Accuracy of Complete-Arch Implant Photogrammetry
Accuracy of Complete-arch Implant Scans Obtained Using Intraoral Photogrammetry and a Mobile-phone Based Photogrammetry.
연구 개요
상세 설명
Accurate recording of implant positions is essential for the passive fit and long-term success of complete-arch implant-supported prostheses. Photogrammetry-based technologies have emerged as promising alternatives to conventional digital impression techniques for capturing implant positions with high accuracy. While intraoral photogrammetry systems have demonstrated favorable results, the clinical performance of recently introduced mobile-phone-based photogrammetry systems remains insufficiently investigated.
This prospective comparative clinical study aims to evaluate the accuracy and chairside time of complete-arch implant scans obtained using an intraoral photogrammetry system and a mobile-phone-based photogrammetry system in edentulous patients restored with complete-arch implant-supported prostheses. Each participant will undergo implant scanning using both systems according to the manufacturers' recommendations. The resulting digital datasets will be compared with a reference dataset to determine scan accuracy.
The primary outcome measures will be linear and angular discrepancies between the implant positions captured by each photogrammetry system and the reference dataset. Secondary outcome measures will include the chairside time required for scan acquisition. Statistical analyses will be performed to compare the accuracy and efficiency of the evaluated systems.
