Accuracy of the Calibrated Framework for Full-Arch Implant Impressions in Edentulous Patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this crossover study, researchers compare two implant impression methods in adults who are fully edentulous: a conventional splinted open-tray impression and an intraoral digital scan using a calibrated framework. Each participant receives both techniques after implant placement, enabling within-subject comparison of accuracy. The resulting STL files will be superimposed to evaluate how well each method transfers implant positions and supports a passive prosthetic fit. The goal is to determine if digital scanning with a calibrated framework can provide comparable or superior accuracy while potentially reducing technique sensitivity and time. This work addresses the risk of misfit-related complications in full-arch implant rehabilitation.
