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

NCT07320729 | Active Not Recruiting

• 1 other identifier: 17-2025-00027

Brief 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

Outcome Measures

Primary Outcomes (1)

• 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).

  3 Months

Secondary Outcomes (1)

• Effect of Arch Type on Digital Impression Trueness

  3 Months

Study Arms (2)

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.

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.

Device: Intraoral Photogrammetry Scanner Elite (Shining3D)

Interventions

Intraoral Optical Scanner DEVICE

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

Intraoral Optical Scanner (IOS)

Intraoral Photogrammetry Scanner Elite (Shining3D) DEVICE
