Scan Time and Prosthetic Complications of Intraoral Scanning Versus Intraoral Photogrammetry for Full-Arch Titanium Framework With Zirconia Overlay Implant Screw-Retained Prostheses
Sponsor: Cairo University
Summary
This study aims to evaluate the effect of intra-oral scanning and intra-oral photogrammetry on scan time and prosthetic complications in patients receiving full-arch titanium framework with zirconium overlay implant screw-retained prostheses. Participants will: Receive a full arch implant prosthesis and scan time will be recorded. Prosthetic complications (e.g., screw loosening, framework fracture, zirconia chipping) will be recorded at 3 and 6-month follow-up period post-delivery and we will manage complications at the time of prosthetic complication occurrence.

Conditions
Interventions
Intraoral photogrammetry (IOP)
IOP will be used in the study to take a digital impression for the implants. The scanner will be used to record the soft tissue anatomy and trans-mucosal abutments. 3D Scan bodies will be fitted on the trans-mucosal abutments that are screwed on the implants to capture their position and scanning will be done. A scan of the soft tissue and scan bodies will finally be conducted.
Intraoral scanner (IOS)
Intra-oral scanner will be used in the study to take a digital impression for the implants. 3D printed generic Scan bodies with unified shape and length replacing the traditional transfer copings will be press fitted on the trans-mucosal abutments and pickup cylinders that are screwed on the implants to capture their position and intra-oral scanning will be done.
