT07320729 · Status: ACTIVE_NOT_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 4

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.

Conditions

  • Edentulism
  • Implant-supported Full-arch Prosthesis
  • Digital Impression Accuracy
  • Photogrammetry in Dentistry

Interventions

DEVICE

Intraoral Optical Scanner

Digital intraoral scanning of implant positions using standard scan bodies for complete-arch implant impressions.

DEVICE

Intraoral Photogrammetry Scanner Elite (Shining3D)

Intraoral photogrammetric capture of implant coordinates using scan flags, combined with soft tissue scanning, without stitching.
