Summary

Although an intraoral scanner IOS can offer the clinician a completely digital workflow, achieving trustworthy digital scans in edentulous jaws is challenging because of the lack of fixed anatomical landmarks. From this perspective, several methods have been proposed to improve the accuracy of digital scanning, however, related results remain inconclusive, and previously proposed devices have had limitations, such as bulkiness, excessive manufacturing requirements, and poor commercial applicability.

Thus, this study aims to clinically compare the effect of conventional versus photogrammetry intraoral scanning methods on the passive fit of mandibular all-on four screw-retained frameworks.

Conditions

  • Completely Edentulous

Interventions

DEVICE

The Photogrammetry-assisted intraoral scanning

The Photogrammetry-assisted intraoral scanning; will be executed using the MUA-compatible ioConnect ® photogrammetry system components exactly in the same sequence as recommended by the manufacturer

DEVICE

The modified approach of splinting-assisted intraoral scanning

The scan bodies will be mounted over the MUA and loosely connected with a power chain before the Medit scanner single-shot scanning procedure. Using the additional scan option in the Medit scanner software, another single-shot scan will be obtained and superimposed to the first scan yielding a color map that reflects the accuracy of the obtained scan and directs a highly precise final scan.

DEVICE

Simple splinting-assisted intraoral scanning

The Medit i600 direct intraoral classical scans will be obtained while applying only a basic simple splinting
